FOAM OCCLUSION DEVICE

摘要

An occlusion device comprising a plurality of expandable hydrophilic foam elements is described. When the device is deployed to a body vessel or a body cavity, it expands radially due to uptake of liquid from the body fluids with which it is in contact. The device may optionally have a surrounding meshwork, an inner spring, and a screw-type deployment mechanism. A method of deploying the device is also provided.

1. A device for occlusion of a body vessel, the device comprising:
a coil spring having a proximal end and a distal end, defining a longitudinal axis; a proximal collet disposed to the proximal end and a distal collet to the distal end; at least one expandable element disposed radially about a portion of the coil spring; and a covering disposed on the proximal collet about the proximal end, the covering extending from the proximal collet about the coil spring and the at least one expandable element, the covering being disposed on the distal collet about the distal end.
