Abstract
Abstract The devices disclosed herein are directed to altering gaseous flow within a lung to improve the expiration cycle of, for instance, an individual having Chronic Obstructive Pulmonary Disease. More particularly, these devices produce collateral openings or channels through the airway wall so that oxygen depleted/carbon dioxide rich air is able to pass directly out of the lung tissue to facilitate both the exchange of oxygen ultimately into the blood and/or to decompress hyper-inflated lungs.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
108 words
A medical device for detecting motion within tissue by observing a Doppler shift and for creating channels in tissue, the medical device comprising: a flexible elongate member having a proximal end and a distal end; a transducer assembly adapted to generate a source signal and receive a reflected signal, a portion of said assembly located adjacent to said distal end of said elongate member, said transducer assembly comprising a lens located at said distal end of said transducer assembly, and having a front surface; and at least one heating element where at least a portion of the heating element is disposed on the front surface of the lens.
Claim 2
Dependent Claim
108 words
A medical device for detecting motion within tissue by observing a Doppler shift and for creating channels in tissue, the medical device comprising: a flexible elongate member having a proximal end and a distal end; a transducer assembly adapted to generate a source signal and receive a reflected signal, a portion of said assembly located adjacent to said distal end of said elongate member, said transducer assembly comprising a lens located at said distal end of said transducer assembly, and having a front surface; and at least one heating element where at least a portion of the heating element is disposed on the front surface of the lens.
Claim 3
Dependent Claim
25 words
The medical device of claim 1 , wherein said heating element comprises a plurality of openings allowing for passage of said signals through said openings.
Claim 4
Dependent Claim
16 words
The medical device of claim 2 , wherein said heating element comprises a metallic mesh material.
Claim 5
Dependent Claim
17 words
The medical device of claim 1 , further comprising an energy source coupled to said heating element.
Claim 6
Dependent Claim
27 words
The medical device of claim 4 , wherein said energy source comprises a RF energy source and wherein said heating element comprises at least one RF electrode.
Claim 7
Dependent Claim
17 words
The medical device of claim 1 , wherein said transducer assembly includes at least one ultrasound transducer.
Claim 8
Dependent Claim
20 words
The medical device of claim 1 , wherein said transducer assembly is moveable through a lumen of said elongate member.
Claim 9
Dependent Claim
61 words
The medical device of claim 7 , wherein said lumen at said front end of said elongate body has a reduced opening smaller than a diameter of said transducer assembly and wherein at least said distal end of said elongate body is radially adjustable to permit said transducer assembly to extend out and retract within said lumen of said elongate body.
Claim 10
Dependent Claim
50 words
The medical device of claim 1 , wherein said heating element comprises a u-shaped heating element having two ends where at least a first end is attached to said elongate member such that rotation of said elongate member rotates said u-shaped electrode permitting coring of tissue to create the channel.
Claim 11
Dependent Claim
38 words
The medical device of claim 1 , wherein said lens comprises a shape which disperses the source signal over a substantial portion of an outer surface of the lens and refracts the reflected signal towards the transducer assembly.
Claim 12
Dependent Claim
20 words
The medical device of claim 1 , where at least one heating element located is retractable into the elongate member.
