Embodiment Construction

[0041]Surgery often involves joining of two or more layers of tissue together with optional simultaneous sectioning of a portion of the tissue along the staple line. For example, colorectal surgery in many cases involves the resection of a segment of the colon and rectum. Following a colorectal resection, the colon and rectum are drawn together with a circular stapler and an end-to-end anastomosis is performed. Post-op leakage of the anastomosis has been shown to lead to morbidity and mortality.

[0042]Typical surgical stapling instruments have a staple-containing component and an opposing anvil component, between which at least two tissue layers to be joined are compressed prior to delivery of staples from the staple-containing component, whereby staples are piercing both tissue layers and are bent, deformed, or closed against the opposing anvil component.

[0043]Referring now to FIG. 1, a generic surgical anastomosis stapling instrument or stapling device for performing a circular ana...

Abstract

The present invention relates to surgical instruments and methods for enhancing properties of tissue repaired or joined by surgical staples and, more particularly to surgical instruments and methods designed to enhance the properties of repaired or adjoined tissue at a target surgical site, especially when sealing an anastomosis between adjacent intestinal sections so as to improve tissue viability, prevent tissue infection, and to prevent leakage.

Description

FIELD OF THE INVENTION[0001]The present invention relates to surgical instruments and methods for enhancing properties of tissue repaired or joined by surgical staples and, more particularly to surgical instruments and methods designed to reinforce the repaired or adjoined tissue at a target surgical site.BACKGROUND OF THE INVENTION[0002]Throughout the years the medical field has utilized various techniques in an effort to join or bond body tissue together. Historically, suturing was the accepted technique for rejoining severed tissues and closing wounds. Suturing is achieved with a surgical needle and a suturing thread, with the intended function of sutures to hold the edges of a wound or tissue against one another during the healing process. Staples are used to replace suturing when joining or anastomosing various body structures, such as, for example, the bowel. The surgical stapling devices employed to apply staples are generally designed to simultaneously cut and seal an extend...
