Abstract

An electrical connector is described. In one implementation, the connector includes a female portion including one or more electrical contacts and a male portion including one or more electrical contacts. The female portion and the male portion each have a self-orientating geometry that allows the male portion to be mated with the female portion in any rotational position along 360 degrees of rotation. When mated, the electrical contacts of the female portion mate with corresponding one or more electrical contacts of the male portion to form one or more electrical connections between two electronic components.

Claims

1. An apparatus, comprising:

a motor drive unit;

a catheter configured and arranged to be inserted into a lumen of a patient body;

a connector configured and arranged to connect the motor drive unit to the catheter, the connector comprising

a first connector unit comprising at least one electrical contact, a lumen, and at least one key protruding into the lumen, and

a second connector unit configured and arranged for insertion into the lumen of the first connector unit, the second connector unit comprising at least one electrical contact configured and arranged for coupling to the at least one electrical contact of the first connector unit, at least one groove in an exterior surface of the second connector unit for alignment with, and receipt of, the at least one protruding key of the first connector unit, and at least one sloping section formed in the exterior surface of the second connector unit and leading to a one of the at least one groove to facilitate alignment, and receipt, of the at least one key of the first connector unit into the at least one groove of the second connector unit,

wherein the connector is configured to be rotatable when the first and second connector units are mated and rotational movement is provided from the motor drive unit, thereby rotating the connector and the catheter.

2. The apparatus of claim 1, wherein the at least one key of the first connector unit comprises a leading edge beveled to form an acute angle, wherein the leading edge is first introduced into the at least, one groove when the first and second connector units are coupled.

3. The apparatus of claim 1, wherein the second connector unit comprises a plurality of the grooves.

4. The apparatus of claim 3, wherein regions between the grooves are beveled leading toward each groove and form an acute angle at a distal end of the second connector unit.

5. The apparatus of claim 4, wherein the electrical contacts of the first connector unit comprise a plurality of pins and the electrical contact of the second connector unit comprise a plurality of apertures to receive the pins.

6. The apparatus of claim 3, wherein the first connector unit comprises a plurality of the keys.

7. The apparatus of claim 6, wherein a number of the keys is equal to a number of the grooves.

8. The apparatus of claim 6, wherein the electrical contacts of the first connector unit comprise a plurality of pins and the electrical contact of the second connector unit comprise a plurality of apertures to receive the pins.

9. The apparatus of claim 1, wherein the electrical contacts of the first connector unit comprise a plurality of pins and the electrical contact of the second connector unit comprise a plurality of apertures to receive the pins.

10. The apparatus of claim 1, wherein the electrical contacts of the first connector unit comprise a plurality of fingers spaced around a circumference of a female portion, each finger comprising a raised portion that is offset axially with respect to other fingers, and the electrical contacts of the second connector unit comprise a plurality of axially displaced conductive rings.

11. The apparatus of claim 1, wherein the first connector unit is connected to the catheter and the second conductor unit is connected to the motor drive unit.

12. The apparatus of claim 1, wherein the catheter comprises a rotator core, a drive shaft, and an imaging core.

13. The apparatus of claim 1, wherein the electrical contacts of the first connector unit comprise a plurality of fingers spaced around a circumference of a female portion, wherein each finger comprises a raised portion.

14. The apparatus of claim 13, wherein the raised portion of each finger is offset axially with respect to the raised portion of all other fingers.

15. The apparatus of claim 1, wherein the electrical contacts of the second connector unit comprise a plurality of axially displaced conductive rings.

16. The apparatus of claim 1, wherein the motor drive unit comprises the first connector unit and the catheter comprises the second connector unit.

17. The apparatus of claim 1, wherein the motor drive unit comprises the second connector unit and the catheter comprises the first connector unit.

18. An apparatus, comprising:

a motor drive unit;

a catheter configured and arranged to be inserted into a lumen of a patient body;

a connector configured and arranged to connect the motor drive unit to the catheter, the connector comprising

a first connector unit comprising at least one electrical contact, a lumen, and at least one key, and

a second connector unit configured and arranged for insertion into the lumen of the first connector unit, the second connector unit comprising at least one electrical contact configured and arranged for coupling to the at least one electrical contact of the first connector unit, at least one groove in a first surface of the second connector unit for alignment with, and receipt of, the at least one key of the first connector unit, and at least one sloping section formed in the first surface of the second connector unit and leading to a one of the at least one groove to facilitate alignment, and receipt, of the at least one key of the first connector unit into the at least one groove of the second connector unit,

wherein the connector is configured to be rotatable when the first and second connector units are mated with the at least one key received in the at least one groove and rotational movement is provided from the motor drive unit, thereby rotating the connector and the catheter.

19. The apparatus of claim 18, wherein a region adjacent the at least one groove is beveled leading toward the at least one groove.

20. The apparatus of claim 18, wherein the first connector unit comprises a plurality of the keys and the second connector unit comprises a plurality of grooves.

21. The apparatus of claim 18, wherein the motor drive unit comprises the first connector unit and the catheter comprises the second connector unit.
