Method for using an articulable tension catheter

A catheterization method, comprising:

• perforating a body with a head of a spring tensioned articulable catheter to form an entrance location,
• travelling at least a portion of the spring tensioned articulable catheter inside the body, then
• channeling a fluid out of the body through the spring tensioned articulable catheter;
• wherein the spring tensioned articulable catheter, comprises:
• the head which includes:
• 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, wherein the helical spring tensioner has a tensioner elongation length of 1-10 mm and a tensioner diameter of from 1 to 10 mm;
• 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.
