Abstract

A percutaneous release mechanism (57) for use with an intravascular treatment device (11) in an intravascular treatment system (10). The release mechanism includes an inner member (17) having a connection mechanism (18) positioned about the distal end (14) thereof for interconnection with another connection mechanism (12) positioned on an intravascular treatment device. The release mechanism also includes an outer member tube (13) of which the inner member is positioned therein. The first and second connection mechanisms are interconnectable and positionable in the passage (16) of the tube for delivering the treatment device in a delivery state to the treatment site. The release mechanism also includes a handle (37) having parts (38, 39) connected to the inner member and outer tube, whereby movement of the proximal end of the inner member is translated to the distal end thereof for extending the interconnected connection mechanisms from the passage of the outer member tube and positioning the treatment device in a treatment state. The intravascular treatment system includes the percutaneous release mechanism along with the intravascular treatment device. The treatment device includes an occlusion coil (23) and a rigid tube (36) connected to the flexible outer member tube (35) for maintaining the delivery coil in a delivery state. In another example, the treatment device includes a blood clot filter (40) in which the percutaneous delivery mechanism is adapted for connection thereto.
