Abstract
Abstract This is a braided tubular device used in the occlusion of various lumen or cavities in the body. In particular, it may be used to form an endovascular occlusion. Most desirably, it is braided of a majority of super-elastic alloy ribbons and therefore is both inherently non-stretching and most difficult to permanently deform. It may be deployed using an electrolytically severable joint. A radio-frequency modulated current may optionally be applied to the device after its placement in the body. The elongated device preferably is insulated along its length to optimize its occlusive activity without harm to the body.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
94 words
An occluding device for placement in the human body comprising an elongated body member formed from a plurality of ribbons, said ribbons being braided with each other, at least a majority of said ribbons are formed from super-elastic alloys, said body member having a proximal end and a distal end and a lumen between said proximal and distal ends, an electrolytically detachable joint attached to said proximal end capable of conducting an electrical current through said joint to said body member, and wherein said body member is substantially covered with a polymeric insulative material.
Claim 2
Dependent Claim
94 words
An occluding device for placement in the human body comprising an elongated body member formed from a plurality of ribbons, said ribbons being braided with each other, at least a majority of said ribbons are formed from super-elastic alloys, said body member having a proximal end and a distal end and a lumen between said proximal and distal ends, an electrolytically detachable joint attached to said proximal end capable of conducting an electrical current through said joint to said body member, and wherein said body member is substantially covered with a polymeric insulative material.
Claim 3
Dependent Claim
31 words
The device of claim 1 wherein a minority of said ribbons comprise a radio-opaque material selected from the group consisting of gold, platinum, palladium, rhodium, rhenium, tungsten, their alloys and mixtures.
Claim 4
Dependent Claim
17 words
