Field: Medical technology (Instruments)
Classification: CPC A | IPC A

Claim 0:
1. An articulable catheter, comprising:
a head including:
a head orifice, and
a head channel connected to the head orifice;
a primary lumen wall that defines an internal primary lumen volume;
an adjustable neck that connects the head channel to the internal primary lumen volume, the adjustable neck including:
an anterior neck ring affixed to the head,
a posterior neck ring affixed to the primary lumen wall, and
a helical spring tensioner that generates a bias force between the anterior neck ring and the posterior neck ring,
a neck tube extending from the anterior neck ring to the posterior neck ring and having a plurality of circumferential bulges, wherein the helical spring tensioner is a disposed inside the neck tube; and

a secondary lumen including:
an internal portion that is enclosed along the primary lumen wall, and
an external portion that protrudes from the primary lumen wall,

a filament that runs through the internal portion and the external portion, the filament including:
an anterior filament end affixed to the anterior neck ring, and
a posterior filament end that exits from the external portion, and
an adjuster that pulls and releases the posterior filament end to provide a decrease and an increase, respectively, of an inter-neck ring distance between the anterior neck ring and the posterior neck ring,

wherein the increase of the inter-neck ring distance decreases the bias force and provides an angular orientation increase of the catheter while the decrease of the inter-neck ring distance increases the bias force and provides an angular orientation decrease of the catheter, and
wherein the posterior neck ring further includes a secondary lumen stop to block the internal portion and to let the filament freely pass through the posterior neck ring.
