A spinal implant comprises a first member defining a longitudinal axis and including a wall that defines an axial cavity and at least one lateral opening configured for disposal of an instrument. A second member is configured for disposal with the axial cavity and includes a wall having an axial surface disposed along a thickness thereof. The axial surface defines at least a portion of an axial opening and includes a plurality of gear teeth disposed therealong. The instrument is engageable with the teeth to axially translate the second member relative to the first member. Systems and methods of use are disclosed.

A method of providing a minimally invasive hip arthroplasty in conjunction with a main incision formed through a patient's skin and soft tissue in the patient's hip, including providing an instrument having a main body and an arrangement for guiding the formation of a portal incision and a small path to the patient's acetabulum along an impaction axis. A trocar is placed through a guide ring on an arm of the instrument to form the portal incision and small path. Impaction of an acetubular shell is carried out along the impaction axis thus formed.

A tibial implant having a stem and a tibial sleeve. The tibial sleeve having a proximal end and a distal end, where the proximal end includes an annular male portion. The tibial implant also includes an offset ring having a central bore that is offset from the center of the offset ring, where the bore of the offset ring receives the annular male portion of the tibial sleeve. The tibial implant further includes a base plate having a proximal end and a distal end, where the distal end of the base plate forms a female portion, and the female portion receives both the offset ring and the male portion of the tibial sleeve.

A stent for transluminal implantation comprises a first, second and third stent section for splinting and/or keeping open a hollow organ which are connected to each other via elastic tubular sections. The stent combines at least three different stent designs in one stent and can therefore be adjusted to the motion behavior of a hollow organ in an improved fashion.

An implant includes a body having a cylindrical portion extending from a first end to a second end, a first nub extending from the first end, and a second nub extending from the second end. The body includes an inner layer, a middle layer, and an outer layer. The inner layer has a first length extending from a tip of the first nub to a tip of the second nub, and has a first central axis collinear with a central longitudinal axis of the implant. The outer layer has a second length extending from the first end to the second end, has a second central axis collinear with the central longitudinal axis, and provides an outer surface of the implant. The middle layer comprises a porous material disposed between the inner layer and the outer layer. The inner layer and at least one portion of the middle layer provide the two nubs.

A stent (10) for transluminal implantation comprises a first, second and third stent section (11, 12, 13) for splinting and/or keeping open a hollow organ which are connected to each other via elastic tubular sections (14, 15). The stent (10) combines at least three different stent designs in one stent and can therefore be adjusted to the motion behavior of a hollow organ in an improved fashion (FIG. 1).

Methods for supporting a prosthetic implant in a patient are disclosed. In some embodiments, a hollow sleeve and a prosthetic implant with a stem component are implanted in a cavity in an end of a bone where the hollow sleeve provides an axial channel that extends through the length of the hollow sleeve for receiving the stem component. In some embodiments, the hollow sleeve is capable of being impacted into the cavity for obtaining a press fit of the hollow sleeve in the cavity. In some embodiments, the hollow sleeve is formed with a porous material.

A joint implant can include a proximal joint implant element having a proximal curved interface surface and a proximal base portion. The joint implant can also include a distal joint implant element coupled to the proximal joint implant element, having a distal curved interface surface facing the proximal curved interface surface, and a distal base portion. A first filament segment and a second filament segment can extend from the proximal joint implant element to the distal joint implant element. The second filament segment can cross the first filament segment at a location between the proximal joint implant element and the distal joint implant element. A proximal bone interface connector can be connected to the proximal base portion, and a distal bone interface connector can be connected to the distal base portion.
