Claim 6:
7. A body cavity catheter for channeling fluids and/or objects in a body, 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 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;
an adjustment system partially enclosed in the primary lumen wall that provides a decrease and an increase, respectively, of an inter neck ring distance between the anterior neck ring and the posterior neck ring,
wherein the decrease of the inter neck ring distance increases the bias force and provides an angular orientation increase of the catheter while the increase of the inter neck ring distance decreases the bias force and provides an angular orientation decrease of the catheter,
wherein the tensioner includes a helical spring extending between the anterior neck ring and the posterior neck ring, wherein a first end of the helical spring rests on the anterior neck ring and a second end of the helical spring rests on the posterior neck ring, and
wherein the tensioner includes an anti-buckling system to prevent the helical spring from buckling.
