Crossover adapter and crossover lead
a technology of adapters and leads, applied in the field of reverse polarity pacing adapters, can solve the problems of not being clinically interested in stimulating the heart with anodal polarity, pacing with cathodal polarity still associated with a degree of morbidity and mortality, and it is extremely difficult, if not impossible, to use conventional cardiac pacers to deliver anodal polarity pacing

Benefits of technology
Enables the delivery of anodal pacing pulses, potentially improving conduction speeds and contractility by allowing the use of biphasic waveforms with an anodal pulse preceding a cathodal pulse, addressing the limitations of conventional cardiac pacing systems.
Problems solved by technology
While small amounts of anodal currents are sometimes used to reverse charge accumulation in electrodes, improving sensing, there has not been clinical interest in stimulating the heart with anodal polarity.
This lack of interest may be because cathodal polarity pacing may be deemed to be sufficiently effective in treating heart ailments.
However, pacing with cathodal polarity is still associated with a degree of morbidity and mortality because of hitherto unrecognized slowing of conduction and reduction of contractility.
This makes it extremely difficult, if not impossible, to use conventional cardiac pacers to deliver anodal polarity pacing.

Embodiment Construction
[0023]Referring now to the drawings, wherein like reference numerals designate identical or corresponding parts throughout the several views, FIG. 1 is a diagram of a cardiac pacer and lead according to exemplary aspects of the present disclosure. In FIG. 1, the cardiac pacer 5 may generate only cathodal polarity waveforms, or may generate a biphasic waveform in which the first part of the waveform is cathodal and the second part is anodal in order to remove charge from the electrode 20 to improve sensing. The cardiac pacer 5 may be implantable and therefore battery powered, or may be external to the patient and be either battery powered or powered from an external source, such as the main power grid. As can be appreciated, the cardiac pacer 5 may generate pacing pulses to address a wide variety of cardiac passing issues.
[0024]Connected to the cardiac pacer 5 is a lead that includes a lead connector 10, a lead cable 15, and an electrode 20. Thought the lead is shown as having only o...

Abstract
An adapter includes a first connector, a second connector, and a circuit that reverses a polarity of a signal received at the first connector. Moreover, a lead includes a connector including a cathode terminal and an anode terminal, an electrode including a tip and a ring, and a circuit that connects the anode terminal of the connector to the tip of the electrode and that connects the cathode terminal of the connector to the ring of the electrode.

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a divisional of U.S. application Ser. No. 16 / 038,660, filed Jul. 18, 2018, and is based upon and claims priority to U.S. Provisional Application No. 62 / 560,857 filed Sep. 20, 2017, the entire contents of each of which are incorporated herein by reference.BACKGROUNDField of the Invention[0002]The present disclosure is directed to leads for cardiac pacing, and specifically to an adapter and leads for pacing with reverse polarity.Description of the Related Art[0003]Conventional cardiac pacing uses cathodal polarity to stimulate the heart. While small amounts of anodal currents are sometimes used to reverse charge accumulation in electrodes, improving sensing, there has not been clinical interest in stimulating the heart with anodal polarity. This lack of interest may be because cathodal polarity pacing may be deemed to be sufficiently effective in treating heart ailments. However, pacing with cathodal polarity is still as...
