A seal for a hemostasis valve is provided as well as a novel seal stack for use in hemostasis valves. The seal stack includes a plurality of conical or frustoconical members including an anti-prolapse member, and a sealing member. The seal stack may optionally include a diaphragm and/or a second sealing member. The valve body may include a pressure sensing member which may be located in a sidearm.

Hemostasis valve seal

A novel seal is provided along with a valve for implementing the seal in the form of a hemostatic catheterization valve. A pressure-sensing form of the hemostatic valve is also provided. The novel seal includes a pair of cooperating conical gaskets divided through their apexes into a plurality of edge-abutting semi-conical flaps. The seals are angularly fixed in orientation relative to each other using registering structures such as complementary tabs and sockets. More specifically, the seams where the semi-conical flaps abut are angularly off-set between the two conical gaskets by a predetermined amount.

Pressure-sensing bleed-back control valve with improved sealing

A hemostasis or bleed-back control valve such as a Tuohy-Borst adapter is provided that is capable of sensing pressure in vivo. The valve may include a main valve body having a lumen. An upstream main seal may be disposed in the lumen of the main valve body. A catheter fitting may be disposed at a downstream end of the main valve body. A pressure transducer may be in fluid communication with the lumen of the main valve body. Such devices may be suitable for exploratory or interventional medicine involving catheterization.
