Publication number: 20090131871Abstract: Apparatus for forming and enlarging a percutaneous penetration are disclosed. The apparatus includes an elongate dilation member including a radially expandable member having a first cross-sectional area; and an elongate expansion member including a tubular element having a second cross-sectional area which is larger than the first cross-sectional area. The apparatus further includes an advancing apparatus having a first arm with a first engaging feature for engaging the handle of the dilation member; a second arm with a second engaging feature for engaging the handle of the expansion member; and an operation member; the first arm and the second arm being connected so that operation of the operation member approximates the first engaging feature and the second engaging feature together.Type: ApplicationFiled: January 16, 2009Publication date: May 21, 2009Inventors: Csaba Rethy, Thomas Wenchell, Kourosh Azarbarzin

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
