Arriyan Samandar Dowlatshahi has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11266373
    Abstract: The present invention relates to devices and methods for measuring vascular deficiency using Doppler ultrasound detection. Embodiments can be used to monitor the condition of surgical tissue flaps or other conditions in which obstruction in the vascular system can impact patient health. The systems can include a Doppler ultrasound probe, a color probe, a temperature probe, and/or other suitable probes to measure blood volume and perfusion status of a tissue region. The systems and methods can be used to monitor flaps after flap transplant surgeries. The systems and methods can automatedly assess tissue condition and alert the patient or medical staff if the condition has fallen below a threshold indicating occlusion of a blood vessel. One or more additional sensors can be integrated into a probe to measure vascular conditions and a metric can be computed based on sensed data.

  • Patent number: 10624622
    Abstract: A surgical appliance includes a pair of opposed prongs slideably disposed on an elongated locking track for retracting neurovascular and musculotendinous anatomical structures through an incision for affording access to deeper structures for inserting osteosynthesis hardware in the surgical treatment of a distal radius fracture or other surgical procedure. The prongs extend from retractors that traverse the locking track for opposed linear movement while recessed in a surgical working region accessible through an incision. The prongs terminate in curvatures defining a void that gather and engage the elongated anatomical structures on top of the skeletal members receiving the plate. The prongs draw back the tendons, blood vessels and nerve structures to allow unimpeded surgical access for manipulating and attaching skeletal and soft tissue members and/or appliances.
