CATHETER WITH INTEGRATED EMBOLIC PROTECTION DEVICE
A prosthetic heart valve delivery catheter includes an embolic filter to provide integrated embolic protection to inhibit the release of emboli into the aorta, the aortic arch or branch vessels, and other vasculature during transvascular heart valve replacement procedures. The embolic filter will usually be fixedly or movably attached to a shaft of the delivery catheter proximal of the prosthetic heart valve.
Implantable heart valve devices, mitral valve repair devices and associated systems and methods
Systems, devices and methods for repairing a native heart valve. In one embodiment, a repair device for repairing a native mitral valve having an anterior leaflet and a posterior leaflet between a left atrium and a left ventricle comprises a support having a contracted configuration and an extended configuration. In the contracted configuration, the support is sized to be inserted under the posterior leaflet between a wall of the left ventricle and chordae tendineae. In the extended configuration, the support is configured to project anteriorly with respect to a posterior wall of the left ventricle by a distance sufficient to position at least a portion of the posterior leaflet toward the anterior leaflet.
Replacement heart valve systems and methods
Systems and methods for replacing a native heart valve. An anchor comprises multiple coils adapted to support a heart valve prosthesis. At least one of the coils is normally at a first diameter, and is expandable to a second, larger diameter upon application of radial outward force from within the anchor. An expansible heart valve prosthesis is provided and is configured to be delivered into the anchor and expanded inside the multiple coils. This moves at least one coil from the first diameter to the second diameter while securing the anchor and the heart valve prosthesis relative to each other. The system further includes a seal on the anchor that can prevent at least some blood leakage after implantation of the heart valve prosthesis in the helical anchor. Additional apparatus and methods are disclosed.
DEFORMABLE TIP FOR STENT DELIVERY AND METHODS OF USE
A stent-delivery assembly that includes a catheter; an expandable stent that is movable, relative to the catheter, from a first position to a second position; and a guidewire assembly extending through a longitudinal passage of the catheter and a longitudinal passage of the stent, the guidewire assembly being movable, relative to the catheter, from a third position to a fourth position. While the expandable stent is in the first position and while the guidewire assembly is in the third position, the stent-delivery assembly has an a-traumatic shape. While the expandable stent is in the second position and while the guidewire assembly is in the fourth position, the guidewire assembly is capable of passing through the stent to allow for retrieval of the stent-delivery assembly. Methods of use and manufacture are also included.
Heart valve sealing devices and delivery devices therefor
An implantable prosthetic device includes a coaption portion, paddles, and clasps. The paddles are moveable from a closed position to an open position. The clasps are also moveable from an open position to a closed position. The implantable prosthetic device can be used to repair a native valve, such as a native mitral valve. Other embodiments are also described.
Wire annuloplasty ring
The disclosure describes an annuloplasty device that includes a wire configured to extend around at least part of an annulus of a cardiac or vascular valve, such as at least partially around a circumference of the annulus, and a plurality of anchors. The anchors of the plurality of anchors are configured to engage the wire and anchor the wire to the annulus. The wire is configured to urge at least some anchors of the plurality of anchors toward each other in a radially inward direction to decrease a distance between valve leaflets that extend from the annulus.
Expandable support device and method of use
An expandable support device for tissue repair is disclosed. The device can be used to repair hard or soft tissue, such as bone or vertebral discs. The device can have multiple flat sides that remain flat during expansion. A method of repairing tissue is also disclosed. Devices and methods for adjusting (e.g., removing, repositioning, resizing) deployed orthopedic expandable support devices are also disclosed. The expandable support devices can be engaged by an engagement device. The engagement device can longitudinally expand the expandable support device. The expandable support device can be longitudinally expanded until the expandable support device is substantially in a pre-deployed configuration. The expandable support device can be then be physically translated and/or rotated.
Graft fixation
The present disclosure relates to an anchor for fixating a tissue graft to bone. The anchor includes a through hole extending an entire length of the anchor and a polymer composition having shape memory qualities. Other anchors and methods for fixating a tissue graft to bone are also disclosed.
Accommodating intraocular lens having dual shape memory optical elements
An accommodating intraocular lens (AIOL) for implantation in a human eye includes a housing including an anterior member with a leading surface, a posterior member with a trailing surface, a leading shape memory optical element adjacent the anterior member and resiliently elastically deformable between a non-compressed shape in a non-compressed state of the AIOL and a compressed shape in a compressed state of the AIOL, and a trailing shape memory optical element adjacent the posterior member and elastically deformable between a non-compressed shape in the AIOL's non-compressed state and a compressed shape in the AIOL's compressed state for selectively bulging into the leading shape memory optical element on application of a compression force the said longitudinal axis against the trailing surface from a posterior direction for modifying the shape of the leading shape memory optical element with respect to its non-compressed shape in the AIOL's the non-compressed state.
Inter-body implantation system and method
A system for implanting an inter-body device between adjacent vertebrae comprises an inter-body device having a plurality of cans secured to a flexible bridge and having a relief portion therebetween. An inserter tube and complementary bullnoses are advantageously secured to the vertebrae by an extension arm for securing the assembly precisely in place. A plurality of articulating trial implants are provided to test fit a disc space for the proper sized inter-body device.
