An expandable balloon may be coupled to the catheter shaft. The balloon may be capable of shifting between a folded configuration and an expanded configuration. A plurality of elongate electrode assemblies may be disposed on the balloon. A cover layer may be deposited on the electrode assemblies. Portions of the electrode assemblies may be free of the cover layer.

Abstract: A tissue modification apparatus includes at least a first plurality of grippers aligned in a plane adapted to secure a first edge of a patch of tissue. The plurality of grippers are each secured to a first force actuator. The first plurality of grippers are each adapted to pivot relative to the first force actuator about an axis perpendicular to the plane. In some cases, a plurality of grippers are attached to a force actuator by a passive force transfer mechanism. In some cases, individual force actuators are attached by pivoted connections to individual grippers. Methods of treating tissue can secure tensioned tissue to a frame to retain the tension during a treatment (e.g., cross-linking the tissue with a chemical cross-linker).

Abstract: Catheters and methods are provided for determining a fluid flow rate of fluid located near a tip assembly of the catheter and providing an indication of the fluid flow condition and/or controlling one or more functions of the catheter based on the determined fluid rate. A method includes receiving a signal from a sensor located on a tip assembly of a catheter, the signal being indicative of a fluid flow condition of fluid located near the tip assembly. A processing device determines the fluid flow condition using the signal. Based on the determined fluid flow rate, the processor causes a device to output an indication of the determined fluid flow condition.

Abstract: A catheter system includes a catheter comprising a tip assembly, the tip assembly having a plurality of electrodes and the plurality of electrodes are configured to measure electrical signals. The system also includes a processing unit configured to: receive a first electrical signal sensed by a first electrode of the plurality of electrodes and a second electrical signal sensed by a second electrode of the plurality of electrodes. A first vector is determined based on the first electrical signal that corresponds to the first electrode. A second vector is determined based on the second electrical signal that corresponds to the second electrode. A resultant vector is determined by summing at least the first vector and the second vector, wherein the resultant vector is indicative of the orientation of the tip assembly.

Abstract: A catheter adapted to determine a contact force, the catheter including a proximal segment, a distal segment, and an elastic segment extending from the proximal segment to the distal segment. The distal segment includes a plurality of tip electrodes including at least three radial electrodes disposed about a circumference of the distal segment. The radial electrodes are configured to output electrical signals indicative of a contact vector of the contact force. The elastic segment includes a force sensing device configured to output an electrical signal indicative of a magnitude of an axial component of the contact force, wherein the contact force is determined by scaling the magnitude of the axial component of the contact force by the contact vector.

Abstract: An electrophysiology system includes a catheter having a flexible catheter body with a distal portion; and electrodes disposed on the distal portion. The system includes a signal generator configured to generate an electrical signal by driving one or more currents between a first set of the electrodes, where a second set of the electrodes is configured to obtain an impedance measurement based on the electrical signal. A mapping processor is configured to receive the impedance measurement from the second set of electrodes; determine at least one impedance metric; and determine at least one lesion characteristic based on the at least one impedance metric.

Abstract: A catheter including expandable electrode assembly having a distal cap that mechanically engages a locking feature provided on the distal ends of each of two or more flexible splines forming a portion of the expandable electrode assembly is described. The distal cap defines an atraumatic distal tip of the catheter. The catheter may be used in a cardiac mapping and/or ablation procedure.
