Patent number: 5514149Abstract: The surgical clip applicator has a pusher bar which positions the foremost clip from a clip carrier into a ready-to-fire position between the jaws prior to squeezing of the handles together. When the applicator is fired, the previously positioned surgical clip can be crimped about a vessel and when the jaws are released, a new clip is placed between the jaws for the next firing. A channel assembly moves over the jaws to close the jaws while the pusher bar is retracted into the clip carrier for delivering the foremost clip from the carrier upon release of the handles. A latch arrangement is provided for locking the channel asesmbly in place and the handles against movement should the clip carrier be empty.Type: GrantFiled: July 22, 1994Date of Patent: May 7, 1996Assignee: United States Surgical CorporationInventors: David T.

Patent number: 5489287Abstract: A surgical apparatus is disclosed for attaching adjacent end portions of cutaneous body tissue wherein a pair of opposed jaws have means for moving the jaws toward and away from each other. Body tissue engaging means in the form of sharp tip members extend from each jaw and toward the other so as to engage the opposed portions of cutaneous tissue when the jaws are positioned thereagainst and moved toward each other. The jaws and the tips are arranged to cause the cutaneous tissue to assume an irregular shape at the interface whereby an elongated rod-like member, preferably rectangular in cross section, may be directed generally medially of the interface of the tissue to attach the opposed portions to thereby permit healing. The elongated member may have indentations to improve retention within the tissue. A tapered distal end of the elongated member has a pointed tip to facilitate penetration into the tissue.Type: GrantFiled: February 10, 1994Date of Patent: February 6, 1996Assignee: United States Surgical CorporationInventors: David T. Green, Henry Bolanos

Patent number: 5486190Abstract: A safety trocar is provided in which the cannula is reciprocally mounted to the cannula housing and reciprocates into the cannula housing when a proximally directed force is applied thereto. The piercing tip is maintained in the exposed position by a latching mechanism associated with the obturator shaft, and is automatically withdrawn into the cannula under the force of a spring when the proximal force is removed from the cannula, the cannula thus advancing distally and releasing the latching mechanism. Penetration force is maintained at a minimum, and safe and efficacious trocar entry is facilitated.Type: GrantFiled: December 7, 1994Date of Patent: January 23, 1996Assignee: United States Surgical CorporationInventor: David T. Green

Patent number: 5484095Abstract: An apparatus is disclosed for endoscopic application of surgical staples for fastening body tissue, especially vascular tissue. The apparatus includes a frame and an elongated endoscopic section connected to the frame and extending distally therefrom. A staple storage cartridge cooperates with the distal end of the endoscopic section and is selectively pivotal by the user. A staple firing mechanism advances an individual staple against an anvil for staple closure. Means are provided to prevent incomplete staple firing. Relative motion between the staple cartridge and the anvil clamps tissue to be stapled therebetween.The endoscopic section may be adapted for rotation about the longitudinal axis of the apparatus. Gaseous seal means located in the endoscopic section prevent escape of insufflating gas through the apparatus.Type: GrantFiled: October 27, 1993Date of Patent: January 16, 1996Assignee: United States Surgical CorporationInventors: David T. Green, Henry Bolanos, Lisa W. Heaton, Mark E. Alari, Ghaleb A. Sater

Patent number: 5482197Abstract: A self contained gas powered endoscopic surgical apparatus is provided for placing lateral lines of surgical fasteners into body tissue. The apparatus includes a frame portion, an elongated portion extending from the frame portion, and an articulating cartridge assembly mounted to a distal end of the elongated portion. An anvil member is operatively associated with the articulating cartridge assembly and has a forming surface thereon against which surgical fasteners are driven as they are ejected from the cartridge assembly. A collar which is provided in the elongated portion translates longitudinally to draw a cable which operates to move the anvil member relative to the cartridge assembly, thereby clamping body tissue to be fastened. A self contained pneumatic system is associated with the frame portion and is actuable to eject the surgical fasteners from the cartridge assembly.Type: GrantFiled: May 17, 1994Date of Patent: January 9, 1996Assignee: United States Surgical CorporationInventors: David T. Green, Keith Ratcliff, Keith L. Milliman, Henry R. Sienkiewicz, Mitchell J. Palmer
