Device for adapting a pacemaker lead to a pacemaker
First Claim
1. An adapter for use in a coping a generally cylindrical terminal electrode assembly to a device having a jack for receiving the assembly, the terminal electrode assembly being undersized relative to the dimensions of the jack, the adapter comprising:
- a thin-walled tubular portion defining a hollow bore terminating in an end wall at a distal end thereof and an entry opening at a proximal end thereof, the outer diameter of the tubular portion being selected to match the inner diameter of the jack, the diameter of the tubular portion being selected to match the outer diameter of the terminal electrode assembly;
means for releasably latching the adapter within the jack of the device;
means for releasing the latching means and withdrawing the adapter from the jack, wherein the releasing and withdrawing means is detachable from the adapter; and
wherein the releasing and withdrawing means further comprises;
a tab extending from one side of the tubular portion outwardly past the entry opening; and
means defining a pair of notches located to establish a separation point to facilitate breaking off the tab from the tubular portion.

Abstract
A lead-to-pacemaker adapter allows the use of a smaller diameter lead connector than that for which the pacemaker was designed. The pacemaker is shipped with the adapter installed. If the adapter is not to be used, provision is made for its easy removal. The adapter is shown and described for use in a unipolar lead system. The adapter permits direct electrical connection from the terminal pin electrode to the pacemaker connector block and its terminal set screw without the interposition of any intermediate connecting elements.

16. An adapter for use in coupling a terminal electrode assembly including a plug to a device having a jack for receiving the plug for electrical connection thereto, the plug having a lead pin of a first diameter extending from a plug body having a second diameter substantially larger than the first diameter, the jack including a lead pin receptacle having a third diameter designed to receive a lead pin of a size larger than the first diameter, a main receptacle portion having a fourth diameter designed to receive a plug of a size larger than the second diameter, and an electrode for making electrical contact between the lead pin and the device, the adapter comprising:
a generally cylindrical, thin-walled tubular portion defining an end wall at a first end and an entry opening at a second end of the tubular portion, the end wall having an opening matching the first diameter for permitting the lead pin to pass therethrough for connecting to the electrode of the jack when the adapter is inserted in position within the main receptacle portion and the plug body is inserted within the tubular portion. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
