Benefits of technology

The patent text describes improved methods and devices for performing a totally transoral surgical procedure, such as a posterior gastropexy procedure, without the need for more-invasive laparoscopic procedures. The invention provides a single mechanism for automatically locking and cutting a suture, simplifying medical procedures. The suture lock assembly and lock actuating device are small enough to pass through the working channel of various endoscopic and ultrasound devices. The invention can be used with various types of suture and is suitable for various medical procedures.

Problems solved by technology

Such procedures are invasive, as laparoscopy requires that small access incision(s) be made in the body of the patient, through which a laparoscope and other surgical enabling tools are provided, while open surgical techniques are traditionally invasive and can have complications and cause long patient recovery periods.
This may result in multiple passes of instrumentation back and forth through the working channel of the endoscope.
Additionally, the locking mechanism described in the publication is too large to pass through the working channel of an endoscope and, thus, it must be inserted into the patient separately from the endoscope, which again adds complexity to the medical procedure.

first embodiment

[0027]FIG. 1A illustrates a perspective view of a suture lock assembly 100 in accordance with the invention. Suture lock assembly 100 includes an extension spring 112 arranged between a distal endcap 114 and a proximal endcap 116.

[0028] Extension spring 112 is formed of any nontoxic, noncorrosive metal, such as stainless steel, and distal endcap 114 and proximal endcap 116 are formed of, for example, molded plastic or stainless steel. Also shown in FIG. 1 is a suture 118 threaded first through a hole 120 in distal endcap 114 and then through multiple coils of extension spring 112, wherein suture 118 is clamped because of the pressure of the coils and the tortuous path within the coils. Suture lock assembly 100 is not limited to a single suture 118 installed therein; a plurality of sutures 118 may be engaged within a single suture lock assembly 100.

[0029]FIG. 1B illustrates a cross-sectional view of suture lock assembly 100 taken along line AA of FIG. 1A. This view shows that proxim...

second embodiment

[0057]FIG. 8 illustrates a perspective view of a suture lock assembly 800 in accordance with the invention. Suture lock assembly 800 includes a cylindrical-shaped lock body 810 that further includes a plurality of suture channels 812 that run therethrough, and which have an associated plurality of locking holes 814 arranged on the outer surface of lock body 810. Suture lock assembly 800 further includes a lock sleeve 816 that further includes a cavity 818 (shown in FIGS. 9 and 10) within which lock body 810 is inserted. Lock body 810 further includes a first groove 824 and a second groove 826, which are detents formed around the outer perimeter of lock body 810. Lock sleeve 816 further includes a first locking ring 820 and a second locking ring 822, which are raised regions protruding from the inside perimeter of cavity 818 that are sized to lock within the detents formed by first groove 824 and second groove 826 of lock body 810.

[0058] Also shown in FIG. 8 is suture 118, which is a...

Abstract

Suture holding devices and methods are disclosed, including devices and methods useful in performing a transoral surgical procedure, such as a posterior gastropexy procedure. A device is disclosed which can be used by a physician in a medical procedure to automatically lock and cut a suture in one motion and without the need for additional cutting instrumentation, rather than perform separate locking and cutting actions.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims priority to and incorporates by reference the following applications: U.S. Provisional Application 60 / 571,117 filed May 14, 2004; U.S. provisional Application 60 / 571,119 filed May 14, 2004; and U.S. Provisional Application 60 / 571,000 filed May 14, 2004.FIELD OF THE INVENTION [0002] This invention relates to endoscopic suturing devices and methods, including devices and methods which may pass through or be employed in connection with the working channel of various endoscopic and ultrasound devices. BACKGROUND [0003] Application of sutures in the gastrointestinal tract is required for several different types of medical procedures, for example, for transoral endoscopic valvuloplasty for gastroesophageal reflux disease (GERD), gastroplasty, fundoplication, anterior gastropexy, posterior gastropexy, suturing esophageal perforations, or closure of the esophageal side of the tracheo-esophageal fistula. Traditionally, th...
