US Patent:

20100331621, Dec 30, 2010

Filed:

Jun 30, 2009

Appl. No.:

12/458064

Inventors:

Lawrence J. St. George - Sudbury MA, US
John S. Duran - Brewer ME, US
Richard P. Mansfield - Athol MA, US

Assignee:

GYRUS ACMI, INC. - Southborough MA

International Classification:

A61B 1/307

US Classification:

600105

Abstract:

An improved bipolar resection device provides an intuitive finger grip control in a smaller sheath package. Bipolar electrode wires occupy less space by extending in a closely abutting relationship along the sheath and exiting in a one above the other orientation that provides a reduced profile, allowing for better visualization during resection. In various embodiments, resection motion is provided through a rotational sweep transverse to the longitudinal axis of the resection device and may include push/pull motion. The sheath may be oval in shape and the bipolar electrode connected to the bipolar electrode wires having a narrow cross-section to improve resection site visualization.

Assignee:

Smith & Nephew, Inc. - Andover MA

International Classification:

A61B 1704

US Classification:

606139

Abstract:

A suture-passing forceps includes a suturing assembly having a member supported at a distal end of a support shaft, the member having a passage transverse to its length for supporting a suture needle in a suturing position at a selected angular orientation relative to the length of the member and configured to support the suture needle in a stowed position at an angle less than the selected angle of the suture needle in the suturing position.
