A method includes: making a first incision in a patient defining a first lateral direction to a first lateral side of the patient's spine; inserting an intervertebral prosthesis through the first incision and into an intervertebral space of the spine in the first lateral direction; locating the intervertebral prosthesis between an endplate of a first vertebral bone of a spine, and an endplate of an adjacent, second vertebral bone of the spine; closing the first incision; making a second incision in the patient defining a second lateral direction to a second lateral side of the patient's spine, opposite to the first direction and the first lateral side; reversing the locating of the intervertebral prosthesis from the endplate of the first vertebral bone of the spine, and from the endplate of the adjacent, second vertebral bone of the spine; removing the intervertebral prosthesis from the intervertebral space of the spine from the second lateral direction and out through the second incision; and closing the second incision.

Embodiments of the present disclosure relate to devices and methods for treating one or more damaged, diseased, or traumatized portions of the spine, including intervertebral discs, to reduce or eliminate associated back pain. In one or more embodiments, the present disclosure relates to an expandable interbody spacer. The expandable interbody spacer may comprise a first jointed arm comprising a plurality of links pivotally coupled end to end. The expandable interbody spacer further may comprise a second jointed arm comprising a plurality of links pivotally coupled end to end. The first jointed arm and the second jointed arm may be interconnected at a proximal end of the expandable interbody spacer. The first jointed arm and the second jointed arm may be interconnected at a distal end of the expandable interbody spacer.

This disclosure provides for a medical device to be implanted in the vasculature and a method for treatment in the vasculature. The device has an outer layer of a first material and an inner layer of a second material attached to the outer layer. The inner layer further has a plurality of elastomeric tensioners. If the device experiences relaxation, resulting in a decreased radial force against the vessel wall, the elastomeric tensioners may provide a contraction force to the inner layer and the outer layer, resulting in a maintained radial force on the vessel wall.

An expandable cage (1) for maintaining a distance between two vertebras on a spine and providing fusion is disclosed. The expandable cage (1) comprises a horizontal axis, a front part with an upper arm (1.1), a lower arm (1.2), and shaft fixation sockets (1.7.1 and 1.7.2) located between the arms (1.1 and 1.2), and a hollow shaft (2) with graft holes (2.4). The shaft (2) is placed parallel to the horizontal axis and partially inside the shaft fixation sockets (1.7.1 and 1.7.2). The cage (1) is expanded vertically by rotating the shaft (2) 90 degrees with an instrument, thus further separating vertically the upper arm (1.1) and the lower arm (1.2).

An intervertebral prosthesis includes: a body; a first aperture extending from within the body and opening; a first anchoring element disposed within the first aperture and including a shaft having proximal and distal ends, where the proximal end of the first anchoring element includes a first portion of a first articulation mechanism; and a drive mechanism having: (i) a threaded shaft defining a longitudinal axis thereof and a head at a proximal end of the threaded shaft, (ii) a translator element having a threaded bore in threaded engagement with the threaded shaft.

The embodiments of the present disclosure relate to a spinal implant assembly having features to prevent or minimize fixation elements, such as screws, from being dislodged, or from backing out over time and with use. The spinal implant assembly may comprise an implantable body having first apertures for receiving fixation elements. A plate configured to nest against the posterior portion of the implantable body and comprising one or more second apertures can be provided. These second apertures permit access to the head portions of the fixation elements. One or more locking elements are then passed through the second apertures and engage the head portions of the fixation elements. In addition, the plate may comprise an adjustable arm to allow the plate to be used with implantable bodies of different size.

An implantable prosthesis for repairing tissue defects includes a layer of repair fabric and a plurality of microtextured grip segments mounted to the repair fabric. The grip segments include a pattern of perforations on a tissue facing surface to promote tissue ingrowth.

A method for assembling a prosthetic heart valve can include forming a leaflet assembly from a plurality of leaflets. Each leaflet can include opposing commissure tabs. The leaflet assembly can be formed by pairing a commissure tab of each leaflet with an adjacent commissure tab of an adjacent leaflet and connecting each pair of commissure tabs to a commissure support member to form a respective commissure assembly of the leaflet assembly. The method can further include positioning the leaflet assembly within an interior of an expandable annular frame. The frame can define a plurality of openings. The method can further include inserting each of the commissure assemblies through a respective opening of the frame so as to position the commissure assemblies on an exterior of the frame.
