Publication number: 20040059346Abstract: A full-thickness resection system is disclosed. In an embodiment for the resection system, the system may include a flexible shaft, a flexible guide member disposed within the flexible shaft, a stapling mechanism disposed around the flexible guide member, and a grasper. The stapling mechanism has an elongated portion that is at least partially disposed within the flexible shaft. The stapling mechanism includes a stapling arm and an anvil arm. The stapling arm has a longitudinal axis and includes a stapling head having a longitudinal axis. The anvil includes an anvil head. The stapling arm and anvil arm extend from the elongated portion of the stapling mechanism and are moveable with respect to each other between a tissue receiving position and a stapling position. The grasper extends through the flexible shaft and is adapted to grasp a portion of a tissue that is to be excised from an organ in the patient's body.Type: ApplicationFiled: January 17, 2003Publication date: March 25, 2004Inventors: Ronald D.

Patent number: 6695198Abstract: The present invention is directed to a full-thickness resection system comprising a flexible endoscope and a stapling mechanism, wherein the endoscope is slidably received through at least a portion of the stapling mechanism. The stapling mechanism includes an anvil and a stapling head mounted to the anvil so that the anvil and the stapling head are moveable with respect to one another. A position adjusting mechanism is provided for moving the anvil and the stapling head relative to one another. An integrated surgical retainer for use in the full thickness resectioning device is described. The integrated surgical staple retainer comprises a calibrating portion, a retaining portion, and a grasping portion. The calibrating portion defines a circular opening which has a diameter substantially equal to a diameter of a working channel of the full thickness resectioning device.Type: GrantFiled: February 21, 2003Date of Patent: February 24, 2004Assignee: SciMed Life Systems, Inc.Inventors: Ronald D.

Patent number: 6695822Abstract: A method and related device for performing sterile medical procedures are disclosed. The method and related device are capable of accessing a sterile environment from a non-sterile environment to perform a medical procedure within the sterile environment. The method and related device can achieve a sterile technique during endoluminal procedures and in uncontrolled and unsterile environments. The device includes an inner hollow member moveably disposed within an outer hollow member. The outer hollow member is adapted to penetrate a boundary separating non-sterile and sterile environments and the inner hollow member is adapted to extend past the outer hollow member and into the sterile environment. A fluid compartment is adapted to be in selective fluid communication with the outer tube such that when the inner member extends past the outer member and into the sterile environment, fluid enters the outer member and the boundary.Type: GrantFiled: October 23, 2002Date of Patent: February 24, 2004Assignee: SciMed Life Systems, Inc.Inventors: Ronald D.

Patent number: 6669706Abstract: A soft and pliable surgical support mesh exhibiting increased resistance to inhabitation of infectious matter. The mesh includes a support trellis formed of multifilament yarns wherein the interstitial voids located between the filaments of said yarns are enclosed within an infection-impervious matrix. The meshes may be designed to be extremely thin yet retain the requisite strength for repairing soft tissue, which allows for a low profile when folded for delivery.Type: GrantFiled: December 18, 2001Date of Patent: December 30, 2003Assignee: SciMed Life Systems, Inc.Inventors: Peter J.

Patent number: 6638292Abstract: Guidewire-deliverable devices and methods of using the devices for separating adjacent layers of tissue and for delivering a surgical prosthesis to an operating site. A guidewire-delverable cannula provides an elongate window for accessing the operating site with a tissue-separating device. The tissue-separating device may include one of several types of an inflatable balloon or a tissue-dissecting member. The tissue-separating balloon may simultaneously deliver the prosthesis during tissue separation and may further be detached to remain with the prosthesis over the operating site. Alternatively, the prosthesis may be separately provided after the adjacent layers of tissue have been separated.Type: GrantFiled: April 2, 2001Date of Patent: October 28, 2003Assignee: Boston Scientific CorporationInventor: Ronald D.

Publication number: 20030192937Abstract: The FTRD described comprises a removable cartridge body that contains a new load of staples and a new blade for use in the FTRD. The cartridge body can be removed and replaced with a new one once the staples have been used. Rotation of a main shaft by the physician causes the staples to be fired and the blade to be moved along a pre determined path to cut the stapled tissue. Tactile and audible feedback is given to the physician when the stapling phase is complete and the cutting phase is to begin.Type: ApplicationFiled: June 5, 2003Publication date: October 16, 2003Inventors: Roy H.
