Benefits of technology
"The present invention provides thin membranes made of a resorbable material that can be used to promote healing of tissues affected by open heart surgery. These membranes can be used to form patches over ruptured tissue or inserted between tissues to prevent scar or adhesion. The membranes are easy to use, can be preshaped, and are stored in sterile packaging. The technical effects of this invention include promoting proper healing of tissues and preventing complications after open heart surgery."
Problems solved by technology
The formation of excessive amounts of fibrotic or scar tissue (fibrosis) is a central issue in medicine.
Scar tissue can block arteries, immobilize joints, damage internal organs, and can in some instances generally impede a body's ability to maintain vital functions.
Every year, about 1.3 million people are hospitalized due to the damaging effects of fibrosis, yet doctors have few optimal remedies to help them control this dangerous condition.
Too much scar tissue may cause physiological roadblocks that disfigure, cripple or even kill.
As a consequence, cardiac reoperations can introduce increased risks of morbidity and mortality.

Abstract
Resorbable polylactide polymer healing membranes and methods of their applications are disclosed. In a broad embodiment, the invention features methods for inducing proper tissue healing after an open heart surgery. In one embodiment, the methods includes a step of forming a patch with a healing membrane over the open pericardium to induce proper tissue healing and placement in other open heart surgery procedures to facilitate re-entry by the surgeon.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation of U.S. application Ser. No. 10 / 660,461, filed Sep. 10, 2003 (now U.S. Pat. No. 7,704,520), which claims the benefit of U.S. Provisional Application No. 60 / 429,166, filed Nov. 25, 2002, and U.S. Provisional Application No. 60 / 409,459, filed Sep. 10, 2002, the contents of which in their entireties are hereby incorporated by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates generally to medical devices and, more particularly, to methods of applying the medical device for inducing proper healing of tissues, for example the parietal pericardium tissue, after a cardiac surgery.[0004]2. Description of Related Art[0005]The formation of excessive amounts of fibrotic or scar tissue (fibrosis) is a central issue in medicine. Scar tissue can block arteries, immobilize joints, damage internal organs, and can in some instances generally impede a body's ability to ...
