PROSTHETIC HEART VALVE HAVING NON-CYLINDRICAL FRAME
An implantable prosthetic device can include a frame that is radially expandable and compressible between a radially compressed configuration and a radially expanded configuration. The frame can have a first set of a plurality of struts extending in a first direction, and a second set of a plurality of struts extending in a second direction, and each strut of the first set of struts can be pivotably connected to at least one strut of the second set of struts. Each strut can be curved helically with respect to a first, longitudinal axis of the frame, and each strut can be curved with respect to a second axis that is perpendicular to the first, longitudinal axis of the frame.
Apparatus and methods for implanting a replacement heart valve
Anchors and systems for docking a prosthetic heart valve at a native heart valve are disclosed. An anchor can include at least three coils and a seal positioned between at least two adjacent coils of the at least three coils. The seal circumscribes at least a portion of the at least two adjacent coils and has opposite ends that are spaced away from corresponding opposite ends of the at least three coils.
Medical device for embolic protection
Medical device for embolic protection in an aortic arch, comprising a catheter having a shaft and a distal end portion of the shaft, an expandable embolic protection device having a filter membrane and a frame. The frame comprises a frame loop and an elongated frame shaft having a distal end portion connected to the frame loop in a connection point, in its expanded state the frame loop spans said filter membrane and bending means to bend the distal end portion of the catheter and/or the distal end portion of the frame shaft. The medical device comprises a protective state in which the distal end portion of the catheter is bent, the embolic protection device is expanded, the frame shaft extends in a longitudinal direction of the bent distal end portion and the expanded frame loop being completely positioned distally of the connection point.
Devices and methods for cutting lenticular tissue
An exemplary surgical device includes an element positionable within a shaft having a lumen defined therethrough with the element movable from a stored position to a deployed position in which a larger portion of the element extends out of the distal end of the lumen. The element forming a closed loop which is positioned around the lens while the lens is within a capsular bag. The closed loop is reduced in size to form a cut in the lens.
Artificial cervical and lumbar disc system
An artificial replacement disc includes a pair of substantially parallel plates formed to occupy a space defined by vertebral endplates, each of the plates including a plurality of spikes on a first surface and a concave trough formed on a second surface opposite of the first surface. A mobile core includes a core rim with opposing convex surfaces extending from opposite sides of the core rim, the mobile core being capable of being disposed between the pair of plates to permit the vertebral endplates to move relative to one another. The spikes on each of the plates extend substantially away from the mobile core and the convex surfaces are formed to integrally fit within the concave trough of at least one of the plates. The core rim limits lateral movement of the mobile core relative to the parallel plates. One or more insertion tools for inserting and implanting the replacement disc are also described.
Prosthetic heart valves
Prosthetic heart valves may be delivered to a targeted native heart valve site via one or more delivery catheters. In some embodiments, the prosthetic heart valve includes structural features that securely anchor the prosthetic heart valve to the anatomy at the site of the native heart valve. Such structural features can provide robust migration resistance. In addition, the prosthetic heart valves can include structural features that improve sealing between the prosthetic valve and native valve anatomy to mitigate paravalvular leakage. In particular implementations, the prosthetic heart valves occupy a small delivery profile; thereby facilitating a smaller delivery catheter system for advancement to the heart. Some delivery catheter systems can include a curved inner catheter to facilitate deployment o the prosthetic heart valve to a native tricuspid valve site via a superior vena cave or inferior vena cave.
ACCOMODATING INTRAOCULAR OPTIC ASSEMBLIES
Improvements to accommodating intraocular optic assemblies are disclosed herein. The accommodating intraocular optic assembly can include an optic and at least one stanchion. The at least one stanchion can extend a length between a base end and a distal end. The distal end can be operably engaged with the optic directly or indirectly. The at least one stanchion can include an outer sleeve defining a through-aperture. The at least one stanchion can also include at least one inner member positioned within the through-aperture.
Elliptical heart valve prostheses, delivery systems, and methods of use
A heart valve prosthesis includes a frame and a prosthetic disposed within a lumen of the frame. The frame includes a plurality of struts and crowns and has a radially collapsed state and a radially expanded state. A stiffness of the plurality of struts is varied by varying the width of at least one strut of the plurality of struts such that when the frame is in the radially expanded state, the frame has a substantially elliptical shape.
