  • Publication number: 20010001122
    Abstract: A system for performing an end-to-side vascular anastomosis, including an anastomosis device, an application instrument and methods for performing a vascular anastomosis. The system is applicable for performing an anastomosis between a vascular graft and the ascending aorta in coronary artery bypass surgery, particularly in port-access CABG surgery. A first aspect of the invention includes a vascular anastomosis staple. A first configuration has two parts: an anchor member, forming the attachment with the target vessel wall and a coupling member, forming the attachment with the bypass graft vessel. The anastomosis is completed by inserting the coupling member, with the graft vessel attached, into the anchor member. A second configuration combines the functions of the anchor member and the coupling member into a one-piece anastomosis staple.

  • Patent number: 6214020
    Abstract: An implantable prosthesis and device and method for loading and delivering the implantable prosthesis to a trocar cannula. The implantable prosthesis includes a body portion sufficient to extend across and occlude a defect opening and a semi-rigid ring for supporting the body portion. The implantable prosthesis may be provided with a sufficient hoop strength to prevent the body portion from collapsing into the defect opening. A loading and delivery tool includes a main body with a lumen sized to collapse the implantable prosthesis. An elongated shaft is rotatable to wind the implant into a slender configuration and axially movable to advance the rolled-up implant into the trocar cannula. A cartridge extends from the main body and holds the implant in a normal expanded configuration.

  • Patent number: 5904693
    Abstract: A laparoscopic ligation clip applicator for automatically applying a plurality of ligation clips includes a handle assembly having an actuator, an elongated shaft connected to the handle assembly, and an actuating mechanism disposed within the shaft. The actuating mechanism includes a clamp for engaging a first piece of the ligation clip and a slidable driver for driving a second piece of the ligation clip relative to the first piece. The actuating mechanism also includes a hold for preventing rearward movement of the ligation clips, and an advancer for sequentially feeding the ligation clips. A slidable cam, operably connected to the handle assembly, actuates the clamp, the driver and the advancer.

  • Patent number: 5554148
    Abstract: Refillable immunoisolatory neurological therapy devices for local and controlled delivery of a biologically active factor to the brain of a patient. The devices include a cell chamber adapted for infusion with nsecretory cells and having at least one semipermeable or permselective surface across which biologically active factors secreted by the cells can be delivered to the brain. The devices also include means for introducing secretory cells into the cell chamber, and means for renewing the cells or cell medium.

  • Patent number: 5395034
    Abstract: A linear surgical stapling instrument includes a magazine for holding a plurality of undeformed surgical staples, and an upper jaw carrying the magazine and having opposed distal and proximal ends. An anvil is formed with staple-deforming pockets, and a lower jaw carries the anvil and has opposing distal and proximal ends respectively configured to mate with the distal and proximal ends of the upper jaw thereby to place the magazine and the anvil in confronting relation. A staple driver is carried in the upper jaw for driving staples held therein toward the anvil. Further, the upper and lower jaws are configured such that, when their respective distal and proximal ends are mated, a gap exists between the jaws in an intermediate region between their respective distal and proximal ends.

  • Patent number: 4562839
    Abstract: An instrument for applying clips to a surgical site has an applicator with two jaws which are movable between open and closed positions. A mechanism is provided for feeding the respectively leading clip of a string of such clips between the jaws, whereupon the jaws are closed and the leading clip is cinched as it is being applied to the surgical site. To vary the presentation of the clip, i.e., its orientation relative to the surgical site, the mechanism is mounted so that it can turn about a longitudinal axis of the instrument. In one embodiment, a slide button is provided which can be slid forward and backward with one finger of a user, such translatory movement of the button being converted into a turning movement of the mechanism and consequently also of the clip which is being held between the anvils preparatory to its application to the surgical site. In another embodiment, turning movement is effected by rotating a knob secured to the mechanism.
