| 20080228256 | Braided Flange Branch Graft for Branch Vessel - A braided flange branch graft formed of a braided super elastic memory material includes a neck between an inner flange and an outer flange. The neck is positioned in a side opening in a sidewall of a main stent graft and the inner flange and outer flange are deployed on opposite sides of the sidewall. The inner flange and the outer flange have a diameter greater than a diameter of the side opening in the sidewall of the main stent graft. Thus, the sidewall of the main stent graft is sandwiched between the inner flange and the outer flange securely and simply mounting the braided flange branch graft to the main stent graft. The braided flange has a substantially unobstructed fluid communication passage therethrough. Further, when stretched into a substantially cylindrical shape for delivery, the braided flange branch graft has a small delivery profile and is extremely flexible. | 09-18-2008 |
| 20080269876 | Repair of Incompetent Heart Valves by Papillary Muscle Bulking - Incompetency or regurgitation of a cardiac valve is treated by injecting a space occupying material or implanting a space occupying device within a papillary muscle or in heart tissue near a papillary muscle to cause lengthening or repositioning of the papillary muscle in a manner that improves coaptation of the valve leaflets and lessens valvular incompetency or regurgitation. The procedure may be performed by open thoracotomy, thoracoscopically, by a tran-endocardial catheter based approach or by a trans-coronary catheter based approach. | 10-30-2008 |
| 20090192601 | Infundibular Reducer Device Delivery System and Related Methods - Described is a delivery system for minimally invasive delivery of a self-expandable stent to a body lumen, and particularly delivery of a prosthetic valve to the right ventricular outflow tract. Also described is a method of loading a stent onto such a delivery system, and a method of delivering a self-expandable stent to a desired anatomic site. | 07-30-2009 |
| 20090248132 | Double-Walled Stent System - A double walled stent system particularly suited for treating abnormalities of the right ventricular outflow tract is disclosed having an exterior stent component and an interior stent component. The exterior stent component includes a plurality of longitudinally-extending connectors such as straight or sinusoidal bands. The interior stent component has a generally tubular cylindrical body and is centered within the exterior stent component. The stent system has a contracted delivery configuration and a radially expanded configuration for contacting the vessel wall. When deployed, the longitudinally-extending connectors of the exterior stent component come in contact with the vessel wall and fix the stent system to the treatment site. The interior stent component also radially expands but remains centered inside the exterior component and makes little to no contact with the vessel wall. | 10-01-2009 |
| 20090248133 | Double-Walled Stent System - A double walled stent system particularly suited for treating abnormalities of the right ventricular outflow tract is disclosed having an exterior stent component and an interior stent component. The exterior stent component is secured to the interior stent component in a non-fixed, sliding relationship. The exterior stent component includes a plurality of longitudinally-extending connectors such as straight or sinusoidal bands. The interior stent component has a generally tubular cylindrical body and is centered within the exterior stent component. The stent system has a contracted delivery configuration and a radially expanded configuration for contacting the vessel wall. When deployed, the longitudinally-extending connectors of the exterior stent component come in contact with the vessel wall and fix the stent system to the treatment site. The interior stent component also radially expands but remains centered inside the exterior component and makes little to no contact with the vessel wall. | 10-01-2009 |
| 20090248142 | Methods, Devices and Systems for Treating Venous Insufficiency - Methods and systems for improving the competency of a venous valve wherein one or more compressor(s) (e.g., space occupying material(s) or implantable device(s)) is/are delivered to one or more location(s) adjacent to a venous valve to compress the venous valve in a manner that causes one or both leaflets of the valve to move toward the other, thereby improving closure or coaptation of the valve leaflets. The compressor(s) may be delivered by an open surgical approach, by a direct percutaneous approach or by a transluminal catheter-based approach. | 10-01-2009 |
| 20090259304 | Devices and Methods for Treating Valvular Regurgitation - A system for treating mitral valve regurgitation includes a tensioning device having a plurality of helical anchors and a tensioning filament. One embodiment of the invention includes a method for attaching a tensioning device to the annulus of a mitral valve in a trans-leaflet configuration, and applying a tension force to the tension filament in order to exert force vectors on the annulus, thereby reshaping the mitral valve annulus so that the coaption of the anterior and posterior leaflets of the mitral is improved during ventricular contraction. | 10-15-2009 |
| 20090270966 | Stent Graft System and Method of Use - A stent graft system and method of use includes a stent graft for fixation at an attachment site with graft material defining at least one opening having an opening perimeter; a support attached to the graft material; a guide rail attached around the opening perimeter; and a helical anchor having a plurality of coils with a point at one end. The plurality of coils are rotatable around the guide rail to cause the pointed end of the coils to penetrate the graft material and the adjacent tissue in contact with the stent graft to sew the stent graft to the attachment site. | 10-29-2009 |
| 20090270976 | Stent Graft Fixation System and Method of Use - A stent graft fixation system and method of use includes a stent graft system for fixation to a vessel wall, the system having a helical anchor and a stent graft. The helical anchor has a number of coils with a point at one end and a helical anchor axis, and the stent graft has a stent graft axis. The coils are operable to sew the stent graft to the vessel wall with the helical anchor axis generally parallel to the stent graft axis. | 10-29-2009 |
| 20090306764 | Compliant Blood Vessel Graft - A graft includes a flexible, resilient, generally tubular external support and a blood vessel segment, carried within and having an ablumenal surface in contact with and supported by the tubular support, the graft being capable of resilient radial expansion in a manner mimicking the radial compliance properties of an artery. | 12-10-2009 |
| 20100049306 | Infundibular Reducer Devices - Described is a prosthetic valve assembly comprising: a radially self-expandable stent configured to expand to bear against a wall of a native body lumen; and an implantable prosthetic valve, having a diameter, the valve being mounted inside the stent; wherein the diameter of the stent is greater than the diameter of the prosthetic valve. | 02-25-2010 |
| 20100152845 | Annuloplasty Device Having Shape-Adjusting Tension Filaments - A system for treating mitral valve regurgitation includes a tensioning device having a flexible annuloplasty ring, a plurality of anchoring members and a tensioning filament attached to the flexible ring. One embodiment of the invention includes a method for attaching a flexible annuloplasty ring to the annulus of a mitral valve, and adjusting the lengths of segments of the tension filament attached to the flexible ring in order to exert force vectors on the annulus, thereby reshaping the mitral valve annulus so that the anterior and posterior leaflets of the mitral valve close completely during ventricular contraction. | 06-17-2010 |
