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.
