Abstract: Cardiac therapy devices in the form of pacemakers and/or defibrillators including one or more leads with electrodes implanted in a vein in a posterior position in combination with one or more leads with electrodes implanted in an anterior position. The posterior position may be chosen from one or more of the azygos, hemiazygos, accessory hemiazygos, or posterior intercostal veins. The anterior position may be chosen from the internal thoracic vein, an anterior intercostal vein, or an anterior subcutaneous location. In other examples, sensors are placed for use by a cardiac monitoring or therapy system in one or more of the internal thoracic vein, the azygos vein, the hemiazygos vein, the accessory hemiazygos vein, and/or an anterior or posterior intercostal vein.

Abstract: Medical devices and methods for making and using medical devices are disclosed. An example medical device may include an implantable medical device. The implantable medical device may include an implantable pacing member having a housing and a lead input. A lead may be coupled to the lead input. The lead may be designed to extend along a pericardial space, epicardium, or both and engage a heart chamber. A passageway may be defined along a portion of the length of the lead.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
