摘要： A leadless pacing device may include a housing having a proximal end and a distal end, and a set of one or more electrodes supported by the housing. The housing may include a first portion and a second portion, with a guide wire port extending through the second portion. A guide wire lumen may extend through the second portion of the housing and the guide wire port may be located at a proximal end of the guide wire lumen. An exposed electrode may be located on a side of the housing that is opposite a side on which the guide wire port is located. The leadless pacing device may include a fixing member on the housing and extending radially from the housing. The leadless pacing device may further include a proximal member extending proximally from a proximal end of the housing. The proximal member may be elongated.

摘要： Delivery devices, systems, and methods for delivering implantable leadless pacing devices are disclosed. An example delivery device may an outer tubular member and an inner tubular member slidably disposed within the lumen of the outer tubular member. A distal holding section may extend distally of a distal end of the inner tubular member and define a cavity therein for receiving an implantable leadless pacing device. The device may further include a hub portion including at least a first hub portion affixed adjacent to the proximal end of the outer tubular member and a second hub portion affixed adjacent to the proximal end of the inner tubular member. A first locking mechanism configured to releasably couple the outer tubular member and the inner tubular member may be disposed within the hub portion.

摘要： An implantable medical device may include each of a conductive canister, a printed circuit board assembly (PCBA), and a header. A feedthrough and ferrule couple the interior of the canister, where the PCBA is, to one or more elements contained in the header such as an antenna and/or a port for coupling to a lead. The ferrule may be directly attached to the conductive canister and the electronic circuit board. The electronic circuit board carries an RF transmitter for telemetry purposes, and has an RF ground plane layer therein. The ferrule is capacitively coupled to the RF ground plane the PCBA, and has a size and/or shape relative to the RF ground plane that provides sufficient capacitance to offer an improved RF ground plane path to the conductive canister at a desired telemetry frequency.

摘要： Systems, methods and implantable devices configured to provide cardiac resynchronization therapy and/or bradycardia pacing therapy. A first device located in the heart of the patient is configured to receive a communication from a second device and deliver a pacing therapy in response to or in accordance with the received communication. A second device located elsewhere is configured to determine an atrial event has occurred and communicate to the first device to trigger the pacing therapy. The second device may be configured for sensing the atrial event by the use of vector selection and atrial event windowing, among other enhancements. Exception cases are discussed and handled as well.

摘要： A leadless pacing device may include a power supply providing a power supply voltage, a housing having a first end, a second end, and a side extending between the first end and the second end, and a set of electrodes supported by the housing and in communication with the power supply. The housing may be angled to follow a contour of a patient's heart when the housing is positioned within the coronary sinus of the patient's heart. In some cases, an angled portion of the housing may include a smooth-curve. In some cases, an angled portion of the housing may include a first portion of the housing and a second portion of the housing at an angle of less than one-hundred-eighty degrees with respect to the first portion of the housing. One or more of the electrodes may be exposed on a concave side of the angled housing.

摘要： Delivery devices, systems, and methods for delivering implantable leadless pacing devices are disclosed. An example delivery system may comprise a delivery device, an implantable leadless pacing device, and a tether. The tether may be made of a material which allows for a lubricious, strong, no stretch, no memory tether. The tether may releasably secure the implantable leadless pacing device to the delivery device.

摘要： Delivery devices, systems, and methods for delivering implantable leadless pacing devices are disclosed. An example delivery device may include a proximal section including a deflection mechanism for deflecting the proximal section, and a distal holding section extending distally of a distal end of the proximal section and defining a cavity therein for receiving an implantable leadless pacing device. The distal holding section may be structured to have portions that flex and bend while allowing the implantable device to be recaptured within the distal holding section.
