An implant system for implantation at a joint, the implant system including an implant device, the implant device comprising a body portion having first and second ends, and a first elongate member, extending from the first or second end of the body portion, the first elongate member being insertable in a bone tunnel in a subject's tibia.

A balloon implantation kit includes an inflatable biodegradable balloon configured to be implanted in a human body and a hydrogel composition. In some cases, the hydrogel composition is provided in a container configured to be introduced into the biodegradable balloon. For some applications, the biodegradable balloon includes a joint spacer for treatment of a joint of a human subject, such as a subacromial spacer, a glenohumeral spacer, or a spacer for another joint, such as a knee, hip, ankle, or hand (e.g., CMC1) joint. In these applications, the biodegradable balloon is configured to be inserted into a space of a joint of the human body, and is shaped to provide mechanical support to the joint until the biodegradable balloon resorbs into the human body. For other applications, the biodegradable balloon includes a soft tissue spacer.

A lubrication device for lubricating a joint of a human or mammal patient, which is entirely implantable in a patient's body, comprises a reservoir for storing a lubricating fluid and a fluid connection for introducing the lubricating fluid into the joint when the device is implanted in the patient's body. Further, the fluid connection comprises a fluid connection device connecting the reservoir with the joint such that a lubricating fluid flow is established from the reservoir into the joint. The fluid connection comprises either an infusion needle adapted to be intermittently placed into the joint for injecting the lubricating fluid, or a tube adapted to be permanently placed into the joint for continuously injecting the lubricating fluid.

A method for treating joint pain in a subject is disclosed. The method can include inserting a bone dowel and a first portion of a bone marrow aspirate into a subchondral region of a bone that is part of a joint being treated and introducing a second portion of the bone marrow aspirate into the intraarticular space of the joint being treated.

Expandable prosthetic devices used for treating a variety of conditions, including rotator cuff injuries, broken and/or depressed bone fractures, infection and/or inflammation in the body. In one embodiment, a prosthesis includes an implant having a pressure regulating valve. The implant is capable of being positioned between a first tissue and an opposing second tissue in a void space and of deforming under pressure in response to articulation of a joint. The pressure regulating valve is configured to open based on a predetermined pressure in the implant.

A bone positioning guide may include a main body member, a shaft, and a bone engagement member. The shaft can be movably connected to the main body member and have the bone engagement member rotatably coupled to its distal end. The bone engagement member can have a surface configured to engage a bone. The main body member can also include a tip opposite the bone engagement member for engaging a second bone. In use, the bone engagement member may be positioned in contact with a medial side of a first metatarsal while the tip is positioned in contact with a lateral side of a different metatarsal, such as a second metatarsal. The shaft can then be moved to advance the bone engagement member toward the tip, causing realignment of the first metatarsal.

A method for ameliorating joint conditions and diseases and preventing bone hypertrophy can include facilitating cartilage regrowth and preventing bone overgrowth to a damaged bone at a treatment site within a body joint to promote healing. The method can include providing a device having a first section comprising a joint-ward end having an inner surface and an outer surface and fenestrations between the inner and outer surfaces. A second section can include an opposing leading end and a lateral wall extending between the joint-ward end and the leading end. The leading end can be penetrated into the bone to a depth to substantially position: 1) the joint-ward end in a cartilage zone or at a boundary/transition area; and 2) the second section in the bone. Bone overgrowth into the cartilage zone may be prevented within the body joint when the device is positioned at the treatment site.
