Abstract
The present invention relates to a system and method for pulse cycle pressure modulation and negative pressure therapy in a cardio synchronous manner to improve distal limb blood flow applying negative or variable pressure to a portion of the body. The invention relates to methods and apparatus for the application of a sequential and gradient pulse wave for treating wounds that are difficult to heal or livelihood limiting claudication and/or ischemic rest pain. An integral part of the present invention includes methods to determine blood flow and effects of treatments on tissue.
Claims19
An apparatus for pulse cycle pressure modulation and negative pressure therapy treatment of a limb of a mammal comprising a pneumatic system for exerting negative pressure upon a tissue of the limb of the mammal which pressure is synchronized with a transduced real time signal representative of the mammal's cardiac cycle.
A method for pulse cycle pressure modulation and negative pressure therapy, wherein at least one of the following steps is performed simultaneously or sequentially:
- (i) applying positive pressure at a limb during systole;
- (ii) applying negative pressure at a wound site during systole;
- (iii) applying positive pressure at a tissue site on the limb during diastole.
A method of treating a wound of a vertebrate organism comprising the steps of (a) detecting cardiovascular activity of the organism;
- (b) applying varying sub-atmospheric pressures to a wound site of the organism in timed relation with the detected cardiovascular activity.
A method of treating one or more of the following human conditions:
- peripheral arterial obstructive disease;
- microangiopathy;
- vasculitis;
- vasa vasorum disease;
- complex regional pain syndrome;
- frostbite;
- erythromelalgia;
- trauma induced limb wound;
- chronic limb wound;
- diabetic neuropathic wounds;
- trench foot;
- Raynaud's disease;
- vasa nervosum disease;
- peripheral neuropathy;
- and peripheral arterial diseases in which traditional or standard treatments are contraindicated or not advised;
- by the steps of (a) detecting cardiovascular activity of the human;
- (b) applying varying sub-atmospheric pressures to one or more somatic sites on the human in timed relation with the detected cardiovascular activity.
