Abstract
A method of controlling scar formation in humans by applying a force to tissue in an amount to create a wound; applying a lathyrogenic agent to the wound; forming the wound into a predetermined stationary or moveable beneficial configuration; and maintaining the wound in the predetermined configuration and in contact with lathyrogenic agent during healing.
Claims28
A method of controlling scar formation in humans comprising:
- a) applying a force to tissue in an amount to create a wound;
- b) applying a lathyrogenic agent to the wound;
- c) forming the wound into a predetermined stationary or moveable beneficial configuration;
- and
- d) maintaining the wound in the predetermined configuration and in contact with lathyrogenic agent during healing.
A method of treating tubular organ stenosis in humans comprising:
- a) forcefully stretching a fibrotic lesion located inside a tubular shaped human body portion to tear existing scar tissue in the lesion and create a new wound;
- b) applying B-aminopropionitrile fumarate onto a catheter;
- c) inserting the catheter into the tubular body portion for a distance to cause B-aminopropionitrile fumarate/wound contact, thereby initiating softening of the wound;
- and
- d) retaining the catheter in place to continuously maintain the wound in a stretched condition so that the body portion will substantially retain the size of the catheter.
A method of reshaping scar tissue in humans comprising:
- a) stretching scar tissue in an amount to increase flexibility and lengthen or expand the tissue by exposing normal tissue;
- b) holding the flexible scar tissue in a desired shape;
- c) applying a lathyrogenic agent to the flexible scar tissue to soften the healing tissue;
- and
- d) simultaneously, maintaining the softened, flexible
- scar tissue in the desired shape during healing.
A method of controlling scar formation in humans comprising:
- a. applying a force to substantially tubularly shaped tissue in an amount to create a wound, wherein the tissue is selected from the group consisting of urethra, esophagus, intestine, fallopian tubes and blood vessels;
- b. applying a lathyrogenic agent to the wound;
- c. forming the wound into a predetermined beneficial configuration;
- and
- d. maintaining the wound in a predetermined configuration and in contact with lathyrogenic agent during healing.
A method of controlling scar formation in humans comprising:
- a. applying a force to substantially tubularly-shaped tissue in an amount to create a wound;
- b. applying a lathyrogenic agent to the wound, wherein the lathyrogenic agent is placed on a catheter and the catheter is inserted into the tubularly-shaped tissue to a point where the lathyrogenic agent directly and closely contacts the wound;
- c. forming the wound into a predetermined beneficial configuration;
- and
- d. maintaining the wound in a predetermined configuration and in contact with lathyrogenic agent during healing.
A method of controlling scar formation in humans comprising:
- a. applying a force to substantially tubularly shaped tissue in an amount to create a wound;
- b. applying a lathyrogenic agent to the wound;
- c. forming the wound into a predetermined beneficial configuration;
- and
- d. maintaining the wound in a predetermined configuration and in contact with lathyrogenic agent during healing.
