US Classification:

2271751, 227 19, 2271761, 606139, 606219

Abstract:

The present disclosure describes a surgical fastener applying apparatus that includes an elongate body portion having proximal and distal ends, an end effector including a first movably coupled to a second jaw that is positioned at the distal end of the elongate body portion, and an introducer member. The introducer member has proximal and distal portions, and is configured and dimensioned for releasable connection with the end effector. The introducer member is at least partially formed from a flexible material, and is configured and dimensioned to separate target tissue from collateral tissue prior to positioning of the target tissue between the first and second jaws of the end effector.

Appl. No.:

8/929548

Inventors:

B. Keith Wells - Marietta GA
William R. Mayfield - Atlanta GA
Gregory R. Furnish - Louisville KY

Assignee:

Genzyme Corporation - Framingham MA

International Classification:

A61B 122

US Classification:

600201

Abstract:

A hand-held retractor that is adapted for endoscopic use at a predetermined area of a patient. The retractor is comprised of a longitudinally-extending blade with a proximal end, a distal end, and a top surface. A handle is connected to the proximal end of the blade by a separating member, which is preferably arcuate. The separating member is configured to allow a surgeon direct access to and visualization of the area adjacent the top surface and distal end of the blade after positioning the distal end of the blade at the predetermined area. Also provided is a method of endoscopic retrosternal adhesiolysis which utilizes a retractor to provide access to and visualization of adhesions adjacent the cranial portion of a patient's sternum while retracting away and protecting underlying tissue.
