Abstract: Methods, systems, and devices are described for mapping and treating tissue during a medical procedure. In some cases, a device includes a mesh of wires with sensors coupled thereto. The device can be coupled to an expandable treatment element. The expandable treatment element can include multiple segments. The sensors can be used to map a tissue area and monitor the tissue during a medical procedure.

Abstract: Implementations described herein are directed toward an improved orthopedic arthroscopy system that reduces the number of necessary arthroscopic portals while at the same time improving endoscopic visualization and instrumentation capability within the joint space. Main embodiments of the disclosed system replace the traditional rod endoscope with a rotatable, optical cannula through which instruments can be used to manipulate tissue and perform surgery. By adding the cannula rotation capability, visualization of instrument tool tip can be easily adjusted. The disclosed system would eliminate the need for unnecessary wrist rotation by the surgeon thereby making it easier to coordinate hand position while performing surgical tasks.

Abstract: An intraluminal, balloon expandable stent for implantation in a body lumen is disclosed. The present invention provides a lumen support stent with an unobstructed through-lumen for use in a blood vessel. A constraining mechanism is provided for securely maintaining the stent in the collapsed condition during delivery. The stent is preferably formed with a series of interconnected slide and lock mechanisms for permitting movement from a collapsed condition to an expanded condition and inhibiting radial recoil from the expanded condition. The stent may be formed from a shape memory alloy for providing crush-recovery after deployment.
