Abstract
Abstract An extendable guidewire system for introducing a dilatation catheter into the arterial system of a patient. The guidewire system has guidewire (11) and extension (12) sections with a connection (10) therebetween which permits the two sections to be joined together and separated simply by twisting the two sections to effect a threaded connection (15, 26). One of the sections can be used for positioning the catheter within the cardiovascular system, and the other section an be employed to extend the wire to change catheters.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
96 words
An extendable guidewire system comprising: a) a main guidewire section adapted to be inserted into a patient's vascular system which has a mating end adapted to extend out of the patient; b) a guidewire extension section having a mating end; c) a connection therebetween including an open-ended, internally threaded female member on a mating end of one of the guidewire sections and a threaded male member on the mating end of the other guidewire section which is adapted to be inserted into and threadably engaged with the female member to releasably secure the two sections together.
Claim 2
Dependent Claim
96 words
An extendable guidewire system comprising: a) a main guidewire section adapted to be inserted into a patient's vascular system which has a mating end adapted to extend out of the patient; b) a guidewire extension section having a mating end; c) a connection therebetween including an open-ended, internally threaded female member on a mating end of one of the guidewire sections and a threaded male member on the mating end of the other guidewire section which is adapted to be inserted into and threadably engaged with the female member to releasably secure the two sections together.
Claim 3
Dependent Claim
36 words
The extendable guidewire system of claim 1 wherein the female member is fixed to the distal end of the guidewire extension section and the male member is on the proximal end of the main guidewire section.
Claim 4
Dependent Claim
23 words
The extendable guidewire system of claim 1 wherein the female member is rotatably mounted about the distal end of the guidewire extension section.
Claim 5
Dependent Claim
