The metering apparatus including: a metering chamber for accommodating a reprocessing fluid, wherein the metering chamber comprises: an inlet for letting the reprocessing fluid into the metering chamber; and an outlet for letting out the reprocessing fluid introduced into the metering chamber, wherein the inlet and the outlet are dimensioned such that a flow velocity of the reprocessing fluid from the outlet while the reprocessing fluid is being let out of the metering chamber is greater than a flow velocity of the reprocessing fluid into the inlet while the reprocessing fluid is being introduced into the metering chamber. | 2015-11-12 |
20150320506 | Millimeter-sized recognition signal badge and identification system for accurately discerning and sorting among similar kinds, shapes, and sizes of surgical instruments - The present invention is a discrete signal-identifying badge and operative system for recognizing, differentiating and distinguishing among the many kinds, shapes and sizes of surgical instruments and tools commonly used today for human and veterinary surgeries and in scientific research. The signal-identifying badge is a discrete millimeter-sized article of manufacture which can be easily affixed to an exposed surface of any type, any configuration and any dimension of surgical instrument or tool; and includes a well-cushioned and protected photovoltaic cell-integrated chip transponder unit embedded within a safeguarding three-tier stack construct. The photovoltaic cell of the embedded transponder is activated by the introduction of light energy in any form; and once activated, provides electric power to the electronic circuitry of the transponder unit of the instrument-affixed badge such that a responsive identifying RF signal is emitted to the ambient atmosphere. That emitted responsive identifying RF signal is detected and decoded by a remotely located reader; and then translated into readable form on a display for human visualization and acknowledgement. | 2015-11-12 |
20150320507 | PATH CREATION USING MEDICAL IMAGING FOR PLANNING DEVICE INSERTION - Efficient path planning of a medical device for insertion into a patient using medical imaging is provided. An image rendered from different transfer functions is used. One transfer function provides context, such as rendering to show a skin surface or other patient anatomical system. Another transfer function indicates local vessel, fluid, or other information for selecting points along the path. The user may select the transfer function used at different locations as well as the depth of a clipping plane at the different locations to allow unambiguous selection of a path point in the three-dimensional rendering. | 2015-11-12 |
20150320508 | Patient-Modified Implant - An orthopedic implant includes a first portion including at least one feature modified to be patient-specific and match the anatomy of a specific patient from a three-dimensional digital image of a patient's joint using computer modeling. The orthopedic implant includes a non-custom inner bone-engaging surface including a plurality of planar surfaces configured for engagement with non-custom bone cuts. | 2015-11-12 |
20150320509 | System and Methods for Percutaneous Treatment Planning and Treatment Monitoring - The present teaching relates to surgical procedure assistance. In one example, a first image of a patient captured prior to a surgical procedure is received. A treatment plan is generated based on the first image. The treatment plan includes information related to one or more surgical instruments. A second image of the patient captured after the surgical procedure has been initiated is received. The treatment plan is dynamically adjusted based on a pose of any of the one or more surgical instruments identified from the second image. A third image of the patient captured after a lesion is treated by at least one of the surgical instruments based on the adjusted treatment plan is received. Whether a further treatment to the lesion is needed is determined based on the third image. Upon determining a further treatment is needed, an updated treatment plan is dynamically generated based on the third image. | 2015-11-12 |
