ABSTRACT:
In a method of making a surgical valve, a sealing body is attached inside one end of a braided sleeve, the other end of which is threaded through the bore of a toroidal body. The braided sleeve, toroidal body, and sealing body are inserted into the bore of a substantially cylindrical valve body. The sealing body generally has an axial passage extending through it which is axially aligned with the toroidal body. The braided sleeve is also typically coaxial with the axial passage and extends from the sealing body, and a device that selectively changes the relative axial positions of the sealing body and the extended part of the braided sleeve elongates the braided sleeve. This causes the braided sleeve to contract radially, which compresses the axial passage of the sealing body radially.
