Abstract
An intravascular device, such as s guidewire device, includes a hollow proximal section and a hollow distal section joined to the proximal section and extending distally from the proximal section to form a continuous lumen extending from a proximal end of the device to a distal end of the device. An inner member extends from the proximal end to the distal end and is joined to the distal end. The inner member is translatable within the lumen in response to applied tension. At least the distal section includes a micro-fabricated cutting pattern that enables deflection of the distal end in response to the application of tension to the inner member.

An intravascular device, comprising:
- an elongated hollow proximal section;
- an elongated hollow distal section joined to the proximal section and extending distally from the proximal section to form a continuous lumen extending from a proximal end of the device to a distal end of the device;
- and
- an inner member extending from the proximal end to the distal end, the inner member being joined to the distal end and being translatable within the lumen in response to applied tension or compression,
- wherein at least the distal section includes a micro-fabricated cutting pattern that enables deflection of the distal end in response to the application of tension or compression to the inner member, at least a portion of the cutting pattern comprising a spiral pattern configuration with a plurality of bridges connecting adjacent spiral coils of the spiral pattern, the spiral pattern extending to the distal end of the device, wherein the spiral coils of the spiral pattern spiral along the intravascular device at an angle offset from a transverse axis of the intravascular device, wherein at least one bridge of the plurality of bridges extends perpendicular to adjacent spiral coils connected by the at least one bridge, wherein at least two adjacent bridges of the spiral pattern extend angularly offset relative to one another in an axial direction of the intravascular device.
