Filed:

Nov 3, 2000

Appl. No.:

09/706471

Inventors:

Gregory E. Sancoff - North Hampton NH
Frederic P. Field - North Hampton NH

Assignee:

Onux Medical, Inc. - Hampton NH

International Classification:

A61B 1704

US Classification:

606213, 606144

Abstract:

Apparatus for approximating and closing the walls of a hole or puncture in a physiological shell structure which, in one preferred form, comprises a pair of components that manipulate wire suture. The first component, sometimes referred to herein as a suture introducer, locates the edges of the hole and passes wire suture through them. The second component, sometimes referred to herein as a suture tensioner, gathers the free ends of the wire suture and twists them together, which in turn closes the hole. After the wire suture has been twisted sufficiently to effect closure, the excess wire is trimmed away. The apparatus can deploy more than one wire suture at a time if desired. Using self-locating features and tactile feedback, the apparatus is particularly well adapted to access remote surgical sites.

International Classification:

A61B 1704

US Classification:

606148

Abstract:

A device is disclosed for introducing a flexible elongated element through at least two portions of a subject. In a preferred embodiment, the device includes a proximal end and a distal end, and an advancement unit for longitudinally advancing the flexible elongated element toward the distal end of the device such that a proximal end of the elongated element may exit from the distal end of the device with sufficient force to pass through the subject. The device also includes a curved die at the distal end of the device for imparting a looping configuration to portions of the flexible elongated element exiting the distal end of the device, and a curved guide at the distal end for receiving the looped flexible elongated element as it returns to the distal end of the device. In a further feature of the invention, a cutting mechanism is provided to permit the looped flexible elongated element. to be separated from the remainder of the flexible elongated element.

International Classification:

A61B 1708

US Classification:

606153

Abstract:

An apparatus for placing multiple sutures during anastomosis of physiological vessels includes a crown portion having a plurality of strands connected together by one or more circular bands. The strands each form a point at one end with a curved hook at the same end. The curved hook acts as a suture to retain one or more of the vessels. An alternative embodiment includes a plurality of strands, or wires, that are inserted through one or more vessels to simultaneously place multiple sutures. The present invention also comprises a method for placing a plurality of sutures simultaneously with an apparatus.
