Abstract
A system of medical devices implantable in the human body using transabdominal gastroscopy surgery to repair failing sphincters and to prevent obesity. A stainless steel non-magnetic spring covered with silicon or other long-term tissue friendly plastic can be installed in place of a natural sphincter by tunneling through a non-functional natural sphincter and pulling the artificial sphincter into the tunnel to form a ring. The device can be tied on the end with suture to form a permanent structure. Without pressure, the device will be continuously closed; however, it will open under natural pressure on it just as a natural sphincter. A intragastric suspended balloon can be sutured into the stomach to cut appetite. The balloon can be roughly the shape of a pepper and take up room in the stomach without closing it off.
Description
- 1. Field of the Invention
- The present invention relates to medical devices for the human stomach and other passages and more particularly an artificial sphincter and a suspended balloon.
- 2. Description of the Problem
- A sphincter is a anatomical structure that typically partially or totally closes off a passage in the human body but opens to allow passages of substances. In particular, there is a sphincter where the esophagus enters the stomach, a sphincter where the lower end of the stomach enters the small intestine, a sphincter to the lower end of the colon (anus) and a sphincter below the urinary bladder.
- Medical conditions can cause any of these sphincters to partially or totally fail. When the sphincter between the esophagus and stomach fails, highly acid liquid and material can reflux back up into the esophagus causing pain and possible damage to the esophagus. When the pyloric sphincter between the stomach and the small intestine fails, food material enters the small intestine before it is in the proper state of digestion. When the anus fails or partially fails, the patient needs to use bags and other means to control unwanted excretion, and failure or weakness of the urinary sphincter causes incontinence.
- It would be advantageous to have an artificial sphincter that could be implanted in the proper location by a general surgeon using transabdominal surgery or gastroscopy assisted by conventional gastroscopy or surgery.
- Obesity is a persistent problem in the U.S. and other developed countries. In some cases, it can be controlled by dieting; however, in other cases more invasive medical procedures are needed.
- For cases where obesity is caused mainly by overeating, It would be advantageous to have a medical device that could be implanted in the human stomach that would take up space and cause the patient to feel full and stop eating sooner.
- The present invention relates to a system of medical devices that can be implanted in the human body using transabdominal endoscopic surgery to repair failing sphincters and to prevent obesity.
- A stainless steel or other medical grade metal or polymer non-magnetic spring covered with silicon or other long-term tissue friendly plastic tubing can be installed in place of a natural sphincter by tunneling through a non-functional natural sphincter and pulling the artificial sphincter into the tunnel to form a ring. The device can be tied on the end with suture to form a permanent structure. Without pressure, the device will be continuously closed; however, it will open under natural pressure on it just as a natural sphincter.
- A intragastric suspended balloon can be sutured into the stomach to cut appetite. The balloon can be roughly the shape of a pepper and take up room in the stomach without closing it off.
- Attention is now directed to several drawings that illustrate features of the present invention:
-
FIG. 1 is a prior art (educational) schematic drawing of a human stomach. -
FIG. 2A shows the artificial sphincter of the present invention installed in the esophagus/FIG. 2B shows a close-up view of the installation. -
FIG. 3 shows the artificial sphincter laid out flat. -
FIG. 4 shows the artificial sphincter in its installed position ready to be tied. -
FIG. 5 shows the intragastric suspended balloon in its installed position. - Several drawings and illustrations have been presented to aid in understanding the present invention. The scope of the present invention is not limited to what is shown in the figures.
- The present invention relates to a system of devices that can be installed using endoscopic surgery. In particular, an artificial sphincter can be installed into any natural sphincter, and an intragastric suspended balloon can be installed in the stomach.
-
FIG. 1 shows the anatomy of the human stomach. The esophagus feeds through a natural sphincter into the cardal orifice of the stomach. At the lower end of the stomach contents leave the stomach for the small intestine through the pyloric sphincter. -
FIG. 2A shows installation of the ring-shapedartificial sphincter 3 of the present invention at the bottom of theesophagus 2 in a tunnel made by the surgeon. The wall of thestomach 1 is shown for reference.FIG. 2B shows a close-up of the installation. It can be seen that sits in the tunneled-out natural sphincter and will function by opening and closing directly as pressure from food descending the esophagus. Without pressure, the device will be continuously closed and prevent gastroesphagal reflux of stomach acid into the esophagus. -
FIG. 3 shows theartificial sphincter 3 laid out flat before installation. A coiledspring 6 runs the length of the device through atube 5. Astring 4 also can attached to each end of thespring 6 and thetube 5 and can be pre-threaded through into device (or the surgeon can thread the device after implantation). The device is covered withsilicon tubing 5 or other long term tissue-friendly polymer. Thetubing 5 should be fairly tight-fitting and match the diameter of thespring 6. - The
spring 6 can be made of non-magnetic stainless steel or other medical grade metal or plastic that will expand from adequate pressure from above or from below. This allows food to enter the stomach from the esophagus during normal eating and for food to exit the stomach during vomiting. Thespring 6 is placed in theplastic tubing 5. - After the artificial sphincter is placed into the tunnel made by the surgeon, non-absorbable
thread 4 should be tied form a tight ring. Embodiments of the invention can also be supplied with the thread pre-installed. - The implantation procedure can be performed by a general surgeon using transabdominal gastroscopy with the assistance of conventional gastroscopy if needed. The surgeon first performs tunneling through the non-functional natural sphincter and then pulls the artificial sphincter into the tunnel. The device can be threaded (or supplied with threads), pulled into a ring, and tied off.

FIG. 4 shows the device ofFIG. 3 in a ring configuration. -
FIG. 5 shows an intragastric suspended balloon for obesity treatment. It is known in the art to place intragastric balloons in the stomach. They have a problem however. Since they typically float freely, they can sometimes produce symptoms of gastric outlet obstruction. The balloon of the present system is shaped and fixed in place in a particular way. The balloon should occupy about ⅔ of the stomach space more or less, and be constructed in the shape of the stomach with theproximal end 20 round and bigger than the distal end gradually tapering down with the distal end 23 into the atrium. The final size of the installed balloon can be controlled by the amount of fluid-normal saline the surgeon injects to inflate the balloon. The proximal end should have a minimum of four non reabsorbedsutures 22 placed around the larger diameter of theproximal end 20. This suture should be attached to the cardia distally from the gasto-esophageal junction with a free length of 1.5 to 2.0 inches. These ties keep the balloon in an adequate position and will not produce gastric obstructive symptoms. With this embodiment of the invention, the patient feels full much sooner than otherwise. - Installation of the balloon should be performed by a general surgeon with transabdominal gastroscopy with the assistance of conventional gastroscopy if necessary. The balloon has an
inflation port 21 that can be inflated through the esophagus or through transabdominal gastroscopy after suturing. The balloon is typically inflated with saline liquid. Any inflating technique that causes the balloon to maintain its shape is within the scope of the present invention. - Evectional removal can be performed by deflating the balloon, cutting the sutures and pulling the balloon out via the esophagus.
- Several descriptions and illustrations have been presented to aid in understanding the present invention. One with skill in the art will realize that numerous changes, variations and additions may be made without departing from the spirit of the invention. Each of these changes and variations is within the scope of the present invention.
