A stented valve including a stent structure including a generally tubular body portion having a first end, a second end, an interior area, a longitudinal axis, and a plurality of vertical wires extending generally parallel to the longitudinal axis around a periphery of the body portion, wherein the plurality of vertical wires includes multiple commissure wires and at least one structural wire positioned between adjacent commissure wires, and a plurality of V-shaped wire structures having a first end, a second end, and a peak between the first and second ends, wherein a first end of each V-shaped structure extends from a first vertical wire and a second end of each V-shaped structure extends from a second vertical wire that is adjacent to the first vertical wire, wherein each V-shaped structure is oriented so that its peak is facing in the same direction relative to the first and second ends of the body portion, and a valve structure including a plurality of leaflets attached to the stent structure within the tubular body portion.

A prosthetic heart valve for replacing a native valve includes a stent, a valve assembly, and a radiopaque element. The stent has a plurality of commissure attachment features. The valve assembly includes a plurality of leaflets and first and second cuffs. The first cuff has a proximal edge relatively close to the inflow end of the stent. The second cuff may be annularly disposed about the stent radially outward of the first cuff and radially outward of the stent. The proximal edge of the first cuff is coupled to the proximal edge of the second cuff substantially continuously along a circumference of the inflow end of the stent so that a pocket is formed between the first cuff and the second cuff. The radiopaque element is disposed within the pocket and aligned in a longitudinal direction of the stent with at least one of the plurality of commissure attachment features.

Systems and methods for native heart valve repair includes an anchor. The anchor includes an anchor body configured to transition from a first configuration, in which the anchor body is straightened for transvascular delivery to the native heart valve, to a second configuration comprising at least two turns for implanting at the native heart valve. Two or more of the at least two turns in the second configuration have a diameter smaller than a major axis of the native heart valve.

A mitral valve system comprising a first docking component and a second valvular component that are delivered via a single delivery catheter. The first component is located distal to the second component and provides a detachable rail to allow the second component to accurately position and lock with the first component. The first component has fixation members that are activated by either by a torus balloon or via fiber that does not restrict blood flow during delivery or during fixation member activation.

A prosthetic assembly configured for endovascular placement within an aortic arch and method of use thereof. The prosthetic assembly includes a proximal aortic stent-graft prosthesis configured to be positioned within a proximal portion of the aortic arch adjacent to the brachiocephalic artery, a distal aortic stent-graft prosthesis configured to be positioned within a distal portion of the aortic arch adjacent to the left subclavian artery, a first branch stent-graft prosthesis configured to be positioned within the brachiocephalic artery and a second branch stent-graft prosthesis configured to be positioned in one of the left common carotid and the left subclavian artery. When deployed, a proximal end of the first branch stent-graft prosthesis is disposed within a lumen of the proximal aortic stent-graft prosthesis to proximally displace the ostium of the brachiocephalic artery. When deployed, a proximal end of the distal aortic stent-graft prosthesis is disposed within the distal end of the proximal aortic stent-graft prosthesis to form an overlap between the proximal and distal aortic stent-graft prostheses. The overlap is relatively increased by the first branch stent-graft prosthesis proximally displacing the ostium of the brachiocephalic artery.

A scaffold includes a radiopaque marker connected to a strut. The marker is retained within the strut by a head at one or both ends. The marker is attached to the strut by a process that includes forming a rivet from a radiopaque bead and attaching the rivet to the marker including deforming the rivet to enhance resistance to dislodgement during crimping or balloon expansion. The strut has a thickness of about 100 microns.

Devices, systems, and methods for implanting a patient-specific prosthesis at a treatment site in a patient are disclosed herein. In some embodiments, a patient-specific prosthesis includes a tubular graft and a coupling member. A fenestration can be disposed in the tubular graft, the fenestration corresponding to a predicted branch blood vessel location. The coupling member can be disposed about the fenestration. The coupling member can include a coil configured to expand from a first configuration to a second configuration in response to the application of an expanding force. The coil can be configured to contract to a third configuration upon removal of the expanding force.

The present invention relates to devices, assemblies and methods for monitoring radial expansion of a prosthetic valve during prosthetic valve implantation procedures.

An assembly includes an implant body and a delivery apparatus. The implant body includes a lattice structure, an adjustment member, and a control device. The lattice structure is circumferentially expandable and contractible. The adjustment member and the control device are coupled to the lattice structure. Actuating the adjustment member results in circumferential expansion or contraction of the lattice structure. The delivery apparatus includes a rotatable adjustment tool and a locking mechanism comprising a controllable catch coupled to an end portion of the rotatable adjustment tool. The rotatable adjustment tool is configured to actuate the adjustment member of the implant body upon rotation of the rotatable adjustment tool. The controllable catch of the locking mechanism is configured to selectively couple the rotatable adjustment tool to the adjustment member of the implant body.

A method of removing embolic material from a vessel with mechanical and aspiration assistance. The method comprises the steps of providing an aspiration catheter having a central lumen and a distal end, advancing the distal end of the aspiration catheter to obstructive material in a vessel, applying vacuum to the central lumen to draw clot into the central lumen, introducing a thrombus engagement tool into the central lumen, and manually manipulating the tip to engage clot between the tip and an inside wall of the central lumen.
