Abstract

An example medical device system includes a reusable connector cable having a female adaptor and a first fiber optic cable disposed within the reusable connector cable. A single use device is capable of connecting to the reusable connector cable and includes a male adaptor capable of mating with the female adaptor. A second fiber optic cable extends through the single use device such that the second fiber optic cable optically connects to the first fiber optic cable when the male adaptor of the single use device is disposed within the female adaptor of the reusable connector cable. A cleaning assembly is disposed within the single use device and is capable of cleaning an end of the first fiber optic cable when the male adaptor of the single use device is mated with the female adaptor of the reusable connector cable.

First claim

What is claimed is:

1. A medical device system comprising:
a reusable connector cable including a female adaptor;
a first fiber optic cable disposed within the reusable connector cable;
a single use device capable of connecting to the reusable connector cable, the single use device including a male adaptor capable of mating with the female adaptor of the reusable connector cable;
a second fiber optic cable extending through the single use device such that the second fiber optic cable optically connects to the first fiber optic cable when the male adaptor of the single use device is disposed within the female adaptor of the reusable connector cable; and
a cleaning assembly disposed within the single use device, capable of cleaning an end of the first fiber optic cable when the male adaptor of the single use device is mated with the female adaptor of the reusable connector cable.

2. The medical device system of claim 1 , wherein the single use device comprises a single use connector cable including the male adaptor at a first end and capable of connecting at a second end to a pressure sensing guidewire.

3. The medical device system of claim 1 , wherein the single use device comprises a pressure sensing guidewire including the male adaptor at a first end thereof.

4. The medical device system of claim 1 , wherein the reusable connector cable is operably connected to a signal processing module.

5. The medical device system of claim 1 , wherein the cleaning assembly is secured to the male adaptor of the single use device.

6. The medical device system of claim 5 , wherein the cleaning assembly comprises a wiping surface that is capable of wiping the end of the first fiber optic cable.

7. The medical device system of claim 6 , wherein the cleaning assembly is biased to hold the wiping surface against the end of the first fiber optic cable.

8. The medical device system of claim 1 , wherein the second fiber optic cable is recessed within the male adaptor of the single use device.

9. The medical device system of claim 1 , wherein the male adaptor includes a pocket to accommodate the cleaning assembly when the cleaning assembly is moved into a collapsed configuration when the male adaptor of the single use device mates with the female adaptor of the reusable connector cable.

10. The medical device system of claim 9 , wherein the female adaptor of the reusable connector cable includes a vent that is positioned to correspond to the pocket when the male adaptor of the single use device mates with the female adaptor of the reusable connector cable.

11. A medical device system comprising:
a signal processing module;
a reusable connector cable operably connectable to the signal processing module, the connector cable including a female adaptor;
a first fiber optic cable disposed within the reusable connector cable;
a single use connector cable including a male adaptor capable of mating with the female adaptor of the reusable connector cable;
a second fiber optic cable extending through the single use connector cable such that the second fiber optic cable optically connects to the first fiber optic cable when the male adaptor of the single use connector cable is mated with the female adaptor of the reusable connector cable; and
a cleaning assembly disposed within the single use device, capable of cleaning an end of the first fiber optic cable when the male adaptor of the single use connector is mated with the female adaptor of the reusable connector cable.

12. The medical device system of claim 11 , wherein the single use connector cable includes the male adaptor at a first end and is capable of connecting at a second end to a pressure sensing guidewire.

13. The medical device system of claim 11 , wherein the cleaning assembly is secured to the male adaptor of the single use device.

14. The medical device system of claim 13 , wherein the cleaning assembly comprises a wiping surface that is capable of wiping the end of the first fiber optic cable and the cleaning assembly is biased to hold the wiping surface against the end of the first fiber optic cable.

15. The medical device system of claim 11 , wherein the male adaptor of the single use connector cable protects an end of the second fiber optic cable.

16. The medical device system of claim 11 , wherein the male adaptor includes a pocket to accommodate the cleaning assembly when the cleaning assembly is moved into a collapsed configuration when the male adaptor of the single use device mates with the female adaptor of the reusable connector cable.

17. The medical device system of claim 16 , wherein the female adaptor of the reusable connector cable includes a vent that is positioned to correspond to the pocket when the male adaptor of the single use device mates with the female adaptor of the reusable connector cable.

18. A method of connecting a pressure sensing guidewire to a signal processing module, the method comprising:
providing a connector cable operably connectable to the signal processing module, the connector cable including a female adaptor and a first fiber optic cable extending within the female adaptor;
providing a disposable cable including a male adaptor and a second fiber optic cable extending within the male adaptor;
providing a cleaning assembly disposed within the male adaptor;
advancing the male adaptor of the disposable cable into the female adaptor of the connector cable such that an end of the second fiber optic cable contacts the cleaning assembly; and
further advancing the male adaptor of the disposable cable within the female adaptor of the connector cable such that the cleaning assembly cleans the end of the second fiber optic cable and is bent out of the way so that the first fiber optic cable can optically connect with the second fiber optic cable.

19. The method of claim 18 , further comprising connecting a pressure sensing guidewire to the disposable cable.

20. The method of claim 19 , further comprising obtaining a pressure measurement using the pressure sensing guidewire.
