Abstract
A gel cap is loaded on a folded flange of a voice prosthesis which is loaded on an end portion of an inserter, wherein a tip is pressed against a valve flap of the voice prosthesis. The voice prosthesis includes a strap that is stretched for engagement with an attachment portion on the inserter. The voice prosthesis, gel cap, and inserter are inserted into the tracheoesophageal puncture. The patient then swallows fluids to cause the gel cap to dissolve to allow the esophageal flange to deploy, whereby upon deployment of the esophageal flange, the tip of the end portion of the inserter presses the valve flap open, allowing the inserter to move axially relative to the voice prosthesis until a stop collar of the inserter engages the voice prosthesis providing external visual confirmation to the user that the gel cap has dissolved and the esophageal flange has deployed.
Description
- This application is a continuation of U.S. patent application Ser. No. 12/102,090, filed on Apr. 14, 2008. The entire disclosure of the above application is incorporated herein by reference.
- The present disclosure relates to a method and apparatus for the delivery, or placement, of, for example, a voice prosthesis device into a puncture provided in the tracheoesophageal wall of a speech restoration patient.
- The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.
- A speech restoration technique for persons who have had their larynx (voice box) surgically removed is known wherein air from the trachea is diverted from its normal flow path out through the tracheostoma to a flow path through a voice prosthesis providing a more or less permanent passageway to the esophagus. Esophageal speech results. See U.S. Pat. Nos. 4,435,853; 4,614,516; and 4,911,716. Voice prostheses currently in use for providing controlled air pathways through tracheoesophageal punctures incorporate flexible retention collars. The retention collar lies against the esophageal surface of the tracheoesophageal wall to reduce the likelihood of dislodgement of the prosthesis from the puncture. While this configuration substantially improves retention, the presence of the large retention collar makes insertion of a prosthesis more difficult and traumatic to the tissue surrounding the tracheoesophageal puncture. A possibility inherent in difficult or traumatic prosthesis insertion is incomplete insertion. Incomplete insertion may result in aspiration of the prosthesis into the airway. The prosthesis may be expelled by coughing, requiring endoscopic retrieval from the airway. Additionally, concern about prosthesis insertion difficulty may prevent some patients and physicians from employing this method of voice restoration.
- According to an aspect of the invention, a retainer soluble in fluid is provided for atraumatic insertion of a prosthesis into a puncture in the tracheoesophageal wall. The prosthesis includes a cylindrical body and a flexible first flange provided on an outside surface of the cylindrical body. The flange has a use orientation in which it projects generally outwardly from the outside surface of the body and an insertion orientation in which it is resiliently folded toward the axis of the body. The retainer retains the flange in its resiliently folded orientation.
- To reduce the traumatic experience, the esophageal flange can be placed within a dissolvable capsule (referred to herein as “gel cap”) to reduce the overall dimensions and facilitate the insertion through the tracheoesophageal puncture. Once in place, saliva or other liquid can be swallowed to dissolve the capsule and allow the esophageal flange to expand to its normal dimension and secure the voice prosthesis within the tracheoesophageal puncture.
- In order to confirm proper deployment of the esophageal flange, a technician would typically insert a non-tipped end of a cotton swab or other elongated device into the prosthesis device and press against the valve flap at the distal end of the voice prosthesis. If the valve flap can be visually confirmed internally to open without obstruction, the technician could assume that the gel cap had dissolved and that the esophageal flange of the voice prosthesis had deployed to its proper location. This tactile and internal visual confirmation, unfortunately, is not always possible, for example, due to anatomical location of the voice prosthesis or in a voice prosthesis that has two valves. The clinician could also rotate the prosthesis device within the tracheoesophageal puncture to confirm proper deployment of the esophageal flange.
- With the method and apparatus of the present disclosure, the voice prosthesis is inserted into the tracheoesophageal puncture utilizing an inserter. The gel cap is positioned over the esophageal flange which is folded forward within the gel cap to provide ease of insertion into the tracheoesophageal puncture. The inserter includes an end portion which is longer than the voice prosthesis so that the tip of the end portion presses against a valve member of the voice prosthesis which is not allowed to open due to obstruction due to the esophageal flange being folded inward and retained by the gel cap. The prosthesis includes a strap portion which is hooked to a peg on the inserter. The strap portion is stretched so as to bias the voice prosthesis toward the peg. However, due to the valve member of the voice prosthesis being obstructed from opening by the folded flange in front of it, the strap portion of the voice prosthesis is maintained under load until the voice prosthesis is inserted into the tracheoesophageal puncture and the patient is allowed to swallow fluids to cause the gel cap to dissolve, thus permitting the esophageal flange to deploy to its proper position. The deployment of the tracheoesophageal flange removes the obstruction from the valve member such that the valve member is allowed to open and the stretch that is applied to the strap of the voice prosthesis causes the inserter to slide axially relative to the voice prosthesis until a stop collar of the inserter engages an end of the voice prosthesis. The movement of the inserter relative to the voice prosthesis is an external visual indicator to the clinician that the esophageal flange has properly deployed. The insertion technique of the present disclosure is gentler on the fistula, since rotation of the voice prosthesis is not needed for confirmation of flange deployment. Furthermore, the method is easier for the clinician since dissolving of the gel cap and deployment of the valve is verified by the tactile “pop-through” and external visual feedback by inspection of the location of the inserter relative to the voice prosthesis. The method also provides a gauged safe distance of pop through for a safer confirmation technique. A second step of inserting a second device to press against the valve flap is eliminated, thus avoiding a risk of injury to the posterior wall of the esophagus.

