Abstract: This disclosure provides tools and implant techniques utilizing such tools to gain access to and implant a medical device, such as a medical electrical lead, within extravascular spaces. In one example, this disclosure provides a tool for creating a sub-sternal tunnel in a patient. The tool comprises a relatively straight guide member extending from a first end thereof to a second end thereof, a tunneling member extending from a first end thereof to a tip thereof, the tunneling member extending alongside and coplanar with the guide member, the first end of the tunneling member and the first end of the guide member being joined together, and a handle coupled to the guide member.

Abstract: A method includes locating the triangle of Koch region in the right atrium of a patient's heart; securing at least one electrode of an implantable lead or device to cardiac tissue from the triangle of Koch region to deliver ventricle-from-atrium (VfA) cardiac therapy; and testing the location or depth of the at least one electrode to configure VfA cardiac therapy. Locating the target implant region in the triangle of Koch region may include detecting an atrial slow pathway potential (ASP) or atrial pacing output.

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: An operator advances a delivery catheter through a guiding catheter, after positioning an inflatable sleeve of the guiding catheter in proximity to a target implant site on an epicardial surface. By inflating the positioned sleeve, the operator displaces the epicardial surface to create a gap that accommodates a reach of the delivery catheter. With the delivery catheter extending distally from the guiding catheter, the operator can activate the reach of the delivery catheter within the gap, and then advance the lead out through a distal-most opening of the delivery catheter. The reach may orient a fixation member of the advanced lead relative to the epicardial surface so the operator can secure the lead to the surface. The sleeve of the guiding catheter is preferably non-compliant and has a maximum diameter of at least twice the reach of the delivery catheter, when inflated.

Abstract: A medical device and medical method. The medical device includes a flexible elongate body defining a proximal end and a distal end. The elongate body defines a first lumen spanning from the proximal end to a location proximal to the distal end. A shaping member insertable within the first lumen is included, the shaping member is configured to retain a manipulated shape when the flexible elongate body is manipulated from a first configuration to a second configuration. A tip is coupled to the distal end.

Abstract: Devices, systems, and methods deliver implantable medical devices for ventricular-from-atrial (VfA) cardiac therapy. A VfA device may be implanted in the right atrium (RA) with an electrode extending from the right atrium into the left ventricular myocardium. A flexible leed, or another probe, may be advanced to the potential implantation site and used to identify a precise location for implantation of a medical device, such as an electrode, leadlet, lead, or intracardiac device. Some methods may include locating a potential implantation site in the triangle of Koch region in the right atrium of a patient's heart; attaching a fixation sheath to the right-atrial endocardium in the potential implantation site; and implanting the medical device over a guide wire at the potential implantation site. An implantable medical device may include an intracardiac housing and a leadlet, which may be delivered by these methods.

Abstract: A medical fixation device which may include an elongate body with a proximal portion, a distal portion, and define a longitudinal axis extending therethrough. A first fixation member on the proximal portion of the elongate body and a second fixation member on the distal portion of the elongate body may also be included with the medical fixation device. The first fixation member and the second fixation member may each have a delivery configuration in which the first fixation member and the second fixation member are collapsed along the longitudinal axis, and an anchoring configuration in which the first fixation member and the second fixation member each extend radially outward from the elongate body, define a septal aperture therebetween, and each have a tip facing away from each other.

Abstract: The medical device may comprise an elongate body having a proximal portion, a distal portion, and defining a lumen therethrough. Also, the medical device may include an expandable element coupled to the distal portion of the elongate body and in fluid communication with the lumen. The expandable element may define a first end and a second end, the second end being proximal to the first end. The medical device may further include a cannula surrounding at least a portion of the elongate body and the cannula may define a proximal end and a distal end. The distal end of the cannula may be disposed proximal and adjacent to the second end of the expandable element. An outer dimctcr diameter of the cannula may be substantially equal to or lesser than an outer diameter of the expandable element when inflated. The medical device may be maneuvered through a patient's body.

Abstract: Systems, devices, and methods may be used to deliver and provide cardiac pacing therapy to a patient. Leads or leadlets carrying one or more left ventricular electrodes may be positioned in or near the interventricular septum to sense and pace left ventricular signals of the patient's heart. In one example, a leadlet including one or more left ventricular electrodes may extend in the coronary sinus from a leadless implantable medical device located in the right atrium.
