Surgical suturing instrument and method of use

Abstract

A device is disclosed for introducing a flexible elongated element through at least two portions of a subject. In an embodiment, the device includes a proximal end and a distal end, as well as an advancement unit for longitudinally advancing the flexible elongated element toward the distal end such that a proximal end of the elongated element may pass from the distal end of said device with sufficient force to pass through the portions of the subject. The device also includes a securing unit for variably adjusting a securing force applied by the flexible elongated element to secure together the portions of the subject.

Description

REFERENCE TO EARLIER APPLICATIONS[0001] The present application claims the benefit of pending prior U.S. Provisional Patent Application Serial No. 60 / 098,152, filed Aug. 27, 1998 by Gregory E. Sancoff et al. for MEDICAL SUTURE INSTRUMENT, and pending prior U.S. Provisional Patent Application Serial No. 60 / 118,039, filed Feb. 1, 1999 by Gregory E. Sancoff et al. for ENDOSCOPIC WIRE SUTURING DEVICE.[0002] The two above-identified documents are hereby incorporated herein by reference.FIELD OF THE INVENTION[0003] This invention relates to medical instruments and procedures in general, and more particularly to suturing instruments and methods for suturing.BACKGROUND OF THE INVENTION[0004] Suturing instruments are typically used to draw together two or more portions of a subject patient (e.g., tissue such as muscle or skin) or to attach an object to the patient (e.g., to attach a piece of surgical mesh to the abdominal wall of the patient during hernia repair surgery).[0005] Certain sutur...

Problems solved by technology

This is generally undesirable, since the needle typically leaves a larger hole in the subject than is necessary to accommodate only the suture material.

However, this device does not permit sufficient flexibility with regard to the amount of tension that may be applied to the suture and tissue.

Unfortunately, however, such a system does not permit sufficient flexibility in all situations with regard to the appropriate amount of tension to be applied to the subject, since the wire is relatively firm (i.e., firm enough to hold its sets).

Such a system also does not provide sufficient flexibility with regard to the appropriate type of suture stitch to be applied, since the device is specifically configured to provide onl
