Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
81 words
A process for paving or stabilizing an irregularly contoured interior surface of a body vessel or organ in an animal, including man, comprising introducing flowable polymeric material onto and filling said irregularly contoured interior surface of the vessel or organ and reconfiguring the polymeric material to form a layer of polymer, said polymer layer having an outer surface which conforms with and is affixed to the irregularly contoured interior surfaces of the vessel or organ and a smooth inner luminal surface.
Claim 2
Dependent Claim
81 words
A process for paving or stabilizing an irregularly contoured interior surface of a body vessel or organ in an animal, including man, comprising introducing flowable polymeric material onto and filling said irregularly contoured interior surface of the vessel or organ and reconfiguring the polymeric material to form a layer of polymer, said polymer layer having an outer surface which conforms with and is affixed to the irregularly contoured interior surfaces of the vessel or organ and a smooth inner luminal surface.
Claim 3
Dependent Claim
15 words
A process as described in claim 1, wherein the polymeric material is a biodegradable polymer.
Claim 4
Dependent Claim
28 words
A process as described in claim 1 or 2 wherein the polymeric material is applied in a preshaped form to the interior surface of the vessel or organ.
Claim 5
Dependent Claim
32 words
A process as described in claim 2, wherein the layer of biodegradable polymer as applied has a thickness of about 0.005 mm to 0.50 mm, so as to create a thin layer.
Claim 6
Dependent Claim
31 words
A process as described in claim 2, wherein the layer of biodegradable polymer is about 0.05 mm to 5.0 mm so as to impart structural stability to the organ or vessel.
Claim 7
Dependent Claim
25 words
A process as described in claim 2 wherein the biodegradable polymer is selected from the group consisting of a homopolymer, a binary and ternary copolymer.
Claim 8
Dependent Claim
25 words
A process as described in claim 6 wherein the polymer is selected from the group consisting of glycolic acid, lactic acid, delta-valerolactone, p-dioxanone, and epsilon-caprolactone.
Claim 9
Dependent Claim
18 words
A process as described in claim 6 wherein the biodegradable polymer constitutes a blend of homopolymers or copolymers.
Claim 10
Dependent Claim
16 words
A process as described in claim 6 wherein the biodegradable polymer is cross-linked with a biscaprolactone.
Claim 11
Dependent Claim
14 words
A process as described in claim 2, wherein the biodegradable polymer is poly (epsilon-caprolactone).
Claim 12
Dependent Claim
14 words
A process as described in claim 2, wherein the polymer contains a pharmaceutical agent.
Claim 13
Dependent Claim
16 words
The process as described in claim 11, wherein multiple polymers containing various pharmacological agents are applied.
Claim 14
Dependent Claim
14 words
A process as described in claim 2 wherein the vessel is a coronary artery.
Claim 15
Dependent Claim
27 words
A process as described in claim 1, wherein a catheter is used to enter the interior of the vessel or organ and to apply the polymer layer.
Claim 16
Dependent Claim
65 words
A process for paving an irregularly contoured interior surface of a coronary artery in an animal, including man, comprising flowing poly(epsilon-caprolactone) onto the irregularly contoured interior surface of the artery and reconfiguring the poly(epsilon-caprolactone) to form a layer, said layer having an outer surface which conforms with and is affixed to the irregularly contoured interior surface of the artery and a smooth inner luminal surface.
Claim 17
Dependent Claim
65 words
A process for paving an irregularly contoured interior surface of a coronary artery in an animal, including man, comprising flowing poly(epsilon-caprolactone) onto the irregularly contoured interior surface of the artery and reconfiguring the poly(epsilon-caprolactone) to form a layer, said layer having an outer surface which conforms with and is affixed to the irregularly contoured interior surface of the artery and a smooth inner luminal surface.
Claim 18
Dependent Claim
18 words
A process as described in claim 15 wherein a catheter is used to introduce poly(epsilon-caprolactone) into the artery.
Claim 19
Dependent Claim
23 words
A process as described in claim 1 wherein the polymer is applied in such a manner as to shape the vessel or organ.
