摘要： Extravascular implant tools that utilize a bore-in mechanism to safely access extravascular locations and implant techniques utilizing these tools are described. The bore-in mechanism may include a handle and a helix extending from the handle. The bore-in mechanism is used, for example, in conjunction with a tunneling tool to traverse the diaphragmatic attachments to access a substernal location. The tunneling tool may be an open channel tunneling tool or a conventional tunneling tool (e.g., metal rod).

摘要： 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.

摘要： 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.

摘要： 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.

摘要： A catheter assembly includes a pull wire and a control member subassembly, wherein the pull wire is secured to a post of the subassembly that may extend through a slot of a handle, and an engagement feature of the subassembly, being supported by an elastically deformable support of the subassembly resting on a railway of the handle, confronts a mating feature of the handle to interlock therewith, responsive to the support being un-deformed. The post, engagement feature, and support may be integrally formed together in a single-piece component, wherein the engagement feature may be one or two rows of teeth formed in a surface of an upper portion of the component, and the support may be a pair of flexible cantilever beam members of a lower portion of the component. Furthermore, the mating surface and railway may be integrally formed in an inner surface of a shell of the handle.

摘要： An intracardiac ventricular pacemaker includes a pulse generator for delivering ventricular pacing pulses, an impedance sensing circuit, and a control circuit in communication with the pulse generator and the impedance sensing circuit. The pacemaker is configured to produce an intraventricular impedance signal, detect an atrial systolic event using the intraventricular impedance signal, set an atrioventricular pacing interval in response to detecting the atrial systolic event, and deliver a ventricular pacing pulse in response to the atrioventricular pacing interval expiring.
