First Claim
Patent Images
1. A medical device used to allow gases to exit a lung of a patient through a pneumostoma in a chest, wherein the medical device comprises;
- a vent adapted to be inserted into the chest through the pneumostoma to permit gases to exit a lung of the patient through the pneumostoma via the vent, wherein the vent includes,a distal opening in a distal end of the vent adapted to admit gases from the lung,a proximal opening in a proximal end of the vent adapted to allow gases from the lung to exit the vent outside of the chest of the patient, anda tubular body adapted to slide into the pneumostoma and sized so as to place the distal end of the vent within the lung while the proximal end of the vent is external to the chest; and
a chest mount having an adhesive surface adapted to releasably secure the chest mount to the chest of the patient, wherein the chest mount includes,an aperture through the chest mount, which aperture is stiff and less compliant than a flange of the chest mount;
said flange having the adhesive surface for releasably securing the chest mount to the chest of the patient wherein the flange is thin, elastic, flexible and compliant so that it is adapted to conform to the chest of the patient; and
whereby the distal end of the vent is adapted to be selectively positioned within the parenchymal tissue of the lung, while the proximal end of the vent communicates with the aperture.

Abstract
A pneumostoma management system for maintaining the patency of a pneumostoma while controlling the flow of material through the pneumostoma. The pneumostoma management system includes a two-part pneumostoma management device and associated insertion and removal tools. The pneumostoma management device includes a pneumostoma vent and a chest mount for positioning and securing the vent into a pneumostoma. The pneumostoma vent includes a hydrophobic filter and/or a one-way valve.

15. A medical device used to allow gases to exit a lung of a patient through a passage which passes through a chest wall into the lung through a region of pleurodesis between visceral and parietal membranes surrounding the lung, wherein the medical device comprises;
-
a chest mount which comprises, an adhesive surface adapted to releasably secure the chest mount to the chest of the patient; an aperture through the chest mount, which aperture is stiffer and less compliant than a flange of the chest mount; and said flange having the adhesive surface for releasably securing the chest mount to the chest of the patient wherein the flange is thin, elastic, flexible and compliant so that it is adapted to conform to the chest of the patient; and a vent adapted to be inserted into the chest through the passage which passes through the chest wall into the parenchymal tissue of the lung to permit gases to exit a lung of the patient, wherein the vent comprises, a distal opening in a distal end of the vent adapted to admit gases from the parenchymal tissue of the lung, and a proximal opening in a proximal end of the vent adapted to allow gases from the parenchymal tissue of the lung to exit the vent outside of the chest of the patient and; whereby the distal end of the vent is adapted to be selectively positioned within the parenchymal tissue of the lung while the proximal end of the vent is releasably secured to the chest mount. - View Dependent Claims (16, 17, 18, 19, 20)
