Abstract
Abstract A catheter is provided for insertion into the blood vessel of a patient for ultrasonically imaging the vessel wall. The catheter includes a tubular element and an internally housed drive cable for effective a circumferential scan about the catheter of an ultrasonic generating means. Both the tubular element and the drive cable are of a size and flexibility sufficient to permit their introduction into the vessel and subsequent advancement through the vessel to the location of the vessel wall where imaging is desired.
