Abstract
A reduced pressure delivery system for applying a reduced pressure to a tissue site includes a manifold delivery tube having at least two lumens and a manifold having a plurality of flow channels. The manifold is disposed within a first of the lumens of the manifold delivery tube. A balloon having an inner space and being capable of assuming collapsed and expanded positions is provided. The inner space of the balloon is fluidly connected to a second of the lumens of the manifold delivery tube.

13. The reduced pressure delivery system according to claim wherein the manifold further comprises:
-
a flexible wall surrounding a primary flow passage and adapted to be placed in proximity to the tissue site, the flexible wall including a plurality of apertures through the flexible wall and communicating with the primary flow passage; a blockage prevention member positioned within the primary flow passage; a first conduit having at least one outlet fluidly connected to the primary flow passage to deliver reduced pressure to the primary flow passage; and a second conduit having at least one outlet proximate the primary flow passage or the at least one outlet of the first conduit to purge at least one of the primary flow passage and the outlet of the first conduit with a gaseous fluid during the application of reduced pressure. - View Dependent Claims (14, 15)

20. A reduced pressure delivery system for applying reduced pressure tissue treatment to a tissue site comprising:
-
an impermeable membrane having an inner space, the impermeable membrane being capable of assuming compressed and relaxed conditions; a manifold having a plurality of flow channels, the manifold positioned within the inner space of the impermeable membrane; and wherein a pressure within the inner space of the impermeable membrane is less than the pressure outside the impermeable membrane to reduce a volume of space occupied by the manifold within the impermeable membrane. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42)
