Abstract
A tubular guidewire assembly having a distal occlusive device and an extended crimpable section proximate a proximal end that is adapted to connect to a gas inflation/evacuation system. The extended crimpable section can be selectively sealed at one of a plurality of separate locations to form an airtight seal of the tubular guidewire assembly. Each time a deflation of the occlusive device is desired in order to reestablish blood flow to a vessel downstream of the occlusive device, the extended crimpable section preferably is cut distal to the location of the last seal to quickly deflate the occlusive device.
