| 20080249612 | PROSTHETIC VALVE THAT PERMITS RETROGRADE FLOW - A prosthetic valve for regulating fluid flow through a body vessel is provided. The valve includes an expandable support frame and a valve leaflet, and includes at least one opening that permits a controlled amount of retrograde flow through the valve when the valve is in a closed configuration. A flap disposed adjacent the opening is able to temporarily and substantially close the opening to contribute to the regulation of retrograde flow proceeding through the valve. | 10-09-2008 |
| 20080255580 | MEDICAL DEVICE DELIVERY SYSTEM WITH SHEATH SEPARATION - Medical device delivery systems and associated methods are provided. Delivery systems according to the invention include an elongated tubular member and a body member, such as a dilator, disposed therein. An intraluminal medical device is disposed on the dilator and within the tubular member prior to deployment. The delivery system includes a means for separating two or more portions of the distal end of the tubular member that aids in deploying the intraluminal medical device from the delivery system by separating two or more portions of the tubular member from each other to facilitate release of the intraluminal medical device from the body member. Various structures can be used for means for separating, including a cutting ring, activateable material on the tubular member, or other suitable structure. The provided devices and methods reduce friction occuring from relative movement between the sheath and dilator during deployment. | 10-16-2008 |
| 20090254174 | Removable Covering for Implantable Frame Projections - The disclosure relates to medical devices for implantation in a body vessel, and methods of using and making the same. A medical device can include a frame with one or more projections each having at least one edge extending from the surface of the frame, and a biocompatible, water-soluble removable material coated over at least a portion of the at least one edge. 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 |
| 20100057191 | IMPLANTABLE VASCULAR DEVICE - An valve prosthesis, such as an artificial venous valve, having a support frame and leaf structure comprising one or more leaflets in which the outer edge of each leaflet engages the inner circumference of the bodily passageway along a serpentine path urged against the passageway by an expandable frame, while the inner edges move in response to fluid to restrict retrograde flow. Optionally, one or more elements can extend from the support frame/leaf structure to provide centering support and/or protection from the leaflet adhering to the vessel wall. In one embodiment, the centering support structure comprises a second or third expandable frames attached to and extending from the proximal and/or distal ends of main valve structure and support frame. In another embodiment, one or more support elements extend outward from the valve support frame to engage the vessel wall to provide greater longitudinal stability. | 03-04-2010 |
| 20100063577 | METHOD OF IMPLANTING A PROSTHETIC VALVE - Methods of implanting a prosthetic valve in a body vessel are provided. A first expandable frame member is delivered to and deployed at a point of treatment in a body vessel. A second expandable frame member is delivered to the point of treatment. The second expandable frame member has an attached graft member that forms a valve adapted to permit fluid flow through the body vessel in a first direction and to substantially prevent fluid flow through the body vessel in a second, opposite direction. After deployment of the first expandable frame member, the second expandable frame member is deployed at the point of treatment such that the second frame member is positioned radially inward of the first frame member within said body vessel to form a prosthetic valve. | 03-11-2010 |
| 20100114296 | INTRALUMENALLY-IMPLANTABLE FRAMES - Implantable frames for use in body passages are provided herein. The implantable frames can include a plurality of hoop members joined by a plurality of longitudinal connecting members to form a tubular frame defining a cylindrical lumen. The plurality of longitudinal connecting members may include first and second longitudinal connecting members joining a first hoop member to a second hoop member such that the first and second longitudinal connecting members extend across an entire space separating the first and second hoop members. | 05-06-2010 |
| 20100174361 | PROSTHETIC VALVE WITH SEMI-RIGID AND FLEXIBLE LEAFLETS - The invention relates to a prosthetic valve for regulating fluid flow through a body lumen. The valve includes a frame and a valve member comprising at least one semi-rigid leaflet and at least one flexible leaflet. | 07-08-2010 |
| 20100286719 | VALVULOTOME DEVICE AND METHOD - Valvulotome devices and methods are provided. Valvulotome devices include one or more valvulotome arms that have a u-shaped curved body with opposing arms and a base portion that extends between the arms. The valvulotome arm defines a notch open at one end on one of the arms and extending into the base portion of the u-shaped curved body. The notch defines an angled surface that provides a cutting edge. Methods of making valvulotome devices are also described. | 11-11-2010 |
