  • Patent number: 6086607
    Abstract: A system including an adaptor and a syringe is used for facilitating hemostasis of a biopsy tract or other puncture wound by delivery of an absorbable sponge in a hydrated state into the wound. The adaptor includes a tapered lumen for hydrating and compressing the relatively large absorbable sponge for delivery through a relatively small cannula, such as a biopsy needle. The hydrated absorbable sponge is injected through the biopsy needle into the biopsy tract by fluid. Alternatively, the sponge may be delivered to the biopsy needle by injection of fluid and then delivered to the biopsy tract by a plunger or stylet. The implanted absorbable sponge facilitates hemostasis at the biopsy site or other puncture wound and minimizes the chance of internal bleeding. The absorbable sponge material is absorbed by the body over time.

  • Patent number: 6066148
    Abstract: A method and apparatus for establishing an end-to-side anastomosis by using an instrument (501) is disclosed. The instrument has a passage (502D) for a bypass vessel, terminated by a circumferential anvil (502A, 503B), about which the end of the bypass vessel may be everted and then inserted through an anastomosis opening in a second vessel, such as a coronary artery. After insertion, the tissue edges to be joined are first clamped together by clamping slides (505) and then stapled together by stapling plungers (506) so as to interconnect the two vessels. The stapling plungers (506) are arranged to move at an angle to the passage (502D) instead of parallel to it. With this arrangement, it is possible to use a greater number of staples than has been possible in previous related methods. Preferably also, the instrument is adapted to be divided lengthwise of the passage (502D).
