Abstract
An over-the-needle catheter for insertion into an anatomical passage through the use of an introducer. The catheter comprises an elongate, flexible catheter body defining proximal and distal ends, and a lumen extending longitudinally therethrough. Partially inserted into and protruding from the distal end of the catheter body is a rigid, tubular sleeve which defines an abutment shoulder within the lumen of the catheter body. Disposed on and encapsulating the exposed portion of the sleeve is a distal tip member defining a central opening which communicates with the lumen via the sleeve. The abutment shoulder is adapted to abut a portion of the introducer in a manner which inhibits proximal movement of the tip member relative to the introducer to prevent the tip member from being pushed proximally over the introducer and collapsing the catheter body during the insertion of the catheter into the anatomical passage.
