Abstract:
A vertebral rod includes a first elongated section defining a first thickness. A second elongated section defines a second thickness. An intermediate section is disposed between the first section and the second section and defines a third thickness. The third thickness has a dimension being less than a dimension of at least one of the first thickness and the second thickness. The intermediate section has an inner surface that defines an open end. A resistance member has an exterior surface configured for engaging at least a portion of the inner surface.
Abstract:
Mixing systems for storing and mixing multiple components of various medical compositions are provided. Generally, the instant mixing systems comprise a barrel, a plunger slidably disposed inside a barrel, and a pushing rod slidably disposed inside the plunger. The instant mixing system may further comprise multiple chambers for storing individual components or mixtures of components, with at least one chamber disposed in the barrel and at least one chamber disposed inside the plunger.
Abstract:
A stabilizing system (10) for stabilizing a patient's spinal column comprises a flexible implant (20) configured for attachment to a vertebral member, an anchor plate (30) for attaching the flexible implant to the vertebral member, and at least one fastener (50) to secure the anchor plate to the vertebral member. The anchoring plate has a bottom surface with one or more projections (36) configured to penetrate the top surface of the flexible implant when a clamping force is applied.
Abstract:
Orthopedic implants (100, 200, 300, 301, 320, 340, 400, 500, 600, 700, 720, 740, 760, 770, 800, 900, 1000, 1100, 1200, 1300, 1400, 1500, 1600, 1700, 1800) include a device that is non-rigid, i.e., flexible and/or malleable, in a first form for insertion into a desired in vivo site, and then transformable into a rigid, or hardened, form for providing a load-bearing function or providing other structural and/or mechanical function after implantation. The device includes a biocompatible sheath (110) and a curable material (120) sealed within the sheath (110). The curable material (120) is provided in a first form that provides flexibility to the device and is structured to rigidize in a second form after application of a quantity of an initiating energy to the material (120). Related methods and kits are also provided.
Abstract:
An implant is disclosed and can include a body and a plurality of pellets disposed within the body. The implant can be moved between an unmolded, relaxed configuration wherein the body is not conformed to a bone and a molded, relaxed configuration wherein the body is at least partially conformed to the bone.
Abstract:
The invention provides devices and related methods and composition useful for diagnosis and monitoring the pain generator(s) of axial pain with or without radiculopathy and methods for screening test compounds potentially useful for treating axial pain with or without radiculopathy. Alternatively, degenerated discs can be monitored and treated before occurrence of a pathological pain condition. Pain markers and markers of degenerating disc include markers of neuronal, vascular, immune and matrix elements.

Abstract:
A multi-chamber expandable interspinous process brace (400) is disclosed and can include at least two chambers (402, 404). Each of the at least two chambers can receive an injectable biocompatible material. Further, the multi-chamber expandable interspinous process brace can be moved between a deflated configuration and an inflated configuration. In the inflated configuration, the multi-chamber expandable interspinous process brace can engage and support a superior spinous process and an inferior spinous process.
Abstract:
A surgical implantation procedure and device according to which an expandable member is inserted between anatomical structures, and is expanded into engagement with the structures. The expansion is terminated when the member is in engagement with the structures.
Abstract:
A system for implanting an interspinous process spacer (30) comprises a deformation instrument (42) adapted to engage a pair of opposing arms (34, 36, 38, 40) of the interspinous process spacer and operable to move the opposing arms relative to one another to deform the interspinous process spacer from an uncollapsed state to a collapsed state. The system further comprises a cannula (58) adapted to receive the collapsed interspinous process spacer from the deformation instrument and direct the interspinous process spacer to an area between a pair of spinous processes.
