Abstract:
A device for occluding a vascular segment, comprising:a tubular member having an expandable member at a distal end portion thereof, said tubular member configured for insertion into a blood vessel, said tubular member defining a lumen having at its proximal section a transverse surface at least partially occluding said lumen, said transverse surface having an opening of a first transverse profile;an elogated member within said tubular member and passing through said opening of said tubular member promixal section, said expandable member connected to a distal end portion of said elongate member, said elongate member expanding said expandable member into contact with the blood vessel as said tubular member and said elongate member are moved with respect to each other; anda lock fixed on a proximal portion of said elongate member which engages said transverse surface of said tubular member, without extending radially beyond an outer surface of said tubular member, to prevent movement of said elongate member in at least one direction with respect to said tubular member when said expandable member is expanded to contact the blood vessel;said lock having a second transverse profile which, when said expandable member is expanded, interferes with said first transverse profile of said opening of said tubular member proximal section.
