This invention relates to a method for repair of a ligament and/or tendon in a patient comprising applying a patch to said ligament or tendon, wherein the patch is flexible, and bio-compatible and comprises a support layer and a matrix layer.

Method for repair of ligament or tendon

Disclosed is a device and method which provide a surgical therapy for in situ treatment and repair of intra-articular cartilage lesions and/or defects. The device is an implantable laminate cartilage repair patch which is bio-compatible and physiologically absorbable. The cartilage repair patch has a first outer cell occlusive layer; a second outer, cell porous layer adapted to be disposed proximate a subchondral bone wound site; and a cartilagenic matrix disposed between the first and second layers. The cartilagenic matrix is a sink for diffusion of autologous stem cells and includes chemical components promoting generation of hyaline-like cartilage in the presence of the autologous stem cells. The method of the present invention provides the autologous compositions, which when used in combination with the repair patch provides a therapeutic system to regenerate replacement hyaline-like intraarticular cartilage.

In situ system for intra-articular chondral and osseous tissue repair

The present invention relates to wound dressings having a wound contacting layer that contains a wound healing composition and which is adapted to maintain a temperature different from ambient, for example achieve and maintain a heat-absorbing effect on the underlying tissues. The specific physico-chemical structure of the devices of the invention allows fluid containment and absorption of wound secretions while avoiding skin macerations.

Temperature reducing, healing wound dressing

For an endoscopic resection or examination of a body cavity or joint where a physiological liquid is pumped at one location to a joint from a feed conduit connected to a feed pump and withdrawn at another location from the joint through a suction conduit connected to a suction pump, this suction pump is operated at a rate corresponding to a generally constant low rate of flow in the suction conduit and the feed pump is operated in accordance with the pressure detected in the joint to maintain the pressure above a predetermined desired level. Furthermore when a tool carrying one end of an auxiliary suction conduit is inserted into the joint so that periodically this conduit can be connected to the pump so that liquid can be withdrawn from the joint through this auxiliary conduit, the method comprises the step of automatically increasing the suction-pump rate when the auxiliary conduit is connected to the suction pump to a predetermined relatively high rate. When the tool includes a blade and a motor operable to move the blade, the method further comprises the step of automatically disconnecting the suction pump from the main suction conduit and to the auxiliary suction conduit and simultaneously increasing the suction-pump rate from the low rate to the high rate when the motor is operated to move the blade.
