Abstract
A sheath comprising a tubular structure formed of a flexible material which is compatible for insertion within the body and having proximal and distal ends. In one embodiment, the tubular structure includes one slit having an open and a closed end. The tubular structure is further comprised of a tab defined by the slit whereby, when the tab is pulled apart from any object extending through the lumen of the tubular structure, the tubular structure tears longitudinally removing the tubular structure from the object. In another embodiment, the tubular structure is cuffed between the closed end of the slit and the distal end of the tubular structure, the cuff defining the proximal end of the tubular structure. The cuff prevents the slit from tearing prematurely and further provides a blunt, smooth open end at the proximal end that permits closure thereof by thumb pressure only in order to temporarily block blood flow or air aspiration during use.
