Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
82 words
A fiberoptic catheter assembly comprising: a catheter; a fiberoptic disposed in said catheter; a first connector portion coupled to said catheter and said fiberoptic; means, coupled to said first connector portion, for providing information indicative of size of at least one of said catheter and said fiberoptic; a second connector portion removably connected to said first connector portion and operatively associated with said providing means; and means, coupled to said second connector portion, for receiving the information indicated by said providing means.
Claim 2
Dependent Claim
82 words
A fiberoptic catheter assembly comprising: a catheter; a fiberoptic disposed in said catheter; a first connector portion coupled to said catheter and said fiberoptic; means, coupled to said first connector portion, for providing information indicative of size of at least one of said catheter and said fiberoptic; a second connector portion removably connected to said first connector portion and operatively associated with said providing means; and means, coupled to said second connector portion, for receiving the information indicated by said providing means.
Claim 3
Dependent Claim
72 words
The fiberoptic catheter assembly of claim 1 wherein: said first connector portion comprises a male plug; said providing means includes grooves indicative of information about the size of the fiberoptic catheter; said second connector portion comprises a female receptacle; said receiving means includes switches of controllable conductive states; and said grooves being selectively positioned relative to said switches to control the conductive state of said switches to provide information about the catheter.
