Title:
PRESSURE RELIEF DEVICES FOR USE WITH BALLOON CATHETERS
Document Type and Number:
WIPO Patent Application WO/2004/060468
Kind Code:
A8
Abstract:
A pressure relief mechanism is incorporated into a modified syringe-type inflation device that may be coupled to a balloon catheter for inflating and deflating the balloon. An engagement mechanism selectively engages and disengages from a threaded shaft for advancing or withdrawing a plunger placed in slidable, yet sealing fit within a cylindrical chamber. In a first engaging position, the threaded shaft may be forcibly advanced or withdrawn in the cylindrical chamber, while in a second disengaged position, the plunger may be quickly pulled back.
