摘要： Retention devices for use with an implantable medical device (IMD) are disclosed. An illustrative retention device may comprise an elongate body including a bore configured to receive and substantially surround an implantable lead of the IMD and an outer surface configured to receive a suture. The retention device may also include a securing mechanism configured to push against tissue of the patient.

摘要： Implantation of a cardiac stimulus system using an illuminating catheter system, and devices for such implantation. Multiple catheter systems for allowing for selective visualization of the internal thoracic vasculature are discussed and disclosed. A multiple lumen catheter may be used to selectively direct a contrast agent to a desired portion of the thoracic vasculature which may include the internal thoracic vein(s) and/or one or more intercostal veins.

摘要： Implantation of a cardiac stimulus system using the intercostal veins. Superior, intercostal, and inferior access methods are discussed and disclosed. Superior access may be performed by entering the brachiocephalic vein from a jugular, subclavian, or other vein, and then accessing the internal thoracic vein, traversing a portion of the internal thoracic vein and then accessing an intercostal vein therefrom. Inferior access may be accomplished inferior to the lower rib margin via the superior epigastric vein, advancing superiorly into the internal thoracic vein and then accessing an intercostal vein therefrom. Intercostal access may include creating an opening in an intercostal space between two ribs and advancing a needle using ultrasound guidance to enter the intercostal vein directly.

摘要： Implantable medical devices (IMD) such as a cardiac pacemakers may include a sensor and electrodes. In some cases, the IMD may include electronics to use the sensor to determine the heart rate of a patient's heart. The electronics may use the electrodes to deliver pacing pulses to the heart at a first energy level if the heart rate is below a threshold and pace the heart at an enhanced energy level if the heart rate is above the threshold.

摘要： Implantation of a cardiac stimulus system using parasternal access to the ITV is provided. Superior access may be achieved using parasternal locations in the upper ribcage to access the ITV. Inferior access may be achieved using parasternal locations in the lower ribcage to access the ITV. Parasternal access may include creating an opening in an intercostal space between two ribs and advancing a needle using ultrasound guidance.

摘要： Implantation of a cardiac stimulus system into the mediastinum using the ITV. Superior, intercostal, and inferior access methods are discussed and disclosed. Superior access may be performed using the brachiocephalic vein to access the ITV, with access to the brachiocephalic vein achieved using subclavian vein, using standard visualization techniques. Inferior access may be accomplished inferior to the lower rib margin via the superior epigastric vein. Intercostal access may include creating an opening in an intercostal space between two ribs and advancing a needle using ultrasound guidance.

摘要： Implantable devices and systems include one or more leads adapted to be emplaced in the internal thoracic vein (ITV) of a patient. The lead may include features to adapt the lead for such placement. An associated device for use with the lead may include operational circuitry adapted for use with a lead having an electrode for sensing and/or therapy purposes coupled thereto. Methods for implantation and use of such devices and systems are disclosed as well.

摘要： Various aspects of the present disclosure are directed toward methods, apparatuses, and systems that include an implantable medical device comprising an implantable lead, a suture sleeve having an interior surface defining a lumen of the suture sleeve that receives the implantable lead, and an engagement feature configured to non-removeably secure the suture sleeve to the implantable lead.

摘要： An IMD may include a housing with a controller and a power supply disposed within the housing. A distal electrode may be supported by a distal electrode support that biases the distal electrode toward an extended position in which the distal electrode extends distally from the distal end of the housing and allows the distal electrode to move proximally relative to the extended position in response to an axial force applied to the distal electrode in the proximal direction. In some cases, the distal electrode support may include a tissue ingrowth inhibiting outer sleeve that extends along the length of the distal electrode support and is configured to shorten when the distal electrode moves proximally relative to the extended position and to lengthen when the distal electrode moves back distally toward the extended position in order to accommodate movement of the distal electrode.
