Abstract
Disclosed are devices for removing a matter from a body cavity of a patient. One of such devices has an elongated carrier having a distal portion adapted to move through or within the cavity and a proximate portion. A radially expandable polymer is circumferentially attached to the distal portion of the carrier and adapted to enter the matter while in a compressed configuration and capable of transitioning to an expanded configuration while inside the matter to penetrate and engage it from within. Methods of removing a matter from a body cavity and methods of localized delivery of a therapeutic agents also are disclosed.
