Publication number: 20060191975Abstract: Describeed is a full-thickness resection system which includes a control unit coupled to a proximal end of a flexible endoscope. The control unit remains outside of a body when the stapling head is in an operative position within a body lumen. The control unit includes (i) an anvil actuator coupled to an anvil in the stapling head, actuation of the anvil actuator moves the anvil axially relative to a stapling mechanism in the stapling head to compress a folded full-thickness portion of lumenal tissue between the anvil and the stapling mechanism. In addition, the control unit includes (ii) a stapler actuator coupled to the stapling mechanism in the stapling head, actuation of the stapler actuator causing the stapling mechanism to drive staples through the folded lumenal tissue against the anvil.Type: ApplicationFiled: April 25, 2006Publication date: August 31, 2006Inventors: Ronald Adams, Roy Sullivan, George Nunez, Lauren Main, Peter Kratsch, Jurgen Kortenbach, Matt Solar, Gerhard Buess, Marc Schurr

Publication number: 20050256562Abstract: A delivery handle and assembly are provided which allow for deployment and reconstrainment of a stent. The delivery assembly may include a catheter having a lumen extending therethrough; and, a housing having an aperture, the catheter extending through the aperture. A driver is movably coupled to the housing such that the driver can selectively move in different first and second directions relative to the housing. The driver is disposed to engage the catheter such that movement of the driver in the first direction causes a distal end of the catheter to move distally, and that movement of the driver in the second direction causes the distal end of the catheter to move proximally.Type: ApplicationFiled: May 10, 2005Publication date: November 17, 2005Inventors: Claude Clerc, Roy Sullivan, John Golden, Gary Jordan
