摘要： An adjustable surgical valve has a sealing body (106) with an axial passage extending through it, a toroidal body (111) axially aligned with the sealing body, and a device (110, 120) that selectively changes the relative axial positions of the sealing body and the toroidal body. The sealing body and the toroidal body have mating surfaces which radially compress the axial passage of the sealing body when the relative axial positions of the sealing body and the toroidal body are changed. This causes the axial passage to seal with an instrument (c) inserted into it, or to seal with itself if no instrument is inserted. Alternatively, or additionally, the sealing body may include a braided sleeve (138) coaxial with the axial passage and extending 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 to elongate the braided sleeve. This causes the braided sleeve to contract radially, which compresses the axial passage of the sealing body radially. The sealing body is made of an elastomeric foam or an encapsulated gel. 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, and the braided sleeve, toroidal body, and sealing body are inserted into the bore of a substantially cylindrical valve body.
