Abstract
A guidewire includes: a shaft having a proximal end, a distal end, and a body extending from the proximal end to the distal end; a blunt tip; and a sleeve; wherein the body of the shaft comprises at least a segment that is surrounded by the sleeve, the segment coupled to the blunt tip; and wherein the segment of the body of the shaft comprises a flat portion having one or more openings extending through a thickness of the flat portion.
Claims4
A guidewire, comprising:
- a shaft having a proximal end, a distal end, and a body extending from the proximal end to the distal end;
- a blunt tip;
- and
- a sleeve,
- wherein the body of the shaft comprises at least a segment that is surrounded by the sleeve, the segment coupled to the blunt tip,
- wherein the segment of the body of the shaft comprises a flat portion having a width perpendicular to a longitudinal axis of the shaft, and a thickness that is less than the width, wherein the flat portion has one or more openings extending through the thickness of the flat portion from a first surface of the flat portion to a second surface of the flat portion opposite the first surface, and wherein one of the one or more openings is at a center of the width of the flat portion, and
- wherein the one or more openings comprise an elongated opening at the first surface, the elongated opening extending through the thickness of the flat portion, wherein the flat portion has a long side that is parallel to a longitudinal axis of the guidewire, and wherein the elongated opening has a long side that is parallel to the long side of the flat portion, and a short side that is perpendicular to the long side of the flat portion.
