A prosthetic heart valve includes a stent extending from an inflow end to an outflow end. The stent has a commissure attachment feature between the inflow end and the outflow end. The commissure attachment feature has a frame defining an opening. The valve further includes a skirt coupled to the frame of the commissure attachment feature, and at least two leaflets coupled to the skirt. Each leaflet is coupled to the skirt both through the opening of the commissure attachment feature and outside of the commissure attachment feature.

A delivery device for a collapsible prosthetic heart valve includes an inner shaft, an outer shaft, and a distal sheath. The distal sheath may be disposed distal to the outer shaft and about a portion of the inner shaft to form a compartment with the inner shaft, the compartment being sized to receive the prosthetic heart valve in a collapsed condition. The inner shaft and the distal sheath may be movable relative to one another. The delivery device may also include a tube member and an outer sleeve overlying the tube member. The tube member may be configured to rotate or twist upon axial movement of the outer sleeve with respect to the tube member, the rotation or twisting of the tube member configured to rotate the prosthetic heart valve when the prosthetic heart valve is received within the compartment in the collapsed condition.

Active alignment of commissures in prosthetic heart valve implantation

A prosthetic heart valve includes a non-collapsible annular frame extending in a longitudinal direction between an inflow edge and an outflow edge, and a valve assembly connected to the frame. The frame includes a plurality of annularly spaced commissure posts adjacent the outflow edge, each of the commissure posts including a tip and a post slot spaced apart from the tip. The prosthetic heart valve further includes a radiopaque element including an elongated main body having a first end and a second end. The radiopaque element may extend around the tip and through the post slot of at least one of the commissure posts so that a portion of the main body extends between the slot and the tip. Alternatively or additionally, a radiopaque element may be positioned adjacent a base of the frame.

A fixation system for repairing a pars fracture includes a needle guide configured to be docked on a lamina of the pars, a needle, a guidewire, and a screw assembly. A portion of the needle is configured for insertion through a passage of the needle guide. A portion of the guidewire is configured for insertion through a passage of the needle. The screw assembly includes a collar and an elongated portion, the collar being movable with respect to the elongated portion. A portion of the screw assembly is configured to contact the lamina co-axially with the guidewire.

Fixation systems and methods of repairing a pars fracture

A delivery device for a collapsible prosthetic heart valve includes an inner shaft, an outer shaft, and a distal sheath. The distal sheath may be disposed distal to the outer shaft and about a portion of the inner shaft to form a compartment with the inner shaft. The compartment may be sized to receive the prosthetic heart valve. The inner shaft and the distal sheath may be movable relative to one another. A spine may extend along the outer shaft, the spine biasing the outer shaft so that the outer shaft tends to bend in a pre-determined direction.

A prosthetic heart valve includes a radially collapsible and expandable stent, a cuff and leaflets sutured thereto. The heart valve extends axially between an inflow end and an outflow end and the stent includes a layout of struts and nodes having a hybrid combination of vertical struts and oblique struts in the form of diamond-shaped and half diamond-shaped cells. The layout of the structure is configured to preserve a low cell density of material used in the stent to reduce the stent profile while in a collapsed state and to improve the deployment accuracy of the stent into the native valve annulus.

Low profile expandable heart valve

A spinal plate bender includes an actuation assembly, a collet, and a head portion. The actuation assembly includes a housing, a lever pivotably coupled to the housing, a linkage pivotably coupled to the lever, and an actuation shaft operatively coupled with the linkage. The lever is transitionable between a neutral position and an actuated position, which imparts axial displacement to the actuation shaft. The collet includes a proximal section, a sleeve section extending distally from the proximal section, and a coupling section extending distally from the sleeve section. The head portion is configured to support a spinal plate. The head portion includes an anvil portion coupled to a distal end portion of the actuation shaft. The anvil portion is configured to engage a spinal plate to cause bending of a spinal plate supported in the head portion.

A prosthetic mitral valve includes a collapsible and expandable stent extending from an inflow end to an outflow end. A collapsible and expandable valve assembly is disposed within the stent. The valve assembly includes a plurality of anterior leaflets and one posterior leaflet. The posterior leaflet has a larger surface area than any of the anterior leaflets. When implanted in the native mitral valve annulus, the smaller size of the anterior leaflets and the corresponding smaller size of an anterior portion of the stent reduce the likelihood of interference with blood flowing through the native aortic valve, while also reducing the likelihood of ventricular fibrillation.
