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 first 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 second adaptor capable of mating with the first 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 second adaptor is disposed within the first adaptor; and a cleaning assembly disposed within the single use device, capable of cleaning an end of the first fiber optic cable when the second adaptor is mated with the first adaptor.

2 . The medical device system of claim 1 , wherein the single use device comprises a single use connector cable including the second 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 second 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 second adaptor.

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 second adaptor.

9 . The medical device system of claim 1 , wherein the second adaptor includes a pocket to accommodate the cleaning assembly when the cleaning assembly is moved into a collapsed configuration when the second adaptor device mates with the first adaptor.

10 . The medical device system of claim 9 , wherein the first adaptor includes a vent that is positioned to correspond to the pocket when the second adaptor mates with the first adaptor.

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 reusable connector cable adaptor; a first fiber optic cable disposed within the reusable connector cable; a single use connector cable including a single use connector cable adaptor capable of mating with the reusable connector cable adaptor; 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 single use connector cable adaptor is mated with the reusable connector cable adaptor; and a cleaning assembly disposed within the single use device, capable of cleaning an end of the first fiber optic cable when the single use connector cable adaptor is mated with the reusable connector cable adaptor.

12 . The medical device system of claim 11 , wherein the single use connector cable includes the single use connector cable 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 single use connector cable adaptor.

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 single use connector cable adaptor protects an end of the second fiber optic cable.

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

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

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 first adaptor and a first fiber optic cable extending within the first adaptor; providing a disposable cable including a second adaptor and a second fiber optic cable extending within the second adaptor; providing a cleaning assembly disposed within the second adaptor; advancing the second adaptor into the first adaptor such that an end of the second fiber optic cable contacts the cleaning assembly; and further advancing the second adaptor within the first adaptor 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.
