US Classification:

606 50, 606 48, 606 51, 606170, 606171

Abstract:

A surgical device including: a first shaft having a first projection radially offset from an axial direction of the first shaft, the first projection having a first clamping surface; a second shaft slidably disposed relative to the first shaft, the second shaft having a second projection radially offset from the axial direction, the second projection having a second clamping surface; a dissector for dissecting tissue from a blood vessel to be harvested; a first actuator for sliding the second projection relative to the first projection to capture a side branch of the vessel between the first and second clamping surfaces; at least one electrode for applying cauterizing energy to cauterize the captured side branch; a cutting blade movably disposed on one of the first or second projections; and a second actuator for moving the cutting blade to sever the side branch captured between the first and second projections.

Assignee:

Ethicon, Inc. - Somervillle NJ

International Classification:

A61B 1732

US Classification:

606 50, 606 48, 606 45, 606 51

Abstract:

A surgical device for severing tissue, the surgical device comprising; a first shaft having a first internal lumen and a first slot disposed at a distal end; a clamp slidingly disposed in the first slot between open and closed positions to capture tissue in the first slot, the clamp having a clamping surface disposed at a distal end; at least one electrode for applying RF energy to the tissue captured in the first slot; a cutting blade slidingly disposed in the first slot between open and closed positions, the cutting blade having a cutting edge to sever the tissue; first actuation means for actuating the clamp between the open and closed positions; and second actuation means for actuating the cutting blade between the open and closed positions.

Aug 28, 2001

Appl. No.:

09/941008

Inventors:

Kevin S. Weadock - Belle Mead NJ

Assignee:

Ethicon, Inc. - Somerville NJ

International Classification:

A61D 100

US Classification:

606219, 606153

Abstract:

An anastomosis staple comprising of a plurality of vessel engaging members and a binding structure holding the vessel engaging members together is described. The binding structure has at least one bioabsorbable element. The binding structure is rigid enough to allow for deployment and quickly resorbs to avoid problems associated with intimal hyperplasia and physical hindrance of secondary interventional procedures. The vessel engaging members may be comprised of superelastic or shape memory metal and are independent from one another. The members may be equidistant from one another and embedded within the binding structure. The composite staple can preferably serve as a drug delivery vehicle.

Assignee:

Ethicon, Inc. - Somerville NJ

International Classification:

A61F 0206

US Classification:

623 114, 623 136

Abstract:

An prosthesis for the repair of thoractic or abdominal aortic aneurysms (AAA) and a method for utilizing the prosthesis. Furthermore, an arrangement and method is provided for the repair of aortic aneurysms incorporating a device for the placement of the prosthesis in the corporeal lumen or body vessel of a patient, and wherein the prosthesis comprises a graft facilitating the exclusion of the aneurysm, and also provides for anastomotic structure for the attachment of the prosthesis in a laparoscopic surgical procedure.

Assignee:

Ethicon, Inc. - Somerville NJ

International Classification:

A61M 3100

US Classification:

604507, 604509, 60410308

Abstract:

The present invention provides a mechanism by which the physical properties of diseased blood vessel walls can be manipulated to achieve an effective vessel lumen diameter for a prolonged period of time. The methods and devices of the present invention selectively isolate and treat the medial or adventitial layers of these diseased blood vessels. The invention is based on the delivery of proteolytic enzymes and crosslinking agents via specialized delivery devices to a select layer of the diseased blood vessel wall. By isolating and treating these layers of the artery, collagen degrading and collagen crosslinking agents can be delivered so as to affect the diameter of the blood vessels and control blood flow therein.

Assignee:

Ethicon, Inc. - Somerville NJ

International Classification:

A61B 1000

US Classification:

600562, 606 1

Abstract:

A medical specimen carrier, and a method for using the same, is provided wherein the specimen carrier includes a housing having a plurality of compartments therein each capable of holding a tissue specimen. The housing has a length and a cross-section smaller than a cross-section of a surgical port so as to enable it to pass therethrough, and is dimensioned to be placed within the surgical site separate from the surgical port or other surgical instrument. The medical specimen carrier further includes a cover device capable of selectively opening and closing each of the plurality of compartments.
