Patents by Inventor Charles Colin Macduff

Charles Colin Macduff has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20190038436
    Abstract: The disclosure provides apparatus and methods of use pertaining to a biomechanical finger brace assembly. In one embodiment, the assembly includes a coupling tip, a proximal ring configured to concentrically receive a user's finger, a distal ring configured to concentrically receive the finger, and a rocker formed in an H-shape. The distal ring and the rocker are pivotally suspended between a proximal coordinated pivot point anchored on the proximal ring and a distal coordinated pivot point anchored on the coupling tip, such that movements of the finger within the proximal ring articulate the distal ring together with the rocker to articulate the coupling tip. The coupling tip may include an open end or an enclosed recess to accept a minimally-amputated or non-amputated finger. Other embodiments are also disclosed.

  • Publication number: 20180280160
    Abstract: The disclosure provides apparatus and methods of use pertaining to a prosthetic finger assembly. In one embodiment, the assembly includes a coupling tip and a distal ring coupled with the coupling tip. The assembly further includes a proximal ring coupled with the distal ring. A rocker formed in an H-shape with a first end forming a first split prong and a second end forming a second split prong may extend between the coupling tip and the proximal ring. The coupling tip, distal ring, proximal ring, and H-shaped rocker may all be hingedly connected such that movements of the residual finger within the proximal ring articulate the distal ring together with the rocker to articulate the coupling tip. Other embodiments are also disclosed.

  • Publication number: 20180200080
    Abstract: The disclosure provides apparatus and methods of use pertaining to a prosthetic finger assembly. In one embodiment, the assembly includes a coupling tip and a distal ring coupled with the coupling tip. The assembly further includes a proximal ring coupled with the distal ring. A rocker formed in a Y-shape with a first end forming a single prong and a second end forming a split prong may extend between the coupling tip and the proximal ring. The coupling tip, distal ring, proximal ring, and Y-shaped rocker may all be hingedly connected such that movements of the residual finger within the proximal ring and the distal articulate the distal ring together with the rocker to curl and bend the coupling tip. Other embodiments are also disclosed.

  • Patent number: 10016289
    Abstract: There is disclosed a biomechanically driven prosthetic thumb assembly. Embodiments include an H-shaped rocker and a distal ring configured to receive a user's residual thumb, the distal ring and the rocker each independently and rotatively coupled between a coupling tip and a proximal anchor plate configured for affixing to a hand strap secured to a user. The coupling tip is articulated in response to a pulling force of the H-shaped rocker. Additional embodiments include a bidirectional thumb assembly including a ring mounted upon an adjustable ring tendon that is rotatively coupled between a coupling tip and a proximal anchor plate, which is rotatively coupled with a hand strap attached to the user. Vertical movement of the residual thumb within the ring actuates the coupling tip within a vertical plane. Lateral movement of the residual thumb within the ring actuates the coupling tip within a lateral plane. Other embodiments are disclosed.

  • Patent number: 9855148
    Abstract: A skeletal replacement system may be utilized to replace bones in a patient. The skeletal replacement system has least one skeletal replacement linkage, each skeletal replacement linkage having a first member, a second member, and a hinge. The first and second members are hingedly coupled by the hinge. Multiple skeletal replacement linkages may be coupled end to end through a shaft on the second member of a first linkage being inserted into a bore in the first member of a second linkage. Each linkage is configured to replace at least a portion of each of two bones and a joint in a patient's body. Multiple linkages may be used to replace more bones and joints as required.

  • Patent number: RE46164
    Abstract: A prosthetic finger that is able to provide independent natural movement to mimic a real finger. The present invention utilizes unique connections to provide users with natural movement and restore their ability to perform activities that require the full dexterity of their hands. Additionally, the present invention also allows users to interact with touch screens that normally would not work due to the insulating properties of other traditional prosthetic fingers.
