    Abstract: A transseptal catheter delivery system includes an elongate first tubular member and an elongate second tubular member receivable within the first tubular member. The first tubular member includes an adjustable portion adjacent a distal end. The second tubular member is adapted to receive an instrument to be placed in the left ventricle, and includes a curved portion adjacent its distal end in a relaxed state. The adjustable portion is deflectable toward the atrial septum to guide a puncturing tool and/or guide insertion of the second tubular member through a septal puncture into the left atrium. Within the left atrium, the curved portion is oriented toward the left ventricle to guide insertion of a guide wire, and subsequently the second tubular member, into the left ventricle. Methods of transvenously accessing a left ventricle are also provided.

    Abstract: A method of placing an electrical lead of an implantable cardiac device inside a heart of a patient. The method includes securing a tool to an atrial appendage of the heart to hold onto the atrial appendage, piercing the atrial appendage, and creating an aperture in the atrial appendage while holding the atrial appendage with the tool. The method also includes moving a distal end of the electrical lead into the heart through the aperture in the atrial appendage and into a ventricle of the heart. Furthermore, the method includes coupling the distal end of the electrical lead to cardiac tissue in the ventricle and delivering an electrical signal to the cardiac tissue in the ventricle of the heart to maintain a predetermined heartbeat of the heart.

    Abstract: Novel tools and techniques are provided for implementing intelligent assistance (“IA”) or extended intelligence (“EI”) ecosystem to placement procedures for cardiac implantable electronic device (“CIED”). In various embodiments, a computing system might analyze received one or more first layer input data (i.e., room content-based data) and received one or more second layer input data (i.e., patient and/or tool-based data), and might generate one or more recommendations for guiding a medical professional in performing a CIED placement procedure in a heart of the patient, based at least in part on the analysis, the generated one or more recommendations comprising 3D or 4D mapped guides toward, in, and around the heart of the patient. The computing system might then generate one or more XR images, based at least in part on the generated one or more recommendations, and might present the generated one or more XR images using a UX device.

    Abstract: A deflectable shaft catheter may include a handle extending laterally from a hub of the catheter to form an acute angle therewith, wherein the handle contains a wire controller and a guide that rotates in plane with the angle. A spring biased slider of the wire controller, for the aforementioned handle, or an in-line handle sans the guide, may include first and second parts between which a proximal end of the wire extends and bends into a bore formed in the first part. Alternately, the slider includes an elastomeric core sandwiched between first and second parts thereof. The slider may further include a cavity in which a spring member biases the proximal end of the wire toward a distal end of the cavity, but only forces the wire to the cavity distal end, if a predetermined spring force of the member is greater than an opposing force along the wire.

    Abstract: An implantable medical lead having an elongated lead body extending from a proximal end to a distal end, at least one conductor extending within the lead body from the proximal end to the distal end, and a fixation member having a proximal end and a distal end, the proximal end of the electrode configured to be electrically coupled to the distal end of the lead body. The fixation member includes a first delivery port and a second delivery port for releasing a therapeutic agent from the fixation member to tissue of a patient, wherein the first delivery port is positioned along the proximal end of the fixation member to deliver the therapeutic agent to endothelial cells along an endothelial layer of tissue, and the second delivery port is positioned along the distal end of the fixation member and spaced a distance from the first delivery port to deliver the therapeutic agent to myocardial tissue within a myocardial layer of the tissue, and wherein no delivery ports are positioned within the distance that the second delivery port is spaced from the first delivery port.
