A device for performing a surgical procedure on a knee comprises a femoral assembly comprising a stationary femoral member attachable to the distal femur, an adjustable femoral member movably coupled with the stationary member to adjust tension in at least one ligament of or adjacent the knee and an adjustment mechanism coupled to the assembly. The adjustable member includes at least one positioning feature that moves relative to the distal femur as the adjustable member is adjusted and identifies at least one position on the distal femur. The adjustable member is movably couplable with a tibial member engaged with a proximal tibia to allow the knee to be moved through a range of motion without removing the femoral and tibial members. The mechanism includes an actuator positioned proximate a medial or lateral portion of the adjustable member. The actuator is configured to adjust an opposite portion of the adjustable member.

A two-part accommodating intraocular lens (IOL) device for implantation in a capsular bag of a patient's eye. The IOL device includes a primary lens assembly and a power changing lens. The primary lens assembly includes a fixed lens and a peripherally disposed centration member. The centration member has a circumferential distal edge and a first coupling surface adjacent the circumferential distal edge. The power changing lens has an enclosed, fluid- or gel-filled lens cavity and haptic system disposed peripherally of the lens cavity. The haptic system has a peripheral engaging edge configured to contact the capsular bag and a second coupling surface. The first and second coupling surfaces are in sliding contact with one another to permit movement of the power changing lens relative to the primary lens assembly and also to maintain a spaced relationship between the fixed lens and the lens cavity during radial compression of the power changing lens.

The present invention provides a device for identifying a tumor site in a subject, the device spectroscopically detecting fluorescence of protoporphyrins present in the tumor site,the protoporphyrins being protoporphyrin IX (PpIX) and photo-protoporphyrin (PPp), andthe device comprising:a light irradiation unit that converts part of PpIX into PPp;a spectroscopy unit that separates PpIX fluorescence and PPp fluorescence:a spectroscopy detection unit that detects the relative fluorescence intensity of the PpIX fluorescence and the PPp fluorescence; anda tumor discrimination unit that discriminates between the tumor site and a non-tumor site based on the relative fluorescence intensity of PpIX and PPp.

Fastening devices are provided that are designed to effectively close tissue as well as instruments for applying the inventive fastening devices. The devices are useful for closing tissue such as mucosa in the oral cavity, oropharynx, hypopharynx, laryngeal surfaces, oronasopharynx, or other mucosal tissues. In particular, uvulopalatopharyngoplasty (UPPP), uvulopalatal flap (UPF) technique, and tonsillectomy can be assisted using the inventive system. Embodiments also provide methods of using the fastening devices and / or instruments, and kits including the fastening devices.

The present invention relates to a fat removal device, which comprises: a navigation system having a first connection end and a first terminal; a hollow suction tube having a second connection end and a second terminal, wherein the navigation system is disposed inside the hollow suction tube; a connection unit connected to the first connection end and the second connection end; a robotic arm connected to the connection unit to rotate and move the connection unit multidirectionally; a suction unit connected to the connection unit by a pipeline between the connection unit and the suction unit; and a microprocessor connected to the connection unit, the robotic arm, and the suction unit, to transmit signals from one to another.

Provided herein are compositions and methods for treating a subject with damaged tissue, such as an injury associated with a tissue to tissue (e.g., a connective tissue-to-connective tissue or tissue to bone) interface. One aspect provides an adhesive film or adhesive layer, optionally comprising a biomaterial, tissue growth factors, including CTGF / CCN2, or cells.

It has been discovered that the 2-carbon-modified derivatives of 1α,25-dihydroxyvitamin D3 specifically stimulate osteoblasts to form new bone. The ability of the 2-carbon-modified vitamin D analogs to stimulate new bone formation suggest that these compounds can be used where synthesis of new bone is required. Thus, these compounds can be used either systemically or locally to stimulate the growth of bone transplants, to increase the rate of fracture healing and thereby reduce the time required for the healing of fractures, the stimulation of bone growth when required for replacement surgery, and also for the growth of bone to implants or other devices required to maintain the skeleton or teeth in the proper positions.

A marking / drying tool applies ink to biological tissue using a single handheld device. A cylindrical body retains a felt tip movable between a retracted position within the body and an extended position outside the body for marking the tissue. A gas source has a manual valve to selectably dispensing a drying gas onto the tissue. In a preferred embodiment, an interlock prevents dispensing of drying gas when the tip is in the extended position and prevents the tip moving to the extended position when the manual valve is dispensing the drying gas.
