ABSTRACT:
System for artificial vessel embolization comprising a catheter adapted to be inserted into the vessel and having a passage extending therethrough. A balloon delivery catheter is slidably mounted in the passage in the first named catheter. The balloon delivery catheter comprises a flexible elongate element having proximal and distal extremities. A detachable balloon is detachably secured to the distal extremity of the flexible elongate element. An adapter is carried by the proximal extremity of the flexible elongate element permitting inflation and deflation of the detachable balloon. The detachable ballon includes a cylindrical valve base having a bore extending therethrough and a self-sealing valve mounted on the valve base. The detachable balloon is mounted by a friction interference fit between the valve base and the distal extremity of the flexible elongate member. The size of the bore of the valve base is selected to provide the desired detachment force for the detachable balloon.
