Abstract: A prosthetic heart valve for functionally replacing a previously implanted prosthetic heart valve is disclosed. The prosthetic heart valve includes a collapsible support structure with leaflets and anchors mounted to the support structure. The support structure also includes an inflow end and an outflow end. The anchors include a radially outwardly extending first anchor proximate to the inflow end and a radially outwardly extending second anchor proximate to the outflow end. The first anchor includes a first configuration and the second anchor includes a second configuration where the first configuration is different than the second configuration. The previously implanted prosthetic heart valve serves as a platform for securement of the prosthetic heart valve to the patient's native tissue.

Abstract: A hinged bone screw and tool set is used for implanting such bone screws in a human spine, followed by the implantation of a longitudinal connecting member into the bone screws. The hinged bone screw includes a shank with an upper portion and a receiver with integral arms forming a U-shaped channel. A lower curved seat partially defining the U-shaped channel cooperates with an upper portion of the bone screw shank for hinged movement of the shank with respect to the receiver. The tool set includes an insertion tool, a bone screw driver, a reduction tool and a closure starter. The insertion tool includes a bone screw attachment structure and a laterally opening channel. The insertion tool further includes a threaded portion for cooperation with the reduction tool to provide synchronized placement of a closure structure in the bone screw receiver while reducing and capturing a longitudinal connecting member within the receiver.

Abstract: An orthopedic device for a shoulder joint includes a patient-specific alignment guide. The alignment guide includes a cap having a three-dimensional engagement surface customized in a pre-operative plan by computer imaging to be complementary and closely mate and conform to a humeral head of a proximal humerus of a patient. The alignment guide includes a tubular element extending from the cap and defining a longitudinal guiding bore for guiding an alignment pin at a patient-specific position and orientation determined in the pre-operative plan, and an orientation feature on the cap. The orientation feature is designed to orient the cap relative to the humeral head when the orientation feature is aligned with a landmark of the proximal humerus.

Abstract: A method for treating an intestine with an expandable scaffolding expanded within the intestine. After placing the expandable scaffolding at a target location, such as across a fistula, the first and second end portions of the expandable scaffolding are radially expanded such that the first and second end portions contact an inner surface of the intestine on opposing sides of the fistula, anchoring the first and second end portions to the intestine. Radially expanding the first and second end portions foreshortens the medial portion along the longitudinal axis such that the first and second end portions are drawn closer together along the longitudinal axis as the medial portion foreshortens to close the fistula.

Abstract: Anatomically shaped augments that are configured for implantation in a bone and which have one or more reliefs. A distal end of an outer portion of the augment can have a shape that is configured to generally conform to the shape of a metaphyseal-diaphyseal junction of an intramedullary canal of a bone. A proximal end of the outer portion can have a shape that is configured to generally conform to a shape of the metaphyseal region of the intramedullary canal. The reliefs can be configured to reduce a size of the augment and enhance the degree of freedom in the implant positioning and/or sizing of the augment. Further, such reliefs may contour the augment so as to prevent cortical bone contact and/or prevent contact with the implant device that may be associated with misalignment between an intramedullary canal and metaphyseal or diaphyseal regions of the bone.

Abstract: An orthopaedic surgical instrument includes a patella trial and drill guide that may be used to both perform a surgical trial of the patellofemoral joint and guide the surgeon in drilling a number of anchor holes in the patella of the patient. A method of using such an orthopaedic surgical instrument is also disclosed.

Abstract: A stemless prosthetic shoulder joint may include a prosthetic humeral head and a stemless base. The stemless base may include a collar and an anchor extending from the collar intended to anchor the base into the proximal humerus. The anchor may include various features to enhance the fixation of the base, including hooks, threads, and/or expandable members that may be transitioned from a contracted insertion condition to an expanded implanted condition once the base is positioned in the bone. The anchor and/or collar may also include additional features to enhance fixation, such as geometries and surface features to enhance fixation to bone. The anchor may include a plurality of chisel slots to facilitate removal of bone during a revision surgery.

The haptics engageable with the ciliary sulcus for stabilizing the central lens body at a location posterior, or rearward, of both the lens capsule anterior and posterior portions, such that the central lens body seals the anterior and posterior portions together proximal to a capsulotomy in each of the anterior and posterior portions.

Abstract: A surgical tool for extracting an acetabular ball from an acetabular cup in an implanted hip prosthesis wherein the from acetabular ball is affixed by means of a Morse taper to a stem extending from bottom of the concave portion of the acetabular cup. The surgical tool enables a surgeon to remove the ball without pulling on the acetabular cup and without disrupting any bone ingrowth because the tool maintains pressure on the cup while exerting an opposing pressure pulling on the ball.

Abstract: This invention is the method of treating an ailment associated with the cervical portion of the spine by performing an intravertebral corpectomy that includes the steps of removing the vertebral corpus to define a working channel for the surgeon to gain access to the epidural space so as to attend to and perform a procedure on the pathology. This method obviates the problems incidental to more radical cervical spine operations such as discectomy or corpectomy which requires removal of a portion of the vertebra and adjacent intervertebral discs for decompression of the cervical spinal cord and spinal nerves and using a bone graft with or without a metal plate and screws to reconstruct the spine and provide stability. Prior to terminating the surgery, the opening formed by the removed vertebral corpus is fitted and/or filled with a suitable implant.
