A mesh implant and/or container may be used as an intervertebral implant. The mesh implant may be anchored or otherwise fixed to the vertebral endplates to prevent the implant from migrating forward and out anteriorly to the spinal column. The mesh implant may be knitted with a rip stop, elastic or other stich pattern to prevent unraveling or tearing.

A rotator cuff balloon (10) includes a limiting structure (100) and a protective structure (200) connected to the limiting structure (100). The limiting structure (100) has a curvature along a coronal plane (102). This rotator cuff balloon (10) conforms to the physiological structure of the shoulder joint in the human body, limits itself in the subacromial space and can reduce a patient's foreign body sensation, dislocation, functional failure and other adverse events. The protective structure (200) is configured to be supported in the space between the humeral head and the acromion of the shoulder joint in the human body to provide support. Moreover, the humeral head of a patient with a rotator cuff injury is raised, avoiding pain arising from inter-tissue collisions, increasing the moment arm of the deltoid muscle and resulting in immediate improvements in the functions of the patient's shoulder joint. The limiting structure (100) is configured to fit against at least part of the humeral head of the shoulder joint in the human body, thus providing a position-limiting effect and avoiding displacement of the prosthesis.

Implants are provided. In one exemplary embodiment, an implant includes a spacer configured to be implanted within a joint. The spacer includes an elongated central body extending from a first end to a second end with a longitudinal axis extending therebetween, and first and second wings extending from the first and second ends of the elongated central body, respectively. The elongated central body has a first maximum height in a direction transverse to the longitudinal axis, and each of the first and second wings has a maximum height greater than the first maximum height. When implanted and in the inflated state, at least one of the first wing and the second wing is configured to mechanically interlock with a portion of the anatomy to thereby self-anchor the spacer to the joint and inhibit migration of the spacer. Implant systems and methods for biomechanically augmenting muscle function are also provided.

A device including a delivery port and a method of delivering a material via a delivery port is disclosed. The device includes a body extending between a proximal surface and a distal surface. The body is sized and configured to be coupled to an anatomical structure at an implantation site. A first inlet port is formed in a distal surface of the body and is sized and configured to receive a first material. A first outlet port is formed in the proximal surface of the body. The first outlet port is coupled to the first inlet port by a first fluid path defined by the body and the first outlet port is sized and configured to provide the first material to a first predetermined location when the body is coupled to the anatomical structure.

A prosthesis for implantation in a de-nucleated intervertebral disc includes a fiber ring-like layer which encloses a polymeric layer to create an annular space. The annular space is inflatable with an in-situ curable liquid polymer and forms an interior cavity. The annular space may be expanded uniformly or differentially to be tailored to the needs of a particular vertebral segment and to achieve optimal disc space width and angle, thereby stabilizing the segment while preserving normal motion of the vertebral segment. The interior cavity provides a void that allows inward deformation of the implant during weight bearing activities and bending. The prosthesis can be elastically deformed through axial elongation to a reduced profile to load into a delivery cannula using pulling techniques.

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 invention 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.

A hybrid spinal implant for performing an intervertebral fusion procedure can include a pair of spacers separated by an expandable container that are formed of a porous titanium scaffold material. A connecting rod can span longitudinally between the pair of spacers. The spacers can be formed of titanium or PEEK, with endplates that are formed of the porous titanium scaffold material. The endplates can be bioactive. Exposed surfaces of the porous titanium scaffold material can be coated in a snag-preventing substance. The expandable container can be formed of a mesh material.

An expanding, conforming interbody implant includes a plurality of superior and a plurality of inferior segments. The segments are adapted to individually expand, contact, and conform to endplates of vertebral bodies to distribute forces equally over the implant and across the vertebral endplates. Once a proper extension of the segments has been achieved, the segments are locked in position. The implant has a stiffness that approximates the stiffness of bone, and the implant minimizes problems with subsidence, endplate fractures, and stress shielding.

Provided herein are compositions and medical devices, and in particular, biodegradable scaffolds capable of repairing and replacing cartilagenous meniscuses. Also provided herein are methods of using scaffolds for treating degenerative tissue disorders. In certain embodiments, such scaffolds can promote tissue regeneration of a temporal mandibular joint (TMJ) meniscus.

Apparatus and methods for treating a spinal body having an interior. The method may include augmenting a height of the spinal body by radially expanding a first mesh cage in the interior. The method may include removing the first cage from the interior. The method may include supporting the spinal body in an elevated position by radially expanding a second mesh cage in the interior. The method may also include surgically enclosing the second cage in the interior.
