Publication number: 20070119900Abstract: An improved surgical fastener applying apparatus includes a cartridge half-section and an anvil half-section with the cartridge and anvil half-sections being relatively movable from an unclamped position to a fully clamped position. The apparatus includes a replaceable staple cartridge assembly having a plurality of surgical staples and a pivotably mounted safety lock-out. The safety lock-out is pivotable between an initial position in which a relative movement of the cartridge and anvil half-sections to the fully clamped position is permitted and a blocking position in which a relative movement of the cartridge and anvil half-sections to return them to their fully clamped position after the plurality of staples have been at least partially fired is prevented. The apparatus further includes a pivotably mounted firing lever for moving a pair of camming surfaces longitudinally.Type: ApplicationFiled: January 29, 2007Publication date: May 31, 2007Inventors: Karl Ehrenfels, David Ivanko, Randolph Lehn, Roberto Pedros, Csaba Rethy, Frank Viola

Patent number: 6436054Abstract: A biopsy system is provided including a housing and a biopsy instrument operatively associated with the housing and configured and dimensioned to remove a tissue sample from a patient. A firing module is included that is detachably engageable with the housing and operatively associated with the biopsy instrument to facilitate selective rapid advancement of at least a portion of the biopsy instrument toward a targeted location with the patient. The biopsy instrument includes a tissue receiving portion. The system may include an indexing assembly disposed within the housing and configured to cooperate with the biopsy instrument to selectively orient the tissue receiving portion. The indexing assembly may include a manual gearing assembly configured for selective orientation of the tissue receiving portion. The system may include a linear advancement control assembly disposed within the housing and configured to effect linear actuation of a tubular knife member.Type: GrantFiled: November 24, 1999Date of Patent: August 20, 2002Assignee: United States Surgical CorporationInventors: Frank Viola, Csaba L.

Patent number: 6394982Abstract: A fibrin glue applicator system (10) is provided for dispensing a first and a second protein solution which form a biological adhesive when intermixed on an application site. The fibrin glue applicator system (10) includes a coupler interface (16), a disposable loading unit (DLU) (14), and a housing (12) having a handle portion (20) which includes a trigger (22) operatively associated with a slide bar (36) for dispensing the solutions from the DLU (14). Each piercer (66) is fluid communication with one of the two cylinders (46) of the DLU (14) via a respective conduit (64) connected to a respective main conduit (60). A first one-way valve (68) is included within each conduit (64) to open, and close a path leading from the piercer (66) to the main conduit (60). A second one-way valve (70) is fixed within each main conduit (60) in proximity to each dispensing orifice to open, and close a path leading from each cylinder (46) to its corresponding dispensing orifice.Type: GrantFiled: January 31, 2000Date of Patent: May 28, 2002Assignee: United States Surgical CorporationInventor: Karl Ehrenfels
