International Classification:

A61F 2/06

US Classification:

623 136, 623 115

Abstract:

A medical prosthesis for implantation within the body of a patient comprises a support structure and an anchoring element that comprises a basal portion and at least one barb extending from the basal portion. The anchoring element may be slidably attached to the strut and the strut may include a first stop and a second stop that define a longitudinal zone of movement for the anchoring element. Other devices and methods are described.

International Classification:

A61F 2/06

US Classification:

623 136, 623 115

Abstract:

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.

Abstract:

A coated medical device () including a structure () adapted for introduction into a passage or vessel of a patient. The structure is formed of preferably a non-porous base material () having a bioactive material layer () disposed thereon. The medical device is preferably an implantable stent or balloon () of which the bioactive material layer is deposited thereon. The stent can be positioned around the balloon and another layer of the bioactive material posited over the entire structure and extending beyond the ends of the positioned stent. The ends of the balloon extend beyond the ends of the stent and include the bioactive material thereon for delivering the bioactive material to the cells of a vessel wall coming in contact therewith. The balloon further includes a layer of hydrophilic material () positioned between the base and bioactive material layers of the balloon.

US Classification:

606151

Abstract:

An attachment system for attaching an intravascular device to a vessel wall of a body vessel is disclosed. The attachment system has an intravascular device having a first end and a second end. The intravascular device defines a longitudinal axis along a length thereof. Several struts are connected to one or more ends of the intravascular device. Each strut is configured to move along a strut path relative to the longitudinal axis between an expanded state for engaging the vessel wall and a collapsed state for delivery or retrieval. Each strut has a free end configured to engage the vessel wall in the expanded state.

Abstract:

An attachment system for attaching an intravascular device to a vessel wall of a body vessel is disclosed. The attachment system includes a tubular expandable body defining a lumen therethrough. The tubular expandable body is configured to move between an expanded state to contact the body vessel and a collapsed state for delivery or retrieval. The tubular expandable body is configured to contact the vessel wall along the length of the tubular expandable body in the expanded state when deployed in the body vessel. An intravascular device is held to the exterior side of the tubular expandable body and is configured to contact the vessel wall when the tubular expandable body is in the expanded state and the system is deployed within a body vessel.
