Devices and Method for Blood Vessel Occlusion

An occlusion assembly for occluding the aorta of a patient, comprising:

• a balloon envelope, the balloon envelope constructed from an elastomeric material, the balloon envelope defining an interior and an exterior, the balloon envelope having a longitudinal length extending between a proximal end and a distal end of the balloon envelope;
• and
• an elongate shaft, the elongate shaft having a proximal shaft end, a distal shaft end, and a shaft length extending therebetween, the elongate shaft comprising:
• a wire, a proximal shaft region of a first material, a distal shaft region of a second material, and a balloon mounting region extending between the proximal shaft region and the distal shaft region,
• the wire extending the length of the elongate shaft with portions of the wire extending through the proximal shaft region, the balloon mounting region and the distal shaft region,
• the proximal shaft region defining an inflation lumen that extends from the proximal shaft end to the balloon mounting region, the portion of the wire extending through the proximal shaft region is positioned within the inflation lumen, the portion of the wire extending through the distal shaft region is adheringly engaged to the distal shaft region,
• the balloon mounting region having a length greater than the length of the balloon envelope in the molded state, the length of the balloon mounting region extending from a proximal bonding region located on a distal end of the proximal shaft region to a distal bonding region located on a proximal end of the distal shaft region;
• the proximal end of the balloon envelope is bonded to the proximal bonding region and the distal end of the balloon envelope is bonded to the distal bonding region,
• the balloon envelope bonded to the elongate shaft has a longitudinally stretched state, wherein the length of the balloon envelope corresponds to the length of the balloon mounting region,
• the interior of the balloon envelope is in fluid communication with the inflation lumen.
