Disclosed are methods and devices for isolating all three of the left subclavian, left common carotid and brachiocephalic arteries from embolic debris that might flow through the aortic arch, via a single access point. A system may include an elongate flexible tubular sheath, having a proximal end and a distal end, and an inner member extending through the sheath and moveable relative to the sheath. A left subclavian element may be supported by the inner member. A filter membrane may be configured to isolate the aorta from the brachiocephalic, left common carotid and left subclavian arteries when the left subclavian element is expanded within the left subclavian artery and the sheath is retracted to expose the membrane. The left subclavian element may include a self expandable frame, which may carry a left subclavian filter.

Systems and methods for protecting the cerebral vasculature

A valve implant includes a valve leaflet prosthesis having a wire frame, a leaflet blade panel attached to the wire frame, and one or more tether struts extending from the wire frame, and a stent having a first end portion and a second end portion along a longitudinal stent axis, and a flexible extended stent strut extending longitudinally from the first end portion, wherein the one or more tether struts of the valve leaflet prosthesis is rotatably coupled to the flexible extended stent strut in a manner such that the one or more tether struts are rotatable about a rotational axis which is parallel to the one or more tether struts and which extends transverse to the longitudinal stent axis. A delivery system for the valve implant and a method of preparing the delivery system are also disclosed.

Valve implant, delivery system and method

Some embodiments relate in part to endovascular prostheses and methods of deploying same. Embodiments may be directed more specifically to stent grafts and methods of making and deploying same within the body of a patient. Stent embodiments may include tapered struts for an even distribution of strain. Stent embodiments may also include portions which are enlarged in a circumferential direction which may be configured to stabilize the stent in a constrained state.

Durable stent graft with tapered struts and stable delivery methods and devices

A coaxial multilumen annulus plane catheter, including an outer pigtail catheter enclosing one or two additional lumens, each housing either a slidable shaped wire or a second pigtail catheter shaped to fit into a wide range of annulus diameters and/or depths. In embodiments, the device may include a catheter delivery handle with thumb/finger-actuated sliders that extend or retract the shaped wires and are sized to enable side-to-side or radial motion, imparting a torque to the pre-shaped wires which translates the length of the wires to enable individually controlled rotation or sweep of each wire to accommodate different annulus diameters. The delivery handle includes hemostasis controls and flush ports. In other embodiments, a handle is obviated by direct lumen axial and rotational control at a proximal end.

Annulus plane catheter

Some embodiments relate in part to endovascular prostheses and delivery catheter systems and methods for deploying same. Embodiments may be directed more specifically to graft bodies having self-expanding members, including inflatable graft bodies, and catheters and methods for deploying same within the body of a patient.

Delivery catheter for endovascular device

A multi-lumen catheter having a guidewire for each lumen, the catheter having a proximal-end assembly and an elongate tube including a multi-lumen medial portion and a distal-end portion. Each guidewire extends from the proximal end assembly through the medial portion to a lumen convergence portion which merges the lumens into a single output lumen. The distal-end portion includes (a) the lumen convergence portion, (b) an intermediate section surrounding the output lumen, and (c) a tapered tip surrounding the output lumen, with the diameter of each lumen of the multiple lumens other than the output lumen being sized to match the guidewire therein such that the guidewire is able to move therealong while being constrained laterally and remaining substantially coaxial with its lumen, and the diameter of the single output lumen being equal to the diameter of the largest diameter lumen of the multiple lumens.

Multi-lumen intravascular catheter with inner converging lumens for multiple guidewire control

Embodiments are directed in part to endovascular prostheses and methods of deploying same. Embodiments may be directed more specifically to stent grafts and methods of positioning and deploying such devices within the body of a patient.

Advanced endovascular graft and delivery system

In a multiple-lumen catheter having multiple guidewires for treatment of vascular blockages, the catheter comprising a proximal-end assembly, a distal-end portion and a multi-lumen medial portion therebetween, the improvement wherein: (1) the multiple guidewires are preloaded in the catheter, each guidewire in its own single-guidewire lumen extending from its own guidewire entry port in the proximal-end assembly to a lumen convergence portion; and (2) the distal-end portion includes: (a) the lumen convergence portion along which the multiple lumens merge into a single output lumen sized to match the largest-diameter lumen of the multiple lumens, (b) an intermediate distal-end section connected to the lumen convergence portion and surrounding the single output lumen continuing therethrough, and (c) a tapered tip surrounding the single output lumen continuing therethrough.

Multi-lumen intravascular catheters with inner converging lumens for multiple guidewire control

A surgical stereoscopic visualization system having a microscope head, dual cameras mounted on or proximate the microscope head for real time video capture of a subject in an operative field, a video processing and display system to receive separate video streams from the cameras and to combine the separate video streams into a time-aligned stereoscopic image. The processed image is displayed on a matrix display screen in at least one movable head-mounted stereoscopic display. Movement of the head mounted display is accomplished with a support structure on a headband that accurately positions the display screen in front of the user's eyes, yet allows the user to precisely move the display screen either manually or by motorized means into and out of the user's line of sight, thereby facilitating uninterrupted use of the hands while working in the surgical suite.
