Catheters, catheters for use in the procedure under ultrasound guidance, and associated methods

摘要

The catheter includes a catheter tube, and a echogenic structure extending from the proximal portion to the distal end of the catheter tube of the catheter tube, a portion of the echogenic structure within the distal end of said catheter tube and it is at least partially formed. Such a catheter may exhibit improved echogenicity. A method of forming a tool for a clinical procedure performed on the subject by utilizing ultrasound guidance, the step of forming the catheter, and a step of forming a portion of the echogenic structure within the distal end of said catheter I include. Method for ultrasound guidance for a clinical procedure performed on a subject, may comprise such a catheter.
