Abstract
This disclosure relates to apparatuses and methods for preventing the onset and progression of POI. In one example, a fan-like polyurethane heat-sealed bilayer that surrounds a plurality of wedge-shaped foam strips that join at a collecting foam portion, is subjected to negative pressure provided through silicone tubing which is sealed to the perforated collecting foam portion. Such negative pressure applied for approximately 48 to 72 hours after closure of the abdomen, helps prevent POI which in turn enhances patient recovery, and reduces the length of their hospital stay.
Claims19
A method for preventing the onset and progression of Postoperative Ileus (POI), comprising:
- placing a device, comprising a plurality of foam strips enveloped in a bilayer and a connecting tube in fluid communication with the bilayer, so as to envelop the bowels;
- applying negative vacuum pressure therapy to the plurality of strips, thereby drawing out fluid from the bowel tissue and preventing the onset or progression of POI;
- collapsing the plurality of foam strips enveloped in the bilayer;
- and removing the plurality of foam strips enveloped in the bilayer by retraction from an internal patient cavity of the entire device in one piece through a surgical incision of diameter of less than 2 cm in a patient.
A method for treating a tissue region within a subject, comprising:
- positioning a device comprising one or more layers encompassing one or more pliable members in a deployed configuration upon the tissue region to be treated in an internal cavity of the subject;
- tensioning a connecting tube extending from and in fluid communication with the one or more layers at a radial end of the one or more layers such that the one or more layers collapse into a retracted configuration relative to the connecting tube;
- and
- withdrawing the one or more layers in the retracted configuration from the tissue region such that the entirety of the device including the connecting tube is withdrawn from the tissue region in one piece;
- wherein the connecting tube was placed in fluid communication with the one or more layers in a pre-manufactured configuration prior to positioning upon the tissue region.
A method for preventing an onset or progression of Postoperative Ileus (POI within a subject, comprising:
- positioning a device comprising one or more layers encompassing one or more pliable members in a deployed configuration upon the tissue region to be treated within the subject;
- actuating a negative pressure within the one or more pliable members such that a fluid from the tissue region is drawn into the one or more pliable members, thereby preventing the onset or progression of POI;
- tensioning a connecting tube extending from and in fluid communication with the one or more layers at a radial end of the one or more layers such that the one or more layers collapse into a retracted configuration relative to the connecting tube;
- and
- withdrawing the one or more layers in the retracted configuration from the tissue region through a surgical incision of diameter of less than 2 cm in the subject, such that the entirety of the device including the connecting tube is withdrawn from the tissue region in one piece;
- wherein the connecting tube was placed in fluid communication with the one or more layers in a pre-manufactured configuration prior to positioning upon the tissue region.
