Abstract
The invention is a hemostasis valve having a main body, a proximal end cap, a register member, and a reinforcing member. The main body has a proximal end, a distal end, and a first bore having a proximal end at the proximal end of the main body and a distal end at the distal end of the main body. The first bore has a first flexure-receiving enlargement at its proximal end. The proximal end cap is joined to the proximal end of the main body and forms therewith a valve chamber. The proximal end cap has a second bore formed therethrough that is at least approximately an extension of the first bore. The register member is received in the valve chamber adjacent the proximal end cap. The register member has a proximal portion and a distal portion. The proximal portion of the register member has a third bore formed therethrough that is at least approximately an extension of the first and second bores. The distal portion of the register member is flexible and contains at least one slit on the extension of the first, second, and third bores. The third bore has a second flexure-receiving enlargement adjacent its distal portion. The reinforcing member is received in the valve chamber adjacent the main body, and it has at least one slit on the extension of the first, second, and third bores.
