Systems and methods for securing a screen-type active electrode to the distal tip of an electrosurgical device used for selectively applying electrical energy to a target location within or on a patient's body. A securing electrode is disposed through the screen electrode and mechanically joined to an insulative support body while also creating an electrical connection and mechanical enagement with the screen electrode. The electrosurgical device and related methods are provided for resecting, cutting, partially ablating, aspirating or otherwise removing tissue from a target site, and ablating the tissue in situ. The present methods and systems are particularly useful for removing tissue within joints, e.g., synovial tissue, meniscus, articular cartilage and the like.

Abstract of Disclosure A therapeutically effective compound is locally administered by associating the compound with a piece of orthopedic hardware that is implanted at an appropriate site within a body. The compound is adapted, such as through a sustained release device, to administer an effective dosage continuously over an extended period of time. The compound may be administered, for example, to a joint of a mammal by intraarticularly implanting a sustained release device to deliver the therapeutically effective compound within a synovial capsule of the joint, such that synovial fluid concentration of the compound is greater than plasma concentration of the compound. A wide range of orthopedic hardware, such as bone screws and staples, may be adapted to use in the systems described herein to provide treatment for a variety of medical conditions.

Methods and compositions are disclosed for an intra-articular injection for the treatment of osteoarthritis. The methods and compositions comprising combinations of hyaluronic acid and a bone morphogenetic protein, like rhGDF-5, can be useful for any synovial joint, including the knee, shoulder, hip, ankle, hands, spinal facet, or temporomandibular joint, both for the relief of pain and for slowing disease progression.

The invention discloses a silicon micro resonant type pressure sensor and a manufacturing method of the silicon micro resonant type pressure sensor, relates to a pressure sensor and provides a silicon micro resonant type pressure sensor which is based on synovial membrane damping and a double pressure membrane structure, and a manufacturing method of the pressure sensor. The pressure sensor comprises a pressure sensitive layer, a resonant structure layer, a vacuum encapsulation blocking layer and lead electrodes, wherein the upper part of the border frame of the pressure sensitive layer is connected with the lower part of the border frame of a resonant structure layer; the upper border frame of the pressure sensitive layer is internally provided with two pressure membranes and is provided with two cavities for holding parallel silicon islands; the top ends of the silicon islands are connected with a first transmission beam and a second transmission beam on the resonant structure layer; channels are formed between the two cavities, so that the first resonant beam, the second resonant beam, a first mass block and a second mass block on the resonant structure layer have space for free vibration; the upper part of the border frame of the resonant structure layer is connected with a lower border frame of the vacuum encapsulating blocking layer; a cavity is formed inside a lower border frame of the blocking layer; lead holes are formed on the vacuum encapsulating blocking layer; and the lead electrodes are connected with the resonant structure layer through the lead holes.
