9 Claims, 1 Drawing Figure PATENTEUAPR 16 1974 BODY IMPLANTABLE LEAD BACKGROUND OF THE INVENTION smyocardial or endocardialfor delivering the stimulating pulses from the pulse generator to the patients heart. Myocardial leads have electrodes which are secured directly into cardiac tissue. Endocardial leads are passed intravenously to the heart and the electrodes are positioned so that the tip electrode is lodged in the apex of the right ventricle of the heart.

One problem which has existed with endocardial leads is the relationship of the electrical conductors and the electrodes. In prior art endocardial leads, the tip and proximal electrodes have been metal rings which are located on the outside of the inert material covering the conductors and bonded to the rings by soldering, welding, adhesive bonding or other bonding techniques. The difficulty with this is that with the contraction of the heart the bond between the conductors and electrodes is subjected to continual stress and thus apt to break. Also the covering material is apt to be broken by the edges of the rings thereby permitting body fluids to find their way inside the lead.

The present invention overcomes the disadvantages of the prior art by eliminating the use of metal rings for the tip and proximal electrodes. Also, the need for a bond between the conductor and the electrode is eliminated. The problem of leakage of body fluids into the lead over time is also substantially eliminated. The overall construction of the lead of the present invention is much more durable and reliable than those of the prior art.

SUMMARY OF THE INVENTION Theabove advantages, features and objects of the present invention, as well as others, are accomplished by providing in a body-implantable, bipolar, endocardial lead comprising a pair of electrical conductors, means adapted to connect the proximal ends of the conductors to a source of electrical energy, means for permitting the lead to be insertedin and guided through a body vessel to a desired location inside the body, means for substantially covering the conductors with a material substantially inert to body fluids and tissue. and tip and proximal electrodes spaced from one another and connected to the distal ends of the corresponding conductors, the improvement being the formation ofthe tip and proximal electrodes as an integral part of the corresponding conductor by at least a portion of the conductor projecting through the outer surface of the covering means and being at least partially exposed to thereby form the tip and proximal electrodes respectively. In the preferred embodiment the exposed portion of each conductor is wrapped at least one turn around the covering means.

Other advantages. features and objects of the present invention will hereinafter become more fully apparent from the following description of the drawing, which illustrates a preferred embodiment of the present invention.

BRIEF DESCRIPTION OF THE DRAWING The FIGURE shows a lead in accordance with the present invention.

DESCRIPTION OF THE PREFERRED EMBODIMENT The FIGURE shows a body-implantable, bipolar, endocardial lead 10. Lead 10 comprises a pair of electri- O cal conductors l2 and 14 embedded in a covering 16.

Conductors 12 and 14 may, for example, be of the configuration and construction of the lead described in U.S. Pat. No. 3,572,344. However, it should be understood that any conductor configuration and construction compatible with body fluids and tissue may be used in the present invention. Covering 16 is made of a material which is substantially inert to body fluids and tissue, such as, for example, silicone rubber. Covering 16 is split into two legs 18 and 20 near the proximal end of lead 10. Conductors l2 and 14 are connected to metal connectors 22 and 24 respectively which connectors are adapted to be connected to a source of electrical energy such as a pulse. generator of a cardiac pacemaker. Conductors 12 and 14 and connectors 22 and 24 are made of materials which are substantially inert to body fluids and tissue and may, for example, be platinum or a platinum iridium alloy.

Also embedded in the covering 16 and extending from the juncture oflegs l8 and 20 to close to the distal end of lead 10 is a'closely wound helical coil spring 26 which is open at its proximal end 28 and crimped at its distal end 30. Spring 26 defines a lumen into which a stylet (not shown) may be inserted. Insertion of a stylet makes lead 10 sufficiently rigid so that it may be inserted in and guided through a body vessel to a desired location inside the body. Once lead 10 is in its desired location inside the body, the stylet may be withdrawn.

covering 16. The turns of electrode 34 are partially embedded in covering 16 so as to help maintain the turns in fixed position and prevent them from moving. Electrode 36 is the proximal electrode and is formed as an integral part of conductor 14. Proximal electrode 36 is formed by conductor 14 projecting through the outer surface of covering 16 at point 40 and being closely wrapped in a helical configuration toward electrode 34 for several'turns about covering 16. The turns of electrode 36 are terminated with the distal end of conductor 14 being embedded in covering 16. The turns of electrode 36 are partially embedded in covering 16 so as to help maintain the turns in fixed position and prevent them from moving.

When lead 10 is used as an enclocardial lead for a pacemaker system, lead 10 is inserted transvenously and electrode 34 is wedged in the apex of the right ventricle. Although lead 10 has been described for use in conjunction with a cardiac pacemaker system, it should be understood that lead 10 may be used in other intravascular applications, such as, for example, as a lead for a cardioversion or defibrillation system.

Although lead has been shown and described as a bipolar lead, it could also have only one electrode for use with a monopolar system. Also, although the tip and proximal electrodes 34 and 36 have been shown in a wrapped configuration around covering material 16, they could assume other configurations. An example of another configuration would be to have the electrodes just sections of conductors 12 and 14 partially embedded in and partially exposed along a section of covering material 16.

It should be understood, of course, that the foregoing disclosure relates to only a preferred embodiment of the invention and that numerous modifications or alterations may be made therein without departing from the spirit and scope of the invention as set forth in the appended claims.
