    Abstract: Aspects of the present disclosure are directed to a unibody intravascular catheter shaft with benefits which may include a reduced diameter, and independently tunable torquability, flexibility, and pushability characteristics. While various embodiments of the present disclosure may be directed to an entire catheter shaft, various specific embodiments of the present disclosure may be directed to a unibody shaft design, which may be implemented in a portion of a catheter shaft. For example, the unibody shaft design may be advantageously implemented in a proximal shaft portion. Moreover, various embodiments of the present disclosure utilize a modular unibody design, which may be utilized for various catheter shaft applications using an outer polymer layer with variable thickness and durometer to achieve application-specific performance characteristics (e.g., catheter shaft flex).

    Abstract: Various embodiments of the present disclosure can include a high-density electrode catheter. In some embodiments, the high-density electrode catheter can include a catheter shaft including a proximal end and a distal end, the catheter shaft defining a catheter shaft longitudinal axis. In some embodiments, the high-density electrode catheter can include a shaft magnetic position sensor disposed along a distal portion of the catheter shaft. In some embodiments, the high-density electrode catheter can include a flexible tip portion located adjacent to the distal end of the catheter shaft, wherein the flexible tip portion includes a flexible framework. In some embodiments, the high-density electrode catheter can include a plurality of electrodes disposed on the flexible framework. In some embodiments, the high-density electrode catheter can include a tip magnetic position sensor disposed on a portion of the flexible framework.

    Abstract: Aspects of the present disclosure are directed to, for example, a high-thermal-sensitivity ablation catheter tip including a thermally-insulative ablation tip insert supporting a plurality of temperature sensors positioned within longitudinally-extending sensor channels and a radially-extending sensor channel within the tip insert. The sensor channels position the temperature sensors in thermal communication with a conductive shell that encapsulates, or essentially encapsulates, the ablation tip insert and the plurality of temperature sensors. Also disclosed is a method of controlling the temperature of an ablation catheter tip while creating a desired lesion using various ablative energies and energy delivery methodologies.
