Abstract
Retroperfusion catheter comprising a flexible elongate element having proximal and distal extremities and having at least first and second lumens extending therethrough. A flexible tip is secured to the distal extremity of the flexible elongate element. A balloon having proximal and distal portions is secured to the distal extremity of the flexible elongate element. The distal extremity of the balloon overlies a portion of the flexible tip and secures the flexible tip to the distal extremity of the flexible elongate member to ensure that the flexible tip will not become separated from the distal extremity of the flexible elongate element. The flexible elongate element and the flexible tip can be formed as a single member of the same material but of dirrerent hardnesses. Also the flexible elongate element can be formed with an intermediate portion formed of material having a hardness between the different hardnesses.
