Implant apparatus and methods are directed toward treating conditions involving the knee joint, and the patella specifically, maintain alignment or address misalignment of a patella through a full range of motion of the knee joint Exemplary devices include an elastomeric, Y-shaped device which is secured to the femur and patella on opposite ends thereof by bone anchors. The elastomeric device can be either rotatably or non-rotatably connected to the bone anchors.

Structures for treating patello-femoral osteoarthritis

An apparatus and related method for controlling a load on a human ankle joint during normal gait while preserving motion. The approach is intended to treat osteoarthritis and pain of the ankle without substantially resisting an angular displacement associated with full mobility of the ankle joint. In one particular embodiment, the device includes a first load transmission support, a second load transmission support and an implantable compressible absorber.

Implantable device for relieving ankle pain

A luminal prosthesis comprises a plurality of radially expandable prosthetic stent segments arranged axially. Two or more of the prosthetic stent segments are separable upon expansion from the remaining prosthetic stent segments and a coupling structure connects at least some of the adjacent prosthetic stent segments to each other. The coupling structure permits a first group of the adjacent prosthetic stent segments to separate from a second group of the prosthetic stent segments upon differential radial expansion of the first group relative to the second group and the coupling structure maintains or forms an attachment between the adjacent prosthetic stent segments in the first group which have been expanded together. A delivery system and methods for deploying the multiple coupled prosthetic stent segments are also disclosed.

Apparatus and methods for deployment of linked prosthetic segments

Implant apparatus and methods directed toward treating conditions involving the knee joint and the patella specifically are disclosed. Full range of motion of the knee joint and tissue integrity are maintained in treatment approaches involving implanting a joint surface load reducing implant proximate the joint to change the direction of the tendons or muscles exerting forces on the joints.

Methods of redistributing forces for the patella with spacers

A system for manipulating energy transferred by members defining a joint and a method of implantation includes a first attachment structure configured to be attached to a first member of the joint and a second attachment structure configured to be attached to a second member of the joint.

Implantation approach and instrumentality for an energy absorbing system

Positioning instruments and related methods are described for implanting an energy absorbing system for treating joints. The positioning instruments and methods allow the energy absorbing system to be positioned at a joint such that the desired motion will occur for the particular design of a particular energy absorbing system which is to be implanted. The positioning instruments include a locating instrument for locating an anatomical feature and a target location for implantation of the energy absorbing system, a verification instrument for verification of the target location, a placement guide for guiding placement of a part of the energy absorbing system, and positioning device for aligning portions of the energy absorbing system.

Spacers for redistributing forces for the patella

A tubular prosthesis has a plurality of tubular rings that are radially expandable from a contracted configuration to an expanded configuration. Each ring comprises a plurality of axially oriented struts that are interconnected so as to form a circumferential series of at least one high peak and at least one low peak. The high and low peaks have apices that are oriented in the same axial direction. The apices of the high and low peaks are also oriented in the same direction and the apices of the high peaks are axially offset from the apices of the low peaks. A bridge member couples a pair of adjacent tubular rings together. The bridge member has a first end connected to a first low peak in a first tubular ring and a second end connected to either a high or low peak in an adjacent tubular ring.

Apparatus having variable strut length and methods of use

An apparatus and related method for controlling a load on a human hip joint during normal gait while preserving motion. The approach is intended to treat osteoarthritis of the hip without substantially resisting an angular displacement associated with full mobility of the pelvis and femur bones.

A stent crimping assembly is provided for crimping a stent from a first diameter to a reduced second diameter. The crimping assembly includes a plurality of movable wedges disposed about a rotational axis to form a wedge assembly. Each wedge includes a respective first side and a second side converging to form a tip portion. The tip portions are arranged to collectively form an iris about the rotational axis thereof. The iris defines a crimp aperture about which the movable wedges are disposed. A control unit is electronically programmed to control the mechanical components. A method of calibrating the control unit includes inserting a quill of known diameter into the iris and reducing the diameter of the iris onto the quill.

Stent crimping system and method

A stent crimping assembly is provided for crimping a stent from a first diameter to a reduced second diameter. The crimping assembly includes a plurality of movable wedges disposed about a rotational axis to form a wedge assembly. Each wedge includes a respective first side and a second side converging to form a tip portion. The tip portions are arranged to collectively form an iris about the rotational axis thereof. The iris defining a crimp aperture about which the movable wedges are disposed. Each wedge is associated with a stationary structure and an rotational actuation unit such that during rotation of the actuation unit about the rotational axis, the iris is caused to rotate about the rotational axis, relative the stationary structure, for inward movement of the wedges to decrease the size of the aperture and outward movement of the wedges to increase the size of the aperture.

Endoprosthesis, such as a stent, includes at least one annular element defined by a first set of strut members interconnected to define apices proximate opposite sides of the annular element. The annular element further includes a foot extension extending between at least one pair of circumferentially-adjacent strut members. The foot extension has first and second foot portions extending circumferentially from corresponding ends of the circumferentially-adjacent strut members, and are contoured to provide at least two areas of flexure. The first and second foot portions are joined at a toe portion of the foot extension, and define a circumferentially-directed apex between the pair of circumferentially-adjacent strut members. Preferably, at least one or more additional annular elements, each defined by interconnected strut members, are provided. The annular elements are generally expandable between a delivery configuration and a deployed configuration. The annular elements are longitudinally aligned and connected at connection locations. Preferably, each connection location includes a foot extension, such as by an overlapping pattern between the longitudinally-adjacent annular elements or by a connector extending therebetween.

Endoprosthesis having foot extensions

A stent crimping apparatus is provided which includes a crimping assembly adapted to crimp the stent, a clamp assembly configured to secure the medical device; and a control unit configured to control the movement of the crimp assembly. The clamp assembly includes a lower clamp device defining a seating groove formed and dimensioned to seat a portion of the medical device therein, and a retaining assembly having an elastomeric member. This elastomeric member defines a contacting groove oriented in an opposed manner proximate to at least a portion of the seating groove. The clamp assembly further includes an actuation mechanism associated with the retaining assembly and the lower clamp device such that operation thereof causes the retaining assembly to move between an opened condition and a closed condition. In the opened condition, the medical device can be positioned between the lower clamp device and the retaining assembly, and in the closed condition, retaining the medical device between the contacting groove of the elastomeric member and the seating groove of the lower clamp device.
