摘要： The present invention is directed to systems, devices and methods for trans-septally delivering carbon dioxide through a minimally invasive catheter to create a gaseous pocket or emphysema between the posterior wall of the left atrium and the esophagus during cardiac ablation of the left atrium. This pocket of gas expanded tissue serves to thermally insulate and separate the esophagus from the left atrium during ablation to prevent esophageal damage and the formation of an atrial-esophageal fistula. The system comprises a control system to precisely deliver the gas to a desired location through a needle-based catheter assembly.

摘要： Apparatus, consisting of a catheter having a distal end and a predefined outer diameter. The apparatus also has a plurality of elastic filaments, each filament having at least one electrode fixed thereto and having two ends fixed within the catheter distal end to hold the filament as a loop. The loop intertwines with one or more other loops of the other filaments so that the plurality of the filaments forms an open lattice, which expands when uncompressed to a lattice diameter at least 5 times greater than the outer diameter of the catheter.

摘要： A device for restraining a guide wire includes a base having a recessed formation configured to receive a portion of the guide wire, and a flexible lid configured to fit on the base. The lid has a main sheet portion covering the portion of the guide wire and a plurality of fingers separated by gaps and extending downwardly from a peripheral edge of the main sheet portion to surround the base. Sandwiched between the lid and base, the guide wire extends through gaps between the finger members. Constructed of sheet material, the lid is flexibly movable between a closed configuration wherein the fingers are flexed inwardly engaging the base, and an open configuration wherein the fingers are flexed outwardly releasing the base. Alternatively, a clamping device for restraining a guide wire includes top and bottom clamp members and a pivot connection, wherein the top clamp member has a handle end and a securing end and wherein the pivot connection enables the top clamp member to pivot between a closed position restraining the guide wire and an open position releasing the guide wire.
