Balloon-free, self-retainable and threadable urethral catheter

Abstract

The present disclosure provides a balloon-free, self-retainable and threadable urethral catheter that contains special external markings to guide insertion, and that could be indwelled easily and safely. Through various experiments and the structural configuration, the balloon-free, self-retainable and threadable urethral catheter of the present disclosure can make insertion of a mushroom-tip urethral catheter easily performed by primary care medical professionals, instead of previously only been done by senior urologists with a semi-rigid stainless-steel stylet. This disclosure leads to better urine drainage and reduces irritation to the posterior wall of the bladder. With the special design of this disclosure, minor urethral structure can be overcome to insert this catheter safely.

Dependencies are inferred from the claim text.
