Abstract
A self-sealing valve device for an angiographic catheter includes a housing having a first end adapted to form a luer lock connection with the proximal end of the angiographic catheter. A central bore extends between the first end of the housing and an opposing second end, and a deformable elastomeric slit seal is supported across the central bore to selectively seal the proximal end of the catheter. The slit seal is adapted to permit a guidewire to be passed therethrough and advanced into the catheter while sealingly engaging the walls of the guidewire to prevent blood loss through the catheter. The second end of the housing is provided with a female luer lock connection fitting for receiving the conical tip of a syringe, stopcock, or the like, and forming a pressure-tight connection therebetween. The insertion of the conical tip of the syringe into the second end of the housing automatically deforms the slit seal for allowing fluid to pass freely therethrough, while again sealing the proximal end of the catheter when the conical tip of the syringe is removed.
