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. The present invention further relates to circular stapling instruments and elongated tubular hollow sleeves deployed from such stapling instruments and establishing an enclosure around the stapled and resected tissues at the anastomotic joint.
