Patent ID: 8574170

Claim:
A guidewire comprising: an elongate guide member defining a longitudinal axis and having trailing and leading end segments, the leading end segment dimensioned for positioning within a body vessel, the leading end segment including a remote segment having a reduced cross-sectional dimension relative to a cross-sectional dimension of the trailing end segment, the remote segment including a pair of lateral sides extending along the longitudinal axis; and at least two fingers disposed on the remote segment, adjacent fingers being axially spaced relative to the longitudinal axis to define a predetermined distance therebetween, a first transverse dimension of each of the at least two fingers being greater than a corresponding first transverse dimension of the remote segment in contact therewith such that each of the at least two fingers project laterally beyond both of the lateral sides of the remote segment, the at least two fingers each defining a longitudinal dimension along the longitudinal axis less than the predetermined distance between the at least two fingers.
