This arrangement aids easy assembly of the electrostimulation device especially when using a unitary device body to form a self-contained device. The device may be arranged to deliver constant target current to a muscle for electro-stimulation of that muscle. The device may be a completely self-contained device with no external means for the adjustment and control of the electro-stimulation delivered to the muscle during treatment. The microprocessor based device may monitor indirectly the actual current delivered to the muscle during electro-stimulation via measurement of the return path voltage through the muscle and optionally in addition monitors and adjusts for the internal battery voltage during use of the device in order to deliver a more consistent an accurate and effective target output current to the muscle being stimulated at each and every pulse delivered from the device. ## Claims ### Claim 1 A compressible electro-stimulation device comprising a compressible body with at least one electrode at or on the device body surface and corresponding numbers of electrode connectors internal to the body, wherein each electrode and its corresponding electrode connector remain separated from each other upon completed assembly of the device and are adapted to contact with each other and to lockingly engage with each other upon compression of the device body. ### Claim 2 (depends on 1) A device as claimed in claim 1, wherein the compressible body is a unitary compressible body. ### Claim 3 (depends on 1) A device as claimed in claim 1, wherein the electrode or the electrode connector comprises a female connector. ### Claim 4 (depends on 3) A device as claimed in claim 3, wherein the female connector comprises an elongated chamber. ### Claim 5 (depends on 1) A device as claimed in claim 1, wherein the electrode or the electrode connector comprises a male connector. ### Claim 6 (depends on 1) A device as claimed in claim 1, wherein the electrode comprises a female connector and the electrode connector comprises a male connector. ### Claim 7 (depends on 6) A device as claimed in claim 6, wherein the electrode comprises a female connector over molded with electrode material. ### Claim 8 (depends on 6) A device as claimed in claim 6, wherein the female and male connectors snap-fit to each other via an internal locking ridge on the female connector and an external locking ridge on the male connector. ### Claim 9 (depends on 1) A device as claimed in claim 1, wherein the electrode and electrode connector are in sliding locking engagement with each other. ### Claim 10 (depends on 1) A device as claimed in claim 1, wherein the electrode and electrode connector are in engagement with each other and may move one relative to the other upon compression of the device. ### Claim 11 (depends on 1) A device as claimed in claim 1, further comprising a sub-assembly. ### Claim 12 (depends on 11) A device as claimed in claim 11, wherein the sub-assembly comprises guide elements protruding from a sub-assembly housing. ### Claim 13 (depends on 12) A device as claimed in claim 12, wherein the sub-assembly comprises electrode connectors having connector ends in fixed attachment to the sub-assembly. ### Claim 14 (depends on 13) A device as claimed in claim 13, wherein the sub-assembly comprises a proximal and distal end and the electrode connectors are fixed to the sub-assembly at its proximal end. ### Claim 15 (depends on 13) A device as claimed in claim 13, wherein the sub-assembly comprises a proximal and distal end and two electrode connectors one fixed to the sub-assembly at its distal end and the other fixed to the sub-assembly at its proximal end. ### Claim 16 (depends on 1) A device as claimed in claim 1, wherein the body comprises a distal end access point for insertion of a sub-assembly. ### Claim 17 (depends on 16) A device as claimed in claim 16, wherein the distal end access point and the sub-assembly are arranged such that their smallest cross-sectional dimension is aligned with an axis between the device electrodes. ### Claim 18 (depends on 1) A device as claimed in claim 1, further comprising an internal sub-assembly aligned within the device body such that its smallest cross-sectional dimension is aligned with an axis between the device electrodes.
