Abstract:
A transformable stent having an elongated body comprising a proximal end, a distal end, a longitudinal axis, an outer surface, and an inner surface. The inner surface defining a transformable bore extending along the longitudinal axis from the proximal end to the distal end. The transformable bore having a default orientation and a second orientation. The default orientation comprises an open bore defining a longitudinally open channel. The second orientation comprises a closed bore defining a longitudinally closed channel. The transformable stent can optionally include at least two fins that project radially away from the outer surface of the body.
Abstract:
A hybrid prosthetic heart valve configured to replace a native heart valve and having a support frame configured to be expanded post implant in order to receive and/or support an expandable prosthetic heart valve therein (a valve-in-valve procedure). The prosthetic heart valve may be configured to have a generally rigid and/or expansion- resistant configuration when initially implanted to replace a native valve (or other prosthetic heart valve), but to assume a generally expanded form when subjected to an outward force such as that provided by a dilation balloon or other mechanical expander. An inflow stent frame is expandable for anchoring the valve in place, and may have an outflow end that is collapsible for delivery and expandable post-implant to facilitate a valve-in-valve procedure.
Abstract:
An elbow prosthesis constructed in accordance to one example of the present teachings can include a capitellar implant having an articulating head and a stem. The articulating head can have a first articulating surface positioned generally between a lateral side and a medial side. A passage can extend through the articulating head from the lateral side to the medial side. The articulating head can define a counterbore formed at the lateral side and that is concentric with the passage. According to other features, the elbow prosthesis can include a coronoid implant that has a body and a stem. The body can have a superior articulating surface that includes a central ridge and an anterior buttress. The central ridge can be configured to accommodate articulation with a trochlea in an implanted position.
Abstract:
An artificial spinal disk prosthesis comprised of an artificial disk (101) , mounting bracket (105) assembly that secures the disk to at least one vertebrae and a sliding rod (104) that connects the two whereby the shape of the components determines the range of motion of the disk, thus allowing desirable motions of the disk consistent with normal body motions and preventing undesirable motions of the artificial disk. In the preferred embodiment, the angular motion of the disk is controlled by a hinge that is on the side of the artificial disk. In the preferred embodiment, the artificial disc is connected to the spine via one vertebra.
Abstract:
A device for treating a heart may comprise a myocardial section configured to be positioned in a heart wall between a coronary vessel and a chamber of the heart and a vessel section configured to be positioned in the coronary vessel. The vessel section may be connected to the myocardial section and be configured to articulate relative to the myocardial section. The myocardial section and the vessel section may form an integral, single piece structure.
Abstract:
The invention relates to a spinal implant to be inserted between two vertebra to support and stabilize adjacent vertebra and allow for physiological motion. The invention includes an implantable device to support the vertebrae, and a minimally invasive method for inserting and deploying the device within the intervertebral space.
Abstract:
A connecting device for use in attaching together at least two adjacent vertebrae comprises upper and lower plate members (202, 204) adapted to be fixedly secured respectively to adjacent upper and lower vertebrae via fasteners, e.g. screws (200). The upper and lower plate members are provided with respective male and female guide elements (210, 222) that are slidable engaged together so as to allow a relative translational displacement between the upper and lower plate members in response to a similar relative displacement between the upper and lower vertebrae that alters a spacing therebetween. A method includes removing at least part of a disc from an intervertebral space defined between a pair of adjacent vertebrae that include upper and lower vertebrae and securing first and second plate members respectively to the upper and lower vertebrae, said plate members being capable of relatively displacing for accommodating a change in a distance between the upper and lower vertebrae; wherein a bone graft is positioned in the intervertebral space.
Abstract:
Resilient surgical meshes that, in some aspects, can be compressed or otherwise configured, for minimally invasive delivery in the intervertebral discs are provided. According to one or more embodiments, the surgical mesh can be robust, fatigue resistant, stable and capable of withstanding the dynamic environment generic to intervertebral discs.

Abstract:
A prosthetic device (410) for transforaminal insertion into an intervertebral space is provided. The prosthetic device includes a first component (412) having a first curved flange (426) for engaging a first vertebra from a transforaminal approach, the first component having a first articular surface (418), and a second component (414) having a second curved flange (450) for engaging a second vertebra from a transforaminal approach, the second component having a second articular surface (432) for cooperating with the first articular surface to permit articulating motion between the first and second components.
