Abstract

A catheter introducer having a secondary heomstatic seal formed from a resilient material and having a flange. A downwardly- depending conic section has a orifice in its apex. The cross sectional area of the secondary heomstatic seal decreases between the flange and the orifice. Compressive radial forces on an introduced catheter and, acting collaboratively with a primary hemostatic valve, forms an effective, leak-resistant hemostatic seal around the catheter. This seal better restricts the backflow of fluids, typically blood, around a catheter inserted into a blood vessel through an introducer. In one embodiment a unique upper auxiliary valve is provided to be placed adjacent an existing hemostatic valve in a catheter introducer. The novel configuration of the auxiliary valve and the lower valve provides a vastly improved hemostatic seal that prevents blood loss from leakage around the catheter during procedures such as angiography or other endovascular interventions .
