Patent number: 10980570Abstract: 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.Type: GrantFiled: January 11, 2018Date of Patent: April 20, 2021Assignee: CARDIAC PACEMAKERS, INC.Inventors: G.

Patent number: 10864378Abstract: Regulating cardiac activity may include pacing the patient's heart at a starting pacing rate and instigating an intrinsic heart beat search algorithm that includes pacing at a reduced rate for a period of time and capturing electrical signals representative of cardiac electrical activity while pacing at the reduced rate in order to determine a presence or absence of intrinsic heart beats. If intrinsic heart beats are not detected, the heart may be paced at a further reduced rate for a period of time. If intrinsic beats are detected, the heart may be paced again at the starting pacing rate. This may continue until intrinsic heart beats are detected or until a lower search rate limit is reached. Diagnostic data may be collected at each stage and transmitted to a display device for analysis by a physician or the like.Type: GrantFiled: March 8, 2018Date of Patent: December 15, 2020Assignee: CARDIAC PACEMAKERS, INC.Inventors: David A.
