    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.

    Abstract: A fixation member of an electrode assembly for an implantable medical device includes a tissue engaging portion extending along a circular path, between a piercing distal tip thereof and a fixed end of the member. The circular path extends around a longitudinal axis of the assembly. A helical structure of the assembly, which includes an electrode surface formed thereon and a piercing distal tip, also extends around the longitudinal axis and is located within a perimeter of the circular path. The tissue engaging portion of the fixation member extends from the distal tip thereof in a direction along the circular path that is the same as that in which the helical structure extends from the distal tip thereof. The electrode assembly may include a pair of the fixation members, wherein each tissue engaging portion may extend approximately one half turn along the circular path.

    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.
