Abstract: A lattice or solid structure for a medical device includes a first layer of first filaments discretely formed from at least one medical-grade silicone material. The first filaments are arranged in a predetermined pattern and may be directly adjacent to one another or spaced apart. Additional layers of filaments may be provided adjacent to the first layer, and chemically bonded thereto to form an integrated structure that is without interruption or with interstices therebetween.

Abstract: A prosthetic liner includes a textile cover having at least first and second regions having different elongation from one another. The first region is in a prestretched configuration in at least one orientation relative to an axis of the prosthetic liner and locked in the prestretched configuration according to a layer of elastomeric material located along a surface of the textile cover.

Abstract: A system for additive manufacturing a medical device, the system comprising a first dispensing system, a second dispensing system, a deposition apparatus, and a deposition substrate on a surface of which the deposition apparatus is configured to deposit at least one elastomeric material into a filament. The deposition apparatus receives the at least one elastomeric material from the first and second dispensing systems in proportions effecting a desired property in the medical device. The deposition apparatus may comprise heating and/or cooling elements, a sonic vibration module, and/or a pneumatic suck-back valve. The deposition substrate may have a configuration corresponding to a desired shape of the medical device and is configured to rotate and/or translate relative to the deposition apparatus. The system comprises a controller configured to control the deposition.

Abstract: A system and method associated with the movement of a limb. In one example, the system, such as a prosthetic or orthotic system, includes an actuator that actively controls, or adjusts, the angle between a foot unit and a lower limb member. The actuator preferably selectively locks during a desired phase in a gait cycle of the limb and minimizes friction against a rotor of the actuator. A processing module may control movement of the actuator based on data obtained from a sensor module. For instance, sensing module data may include information relating to the gait of a user and may be used to adjust the foot unit to substantially mimic the movement of a natural, healthy ankle. The system may further accommodate, for example, level ground walking, traveling up/down stairs, traveling up/down sloped surfaces, and various other user movements. In addition, the processing module may receive user input or display output signals through an external interface.

Abstract: A system and method for sensing movement of a device associated with a limb. In one example, a prosthetic or orthotic system includes a sensor assembly configured to measure movement of a component of the system in a single direction while substantially isolating negative effects of forces and/or loads in other directions. For instance, the sensor assembly may be advantageously coupled to a pivot assembly configured to substantially mimic a natural ankle joint. The sensor assembly may monitor rotation of a foot unit about an axis of a pivot pin of the pivot assembly and disregard other movements and/or forces. For example, the sensor assembly may include a potentiometer that detects rotation of an associated elongated bellow portion about the axis, wherein the bellow portion includes a plurality of ridges configured to substantially eliminate effects of radial and/or axial forces.
