Abstract
A needle for everting body tissue is a linear member having a back portion, an arcuate tissue penetrating portion, and a generally U-shaped tissue everting portion therebetween. The U-shaped tissue everting portion includes a base and first and second tissue abutment arms, the back portion preferably being collinear with the first arm and oriented at an angle with respect to the base. The needle can be incorporated into an instrument for use in endoscopic procedures. In such instruments the needle can be attached in a fixed position with respect to the instrument, or retractable within a tubular sleeve.
