Abstract
Abstract This is a procedure for stabilizing or filling an aneurysm in the vasculature. The procedure involves the introduction into the aneurysm of a solid vaso-occlusive device such as a coil or braid and a polymeric composition which may be reformed or solidified in situ. The solid vaso-occlusive device is at least partially surrounded or enveloped by that polymeric composition. The polymeric composition is reformed via light, heat, R.F. or the like to form a rigid mass with the solid vaso-occlusive device. These steps may be carried out sequentially or the steps of introducing the vaso-occlusive device and reforming the polymeric composition may be carried out simultaneously. The procedure may be accomplished using intravascular catheters to access the desired site and to deliver the noted materials.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
58 words
A procedure for at least partially closing a mouth of an aneurysm comprising the steps of: a. introducing a vaso-occlusive device and a formable polymeric material into the mouth and the aneurysm b. reforming said polymeric material in the mouth of the aneurysm to bind said vaso-occlusive device to at least partially close the mouth of the aneurysm.
Claim 2
Dependent Claim
58 words
A procedure for at least partially closing a mouth of an aneurysm comprising the steps of: a. introducing a vaso-occlusive device and a formable polymeric material into the mouth and the aneurysm b. reforming said polymeric material in the mouth of the aneurysm to bind said vaso-occlusive device to at least partially close the mouth of the aneurysm.
Claim 3
Dependent Claim
27 words
The procedure of claim 1 wherein the vaso-occlusive device is electrically conductive and the reforming step is accomplished by introducing an electrical current into said vaso-occlusive device.
Claim 4
Dependent Claim
22 words
The procedure of claim 1 wherein the reforming step which comprises introducing radio frequency current adjacent to the mouth of the aneurysm.
Claim 5
Dependent Claim
20 words
The procedure of claim 1 wherein the reforming step which comprises introducing light adjacent to the mouth of the aneurysm.
Claim 6
Dependent Claim
40 words
A procedure for at least partially filling an aneurysm comprising the steps of: a. introducing a vaso-occlusive device and a bindable material into an aneurysm; b. binding said bindable material in said aneurysm to bind said vaso-occlusive device to itself.
Claim 7
Dependent Claim
40 words
A procedure for at least partially filling an aneurysm comprising the steps of: a. introducing a vaso-occlusive device and a bindable material into an aneurysm; b. binding said bindable material in said aneurysm to bind said vaso-occlusive device to itself.
Claim 8
Dependent Claim
11 words
The procedure of claim 5 wherein the bindable material is polymeric.
Claim 9
Dependent Claim
14 words
The procedure of claim 5 wherein the bindable material binds via introduction of heat.
Claim 10
Dependent Claim
14 words
The procedure of claim 5 wherein the bindable material binds via introduction of light.
