The tensioning assembly includes a first modular coupling element, a second modular coupling element, and at least one spring element positioned between the coupling elements to generate adjustable force along an axis. A retention mechanism, positioned above the first skin-contacting assembly, comprises a body portion with openings for threading elastic cords and a central opening for alignment along the axis. The device further includes modular coupling means enabling detachable and interchangeable connections between the components, allowing customization of the configuration. The first skin-contacting assembly is adjustable in tension and orientation via elastic cords, and the first and second skin-contacting assemblies are configured for angular and positional adjustment relative to the axis, accommodating variations in user anatomy. ## Claims ### Claim 1 A modular foreskin restoration device, comprising: a first skin-contacting assembly configured to secure a portion of the foreskin, the first skin-contacting assembly comprising inner and outer gripping elements and including a first coupling means; a second skin-contacting assembly positioned in spaced relation to the first skin-contacting assembly, the second skin-contacting assembly comprising a contact surface configured to engage with the glans of a user; a tensioning assembly disposed between the first skin-contacting assembly and the second skin-contacting assembly, the tensioning assembly comprising: (i) a first modular coupling element positioned at one end of the tensioning assembly; (ii) a second modular coupling element positioned at an opposite end of the tensioning assembly; and (iii) at least one spring element positioned between the first and second modular coupling elements and operable to provide an adjustable force along an axis between the first and second skin-contacting assemblies; a retention mechanism disposed above the first skin-contacting assembly, the retention mechanism comprising: a body portion with a plurality of openings positioned about its outer circumference for threading elastic cords; and a central opening for aligning with the axis; a modular coupling means operable to detachably connect the first skin-contacting assembly, the second skin-contacting assembly, the tensioning assembly, and the retention mechanism, wherein the modular coupling means permits interchangeability of components within the device; wherein the elastic cords are threaded through the openings in the retention mechanism and the top of the first skin-contacting assembly and are adjustable in length to modify the tension applied to the foreskin and the orientation of the first skin-contacting assembly with respect to the axis; and wherein the first and second skin-contacting assemblies are each configured to allow relative angular and positional adjustment with respect to the axis. ### Claim 2 (depends on 1) The foreskin restoration device of claim 1, wherein the first skin-contacting assembly comprises an inner and an outer gripping element, the inner and outer gripping elements being concentrically arranged to secure the foreskin between them. ### Claim 3 (depends on 2) The foreskin restoration device of claim 2, wherein the inner and outer gripping elements are constructed from a flexible material. ### Claim 4 (depends on 1) The foreskin restoration device of claim 1, wherein the tensioning assembly further comprises a second spring element, the second spring element being combinable with the at least one spring element to provide an increased adjustable force. ### Claim 5 (depends on 4) The foreskin restoration device of claim 4, wherein the at least one spring element is a first spring having a first diameter and a first stiffness, and the second spring element has a second diameter and a second stiffness, the second stiffness being greater than the first stiffness. ### Claim 6 (depends on 1) The foreskin restoration device of claim 1, wherein the retention mechanism comprises a central threaded opening and is operable to adjust the axial position of the retention mechanism relative to the first skin-contacting assembly. ### Claim 7 (depends on 6) The foreskin restoration device of claim 6, further comprising a threaded rod inserted through the central threaded opening, the threaded rod being operable to control the distance between the retention mechanism and the first skin-contacting assembly. ### Claim 8 (depends on 6) The foreskin restoration device of claim 6, wherein the retention mechanism is configured to allow substitution of the threaded rod with a spacer element of fixed length. ### Claim 9 (depends on 1) The foreskin restoration device of claim 1, wherein the modular coupling means comprises a set of interlocking fasteners selected from the group consisting of threaded connectors, snap-fit connectors, and bayonet connectors. ### Claim 10 (depends on 1) The foreskin restoration device of claim 1, wherein the retention mechanism comprises a plurality of openings distributed radially about its outer circumference, the openings being configured to allow elastic cords to be threaded through. ### Claim 11 (depends on 10) The foreskin restoration device of claim 10, wherein the elastic cords are adjustable in length to modify the tension applied to the foreskin and the orientation of the first skin-contacting assembly. ### Claim 12 (depends on 1) The foreskin restoration device of claim 1, wherein the second skin-contacting assembly comprises a concave surface configured to conform to the glans of a user. ### Claim 13 (depends on 1) The foreskin restoration device of claim 1, wherein the modular coupling means permits the substitution of alternative tensioning assemblies, each alternative tensioning assembly comprising a different tensioning mechanism. ### Claim 14 (depends on 1) The foreskin restoration device of claim 1, wherein the housing of the tensioning assembly is configured to accommodate springs of varying lengths to enable customization of the tensioning force. ### Claim 15 (depends on 1) The foreskin restoration device of claim 1, wherein the at least one spring element is a compression spring. ### Claim 16 (depends on 1) The foreskin restoration device of claim 1, wherein the tensioning assembly further comprises a guiding structure configured to maintain alignment of the at least one spring element along the axis. ### Claim 17 (depends on 1) The foreskin restoration device of claim 1, wherein the first skin-contacting assembly further comprises a foreskin alignment ridge positioned to assist in securing the foreskin. ### Claim 18 (depends on 1) The foreskin restoration device of claim 1, wherein the second skin-contacting assembly further comprises an air pad positioned adjacent to the contact surface. ### Claim 19 (depends on 1) The foreskin restoration device of claim 1, wherein the device is configured to be worn discreetly under clothing, with the retention mechanism and the first and second skin-contacting assemblies being compact in size. ### Claim 20 (depends on 1) The foreskin restoration device of claim 1, wherein the first skin-contacting assembly is detachably coupled to the retention mechanism via a Velcro fastener, a friction fit, or an adhesive material, enabling ease of assembly and disassembly.
