CONTAINMENT DEVICE FOR SITE-SPECIFIC DELIVERY OF A THERAPEUTIC MATERIAL AND METHODS OF USE
First Claim
1. A containment device for site-specific delivery of a therapeutic material without unintentional leakage into adjacent anatomy, comprisinga. an expandable containment body comprising a naturally-derived collagenous material;
- andb. a delivery device to convey the containment body into a treatment location within a body, the delivery device having a proximal delivery device end, a distal delivery device end, and at least one lumen extending between the proximal delivery device end and the distal delivery device end,wherein the containment body is detachably attached to the distal end of the delivery device.

Abstract
The present invention is directed to devices and methods for the controlled delivery of a therapeutic material into the treatment site to prevent unintentional migration of the therapeutic material from the treatment site. The devices include an expandable containment body made of a naturally-derived collagenous material and a delivery device to convey the containment body into a treatment location within a body. The invention is also directed to a method of treating a bone, an aneurysm, or arteriovenous malformations by providing the containment device.
