    Abstract: A method of delivering a pacing lead may include locating a potential implantation site adjacent to or within the triangle of Koch region of a patient's heart. The method may include advancing a pacing lead to the potential implantation site. The pacing lead has an elongate body and a fixation element coupled to a distal portion and attachable to the right-atrial endocardium adjacent to or within the triangle of Koch region. The method may include implanting the pacing lead at the potential implantation site to or sense electrical activity of the left ventricle in the basal and/or septal region of the left ventricular myocardium of the patient's heart. The pacing lead may include a lumen configured to receive a guide wire. A sheath of a delivery system used to deliver the pacing lead may include two or more curves to facilitate implanting the pacing lead at the implantation site.

    Abstract: A guide wire system configured to guide a medical device (e.g., a medical lead) to a target area within a patient. The guide wire system may be configured to penetrate and pass through a tissue wall in the patient to guide the medical device to the target area. The guide wire system includes a support section configured to expand to substantially maintain a position relative to the tissue wall. The guide wire system includes a pull wire configured to cause the support portion to expand. The expanded support section may provide counter-traction to a distal force on the tissue wall exerted by a medical device during, for example, fixation of the medical device to the target area, or other stages of an implantation. The support section is configured to re-establish an initial configuration for proximal withdrawal from the tissue wall.

    Abstract: Methods and systems for positioning a leadless pacing device (LPD) in cardiac tissue are disclosed. A delivery device is employed that comprises a proximal end, a distal end and a lumen therebetween sized to receive the LPD. The LPD has a leadlet extending therefrom that includes a means to fixate the leadlet to tissue. The delivery device comprises an introducer to introduce the LPD into the lumen of the delivery device. The LPD is loaded in the distal end of the lumen of the delivery device. The leadlet extends proximally from the LPD while the fixation means extends distally toward the LPD. A LPD mover is configured to advance the LPD out of the delivery device. A leadlet mover is configured to advance the leadlet out of the lumen delivery device and cause the leadlet to engage with cardiac tissue.

    Abstract: The present disclosure is directed to a shuttle apparatus for detachably joining a catheter to a guidewire so that the joined catheter, extending alongside the guidewire, is in sliding engagement with the guidewire without extending around the guidewire. The apparatus comprises a collar member sized for mounting in sliding engagement around a length of the guidewire, the collar member having a longitudinal axis that approximately aligns along the length, when mounted thereabout, the length being defined between a proximal-most point of the guidewire and a distal point of the guidewire, the distal point being offset proximally from a distal-most point of the guidewire. The apparatus further comprises a plug member coupled to the collar member, the plug member having a longitudinal axis, and the plug member being sized to fit within an opening of the catheter for detachable engagement therewith.

    Abstract: An active return curve deflectable catheter includes an elongate member, a fixation member, a deflection assembly, and a pull wire. The fixation member is coupled to a distal portion of the elongate member. The deflection assembly includes a hub assembly coupled to a proximal end of the elongate member, a handle, and a control member. The pull wire extends from the control member through the hub assembly to the fixation member. The elongate member is configured to deflect from an initial configuration to a deflected configuration in response to a pull force applied to the pull wire by actuation of the control member in a first direction.
