Sheath 50, 100 for an ultrasound probe 52 includes a sheath body 70 and an end cap 76. The sheath body is disposed about the probe 52 with the end cap 76 disposed about the end 57 of the probe 52. A band 78 is disposed about the body 70 in order to define between the end cap 76 and the band 78 a portion of the sheath 50 which can be expanded with fluid pressure in order to properly position the probe in a human cavity. The end cap 76 prevents fluid from expanding the end of the sheath 50. Alternatively a toroidal chamber 118 can be defined by a first cylindrical body 102 of the sheath 100 in combination with a second cylindrical body 116. A conduit 120 is provided externally to the probe 52 and sheath 100 for introducing fluid into the toroidal chamber 118.

A sheath for use with an ultrasound probe which has a front insertion end, a middle section containing an ultrasound transducer and a handle end, the middle section defining a front end located adjacent the front insertion end and a back end located adjacent the handle end, the transducer being located between the front and back ends, and a fluid outlet located adjacent the middle section, said sheath comprising: an elongate cylindrical sheath body having a first end and a second end, and wherein said first end is closed and said sescond end is open and adapted to allow for the reception of an ultrasound probe such that said sheath is adapted to cover at least a front insertion end, the middle section, and a fluid outlet, and to extend toward the handle end of a probe; said sheath body being flexible; said sheath having an integral end cap formed about said first end and extending toward and adapted to end at a position adjacent about a front end of a middle section with a probe inserted into the sheath; said end cap and said first end being substantially less flexible than said sheath body; and means adapted for at least partially conforming said sheath body to a probe at a position adjacent a back end of a middle section for defining a chamber between said end cap and said conforming means in order to accept and retain fluid adjacent a transducer.
