Abstract
Polymer catheters and guidewires for use in intravascular surgery, and more particularly polymer catheters and guidewires micro-machined with a micro-cutting machine to provide sufficient flexibility to travel through a patient's vasculature while retaining sufficient torquability to transmit torque from a proximal end to the distal end of the catheter or guidewire, and methods of producing the same.
Claims23
A catheter device, comprising:
- an elongated member including a proximal portion, a distal portion, and a lumen extending therethrough, the elongated member being formed of a stock material, wherein the distal portion includes
- an outer surface,
- an inner surface, and
- a plurality of fenestrations formed in the stock material and being arranged in a repeating pattern, the fenestrations having a depth extending between the outer surface and the inner surface, wherein the repeating pattern of fenestrations extends across a length of at least the distal portion of the elongated member;
- and
- an elastomeric filling material encapsulating the distal portion and filling the full depth of the fenestrations between the outer surface and the inner surface of the elongated member.

A catheter device, comprising:
- an elongated member having a proximal portion and a distal portion, wherein the elongated member is formed of nitinol and wherein a lumen of the elongated member has a continuous diameter, the elongated member including
- an outer surface,
- an inner surface, and
- a plurality of fenestrations formed in the nitinol and being arranged in a repeating pattern, the fenestrations having a depth extending between the outer surface and the inner surface, wherein the repeating pattern of fenestrations extends across a length of at least the distal portion of the elongated member;
- and
- an elastomeric filling material encapsulating the distal portion and filling the full depth of the fenestrations between the outer surface and the inner surface of the elongated member.

A catheter device, comprising:
- an elongated member including a proximal portion, a distal portion, and a lumen extending therethrough, the elongated member including
- an outer surface,
- an inner surface, and
- a skeletal structure formed within the elongated member, the skeletal structure comprising a repeating pattern of fenestrations extending across a length of at least a portion of the distal portion of the elongated member, the fenestrations having a depth extending between the outer surface and the inner surface;
- and
- an elastomeric filling material encapsulating the distal portion and filling the full depth of the fenestrations between the outer surface and the inner surface of the elongated member.
