  • Patent number: 10987211
    Abstract: Devices, systems, and methods of the present disclosure are directed to efficient and accurate removal of tissue from a three-dimensional anatomic structure, such as a breast, of a patient. For example, a cup can be positioned on the patient's breast to conform the breast (e.g. via suction) to a known three-dimensional contour, and a cutting tip can be moved along the three-dimensional contour at one or more predetermined distances from at least one surface of the cup. The cutting tip can remove tissue along the three-dimensional contour to form a skin envelope. As compared to a manual process performed by a surgeon, formation of the envelope through controlled movement of the cutting tip along the three-dimensional contour can improve control over dimensions of the envelope, thus, facilitating achievement of consistent outcomes by reducing the likelihood of complications associated with an envelope that is too thick, too thin, or uneven.

    Abstract: A triple flap nipple reconstruction is shown with preoperative incision markup lines guided by a template. The incision lines made on a patient's skin rims of flaps that are to form a reconstructed nipple. The marked-up lines define three flaps where each flap has one side in common with each of the other two flaps and also has one side in common with a part of the skin which is to be removed or de-epithelized. Also, the marked-up lines define parts of the patient's skin to be removed or de-epithelized. The surgical method thus consists of making the markup with the template with three single pedicled local dermal-fat flaps from the patient's skin and then de-epithelizing designated areas of the patient's skin, making incisions and forming, i.e., raising three flaps, forming base and elevating nipple by joining sides of de-epithelized areas, and jointing the three flaps.

  • Patent number: 10953143
    Abstract: The present invention features methods of manipulating subdermal fat in a treatment area. Such methods include inserting a needle (e.g., a micro-coring needle) through the dermis to the subdermal fat layer in order to excise a portion of tissue from the treatment area. These insertions result in a portion of the dermis and a portion of subdermal fat to enter into the needle. Removal of the needle results in excision of the portion of dermis and subdermal fat that entered into the needle.

  • Patent number: 10932811
    Abstract: A tissue-removing catheter includes a cutting element. A radially innermost portion of the leading radial wall of a raised element of the cutting element may be spaced a radial distance from the longitudinal axis that is less than 66% of the radius of the annular cutting edge. The cutting element may be extendable through the window during operation such that as the cutting element is being rotated about its longitudinal axis, less than an entire radial portion of the leading radial wall passes through the window. A plurality of abrading members may be formed on at least the central portion of the inner surface of the cutting element to abrade hardened tissue as the cutting element is rotating about its longitudinal axis. A radially outermost portion of the leading radial edge of the raised element may be spaced apart radially from an inner surface of the cutting element.

  • Patent number: 10925531
    Abstract: An infant peripheral lancing device having safety buckle turn lock and anti-backward push button, wherein the safety mechanism is a safety buckle rotationally connected on a housing, and the first occupation gesture of the safety buckle during movement is between a push button and the housing and locks the push button; the second occupation gesture is in unlocking position. The push button is set with a locking mechanism, which comprises a first locking part on the push button and a second locking part on the housing or the cam and when the push button is moved backward, the first locking part and the second locking part meet to form a locking state. This solution always connects the safety buckle and the housing to prevent an accidental disconnection or loss and the lancing device present invention locks the push button automatically after using to make it easy for the user to identify the state of the push button.
