Abstract:
1. A system for permitting the confined and controlled treatment of a target area [TA] of an internal body lumen using negative pressure applied to the target area [TA], the system being configured to permit target area treatment to proceed without interrupting the flow of bodily fluid through the body lumen, the system comprising: a resilient stent [ a perforated resilient liner [ a catheter tube [ whereby the system is configured so that (a) the system may be delivered into the internal body lumen, (b) the plenum may be inflated so as to seal off a target area [TA] within the body lumen with the target area [TA] defined generally by the proximal and distal portions of the stent at proximal and distal ends of the target area [TA], respectively, and by the body lumen wall and the external surface of the stent along the sides of the target area [TA], and (c) a negative pressure may be applied to the lumen of the catheter tube from a source connected to the proximal end of the catheter tube so as to create a negative pressure environment in the target area [TA] of the body lumen without impacting the inflated plenum and without impacting the ability of body lumen fluid to flow through the internal area of the stent, thereby permitting therapy to proceed without disrupting the natural flow of bodily fluids or the delivery of nutrients within the body lumen during therapy.
