  • Publication number: 20240123222
    Abstract: A functional electrical stimulation (FES) device includes electrodes arranged to apply functional electrical stimulation to a body part of the user. FES stimulation is performed by: receiving values of a set of user metrics for the user; receiving a target position of the body part represented as values for a set of body part position measurements; determining a user-specific energization pattern for producing the target position based on the received target position and the received values of the set of user metrics for the user; and energizing the electrodes of the FES device in accordance with the determined user-specific energization pattern. The determination may utilize an FES calibration database with records having fields containing: values of the set of user metrics for reference users; energization patterns; and values of the set of body part position metrics for positions assumed by the body part in response to applying the energization patterns.

  • Patent number: 7604647
    Abstract: A cannula insertion tool having a needle movable between a retracted position and an extended position. In some embodiments, the needle can be retracted within the periphery of a handle of the insertion tool when not in use to protect the needle. When the needle is needed for surgical use, the needle can be extended at least partially beyond the outer periphery of the handle. The needle can be coupled to a slide movable relative to the handle between the retracted position and the extended position. The slide can be secured in each position to prevent unintentional movement of the slide. A cannula can be positioned on the needle when the needle is in the retracted position, and can be retained upon the needle by a member extending toward the cannula.

  • Publication number: 20040224608
    Abstract: An attachable breast form enhancement system comprising a pair of breast forms adjoined by a connector. The breast forms have an interior surface with a pressure sensitive adhesive layer that adjoins to the user's breasts. The pressure sensitive adhesive layer can be a permanently grown pressure sensitive adhesive that has an adhesion force to the breast forms that is greater than a cohesion force to the user's breasts. The connector adjoins the separated breast forms by attaching to the inner sides of the breast forms and pulling the user's breasts together. The connector can be either permanently or removably attached to the breast forms. Several different configurations of breast forms and connectors are available to achieve the benefits of the present breast form system. The improved breast form system allows a user to eliminate use of traditional bras by simply adhering the pair of breast forms to the user's breasts/skin, and then adjoining the breast forms with the connector.
