Folding Transducer Array for Compact and Deployable Wave-Energy Guiding System
TS-043186 — A novel acoustic/ultrasonic wave-energy guiding system that utilizes structural topology to enhance directional and spectral sensitivities instead of phase delay, offering exceptional versatility and adaptable performance.
Although acoustic beamforming systems that are based on phase delays can be used to enhance directional and spectral sensitivities, each source or receiver must be individually controlled by appropriate phase delays to guide the acoustic energy radiation/reception sensitivities. This results in a …

High-strength and Corrosion Resistant Alloy for Patient-Specific Bioresorbable Bone Fixation Hardware
TS-042526 — Novel ternary and quaternary Mg-Zn-Ca-based alloys and a heat treatment process for producing bioresorbable bone fixation implants with improved mechanical and corrosion properties
Mg-Zn-Ca-based alloys are the most promising alloy system for bone implant applications mainly due to their superior biocompatibility. For fixation applications, the ideal is a material strong enough to hold while healing (2-4 months) yet being fully resorbed after the bones have healed (6-24 mont…

Junctional Tourniquet for Groin and Axillary Regions
TS-041808 — A tourniquet with a ratcheting lock to keep pressure on wounds in the groin and axillary regions. Hemostasis can be achieved while the patient is still in the field.
Patients with blood loss in the field need to be treated immediately to prevent ongoing blood loss, shock, and death; bleeding from extremity and junctional wounds is the leading cause of potentially preventable death from penetrating injuries. Direct manual pressure is effective for the initial c…

Nonadhesive Medical Tube Attachment Device
TS-041656 — A device that holds nasogastric tubes, oxygen nasal cannulas, and facial dressings without adhesive.
Nasogastric tubes are used to give patients food and medications. Current commercially available tube holders are adhesive devices that attach to the nose. The devices put pressure on the nose and have to be completely removed to check the skin underneath or to adjust the tubes. Oxygen nasal cannu…

Virtual image generation of immunohistochemical stained tissue sections using an artificial neural network
TS-039781 — Realistic immunohistochemical stained tissue section databases for training, certification, and machine standards.
Immunohistochemistry (IHC) is used to determine antigen distribution in a tissue and is widely used for diagnosis of cancers and other diseases. Diagnostic and research laboratories in the United States use locally devised IHC tissue slide preparation and scanning protocols to check scanner perfor…

Improved wound drainage receptacle
TS-039105 — Exudate drain receptacles that can be easily emptied and improve accuracy of measurements, while reducing exposure to exudate.
Surgical drains are used to aid in the evacuation of exudate from a surgical site. These drains commonly connect to a drainage receptacle that is maintained by clinical staff during the post-operative period. It is common practice for providers to order the receptacles to be emptied every eight ho…

Six Degrees-of-Freedom Quality Assurance Phantom for Radiation Therapy Linear Accelerators
TS-037968 — The medical physics group in the Department of Radiation Oncology has devised a 6DoF phantom that is the first of its kind to fully integrate multiple routine QA tests specifically for a six degrees-of-freedom linac table.
6DoF treatment tables allow for 2 additional degrees (pitch and roll) compared to traditional 4DoF (vertical, lateral, longitudinal, and yaw) when correcting for patient setup during image-guidance prior to treatment delivery. These tables allow for more accurate patient treatments and could poten…

Rapid detection and monitoring of visual field loss at home or in the clinic with simple instrumentation
TS-037934 — A kit that lay individuals or healthcare practitioners can use on a tablet or other mobile device to evaluate visual field loss using a rapid, self-administered test.
Individuals with diseases affecting the eye or brain are susceptible to losing parts of their visual field of view. The loss can be central (e.g. AMD), peripheral (e.g. glaucoma) or sectoral (e.g. stroke). Although there are therapy options to address such visual field loss, compromised vision can…

A Closed Loop System for Responsive Precise Intraparenchymal Delivery of Adenosine for the Treatment of Epilepsy
TS-037644 — Medical device for controlling seizures.
Adenosinergic neuromodulation plays a crucial role in control of seizure activity and is described as the brain's endogenous anticonvulsant. Intraparenchymal infusion of adenosine into epileptogenic regions of the brain has been shown to control seizures (anti-ictogenic) and prevent progressiv…

Nanopump Separation Device and Method
TS-037584 — A device for separating macromolecules in a solution of macromolecules having different molecular sizes
Many clinical and research applications involve separation of specific biological molecules, such as nucleic acids and proteins, for further analysis and characterization. A complex biological system can only be understood after each component has been separately analyzed, and proteins must be pur…
