    Abstract: VfA cardiac therapy uses an implantable medical device or system. The implantable medical device includes a tissue-piercing electrode implanted in the basal and/or septal region of the left ventricular myocardium of the patient's heart from the triangle of Koch region of the right atrium through the right atrial endocardium and central fibrous body. The device may include a right atrial electrode, a right atrial motion detector, or both. The device may be implanted completely within the patient's heart or may use one or more leads to implant electrodes in the patient's heart. The device may be used to provide cardiac therapy, including single or multiple chamber pacing, atrioventricular synchronous pacing, asynchronous pacing, triggered pacing, cardiac resynchronization pacing, or tachycardia-related therapy. A separate medical device may be used to provide some functionality for cardiac therapy, such as sensing, pacing, or shock therapy.

    Abstract: An implantable medical device has a housing having a proximal end, a distal end and an outer sidewall extending from the proximal end to the distal end. A fixation sheath includes a housing sheath portion extending along the outer sidewall of the housing, and a fixation member portion extending from the housing sheath portion. The housing sheath portion is advanceable from a first position along the outer sidewall of the housing in which the fixation member portion is retracted toward the proximal end of the housing to a second position along the outer sidewall of the housing in which the fixation member portion is deployed to extend away from the housing distal end for anchoring the implantable medical device at an implant site.

    Abstract: A lead-in-lead system may include a first implantable lead having a first electrode and a second implantable lead having a second electrode guided by the first implantable lead to an implantation site. The second electrode may be implanted in a patient's heart distal to the first electrode at the same implantation site or at a second implantation site. Various methods may be used to deliver the lead-in-lead system to one or more implantation sites including at the triangle of Koch for ventricle-from-atrium (VfA) therapy, at the right ventricular septal wall for dual bundle-branch pacing, or in the coronary vasculature for left side sensing and pacing.

    Abstract: A catheter assembly includes a cap and a spring-biased tethering member coupled thereto. The cap includes first and second portions, and a transition zone extending therebetween. A girth of the first portion is sized to fit within a distal-most opening of the catheter assembly; and a girth of the second portion tapers from a first size at the transition zone, which is too large to fit within the distal-most opening, to a smaller size at a distal end of the cap. The spring-biased tethering member holds the cap in open and closed positions, when the cap first portion extends within the distal-most opening, and when the cap is separated from the distal-most opening, respectively. At the closed position, the first portion is approximately concentric with the distal-most opening, and at the open position, an entirety of the cap is laterally offset from the distal-most opening.