- With reference to
FIGS. 1-6 a method and apparatus for inserting a voice prosthesis according to the principles of the present disclosure will now be described. Initially, agel cap 22 is placed over anesophageal flange 24 of avoice prosthesis 26. Thevoice prosthesis 26 includes anesophageal flange 24 and atracheal flange 28 with a generally cylindricalhollow body 30 extending there between.Body 30 is open on bothflanges FIG. 6 ) is disposed withinbody 30. Astrap 32 extends outwardly fromtracheal flange 28.Strap 32 has an opening 33 adjacent its end. The depiction ofvoice prosthesis 26 is representative of typical voice prosthesis. It should be appreciated, however, thatvoice prosthesis 26 can have a different configuration than that shown and still be inserted with the method and apparatus according to the present disclosure. - A
gel cap 22 includes a generallycylindrical body portion 36 and ahemispherical end portion 38.Body portion 36 andend portion 38 define aninterior cavity 40 within whichesophageal flange 24 and a portion ofbody 30 ofvoice prosthesis 26 can be inserted, as shown inFIG. 2 .Gel cap 22 is dissolvable in liquid and facilitates the insertion ofvoice prosthesis 26 into a tracheoesophageal puncture (P) that extends between a trachea (T) and esophagus (E) of a user, as shown inFIG. 6 . A dissolvable gel cap for retaining a flange of a voice prosthesis is disclosed in US RE39,923, which is herein incorporated by reference in its entirety. InFIG. 6 ,gel cap 22 has been dissolved such thatesophageal flange 24 is fully expanded within esophagus 48. Esophageal andtracheal flanges voice prosthesis 26 in the tracheoesophageal puncture (P), as known in the art. - An implement, such as an
inserter 74, can be used to insertvoice prosthesis 26 within tracheoesophageal puncture (P).Inserter 74 includes astem 75 with ahandle 76 at one end thereof. There is aradial stop collar 77 onstem 75 adjacent anend portion 80.Collar 77 limits the distance theend portion 80 ofinserter 74 can be inserted intovoice prosthesis 26. Atip 78 on theend portion 80 ofstem 75 can be tapered to facilitate insertion ofend portion 80 into thevoice prosthesis 26 through the opening in thetracheal flange 28. A strap attachment portion, such as apeg 79, can be mounted on theinserter 74. Thepeg 79 can extend outwardly fromstem 75 betweencollar 77 and handle 76.Peg 79 is configured to receivestrap 32 withpeg 79 extending throughopening 33.Peg 79 is positioned so thatstrap 32 is stretched to engage withpeg 79. The stretching ofstrap 32 helps keepvoice prosthesis 26 oninserter 74 during handling. Theend portion 80 of the inserter is longer than thevoice prosthesis 26 such that when thegel cap 22 is installed on theesophageal flange 24, the foldedesophageal flange 24 obstructs thevalve member 31 from being opened. Thus, thetip 78 of theend portion 80 of theinserter 74 presses against thevalve flap 31 with thestop collar 77 being spaced from the tracheal end of thevoice prosthesis 26, as illustrated inFIG. 4 . The stretch applied to thestrap 32 applies a spring like force for biasing thevoice prosthesis 26 toward thestop collar 77. It should be understood that alternative attachments portions can be used for engaging thestrap 32 in a stretched position. Examples of attachment portions can include a clamp for engaging the strap, a slot for engaging an enlarged section of a strap, or other devices that can engage thestrap 32 in a stretched condition. - With the
voice prosthesis 26 loaded on theinserter 74 and having thegel cap 22 installed on theesophageal flange 24 of thevoice prosthesis 26, as illustrated inFIGS. 3 and 4 , thevoice prosthesis 26 is ready for insertion in the tracheoesophageal puncture P. Upon insertion of thevoice prosthesis 26 into the tracheoesophageal puncture P, the patient is directed to swallow a fluid that is intended to dissolve thegel cap 22. As thegel cap 22 dissolves theesophageal flange 24 is deployed to its radial position as illustrated inFIG. 5 . Simultaneously, the biasing force applied by thestrap 32 causes theinserter 74 to move relative to thevoice prosthesis 26 until thestop collar 77 engages thevoice prosthesis 26 as thetip 78 of the inserter presses thevalve flap 31 open, causing a visual indicator to the clinician that thegel cap 22 has dissolved and theesophageal flange 24 has deployed. - The clinician then removes the
strap 32 from thepeg 79 or other attachment portion of theinserter 74 and theinserter 74 is removed from thevoice prosthesis 26. The clinician optionally may cut thestrap 32 away from thevoice prosthesis 26, and the installation is complete. - With the method and inserter device of the present disclosure, a clinician is provided with an externally visible indicator that the esophagea flange has properly deployed. The method can be used with a single valve or a multi-valve prosthesis, such as that disclosed in U.S. Pat. No. 5,507,809, wherein internal visual verification of opening of the distal valve flap is not possible.
