摘要：A medical device for creating images of tissue within a body includes adisposable liquid-confining sheath supporting an elongate flexible drive shaft whichcarries an imaging device such as a ultrasound transducer. The device may include a trocaradapted to receive the sheath, the trocar permitting the device to be inserted into the

body where no natural passageway exists, the trocar having a side-facing region adaptedto maintain registry with the imaging device while the imaging device rotates. In anotherembodiment, the drive shaft includes an outer coil that is configured such that when thedrive shaft is driven in the direction tending to decrease the diameter of the outer coil,the outer surface of the outer coil pressurizes liquid distally of the outer surface. Thedevice optionally includes an inflatable balloon.
