Abstract:
1. A hemostasis valve for assembly within a medical device, comprising: a valve body having a proximal cylindrical end, a distal end portion and a central passage extending from the proximal end to a distal end, the distal end including a pair of distally extending opposed side walls converging at distal ends forming a distal tip having a virtual opening therethrough, and the valve body further including a pair of tensioners projecting radially outwardly from side sections of the respective distally extending opposed side walls to exterior tensioner faces for engaging an interior wall of a valve housing defined in the medical device within which the valve body is disposed, wherein each tensioner comprises two lateral sidewalls coextending between an outer joint at a common exterior end and an inner joint at the distally extending opposed side walls of the valve body, defining a radially elongate hollow center opening therebetween, whereby the tensioners bear against the interior valve housing wall to press the distally extending side walls toward and against each other at the distal tip to close the virtual opening either completely in a sealing fashion or sealingly against outer surfaces of another medical device inserted through the valve's central passage and virtual opening.
