Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
125 words
In combination: a plaque-treating instrument for insertion into a vessel through an access site and along the vessel to a desired location and having means for engaging and removing plaque from the remaining wall of the vessel to thereby treat stenosis by enlarging the size of the flow path comprising the lumen of the vessel; a tubular graft for contiguous placement against the treated arterial wall defining the enlarged lumen; a graft carrier for insertion of the graft through the access site and along the vessel to the treated location and comprising means for releasibly holding and selectively deploying the graft into contiguous relation with the remaining wall of the vessel to thereby alleviate restenosis, the carrier being removed from the vessel after graft deployment.
Claim 2
Dependent Claim
125 words
In combination: a plaque-treating instrument for insertion into a vessel through an access site and along the vessel to a desired location and having means for engaging and removing plaque from the remaining wall of the vessel to thereby treat stenosis by enlarging the size of the flow path comprising the lumen of the vessel; a tubular graft for contiguous placement against the treated arterial wall defining the enlarged lumen; a graft carrier for insertion of the graft through the access site and along the vessel to the treated location and comprising means for releasibly holding and selectively deploying the graft into contiguous relation with the remaining wall of the vessel to thereby alleviate restenosis, the carrier being removed from the vessel after graft deployment.
Claim 3
Dependent Claim
46 words
The combination of claim 1 wherein the plaque-treating instrument comprises one or more of the following: a cutting device including but not limited to severing, grinding, chipping, abrading, drilling and rotating blade devices, a dissecting ring, a prying device, a laser device and an ultrasonic device.
Claim 4
Dependent Claim
21 words

Claim 5
Dependent Claim
47 words
The combination of claim 1 wherein the plaque-treating instrument comprises one of an endarterectomy instrument by which plaque and arterial wall tissue are removed from the remaining wall of the vessel and an artherectory instrument by which plaque is removed from the remaining wall of the vessel.
Claim 6
Dependent Claim
26 words
The combination of claim 1 wherein the plaque-treating instrument comprises a dissecting ring comprises at least one of a manually manipulatable ring and a dynamic ring.
Claim 7

Claim 14
Dependent Claim
31 words
The combination of claim 1 wherein the plaque-treating instrument comprises an occlusion reduction instrument comprises at least one of a guidewire, a dynamic wireguide, a dynamic disrupter and a coring catheter.
Claim 15
Dependent Claim
15 words

Claim 17
Dependent Claim
27 words
