Patent ID: 8343107

Claim:
A valve subassembly for a vascular guidewire introducer device having a needle for vascular access and a bulb to enable visual verification of vascular access, comprising: a proximal fitting having a distally extending conduit with a conduit passageway therethrough and having a proximal end portion; a proximal cap adapted to be affixed to the proximal end portion of the proximal fitting and having a bore therethrough aligned with the conduit passageway; one of the proximal end portion of the proximal fitting and the proximal cap defining a valve seat; and a valve arrangement insertable within the valve seat, the arrangement having a distal valve member and a proximal valve member and a spacer therebetween, the spacer having an axial bore therethrough and the distal and proximal valve members each having an opening for insertion of a guidewire therethrough, wherein transverse valve-adjacent surfaces of the proximal cap, the proximal fitting and the spacer axially compress the distal and proximal valve members upon assembly.
