CLOSURE DEVICE AND METHOD OF CLOSING A BODILY OPENING

摘要

In one embodiment, a device (10) for closing or occluding ASDs and PFOs, or other bodily passageways, includes a circumferential frame (14), a sheet (18) of biocompatible material attached to the frame, and at least one anchor (22) attached to the sheet of biocompatible material. In another embodiment, the closure device includes a circumferential frame, at least one crossbar (20) extending across and attached to the frame, at least one anchor connected to at least one crossbar; and at least one sheet of biocompatible material (such as ECM material) attached to the frame. The anchor includes at least one grasping member (34) having a structure, such as a wired loop, which is configured for releasable attachment to a delivery release member, which facilitates delivery of a closure device collapsibly disposed in a delivery catheter. Alternatively, one or more anchor end pairs may be connected to a delivery bar (36) enhancing delivery and retrieval of the device.
