Abstract: An implantable device having a composite weave graft is disclosed. The device comprises a graft body forming a lumen defining a longitudinal axis and comprising proximal and distal ends. The graft body comprises a composite of low dernier yarns and polymeric yarns configured for low profile delivery and radial elongation relative to the longitudinal axis during use. The graft body has a first portion and a second portion extending from the first portion. The first portion comprises at least one expandable stent radially attached thereto for support and the second portion having corrugations for enhanced kink resistance.

Abstract: Various stent structures are provided with improved axial and torsional flexibility. One type of stent structure includes multiple segmented stent structures connected to each other by biodegradable interconnectors. A delivery system adapted to delivery the multiple segmented stents is also described. Another type of stent structure includes biodegradable connectors that are incorporated into a framework of non-biodegradable interconnecting members that form the support structure of the stent. The biodegradable connectors in both stent structures degrade or are absorbed after the stent is deployed. Stabilizing elements may be provided to the stent structures to supplement the stiffness of the stent with stability during loading and deployment.

Abstract: The invention relates to medical devices, systems and methods for preventing the embolic material flowing about a junction of at least one branch blood vessel and another blood vessel from entering the other blood vessel. The device includes a self cleaning flexible filter and a frame. The external surface of the filter is configured to temporarily trap at least some of the embolic material flowing about the junction as a result of the blood inflow though the filter. The filter is also configured to expel the trapped embolic material into the other blood vessel.

Abstract: A system for delivering and deploying an expandable endoluminal prosthesis comprises a delivery catheter and a sheath. The delivery catheter has a proximal end and a distal end and is slidably disposed within a lumen of the sheath. An operating mechanism comprises a contractible air vessel that couples the sheath and the delivery catheter so that contraction of the air vessel causes the sheath to retract proximally over the delivery catheter. Additional aspects of the invention include a method of deploying an expandable endoluminal prosthesis.

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.
