Abstract: Apparatus and methods are provided for use in filtering emboli from a vessel and/or performing thrombectomy and embolectomy, wherein a vascular device disposed on a guidewire comprises a support hoop disposed from a suspension strut. Alternately, a support hoop having an articulation region may be directly connected to a region proximate the distal end of the guidewire. A blood permeable sac is affixed to the support hoop to form a mouth of the blood permeable sac. The support hoop is disposed obliquely relative to the longitudinal axis of the guidewire and is capable of being properly used in a wide range of vessel diameters. The vascular device collapses during removal to prevent material from escaping from the sac. A delivery sheath and introducer sheath for use with the vascular device of the present invention are also provided.

Abstract: Embolic protection filtering devices and methods for making and using the same. An example filtering device includes a filter wire, a filter including a filter loop coupled to the filter wire, and a filter membrane coupled to the filter loop. A plurality of cam members may be coupled to the filter loop. Alternatively, the filter loop may include a plurality of strut members coupled thereto. The cam members and/or the strut members may help to stabilize the longitudinal position of the filtering device within a body lumen.

Abstract: A conduit is provided to provide a bypass around a blockage in the coronary artery. The conduit is adapted to be positioned in the myocardium or heart wall to provide a passage for blood to flow between a chamber of the heart such as the left ventricle and the coronary artery, distal to the blockage. The stent is self-expanding or uses a balloon to expand the stent in the heart wall. Various attachment means are provided to anchor the stent and prevent its migration. In one embodiment, a conduit is provided having a distal top which is more preferably a ball top, wire top, flare top or flip-down top. These top configurations anchor the shunt at one end in the coronary artery.

Abstract: An embolic protection filter. In some embodiments, the device includes an elongate shaft, a filter coupled to the shaft, and a proximal stop coupled to the shaft.

Abstract: A retrograde flow system is configured for treating an artery. The system includes an arterial access device adapted to be introduced into an artery and receive blood flow from the artery. A shunt fluidly is connected to the arterial access device, wherein the shunt provides a pathway for blood to flow from the arterial access device to a return site. A flow control assembly is coupled to the shunt and is adapted to regulate blood flow through the shunt between at least a first blood flow state and at least a second blood flow state. A shut-off valve assembly automatically blocks fluid flow through the shunt in response to injection of the fluid into the arterial access device.

Abstract: A clip-based vascular closure devices is configured to be pre-applied to a blood vessel prior to insertion of a vascular access device (such as a procedural sheath) through an incision, puncture, penetration or other passage through the blood vessel. In an embodiment, the disclosed closure device is applied in a carotid artery via a transcervical access such as by forming an incision in the patient's neck to in order to access the blood vessel or other body lumen.
