Abstract: A catheter has a catheter body and a distal tip section with needles that are positioned radially to extend outside of the distal tip section to pierce and penetrate tissue layers of a vessel or tubular region. The needles are supported in a retracted position inside the distal tip section on an elongated support member. For deployment, the needles are lifted and a portion thereof pushed through openings in the distal tip section by an actuator that is longitudinally slidable on the elongated support member. The actuator has a tapered end to help lift the needle onto the actuator. In another embodiment, an inflatable balloon member with needles is movable between retracted and deployed positions.

Abstract: An ablation system observes and monitors ablation parameters, including temperature, impedance, and/or the system's own closed-loop response to these ablation parameters in delivery of power to one or more ablation electrodes, including cessation of power delivery to one or more electrodes while maintaining power delivery to one or more other electrodes. The system comprises a catheter with one or more electrodes and a detection circuitry configured to detect an ablation parameter for each electrode, a controller coupled to the catheter, the controller having a processing unit and a memory storing instructions that, when executed by the processing unit, cause the processing unit to: receive a detected ablation parameter for each electrode from the detection circuitry, control a power supplied to each violating electrode to have a reduced power when the respective detected ablation parameter violates a defined ablation parameter, detect a rate of power reduction for each violating electrode, and stop the power supplied to each violating electrode when a respective detected rate of power reduction exceeds a threshold rate of power reduction.

Abstract: Catheter apparatuses, systems, and methods for achieving renal neuromodulation by intravascular access are disclosed herein. One aspect of the present technology, for example, is directed to a treatment device having a multi-electrode array configured to be delivered to a renal blood vessel. The array is selectively transformable between a delivery or low-profile state (e.g., a generally straight shape) and a deployed state (e.g., a radially expanded, generally helical shape). The multi-electrode array is sized and shaped so that the electrodes or energy delivery elements contact an interior wall of the renal blood vessel when the array is in the deployed (e.g., helical) state. The electrodes or energy delivery elements are configured for direct and/or indirect application of thermal and/or electrical energy to heat or otherwise electrically modulate neural fibers that contribute to renal function or of vascular structures that feed or perfuse the neural fibers.

Abstract: In a catheter system and method for assembly thereof, one end of a catheter shaft is inserted into a connector for a handle, with the connector being generally tubular and having a channel extending longitudinally therethrough. At least a lengthwise segment of the channel is sized in transverse cross-section greater than an outer cross-section of the catheter shaft. The catheter shaft is inserted into the channel of the connector such that the catheter shaft is spaced from the connector within the lengthwise segment of the channel. Adhesive is directed through a port in the sidewall of the connector into the lengthwise segment of the channel to flow circumferentially about the catheter shaft within the channel. The adhesive is allowed to cure and the connector (with the catheter adhered thereto) is retained on the handle.
