Patent ID: 7220243

Claim:
A gas inflation/evacuation system and sealing system removably connectable to a proximal portion of a guidewire assembly having a guidewire that defines a lumen, comprising: a. the gas inflation/evacuation system and sealing system adapted to removably attach to a guidewire assembly having (1) a guidewire with a lumen along the length thereof; (2) an occlusion balloon in fluid communication with the lumen which thereby can be inflated and deflated via the lumen; (3) the guidewire having a crimpable portion which is permanently deformable to occlude the lumen thereby maintaining the balloon in an inflated state; b. the gas inflation/evacuation system and sealing system adapted to removably attach to a crimping mechanism having (1) pinch points adapted to crimp the guidewire to permanently deform the guidewire to occlude the lumen thereby maintaining the balloon in an inflated state after removal of the crimping mechanism; c. a first syringe system for selectively evacuating the lumen; d. a second syringe system for selectively introducing a biocompatible gas into the lumen to inflate the occlusion balloon that is in fluid communication with the lumen and that is located proximate a distal end of the guidewire assembly; e. a compression sealing mechanism removably connectable to the proximal portion of the guidewire that comprises: (1) a resilient seal for receiving and sealing around the proximal portion of the guidewire; (2) a compressing apparatus for compressing the resilient seal, the compressing apparatus comprising a sealing cap and a sealing gland, the sealing cap having threads and the sealing gland having threads to engage the threads of the sealing cap; and, f. wherein the compression sealing mechanism is adapted to seal around the proximal portion of the guidewire while the crimping mechanism is used to permanently deform the guidewire to occlude the lumen thereby maintaining the balloon in an inflated state.
