Abstract

Intravascular devices, systems, and methods are disclosed. In some embodiments, side-loading electrical connectors for use with intravascular devices are provided. The side-loading electrical connector has at least one electrical contact configured to interface with an electrical connector of the intravascular device. A first connection piece of the side-loading electrical connector is movable relative to a second connection piece between an open position and a closed position, wherein in the open position an elongated opening is formed between the first and second connection pieces to facilitate insertion of the electrical connector between the first and second connection pieces in a direction transverse to a longitudinal axis of the intravascular device and wherein in the closed position the at least one electrical contact is electrically coupled to the at least one electrical connector received between the first and second connection pieces.

Claims

1. An intravascular system, comprising:

an intravascular device comprising;

a flexible elongate member having a proximal portion and a distal portion,

at least one electronic component secured to the distal portion of the flexible elongate member, and

at least one electrical connector secured to the proximal portion of the flexible elongate member, wherein the at least one electrical connector is electrically coupled to the at least one electronic component secured to the distal portion of the flexible elongate member; and

a connector having at least one electrical contact configured to interface with the at least one electrical connector of the intravascular device, the connector including a first connection piece and a second connection piece, wherein the first connection piece is movable relative to the second connection piece between an open position and a closed position, wherein in the open position an elongated opening is formed between the first and second connection pieces to facilitate insertion of the at least one electrical connector between the first and second connection pieces in a direction transverse to a longitudinal axis of the intravascular device and wherein in the closed position the at least one electrical contact is electrically coupled to the at least one electrical connector received between the first and second connection pieces.

2. The system of claim 1, wherein the first connection piece is movable relative to the second piece about a pivot axis.

3. The system of claim 2, wherein a bias element urges the first and second connection pieces towards the closed position.

4. The system of claim 3, wherein the bias element is a spring.

5. The system of claim 2, wherein the second connection piece includes a recess sized and shaped to receive a portion of the intravascular device that includes the at least one electrical connector.

6. The system of claim 5, wherein the at least one electrical contact is secured to the first connection piece.

7. The system of claim 1, wherein the first piece includes at least one visual indicator for aligning the at least one electrical contact of the connector with the at least one electrical connector of the intravascular device.

8. The system of claim 7, wherein the at least one visual indicator comprises an arrow.

9. The system of claim 7, wherein the at least one visual indicator is a light.

10. The system of claim 9, wherein the light is configured to illuminate when a proper electrical coupling is achieved between the at least one electrical contact and the at least one electrical connector.

11. The system of claim 9, wherein the light is configured to illuminate a first color when a proper electrical coupling is achieved between the at least one electrical contact and the at least one electrical connector and configured to illuminate a second color when the proper electrical coupling between the at least one electrical contact and the at least one electrical connector is not achieved.

12. The system of claim 1, wherein the at least one electronic component is a pressure sensing component.

13. The system of claim 1, wherein the at least one electronic component is an intravascular imaging component.

14. The system of claim 13, wherein the intravascular imaging component includes at least one ultrasound transducer.

15. The system of claim 13, wherein the intravascular imaging component includes at least one optical coherence tomography (OCT) imaging element.

16. The system of claim 1, wherein the first connection piece is translatable relative to the second connection piece.

17. The system of claim 16, wherein the second connection piece includes at least one opening and the first connection piece includes at least one projection for movably engaging the at least one opening of the second connection piece such that the at least one opening guides translation of the first connection piece relative to the second connection piece.

18. The system of claim 17, wherein the at least one opening includes a first end and an opposing second end, and wherein the at least one projection is positioned adjacent the first end in the open position and is positioned adjacent the second end in the closed position.

19. The system of claim 16, wherein the second connection piece includes a recess sized and shaped to receive a portion of the intravascular device that includes the at least one electrical connector.

20. The system of claim 19, wherein the at least one electrical contact is secured to the first connection piece such that the at least one electrical contact is spaced from the recess of the second connection piece in the open position and extends across the recess of the second connection piece in the closed position.
