Abstract: In an example embodiment, an optical communication system includes an implantable optical transmitter and an external optical receiver. The transmitter includes a housing having one or more drivers, plural light emitting sources, and an optical element arranged therein. Each driver converts a digital data signal into modulation signals to drive the sources. Each source generates a light beam in response to a corresponding modulation signal, each light beam contributing to form a single optical signal. The optical element directs the light beams to exit the housing such that a peak position of light intensity of each light beam is separated from a corresponding peak position of light intensity of an adjacent light beam by at least a first distance and less than a second distance. The optical receiver includes at least one photodiode that detects light generated by the sources and generates a reconstructed data signal.

Abstract: Nozzle system for a powder blasting device including a first nozzle element for transporting a powder-gas mixture stream along a transporting direction and a second nozzle element, where the second nozzle element surrounds the first nozzle element such that at least one channel is formed between the first nozzle element and the second nozzle element, where the channel is provided for transporting a liquid stream, where the first nozzle element and the second nozzle element are arranged such that in operation the powder-gas-mixture stream ejected by the first nozzle element is encased by the liquid stream ejected by the channel for forming an output stream of the nozzle system, where the first nozzle element has an acceleration part having a first cross section and a spreading part having a second cross section, where the spreading part is arranged downstream of the acceleration part.

Abstract: An implantable device includes a low-profile housing having a cavity defined in a side thereof, and an element insertably removable with respect to the housing in a direction substantially parallel to a surgical plane of the implantable device. The element has a first portion adapted to be received in the housing cavity. The element further includes a second portion adapted to protrude from the housing upon insertion of the element into the housing cavity. The second portion includes at least one surface adapted for engagement with a surgical instrument for insertion and removal of the element with respect to the housing. A method for servicing the implantable device includes, at an incision proximate an implant location of the implantable device, insertably and removably accessing the element in a direction substantially parallel to a surgical plane of the implantable device.

Abstract: Lipoaspirate can be treated for use in fat grafting procedures. For example, the lipoaspirate can be placed in a container having an inlet for receiving the lipoaspirate and an outlet for dispensing and removal of desired materials from the lipoaspirate. The inlet and the outlet can be located on a common side of first and second filter elements. An activation mechanism can be actuated to move the first filter element relative to the second filter element within the container to separate cellular components of the lipoaspirate from non-cellular components of the lipoaspirate.

Abstract: Methods and devices for treating lipoaspirate for use in fat grafting procedures are provided and generally include a canister for containing lipoaspirate, a separation mechanism structured to separate both oils and other materials from cellular components of lipoaspirate contained in the canister. The separation mechanism includes filters having different filtering capacities, for example, different pore sizes.

Abstract: A transorally implanted intragastric balloon or treating obesity and for weight control including a variable size balloon with one or interconnected regions acting to exert a pressure on the stomach, to provide a stomach volume occupying effect, and/or to anchor the balloon within the stomach.

Abstract: A mechanism for removing a fluid-filled object such as an intragastric balloon from a patient. The apparatus includes a delivery tube having a lumen and a retrieval tool able to slide within the lumen that can both puncture and grasp the intragastric balloon. The retrieval tool may have sharpened graspers with either a sharp tip and/or knife-like edges. Alternatively, the delivery tube itself may have sharpened cutting blades that deploy outward to puncture the intragastric balloon. One embodiment utilizes a suction cup tip on the delivery sheath and a sharpened puncture rod that extends past the distal tip of the lumen, for rapid deflation of a balloon. Various embodiments hasten the deflation process and simplify the manipulation required by the surgeon.

Abstract: A remotely adjustable remotely power gastric band system may include a control device, an implant electronic device, and an implantable gastric band. The control device may telemetrically power and communicate with the implant electronic device, which may be used for adjusting the diameter of the implantable gastric band. The implant electronic device may store the gastric band adjustment history records of a patient and regulate the power received from the control device. To improve transmission efficiency, the implant electronic device may adopt a double modulation scheme for communicating with the control device. Furthermore, the implant electronic device may detect and resolve motor blockage issues related to the implantable gastric band.
