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: 9
Claim 1
Independent Claim
83 words
An occluding device for placement in the human
body, comprising an elongated braided body member
comprising woven ribbons, at least a majority of which
comprise super-elastic alloys, and further having a
proximal end and a distal end and a lumen between said
proximal and distal ends, an electrolytically detachable
joint attached to said body member 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
31 words
