Adjustable valve having a radially compressible sealing body

A surgical valve comprising:

• a substantially cylindrical valve body having a bore;
• a sealing body fixed coaxially in the bore of the valve body, the sealing body having an axial passage extending therethrough;
• a toroidal body, axially aligned with the sealing body, slidably mounted in the bore of the valve body, and having an axial position therein, the sealing body and the toroidal body having mating surface means whereby changing the axial position of the toroidal body compresses the axial passage of the sealing body;
• and
• means attached to the toroidal body for selectively changing the axial position of the toroidal body.

A surgical valve comprising:

• a sealing body, the sealing body:
• having an axial passage extending therethrough, the axial passage defining an axis, the sealing body having a position on the axis, and
• including a braided sleeve coaxial with the axial passage, the braided sleeve extending from the sealing body to provide a remote part, the remote part having a position on the axis;
• and
• a position changing means for selectively changing the position of one of the sealing body and the remote part of the braided sleeve relative to the other to elongate the braided sleeve axially, thereby radially compressing the axial passage of the sealing body.
