Electrostatic soft tissue wound repair enhancement
| Details |

Assignee: Hoffmann-La Roche Inc. (Nutley, NJ)
Primary Examiner: Cohen; Lee S.

Attorney, Agent or Firm: Saxe; Jon S., Gould; George M.
Electrostatic soft tissue wound repair enhancement is provided by means of a self-contained, non-invasively applied bandage arrangement comprising one or more electret elements each providing a small electrostatic field to the particular wound area. The self-contained, wafer-thin bandage may take the form of a sterile, disposable self-adhering band-aid like structure, a surgical sponge or a closely fitting article of clothing. |

DETAILED DESCRIPTION It is, therefore, the principle object of this invention to overcome the aforementioned drawbacks of the prior art and also provide the above-indicated desirable features, particularly in regard to soft tissue repair.
The principle objective of this invention is accomplished, and the approach of soft tissue wound repair enhancement made more universally applicable, by a device providing a self-contained electrostatic field for aplication directly to damaged tissue at virtually any anatomical site.
According to the broader aspects of the invention, there is provided a method for promoting soft tissue wound healing comprising applying non-invasively and in close proximity to a soft tissue wound site of an organizm an electret providing an electrostatic field to the wound site.
Also according to the invention there is provided apparatus for enhancing the natural healing process of a soft tissue injury of an organism comprising a base intended for placement upon a portion of the organisms's anatomy which has sustained a soft tissue injury and including means for securing the base to the organism, and electret means mounted on said base for non-invasive placement proximate the injury for providing an electrostatic field at the injury location.
The device of the invention is particularly characterized by incorporating the electret into a self-sticking (adhesive) bandage or a surgical type sponge.
Such a device enables a long-term electrostatic field source to be conveniently available for the soft tissue repair procedure, and is in sterilizable, disposable form.
By the invention, the electret element replaces and makes obsolete the need for batteries, electronic circuits, encapsulating material etc.
The invention further obviates the need for any surgery or implantation of any electrodes, and the like, by providing, rather, the application of an electret-fitted, self-adhering bandage enabling simple and effective treatment in the form of soft tissue wound repair enhancement
