Described embodiments include an apparatus that includes an expandable structure, configured for insertion into a body of a subject, and a plurality of conducting elements coupled to the expandable structure. Each of the conducting elements comprises a respective coil and has an insulated portion that is electrically insulated from tissue of the subject, and an uninsulated portion configured to exchange signals with the tissue, while in contact with the tissue. Other embodiments are also described.

An apparatus includes a catheter assembly and an end effector. The catheter assembly includes an outer sheath with a distal end. The end effector is associated with a distal end of the catheter assembly. The end effector includes a panel assembly with microelectrodes for electrophysiological (EP) mapping. The microelectrodes are configured in a matrix within the panel assembly and provide multiple points of contact with the target tissue for EP mapping. The panel assembly can transition between a first contracted state and a second expanded state. The panel assembly can fit within the outer sheath in the first state. The panel assembly can expand outwardly away from a longitudinal axis defined by the catheter assembly in the second state once exposed distally relative to the distal end of the outer sheath.

An electrode assembly for use with an electrophysiological catheter has a plurality of independently controlled ablation electrodes distributed radially around the electrode assembly. Two ablation electrodes may be positioned in opposition to each other. The electrode assembly may also have microelectrodes for sensing tissue and/or temperature. Methods for using a catheter equipped with such an electrode assembly may include preferentially emitting energy in a radial direction.

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.

A method and device that provide improved visualization of soft tissue, such as renal arteries, renal veins and lymph nodes in guiding catheter placement and positioning in the renal region or vasculature. The method and device enable visualization of an electrophysiology catheter application in the renal region which provides for improved imaging of renal structures, including renal arteries, along with one or more adjacent anatomical structures, including renal veins, lymph nodes, other adjacent organs and and/or other adjacent soft tissues that may adversely impact the formation of a lesion during a catheter ablation procedure in or around a renal artery.

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.
