Abstract
A method of creating a feature on a needle. The method comprising the steps of providing a needle having a sharpened distal end for insertion into an insertion site on a subject, a proximal end, and a tubular wall defining an inner diameter and an outer diameter; gripping a distal portion of the needle about the outer diameter; gripping a proximal portion of the needle about an outer diameter; and applying a compressive force between the distal portion and the proximal portion sufficient to effect an outward buckling of the tubular wall, thereby increasing an outer diameter of the tubular wall between the distal portion and the proximal portion.
Claims8
A method of creating a feature on a needle, the method comprising:
- providing a needle having a sharpened distal end for insertion into an insertion site on a subject, a proximal end, and a tubular wall defining an inner diameter and an outer diameter;
- gripping a distal portion of the needle about the outer diameter;
- gripping a proximal portion of the needle about the outer diameter;
- and
- applying a compressive force between the distal portion and the proximal portion sufficient to effect an outward buckling of the tubular wall, thereby increasing an outer diameter of the tubular wall between the distal portion and the proximal portion.
The method of claim 2, wherein the compressive force causes at least a portion of the outer diameter of the tubular wall to buckle radially outwardly by at least 0.001 of an inch.
