  • Patent number: 11766343
    Abstract: An apparatus for adjusting an expandable prosthetic device includes: an elongated main support having a longitudinal axis and a distal end, and being adapted to connect to an outer or inner side of an adjustable socket having a distal end; an adjustable cup adapted to connect to the distal end of the elongated main support and having an expandable base and at least one side adapted to move laterally toward or laterally away from the longitudinal axis of the elongated main support; and at least a portion of a suspension system disposed in the adjustable cup and having a top adapted to connect to the distal end of the adjustable socket and a bottom adapted to slidably connect to the expandable base of the adjustable cup.

  • Patent number: 11382775
    Abstract: An adjustable prosthesis system for a residual limb includes: an adjustable outer shell surrounding the residual limb having a plurality of overlapping flaps, a top opening along a top edge extending around the outer shell, a bottom having a bottom edge opposite the top edge and extending around the bottom, a first side, and a second side having an adjustable width, and a plurality of adjustable overlapping side ends, some of which overlap and some do not, extending from the top edge to the bottom edge; a base adjacent the bottom of the outer shell and connected to it; and a closure component attached to the outer shell to compress the residual limb. Tightening the closure component applies a pulling force to at least one of the first side and the second side, thereby causing a reduction in width of a discontinuity and increased overlap of the side ends.

  • Patent number: 10806608
    Abstract: A method of placing a prosthetic system over a residual limb, said method comprising the steps of: providing the prosthetic system; and placing an outer shell of the prosthetic system on the residual limb having an above-knee amputation, the outer shell at least partially surrounds the residual limb, an outer side and an inner side of the outer shell on opposite sides of the residual limb, an upper edge of the outer side above a greater trochanter, the inner side below a lowest edge of an ischium without being directly below the lowest edge of the ischium.

  • Patent number: 8491667
    Abstract: A modular prosthesis system that can be inexpensively manufactured using modern technology and advanced polymer materials. The modular prosthesis system will be immediately fit on the residual limb and aligned for optimal gait without specialized tools or labs, alleviating the many steps involved with conventional labor-intensive and costly prosthesis construction. The modular prosthesis system also accommodates the changing in size and shape of the limb, eliminating the need for multiple prostheses and adjustments to an existing prosthesis during the lifetime of an amputee.
