摘要： An electrophysiology catheter includes a catheter body and at least one porous electrode. The porous electrode is formed by forming a substrate of a first more noble metal and forming an alloy on the substrate. The alloy includes a second more noble metal and a less noble metal. The alloy is de-alloyed to form a porous matrix consisting essentially of the second more noble metal. The more noble metals can be gold, copper, and/or platinum, while the less noble metal can be silver, zinc, and/or lead.

摘要： 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).

摘要： The present disclosure provides electroporation systems and methods of preconditioning tissue for electroporation therapy. An electroporation generator includes an electroporation circuit, a preconditioning circuit, and a controller. The electroporation circuit is configured to be coupled to a catheter for delivering the electroporation therapy to target tissue of the patient. The electroporation circuit is further configured to transmit an electroporation signal through the catheter. The preconditioning circuit is configured to be coupled to a preconditioning electrode for stimulating skeletal muscle tissue of the patient. The preconditioning circuit is further configured to transmit a preconditioning signal to the preconditioning electrode. The controller is coupled to the electroporation circuit and the preconditioning circuit, and is configured to synchronize transmissions of the electroporation signal and the preconditioning signal such that the preconditioning signal is transmitted prior to transmission of the electroporation signal.
