Patent ID: 8858504

Claim:
A haemostatic valve assembly including: a valve housing including a first and a second hole: a conformable valve element located within the valve housing and including at least one elongate seal surface defining an internal passage extending in a longitudinal direction between the first and the second hole of the valve housing, the valve element configurable between an open configuration in which the internal passage is open and a sealing configuration in which the internal passage is substantially sealed; a chamber between the housing and the conformable valve element; a resilient element disposed and remaining within the chamber, which biases the conformable valve element towards said sealing configuration; wherein the valve element seals the chamber from the first and the second hole; and wherein the valve element is responsive to the application of a vacuum to the chamber to compress said resilient element so as to attain said open configuration, and in the absence of the application of a vacuum the resilient element causes the internal passage to be substantially sealed.
