| 20080245374 | FISTULA PLUGS HAVING INCREASED COLUMN STRENGTH AND FISTULA PLUG DELIVERY APPARATUSES AND METHODS - The present invention provides, in certain aspects, medical devices deliverable into passageways and other open spaces in the body. In one embodiment, the invention provides a fistula plug for delivery into a fistula tract. This fistula plug comprises an elongate plug body, and a removable core material that is received in the plug body and effective to increase the column strength of the plug body. The plug body may be formed with one or more of a variety of biocompatible materials including some that are naturally derived and some that are non-naturally derived. The present invention also provides apparatuses and methods for delivering these and other medical devices into the body. One such apparatus comprises a fistula plug having a plug body, and a removable delivery device received in the plug body, wherein the delivery device is effective to deliver the plug body into a fistula tract when advanced therethrough. | 10-09-2008 |

The projections can be barbs positioned to engage the interior wall of a body vessel or to attach a material, such as a valve leaflet or graft, to the frame. The removable material can be dissolved within a body vessel upon implantation, thereby exposing the at least one edge. Methods of making an implantable medical device and methods of treating a subject are also disclosed. | 10-08-2009 |
| 20100016953 | Anchoring Barb for Attachment to a Medical Prosthesis - Disclosed is an anchoring element for an implantable prosthesis that includes a barb, wherein the anchoring element, which includes a basal portion, comprises a thin layer of material, such as a cannula or sheet of metal, that extends or wraps at least partially around the strut of the prosthesis to which it is attached. The barb is configured to extend outward from the basal portion to penetrate adjacent tissue. The anchoring element is either permanently affixed to the strut, such as by laser or spot welding, crimping, or some other method of bonding, or allowed to slide longitudinally over the strut between two points or stops in order to relieve any excessive loads placed upon the barb that could cause fracture. The anchoring element and strut may be configured to limit axial rotation of the barb, while still allowing longitudinal movement. In another embodiment, the slidable anchoring element may be manipulated following initial deployment to reorient the barb toward the implantation site. | 01-21-2010 |
| 20100114300 | MEDICAL DEVICE WITH LEAK PATH - Medical devices that provide valves for regulating fluid flow through a body vessel are provided. The valves include a support frame having one or more adaptations for forming a leak path between the support frame and an interior wall of a body vessel in which the valve is implanted. A controlled amount of retrograde flow is able to flow through the leak path when the valve is implanted in a body vessel. | 05-06-2010 |
