Abstract
A guidewire comprising an elongate guide member dimensioned for insertion within a body vessel of a subject is disclosed. The guide member defines a longitudinal axis and has trailing and leading end segments. The leading end segment has a reduced cross-sectional dimension relative to a cross-sectional dimension of the trailing end segment. The leading end segment includes at least one finger thereon. A first transverse dimension of the finger is greater than a corresponding first transverse dimension of the leading end segment in contact therewith.
Claims29
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.
A method for manufacturing a guidewire dimensioned for insertion within a body vessel of a subject, the method comprising:
- forming a guide member defining a longitudinal axis and having trailing and leading end segments, 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 plurality of fingers, adjacent fingers being disposed in axial spaced relation at a predetermined axial distance, a first transverse dimension of each finger being greater than a corresponding first transverse dimension of the remote segment in contact therewith, each finger defining a longitudinal dimension along the longitudinal axis less than the predetermined distance between the adjacent fingers;
- and
- at least one coil mounted about at least the remote segment.
A medical guidewire comprising:
- an elongate guide member defining a longitudinal axis and having proximal and distal end segments, the distal end segment including a reduced cross-sectional dimension relative to a cross-sectional dimension of the proximal end segment, the distal segment dimensioned for positioning within a body lumen;
- and
- at least three fingers disposed along the distal end segment, adjacent fingers being spaced along the longitudinal axis to define a predetermined distance therebetween, each finger defining first and second transverse dimensions, the first transverse dimension of each finger being greater than a corresponding first transverse dimension of the distal end segment in contact therewith such that each finger extends beyond lateral edges of the distal end segment, each finger defining a longitudinal dimension along the longitudinal axis less than the predetermined distance between adjacent fingers.
