    Abstract: A drive unit for a micro valve comprises a housing, a spring and at least one shape memory alloy element which is attached to the housing in a deflectable manner. The shape memory alloy element is loaded by the spring towards a deflected position and is movable in response to a temperature increase and the shape memory effect activated thereby, into a position which is at least less deflected against an increasing load by the spring. A normally closed micro valve includes a fluid housing, at least one valve seat, a sealing element opposite the valve seat, and a drive unit of the type mentioned above. The shape memory alloy element cooperates with the sealing element and exerts an operating force on the sealing element for closing and opening the valve seat with or against a compression spring force.

    Abstract: A tissue-separating catheter assembly comprises a rotatable shaft, having a distal shaft portion, and a tissue separator device extending along the shaft. The tissue separator device has a distal separator part at the distal shaft portion movable between a retracted state, towards the distal shaft portion, and an outwardly extending, operational state, away from the distal shaft portion. A pivot joint may be used to pivotally connect the distal separator end to the distal shaft portion. The distal shaft portion may comprise a distally-facing transition surface at a proximal end of the distal shaft portion. First and second energizable tissue separator elements may be used at the transition surface and the tip of the device, respectively.

    Abstract: An endoscopic electrosurgical instrument is presented for encapsulating and resecting biologic tissue, such as a polyp, from an anatomical structure, such as a lumen. The instrument includes an encapsulation assembly which includes a snare coupled to an electrically non-conductive, shrinkable pouch in a drawstring-like configuration. The encapsulation assembly may be folded within the elongated cylindrical housing of the endoscopic instrument, positioned within the patient at the surgical site, and deployed for use. Once positioned over the polyp, the snare is tightened around the peduncle thereof, and the pouch is activated, thereby shrinking and encapsulating the polyp. The polyp may then be resected using conventional or electrosurgical techniques. The disclosed instrument may include surgical tools and/or electrosurgical electrodes for performing surgical procedures. The disclosed system may reduce the occurrence of undesirable arcing and may aid retrieval of resected tissue.
