Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
128 words
A guidewire gripping device which may be attached to a medical guidewire comprising: (a) an elongated, cylindrical body comprised of an elastic material having an elongated slot which extends to the circumference thereof and is adapted to receive a guidewire, said slot being biased to grip a guidewire placed therein by the elastic nature of said cylindrical body; and (b) handle means attached to and extending from said elongated, cylindrical body on either side of said elongated slot for application of force to said device to cause said slot to open for insertion of said guidewire, the internal sides of said slot acting to frictionally grip said guidewire, said slot operable to grip said guidewire having a diameter falling within the range of 0.009 inches to 0.018 inches.
