Surgical fastening system

Abstract

Devices and systems related to surgical fasteners and more specifically to surgical fasteners suitable for use in both open procedures, and minimally or less invasive procedures where the operative site is remote from the surgeon.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] The present invention is a continuation of U.S. patent application Ser. No. 10 / 798,018 filed on Mar. 11, 2004, the entirety of which is incorporated by reference.FIELD OF THE INVENTION [0002] The present invention relates to surgical fasteners and more specifically to surgical fasteners suitable for use in both open procedures, and minimally or less invasive procedures where the operative or surgical site is not directly accessible by the surgeon. BACKGROUND OF THE INVENTION [0003] Surgical fasteners are known to be an alternative to traditional suturing techniques for procedures involving tissue closure, connection, or repair. One undesirable aspect of manual suturing is that the suturing process adds time to the overall surgical process. Moreover, manual suturing often requires that the operative area is readily accessible so that the medical practitioner can manipulate the suture and associated needle through both sides of the tissue...

AI Technical Summary

Benefits of technology

"The present invention is a surgical fastener that can be deployed through a device like a needle or catheter. The fastener comprises an anchor member that can expand from a first state to a second state, where the second state is of a larger size. The fastener can be used in various surgical procedures requiring fastening or repairing tissue. The invention is especially useful for minimally invasive procedures where the operative site is remotely accessed using minimally invasive techniques. The fastener can be easily deployed with accuracy and effectuate a proper seal with the fastener. The invention also provides features that improve the ability of the surgeon to deploy the fastener with accuracy. The application incorporates a patent filed in 2003."

Problems solved by technology

One undesirable aspect of manual suturing is that the suturing process adds time to the overall surgical process.

In addition, suturing techniques requires considerable skill and dexterity especially when tying knots in the suture or otherwise manipulating the suture.

The ability of a medical practitioner to manipulate a suture as well as knot the ends of the suture are further complicated when the site is not directly accessible to the practitioner.

In such cases, even if the complexity of suturing does not prevent the procedure from being completed in a minimally invasive manner, the length of the procedure is likely to increase.

Conventional fasteners do not easily lend themselves for use in minimally invasive surgical procedure.

As one example, the complexity of the known fastener-delivery devices requires devices with large profiles and limited flexibility further thereby limiting the potential for such devices to access remote locations.

Conventional surgical fasteners, especially, “I-shaped” or “H-shaped” fasteners are unsuitable for remote procedures due to their complex deployment mechanisms and inability to navigate tortuous pathways using access devices commonly used for minimally invasive procedures (e.g., catheters, introducer devices, scope-type devices such as endoscopes, bronchoscopes, colonoscopies, etc.).
