Problems solved by technology

The cable, however, is not suitable for use in bi-atrial and / or bi-ventricular sensing or pacing.
The systems and apparatus listed in Table 1 below, some of which are also described above, do not address the bi-atrial and / or bi-ventricular pacing / sensing problems discussed above, e.g., the inability to operatively connect bi-atrial and / or bi-ventricular implantable leads with an external medical device.
One such problem involves the inability to operatively connect bi-atrial and / or bi-ventricular implantable leads with an external medical device.

Embodiment Construction

[0028] In the following detailed description of the embodiments, reference is made to the accompanying drawings which form a part hereof, and in which are shown by way of illustration specific embodiments in which the invention may be practiced. It is to be understood that other embodiments may be utilized and structural changes may be made without departing from the scope of the present invention.

[0029] The present invention shall first be described generally with reference to FIG. 1. Various embodiments of the present invention shall be described with reference to FIGS. 2-12.

[0030] FIG. 1 generally illustrates a cable apparatus 60 in accordance with the present invention. The patient safety cable apparatus 60 is used for connecting an external medical device 12, e.g., a programmer, to one or more implantable leads 16 (e.g., bi-atrial and / or bi-ventricular leads). As illustrated therein, implantable leads 16 are located within the patient's body and extend beyond the body externall...

Abstract

A bi-atrial and / or bi-ventricular patient safety cable includes a multi-conductor insulated external cable having a Y-connector portion, an external lead connector assembly, and two or more lead adaptors. The patient safety cable is used to electrically connect one or more implantable leads "in parallel" to an external medical device.

Description

[0001] The present invention relates to patient safety cables. More particularly, the present invention pertains to bi-atrial and / or bi-ventricular patient safety cables such as for use with implantable leads and external medical devices and methods for their use.[0002] The earliest instances of relatively prolonged cardiac stimulation, namely cardiac pacing, of a patient's heart was effected through implanted cardiac leads attached to the heart muscle at distal electrode ends and extended through an incision in the patient's skin. Initially, cardiac pacing was employed during postoperative recovery from cardiac surgery, and the attachment to the heart was made to the epicardium during the surgical procedure. To effect unipolar pacing of the heart, a single such implantable pacing lead was employed in conjunction with a subcutaneously implanted or skin surface return electrode coupled to an external lead conductor. To effect bipolar pacing of the heart, two such implantable pacing l...
