Abstract: An endoluminal filter including a first support member (105) and a second support member (110) attached to the first support member to form a crossover (106). A material capture structure (115) extends between the first and second support members, the crossover and the first end (102) or the second end (104) of the first support member. The filter includes at least three tissue anchors (805) attached to one support member and at least two tissue anchors (805) attached to the other support member.

Abstract: Embodiments of the invention relate generally to devices and methods for providing filtration of debris within a body lumen. More particularly, embodiments of the invention related to devices and methods for providing distal protection to a medical procedure by filtration of debris generated by the medical procedure using filters having a frame with a slidable crossover point.

Abstract: The present invention relates generally to devices and methods for retrieving or manipulating objects within a lumen. More specifically, embodiments of the invention relate to devices and methods for retrieving or manipulating medical devices from a body lumen. One embodiment of the present invention provides a novel and improved retrieval snare and method of fabricating and using the same. The snare includes a snare wire, having a distal end and a proximal end, for use in the human anatomy, such as but not limited to blood vessels, pulmonary airways, reproductive anatomy, gastrointestinal anatomy, and organs such as the kidneys or lungs. The device enables a user to capture a foreign object located within the human anatomy, grasp said object in a controlled manner, and retrieve and remove said object from the human anatomy.

Abstract: Devices, systems, and methods use a catheter device sized and configured for introduction to a targeted site in a hollow body organ or blood vessel. The catheter device includes a first release mechanisms coupled to the prosthesis to secure at least one region of the prosthesis to the catheter shaft, and a second release mechanism coupled to the prosthesis in cooperation with the first release mechanism to prevent full release of the at least one region of the at least one region of the prosthesis from the catheter shaft after actuation of the first release mechanism. A fastening device sized and configured for introduction to the targeted site in the hollow body organ or blood vessel occupied by the catheter device, includes an actuator to deploy a fastener in the at least one region of the prosthesis after actuation of the first release mechanism and before actuation of the second release mechanism.

Abstract: Devices and methods for delivering conduits into the wall of a patient's heart to communicate a coronary vessel with a heart chamber. The devices are passed through the coronary vessel and the heart wall to place the conduit and establish a blood flow path between the vessel and the heart chamber. Additional devices and methods are provided for removing tissue from a coronary vessel or the heart wall to establish a flow path between the coronary vessel in communication with the heart chamber.

Abstract: Devices and methods utilized in performing transmyocardial coronary bypass include retractors used to engage and support myocardial tissue, and mechanisms for supporting coronary vessels so as to allow precise entry into a vessel lumen. In addition, various conduits are provided having a configuration that permits their positioning in a heart wall to place a coronary vessel in communication with a heart chamber.

Abstract: Devices, systems and methods support tissue in a body organ for the purpose of restoring or maintaining native function of the organ. The devices, systems, and methods do not require invasive, open surgical approaches to be implemented, but, instead, lend themselves to catheter-based, intra-vascular and/or percutaneous techniques.

Abstract: An intravascular device and method of constructing an intravascular device. The device has a proximal portion which is stiffer than a distal portion. The device of the present invention may also be advanced through small vessels without the aid of a guidewire although a guidewire may be used when necessary. The device may be manufactured in a number of different ways and a preferred method is to use an expanded PTFE liner at the distal portion and an etched PTFE liner along the proximal portion. The device also has a number of different jacket sections, preferably at least four, with increasing durometer towards the proximal end and a braided section with varying pic along the length.
