摘要
A method of forming a urinary catheter is disclosed that includes injecting a polymer melt through a primary melt channel and into an elongated recess around an outer surface of a core; and controlling a first pressure of the polymer melt in a first secondary melt channel separately and individually from a second pressure of the polymer melt in a second secondary melt channel and reducing stress of the polymer melt along the elongated recess. Opening the mould and removing the core provides a moulded intermittent urinary catheter having an open distal end and a closed proximal tip.
