Abstract: In some examples, a system includes a medical device comprising an elongate body configured to advance through layers of tissue of a patient, a lumen extending through the elongate body, a fluid line configured to supply fluid to the lumen, and a pressure sensor positioned within the lumen or the fluid line. The system may further include processing circuitry configured to receive, from the pressure sensor, a signal corresponding to the pressure of the fluid at each of a plurality of time points, determine, for each time point: a corresponding amplitude value of the signal, a difference between two amplitude values of the signal, an amplitude oscillation status of the signal, a position of the elongate body based on the difference and the amplitude oscillation status; and provide an indication of the position of the elongate body relative to the layers of tissue.

Abstract: An implantable medical device assembly includes a mounting structure, an electrode, and fixation tines. The electrode protrudes from a surface of the structure, offset proximally from a distal end of the structure, and approximately centered between first and second sides of the structure. Each tine extends away from the surface—a first adjacent the first side, and a second adjacent the second side. Each tine is elastically deformable from a relaxed condition, in which the tine extends toward a proximal end of the structure, to an extended condition, in which the tine extends away from the distal end of the structure. A delivery tool has first and second longitudinally extending sidewalls to receive passage of the structure therebetween. When the structure distal end is located between proximal ends of the sidewalls, a rail-like edge of each sidewall receives, and elastically deforms to the extended condition, a corresponding tine.

Abstract: A system and method of implanting pacing lead in a patient's heart. The system may include a catheter configured to by inserted through the coronary sinus ostium such that the distal end region of the catheter is positioned past the anterolateral vein and proximate at least one septal perforating vein. The catheter is configured to inject contrast proximate the septal perforating vein to identify an implant region for a pacing lead. Further, a controller is configured to deliver pacing therapy to the implant region.

Abstract: An implantable medical device assembly includes a mounting structure, an electrode protruding from a surface of the structure, between opposing sides thereof, and tissue-penetrating fixation tines, each extending from a corresponding shoulder of the structure surface, adjacent to the opposing sides. In a relaxed condition, each tine extends away from the surface and then bends toward a proximal end of the structure and back toward the surface. In an extended condition, each tine bends toward a distal end of the structure and extends along the corresponding shoulder. A holding member of a delivery tool has opposing sidewalls defining a cavity, wherein each sidewall includes a rail-like edge that fits in sliding engagement with a corresponding shoulder, to deform a corresponding tine into the extended condition, when an operator passes the assembly into the cavity. Applying a push force, to move the assembly back out form the cavity, releases the tines.

Abstract: An implantable medical device system includes a pacemaker and an implantable cardioverter defibrillator (ICD). The pacemaker is configured to confirm a hemodynamically unstable rhythm based on an activity metric determined from an activity sensor signal after detecting a ventricular tachyarrhythmia and withhold anti-tachycardia pacing (ATP) pulses in response to confirming the hemodynamically unstable rhythm. The pacemaker may deliver ATP when a hemodynamically unstable rhythm is not confirmed based on the activity metric. The ICD is configured to detect the ATP and withhold a shock therapy in response to detecting the ATP in some examples.
