US 10,299,786 B2 · Surgical suturing device with transverse engagement

Abstract

A minimally invasive suture insertion device utilizing small gage needles is provided for threading one or more sutures through subcutaneous tissue, both locally and from remote access points, to support, attach, sever, ligate or constrict tissue, vessels, ligaments, nerves or other anatomical features, or for pulling another device into position defined by a suture pathway. A manually operated suture transfer device and method are provided for use in various surgical applications. The suture transfer device operates as an instrument for inserting sutures into and through desired pathways. Tethered cannulas are coupled to the positioned sutures and dock, transversely, with a captured component having a capacity for engaging a single suture or multiple sutures, together or in turn within subcutaneous tissue from local or remote access points.

Dependent claims

An engagement tool for subcutaneously capturing a surgical suture or thread using a percutaneous procedure, the engagement tool comprising:

a handle having a proximal end and a distal end;
an outer cannula defining a longitudinal axis, the outer cannula extending from the distal end of the handle and having a base end and a tip;
an engagement feature including a width portion and a height portion, the width portion defining a width along the longitudinal axis, the height portion defining a height perpendicular to the longitudinal axis, the width and height defining an opening being greater than a diameter of the suture or thread;
and
a capture mechanism movable subcutaneously between a position exposing the opening of the engagement feature, such that the suture or thread can be received by the engagement feature when the engagement feature is in transverse tangential alignment to the suture or thread, and a position closing the opening of the engagement feature, thereby capturing the suture or thread within the engagement feature, the capture mechanism being retained within the outer cannula during initial capture of the suture or thread and subsequent release of the suture or thread.

a suture or thread retaining first member and a first suture or thread extending therefrom;
and
an engagement tool,
the engagement tool comprising:
a handle having a proximal end and a distal end;
an outer cannula defining a longitudinal axis, the outer cannula extending from the distal end of the handle and having a base end and a tip;
an engagement feature including a width portion and a height portion, the width portion defining a width along the longitudinal axis, the height portion defining a height perpendicular to the longitudinal axis, the width and height defining an opening being greater than a diameter of the suture or thread;
and
a capture mechanism movable subcutaneously between a position exposing the opening of the engagement feature, such that the suture or thread can be received by the engagement feature when the engagement feature is in transverse tangential alignment to the suture or thread, and a position closing the opening of the engagement feature, thereby capturing the suture or thread within the engagement feature, the capture mechanism being retained within the outer cannula during initial capture of the suture or thread and subsequent release of the suture or thread.
