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.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
87 words
A method for imaging and treating an occlusion within a selected region of a patient's blood vessel, said method comprising the steps of: generating a first image of said occlusion using an ultrasonic transducer disposed in a distal region of a catheter body; advancing a mechanical working element deployed in said distal region of said catheter body through said selected region of said patient's blood vessel to remove at least a portion of said occlusion; and generating a second image of said occlusion using said ultrasonic transducer.
Claim 2
Independent Claim
87 words
A method for imaging and treating an occlusion within a selected region of a patient's blood vessel, said method comprising the steps of: generating a first image of said occlusion using an ultrasonic transducer disposed in a distal region of a catheter body; advancing a mechanical working element deployed in said distal region of said catheter body through said selected region of said patient's blood vessel to remove at least a portion of said occlusion; and generating a second image of said occlusion using said ultrasonic transducer.
Claim 3
Dependent Claim
35 words
The method of claim 1, wherein said image generating and working element advancing steps are repeated until a predetermined amount of said occlusion has been removed from said selected region of said patient's blood vessel.
Claim 4
Dependent Claim
46 words
The method of claim 1, further comprising the step of stabilizing said working element by inflating a balloon affixed to an exterior surface of said distal region of said catheter body to urge said distal region of said catheter body against an area of occluding tissue.
Claim 5
Dependent Claim
14 words
The method of claim 1, wherein said mechanical working element comprises a rotary element.
Claim 6
Dependent Claim
12 words
The method of claim 4, wherein said rotary element comprises a cutter.
