Hemostatic valve and splittable introducer

摘要

In at least one embodiment, a hemostatic valve for use with a splittable introducer (10) is provided. The hemostatic valve (22) comprises a seal (24) molded in a first configuration of polymeric material and having two adjacent end surfaces (34,35). The seal is deformable from the first configuration into a second configuration. In the first configuration, the seal is substantially non-planer with the two adjacent end surfaces exposed. In the second configuration, the two adjacent end surfaces are unexposed so as to form a split extending through the seal.

1. A hemostatic valve for use with a splittable introducer, the hemostatic valve comprising:
a seal formed as a single piece and molded in a first configuration of polymeric material and having two adjacent end surfaces, the seal being deformable from the first configuration into a second configuration, the seal in the first configuration is substantially non-planar with the two adjacent end surfaces exposed and the seal in the second configuration includes the two adjacent end surfaces being unexposed so as to form a split extending through the seal; wherein the seal in the second configuration has a diaphragm form with an outer perimeter portion, the diaphragm form defining a plane extending therethrough and a central axis positioned at the center of the diaphragm form normal to the plane; wherein the seal in the second configuration has a center hole extending along the central axis and a spiral lip disposed about the central axis covering the center hole, the spiral lip and the hole cooperatively configured to facilitate receiving the medical device; and wherein one of the two adjacent end surfaces defines a positive feature and the other of the two adjacent end surfaces defines a negative feature that receives the positive feature when the seal is in the second configuration to enhance sealing of the hemostatic valve.
