Body worn apparatus and prosthetic

1. A method of assisting a living being with movement of a prosthetic device that is integrally formed with a wearable garment, comprising:

providing a substantially soft, pliable first apparatus substantially in the form of an article of clothing to be worn by an individual, the first apparatus including a prosthetic device secured thereto and having first and second portions secured together for cooperative movement of the first and second portions as well as a body interface secured to either the first or second portion to couple the prosthetic device to a body part of a user;

providing a plurality of hollow, tubular, elongate, substantially pliable, McKibbens artificial muscle type, incompressible hydraulic fluid activation elements arranged in at least one bundle of activation elements, the activation elements being anchored at opposite ends to the first and second portions of the prosthetic device respectively, the activation elements being arranged parallel in side-by-side relationship with respect to their lengths and capable of independent movement with respect to each other at least along their lengths when activated, each activation element of the bundle having a first predetermined diameter selected to provide a force density for the bundle of at least about two times greater than the force density enabled by any single one of an artificial muscle style hydraulic activation element that has a second diameter being at least five times greater than the first diameter;

providing an incompressible hydraulic fluid pump system for independent and selective activation of each activation element of the bundle separately or in any combination to vary a force applied by the bundle to the prosthetic device; and

activating a desired number of activation elements via the hydraulic fluid pump system so that the activation elements expand outwardly along their lengths to thereby contract longitudinally and provide a contraction force between the first and second portions of the prosthetic device to thereby move the first and second portions with respect to each other.

2. The method as defined in claim 1 wherein the elongate activation elements have a diameter between 0.4-0.8 CM so that the bundle of activation elements has about twice the force density of a single activation element having a diameter at least five times greater than the activation elements in the bundle.

3. A prosthetic device, comprising:

a first portion in the form of a first artificial body portion;

a second portion in the form of a second artificial body portion, the second portion being secured to the first portion for cooperative movement of the first and second portions;

a body secured to the first portion to couple the prosthetic device to a body part of a user;

a plurality of hollow, tubular, elongate, substantially pliable, McKibbens artificial muscle type, incompressible hydraulic fluid activation elements arranged in at least one bundle of activation elements, the activation elements being anchored at opposite ends to the first and second portions respectively, arranged parallel in side-by-side relationship with respect to their lengths and capable of independent movement with respect to each other at least along their lengths when activated, wherein each activation element of the bundle has a first predetermined diameter selected to provide a force density for the bundle of at least about two times greater than the force density enabled by any single one of an artificial muscle style hydraulic activation element that has a second diameter being at least five times greater than the first diameter; and

an incompressible hydraulic fluid pump system for independent and selective activation of each activation element of the bundle separately or in any combination to vary a force applied by the bundle to the first and second portions.

4. The actuator as defined in claim 3 , including a plurality of mechanical fluid valves wherein each activation element is independently activated and controlled by a mechanical fluid valve that is operational to at least completely shut off the flow of the incompressible hydraulic fluid regardless of a composition of the incompressible hydraulic fluid.
