Abstract

A temporary pacemaker combines technologies of the implantable pacemaker, the waterproof watch, with a separate remote-control programming unit that communicates with the pacemaker via IR radiation. An LCD readout on the temporary pacemaker continuously reports on current settings, and is monitored periodically, as well as during the setting process. The programming unit is aimed at an IR sensor on the pacemaker, and its dedicated controls are used for setting, with the aid of prompting messages on its own LCD panel. Battery life is about 6-9 months, while that for the lithium battery in the sealed and sterilizable pacemaker approaches five years.

A multi-conductor connector and an adapter for use with a temporary external pacemaker, is disclosed which reduces the complexity of connecting temporary pacing leads, adapters, extension cables, heart wires or other miscellaneous cables to a pacing device. It also reduces the possibility of inadvertent removal/disconnection of these patient connected cable systems, and yet allows for a quick release.

Claims

1. A lead connector block for connection with a medical device having a connector cavity with a plurality of alignment tabs defined in said connector cavity, comprising:

a. means for proper orientation of an exterior perimeter of said lead connector block with said connector cavity in said medical device, said means for proper orientation including a specific geometrical shape of said exterior perimeter of said lead connector block, and including at least four adjacent sides and at least one end surface, three of said sides aligned at right angles to each other and a fourth side aligned obliquely to two adjacent of said sides for removable insertion into and alignment with said device in a first horizontal orientation in the direction of said end surface;

b. opposing alignment tabs extending horizontally from said lead connector block for alignment with said alignment slots in said device;

c. indication means on said lead connector block for indicating when said lead connector block is not fully inserted or connected with said device;

d. a female lead pin connector on said end surface; and

,

e. a lead which extends from one of said sides of said lead connector block in a second orientation that is generally perpendicular to the one of said sides and is generally perpendicular to the first orientation.

2. The lead pin connector of claim 1 comprising one or more electrical circuits.

3. The lead connector block of claim 1 comprising means for resisting inadvertent removal from said medical device due to the right angle geometry of the lead extending from said lead connector block.

4. The lead connector block of claim 1 comprising means for engaging said medical device with a snapping action.

5. The medical device of claim 1 comprising a connecting pin which is a male pin.

6. The medical device of claim 1 comprising a connecting pin of one or more electrical circuits.

7. The medical device in claim 1, wherein said lead extends from said lead connector block at a right angle.

8. A lead connector for connection with a medical device having a connector cavity with a plurality of alignment tabs defined in said connector cavity, comprising:

a. means for proper orientation of an exterior perimeter of said lead connector block with said connector cavity in said medical device, said means for proper orientation including a specific geometrical shape of said exterior perimeter of said lead connector block, and including at least four adjacent sides and at least one end surface, three of said sides aligned at right angles to each other and a fourth side aligned obliquely to two adjacent of said sides for removable insertion into and alignment with said device in a first horizontal orientation in the direction of said end surface;

b. opposing alignment tabs extending horizontally from said lead connector block for alignment with said alignment slots in said temporary pacemaker device;

c. a female lead pin connector on said end surface; and

d. a lead which extends generally perpendicularly from one of said sides of the lead connector block in a second orientation that is also generally perpendicular to the first orientation.
