Abstract
Abstract An ultrasound imaging sheath for invasive imaging, in particular for imaging blood vessels including the coronary vessels. The sheath is comprised of three lumens; one serves as an ultrasound probe passage, one serves as a guide wire passage, and one serves as either a probe or a guide wire passage and is connected to the other two. Methods of using the sheath disclosed to obtain ultrasound images of a region within a subject are also disclosed.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
95 words
An ultrasound imaging sheath comprising: a flexible distal tip portion with a tip lumen adapted to accept a guide wire; a flexible dual lumen region comprising a guide wire lumen adapted to accept a guide wire, and a probe lumen adapted to accept an ultrasound probe; and a flexible intermediate section comprising an intermediate lumen communicating at a proximal end with both the wire lumen and the probe lumen, and communicating at a distal end with the tip lumen, wherein the intermediate lumen is adapted to alternately accept the guide wire and the ultrasound probe.
Claim 2
Dependent Claim

An ultrasound imaging sheath comprising: a flexible distal tip portion with a tip lumen adapted to accept a guide wire; a flexible dual lumen region comprising a guide wire lumen adapted to accept a guide wire, and a probe lumen adapted to accept an ultrasound probe; and a flexible intermediate section comprising an intermediate lumen communicating at a proximal end with both the wire lumen and the probe lumen, and communicating at a distal end with the tip lumen, wherein the intermediate lumen is adapted to alternately accept the guide wire and the ultrasound probe.
Claim 3
Dependent Claim
34 words
A sheath as in claim 1 further comprising a lubricating surface coating disposed on an inner wall of one of; the tip lumen, the intermediate lumen, the guide wire lumen and the probe lumen.
Claim 4
Dependent Claim
22 words
A sheath as in claim 1 wherein the tip lumen comprises a tapered section and a radio opaque marker for X-ray viewing.
Claim 5
Dependent Claim
20 words
A sheath as in claim 1 further comprising a radio opaque marker for X-ray viewing disposed within the intermediate section.
Claim 6
Dependent Claim
