Abstract:
1. 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; a valve seat defined by and between the proximal end portion of the proximal fitting and the proximal cap; 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 having transverse surfaces adjacent to and engageable with associated surfaces of each of the valve members, 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.
