Abstract
Devices for the occlusion of body cavities, such as the embolization of vascular aneurysms and the like, and methods for making and using such devices. The devices may be comprised of novel expansile materials, novel infrastructure design, or both. The devices provided are very flexible and enable deployment with reduced or no damage to bodily tissues, conduits, cavities, etceteras.
Claims19
An occlusion device comprising:
- an elongated, expansile element having a solid mass, that is flexible in an untreated state, consisting essentially of a poly(ethylene glycol) macromer and a pH sensitive monomer;
- and
- a carrier element comprising a plurality of loops forming a helical shape disposed around the expansile element,
- wherein the plurality of loops are spaced to form at least one gap and the at least one gap is between about 0.00025 inches and about 0.2 inches.
