A system and method for producing a customized prosthetic socket based on a digital representation of a residual limb that is used to form a digital model of a prosthetic socket. The digital model is customized to alter its internal structure to produce differing areas of flexibility and support while maintaining the overall geometry of the model and without having to use different materials. The digital model is converted for use with a three-dimensional printing or manufacturing device and then used to print the customized socket.

A flexible inner socket is fabricated by forming a pre-socket. The pre-socket includes a body formed with an opening and an enclosed end. The enclosed end is opposite to the opening. The body of the pre-socket has an outer circumference that is smaller than the inner circumference of the rigid prosthetic socket. Different portions of the body may have different thicknesses. The preform socket is heated. After the heating, the flexible inner socket is formed by molding the pre-socket onto the inner surface of the rigid prosthetic socket to form the flexible inner socket. The inner circumference of the rigid prosthetic socket is reduced by a thickness of the flexible inner socket when the flexible inner socket is attached to the inner surface of the rigid prosthetic socket. An opening of the flexible inner socket may be trimmed after the formation to fit contours of an opening of the rigid prosthetic socket.

A sheath made of an elastomer material for a prosthesis liner comprises an inner wall and an outer wall defining a sheath body that extends between a proximal end suitable for placing the sheath body onto a stump and a distal end. The sheath is provided at the distal end thereof with a conformable cavity that is formed in the sheath body and is open to the outside via an opening.

The invention relates to a method for creating a 3D scan of a body part, the method comprising the following steps: a. Molding a contact element to the body part, b. Capturing a first partial scan of the body part, c. Removing the body part from the contact element, d. Capturing a second partial scan of the contact element, and e. Creating the 3D scan at least also from the first partial scan and the second partial scan.

A prosthetic foot including a continuous body extending from a proximal end to a distal end. The body includes an anterior surface, a posterior surface opposite the anterior surface, and a fin on the posterior surface. A prosthetic foot can include a first footplate and a second footplate. The first footplate extends between a proximal portion and a distal portion. The proximal and distal portions of the first footplate are configured to operatively engage a support surface during ambulation. The second footplate extends between a proximal portion and a distal portion. The distal portion of the second footplate is coupled to the first footplate at an intermediate location between the proximal and distal portions of the first footplate. The second footplate incudes an anterior surface, a posterior surface opposite the anterior surface, and a fin on the posterior surface.

A support structure, a prosthesis component, and a method for producing a prosthesis component.

A suspended sleeve assembly includes a suspension stand and a compression sleeve. An upper portion of the compression sleeve is attached onto the suspension stand, but a lower portion of the compression sleeve is unattached from the suspension stand. The suspended sleeve assembly can also include a support stand. The suspended sleeve assembly can be used to shape a prosthetic socket. The compression sleeve applies a circumferential pressure onto the prosthetic socket as the prosthetic socket is being inserted into the compression sleeve as a patient steps into the compression sleeve and applies at least a portion of body weight to the compression sleeve. The prosthetic socket can be heated and shaped by hand, so that it fits the residual limb of the patient. The suspended sleeve assembly can also be used to shape other prosthetic components, such as a negative plaster cast.

A suspension liner has a liner body portion, a textile material, and a plurality of seals formed along a length of the suspension liner toward a closed distal end and protruding circumferentially about a liner profile. Each seal has a same shape including a peak having a rounded profile and a width narrowing toward the peak and defines a sealing surface arranged to form a secure interface with an interior wall of the socket that retains the suspension liner within the prosthetic socket. The textile material is located intermediate interior and exterior surfaces of the suspension liner that formed of one or more silicone materials in the area of the seals and the textile material defines the exterior surface of the suspension liner proximal and distal to the seals.

An interchangeable lock-pump prosthetic system that includes a universal dummy, vacuum pump, and mechanical lock. Each of the three objects have similar geometries for the purpose of fitting into a prosthetic, whereupon a user may for instance, swap the vacuum pump with the lock, depending on the needs of the user and without changing to a separate prosthetic. The universal dummy is an inactive component and acts as a placeholder during manufacturing of the socket, for the eventual inclusion of the vacuum pump or mechanical lock. The vacuum pump is a pressure dependent object that acts to remove any residual air between the socket and the elastomeric liner. The lock takes advantage of a mechanical locking pin which receives a properly configured liner, thus securing the user within the prosthetic socket.

An apparatus for suspending a prosthesis from a residual limb comprises a tubular liner adapted to receive the residual limb. A lanyard is secured at one end to the distal end of the liner. A hollow prosthetic socket defines a well configured to receive the residual limb and includes a socket seal disposed at the distal end of the socket. An upper surface of the socket seal defines a recess opening to the exterior of the socket through a side wall. A sealing element disposed along the length of the lanyard is configured to engage within the passage. The free end of the lanyard is pulled through passage such that the sealing element sealingly engages within the passage for preventing fluid communication through the passage. The liner at least partially contacts the interior surface of the socket for providing a fluid seal and creating negative pressure within the socket.
