HOLLOW SUTURE MEMBER WITH
RADIOACTIVE SEEDS
Technical Field
This invention relates generally to radioactive seed implantation treatment of prostate cancer, and more specifically concerns a structure for implanting the radioactive seeds in the prostate .
Background of the Invention Radioactive seed implantation treatment of prostate cancer, known as brachytherapy, is an increasingly popular and effective treatment for prostate cancer. In the brachytherapy technique, radioactive seeds are loaded into hollow needles, with the needles then being inserted into the prostate, using ultrasound imaging to guide the insertion process. The radioactive seeds are either positioned independently (not connected) within the needles and hence are located independently within the prostate after they have been moved out of the needle, or they are connected in a string arrangement by being loaded within a hollow, absorbable suture member, such as Vicryl suture.
In the suture arrangement, the individual radioactive seeds positioned therein are spaced apart, typically 1 cm. After the suture is filled with radioactive seeds, it is heated in a fixture to stiffen the suture and stabilize the position of the radioactive seeds therein. Typically, each suture arrangement has a length sufficient to accommodate at least ten radioactive seeds.
The hollow suture/radioactive seed combination was a significant improvement over the independently (unconnected) spaced seed approach, since the independent seeds, even once
located in the prostate, could migrate out of the prostate to various other locations in the body, including the lungs. Migrated seeds can reduce implant quality and also potentially harm the patient. While the hollow suture combination is a significant improvement to the independent seed arrangement, there are disadvantages to the suture combination approach. The heating step which is used to stiffen the suture combination, a necessary step in the process, can degrade the suture material. The suture combination also sometimes jams within the insertion needle, resulting in a collapsing or buckling of the suture combination. This in turn requires removal of the needle from the prostate and the subsequent reloading of the needle with independently positioned seeds. This is a time-consuming and expensive process. In addition, the commonly available ten seed per suture arrangement necessary to fit available fixtures often results in wasted radioactive seeds when seeds are required for a particular implant.
Further, the free end tips of the insertion needles must be plugged prior to the loading of the suture combination into the insertion needle, again a time-consuming process.
Hence, it is desirable to have a radioactive seed/suture arrangement which is simple, does not require a heating step, and which is more reliable in use than current suture embodiments.

Figure 3 shows an insertion needle loaded with the suture combination of the present invention, ready to be inserted into a patient's prostate.
Best Mode for Carrying Out the Invention
Figure 1 shows the radioactive seed suture combination of the present invention. The combination is used in the radioactive seed implantation treatment of prostate cancer, which is explained in detail in U.S. Patent No. 5,938,583, to Peter Grimm. The suture is a conventional absorbable suture member 10, having an internal diameter sufficient to accommodate a plurality of radioactive seeds 12-12, which typically, but not necessarily, are approximately 0.8 mm in diameter and 4.5 mm long. The suture member material is conventional. However, suture member 10 is substantially longer than conventional suture members which are capable of carrying 10 or more radioactive seeds. In the present invention, the length of portion 15 of suture member 10 which extends from the first radioactive seed 16 in the suture member to the free end 22 of the suture member is a substantial distance. In the embodiment shown, it is approximately equal to the length of the hollow insertion needle.
Positioned within suture member 10 are a plurality of spaced radioactive seeds 12-12, separated by individual spacer members 20-20. The number of radioactive seeds in the suture member could be any selected number, in accordance with the particular requirement of the implant. The individual spacer members 20-20 maintain a known separation between adjacent radioactive seeds and produce a sequential, spaced positioning of the radioactive seeds 12 within suture member 10. In the
embodiment shown, spacer members 20 have approximately the same diameter as the radioactive seeds 12 and are also approximately the same length, although this is not necessary to the present invention. The suture material in the embodiment shown is opaque or almost clear so that the seeds and spacers in the suture can be seen. Also, the suture length can be pre-marked to indicate the correct position in the suture for the radioactive seeds and spacers . In the use of the suture combination of the present invention, radioactive seeds 12 and spacer members 20 are moved alternately into suture member 10 from a loading end 21, but only to the point where the innermost radioactive seed 16 is a selected substantial distance from free end 22 of suture member 10. Once the desired number of radioactive seeds and spacers are in place in the suture member, the combination of the suture member, the radioactive loaded seeds and the spacer members is ready to be loaded into a hollow insertion needle 26. The suture member with seeds and spacers does not require a heating or other stiffening step.
The suture member with seeds and spacers is then loaded into a hollow insertion needle 26, as shown in Figure 2, through a hub end 28 thereof. Free end 22 of suture member 10 is moved through insertion needle 26 until the free end exits tip end 30 of the insertion needle 26.
Free end 22 of suture 10 member is then pulled through insertion needle 26 until the first radioactive seed 16 in the suture member is in the vicinity of tip end 30 of the insertion needle 26. The portion of the suture member from the first radioactive seed 16 to the free end thereof is then severed by a knife or the like. The loaded insertion needle is now ready to" be inserted into the prostate of the patient.
After the loaded needle has been inserted, a stylet 31 (Figure 3) is used to push the suture member, with seeds and spacers therein, into the prostate. When this is completed, the insertion needle and stylet 31 are removed from the prostate,
leaving the suture member with seeds and spacers in place in the prostate. The radioactive seeds thus have been placed in a precisely arrayed line, in a particular spaced relationship relative to each other. The seeds are prevented from migrating via the suture member and thus maintain their original alignment in the prostate.
The present invention is advantageous over conventional suture member/seed combinations, since it does not require any heating for stability or other reasons and thus requires no special fixtures to accomplish such heating. Further, the insertion needle does not need to be plugged at its tip end prior to insertion of the suture member, as the suture member initially is drawn out through the open tip end of the insertion needle. Further, the presence of the spacers tends to prevent the suture member from buckling, which in turn reduces the likelihood of the combination of the suture member and the seeds jamming in the insertion needle.
The combination is also relatively inexpensive. Loading time and effort for both the suture member and the insertion needle is decreased, as are and in operating room time and costs. Hence, the present invention has significant advantages over the existing suture member/seed combination.
