Stent Adapted For Tangle-Free Deployment
Stent Adapted For Tangle-Free Deployment
US Patent:

International Classification:
A61F 206
US Classification:
623 114, 623 113, 623 115
Abstract:
An expandable stent prosthesis is disclosed in which the apices of the bends located at at least one end of the stent are individually twisted at an angle to the circumference of the stent to form a fan blade-like arrangement when viewed from that end. The fan blade-like arrangement allows the stent to expand from the compressed condition during deployment such that likelihood of a strut or bend of the stent become entangled with a barb or adjacent strut or bend, is reduced. In one embodiment of the invention, the fan blade-like arrangement results from plastically deforming the individual apices, while in another embodiment, the apices are twisted into the fan blade-like arrangement during the loading process, such as by use of a suture thread to pull the apices into alignment.

Assignee:
Cook Medical Technologies LLC - Bloomington IN
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.

International Classification:
A61B 17/11
US Classification:
606153
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.

International Classification:
A61B 17/11
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.
