At least one of the first gripping element axis of rotation and the second gripping element axis of rotation is variably offset from the arm hinge point by an axis offset distance defined along the longitudinal axis.

Actively controllable stent, stent graft, heart valve and method of controlling same

A delivery apparatus comprises a handle portion and at least one rotatable drive shaft. The handle portion has an actuation mechanism and a display. The actuation mechanism includes a motor and one or more actuators. The rotatable drive shaft has a proximal end portion and a distal end portion. The proximal end portion is coupled to the motor, and the distal end portion is configured to be releasably coupled to a prosthetic heart valve. The actuation mechanism is configured to control and monitor expansion of the prosthetic heart valve, and the display is configured to display a diameter of the prosthetic heart valve.

Reduced profile prosthetic heart valve

A prosthetic heart valve may include a stent body with a plurality of cells arranged in circumferential rows and a cuff attached to the stent. A leaflet attachment panel may be attached to and span a portion of one of the cells. A prosthetic valve element, such as a leaflet having a belly, may be mounted to the leaflet attachment panel. The leaflet attachment panel may not be integral with the stent body. A reduced overlap area may be defined between a proximal end of the stent body and a proximalmost point of attachment of the leaflet belly to the cuff. The reduced overlap area may have a size dependent upon the circumferential row of cells the leaflet attachment panel is attached to and a position of the portion of the leaflet attachment panel to which the leaflet is mounted. Alternately, the leaflet may be attached directly to the stent.

Adjustable prosthetic heart valve

A prosthetic valve including an inner frame, an outer frame, and a connection assembly interconnecting the frames. The inner frame defines an interior volume for receiving a valve structure within the interior volume. The outer frame surrounds the inner frame. The inner and outer frames are each configured to be transitionable between compressed and expanded conditions. The prosthetic heart valve provides a initial deployed state in which the inner and outer frames are in the expanded condition, and a radial shape of the outer frame is adjustable via the connection assembly to a final deployed state. A shape of the outer frame can be adjusted upon implant to enable radial anchoring at the native annulus, while addressing possible non-uniformities of the native annulus and possible anatomical concerns such as LVOT obstruction.

Accommodating intraocular lens (AIOL) assemblies, and discrete components therefor
12036110 · 2024-07-16 · ·

Accommodating intraocular (AIOL) assemblies for enabling post implantation in situ manual selective displacement of an AIOL along a human eye's visual axis relative to stationary anchor points. Axial displacement may be over a continuous range or alternatively at discrete axial stopping positions typically from about 100 ?m to about 300 ?m apart. Novels AIOLs designed to be at least partially folded for facilitating insertion into a human eye through a relatively small incision.

Method and apparatus for fine adjustment of a percutaneous valve structure
10226337 · 2019-03-12 · ·

The invention provides a device for fine adjustment of a prosthetic valve device and a method of adjusting the position of a prosthetic valve after implantation. The adjustment mechanism includes complementary structures on a valve member and device frame that cooperate to provide relative axial and/or angular motion between the valve member and device frame (and thus the native vessel). The adjustment mechanism of the invention may also include a means for selectively maintaining the relative position of the valve member and device frame. The device and method are particularly applicable for use with a modular prosthetic valve device that is assembled in the body lumen.

Adjustable annuloplasty device with alternating peaks and troughs

Apparatus is provided, comprising a ring, comprising a plurality of struts arranged in a pattern of alternating peaks and troughs, each strut having a first end-portion and a second end-portion, each peak defined by convergence of adjacent first end-portions disposed at an angle with respect to each other, and each trough defined by convergence of adjacent second end-portions. The apparatus also comprises a plurality of anchors. Each anchor has a longitudinal axis, is configured to be driven along the longitudinal axis into tissue of the heart, and is coupled to the ring at a respective trough in a manner that facilitates (i) movement of the anchor along the longitudinal axis with respect to the trough, and (ii) deflection of the longitudinal axis with respect to the trough.

Embodiments of the invention relate generally to devices and methods for providing filtration of debris within a body lumen. More particularly, embodiments of the invention related to devices and methods for providing distal protection to a medical procedure by filtration of debris generated by the medical procedure using filters having a frame with a slidable crossover point.

Heat expandable breast implant using induction heating

A selectively expandable breast implant and method for tissue expansion are provided herein. The implant includes a flexible shell, an expandable material inside the flexible shell, and a plurality of closed conducting loops within the expandable material. The closed conducting loops absorb energy from a varying magnetic field external to the implant and generate heat, to heat the surrounding expandable material, and the expandable material expands in size based on the amount of heat generated by the closed conducting loops. The expandable material comprises a plurality of expandable microspheres that expands in response to the heat created by the closed conducting loops. The heat induction mechanism enables the closed conducting loops to generate heat for expansion of the expandable material in the implant. The implant can expand uniformly or in areas designated for selective shaping.
