Growth-Accomodating Transcatheter Pulmonary Valve System

UCI researchers have developed a novel transcatheter pulmonary valve (TPV) that addresses the current lack of options for children with progressive pulmonary valve regurgitation (PVR), which may lead to right ventricular (RV) dysfunction and failure. This TPV allows for implantation into patients of a younger age, preventing the progression of PVR and the RV issues that follow, and can also expand to accommodate the need for a larger pulmonary valve as the patient grows.

Simple, User-friendly Irrigator Device for Cleaning the Upper Aerodigestive Tract and Neighboring Areas

Researchers at UCI have developed a user-friendly consumer medical device capable of cleaning and removing food particles and bacteria that accumulate in and around the back of the throat. Without removal, this accumulation may lead development of halitosis (bad breath) or inflammation that may require more serious medical intervention.

(SD2021-087) Bioinspired Wet Adhesives: Suction discs for adhesion to rough, delicate, and wet surfaces

Adhesion involves highly complex and hierarchical structures in nature, and by understanding the biological intricacies of such adhesive structures, one can improve engineered adhesives. The role of reversible adhesion in both the natural world and in engineering is to temporarily bind to a surface, providing the opportunity to detach and re-attach as needed. In nature, animals use attachment to enhance their fitness.  In robotics, reversible adhesion enables improved manipulation and locomotion by managing contact at the interface between the robot and its environment.

Staged Fascial Closure Device

The current invention enables the safe closure of an open abdomen during surgery when the abdominal fascia cannot be closed primarily.

Researchers from the University of California, Irvine have developed a new method and device to efficiently mix and analyze liquid samples on CD-based point of care devices.

2-D Polymer-Based Device for Serial X-Ray Crystallography

Researchers at the University of California, Davis have developed a single-use chip for the identification of protein crystals using X-ray based instruments.

Integrated Virtual Reality and Audiovisual Display Support System for Patients in a Prone Position

Researchers at the University of California, Davis have developed an integrated virtual reality and audiovisual support system that increases the comfort of patients who are undergoing diagnostic tests or medical procedures in the prone and other positions.

Digital Droplet Infusion System for High-Precision, Low-Volume, Delivery of Drugs or Nutritional Supplements

Researchers at the University of California, Davis have developed the first, digital, droplet infusion system capable of high-precision delivery of very low-volume therapeutics or nutraceuticals.

Device for Spinal Dural Repair

Dural tear is a frequent and costly complication of spinal surgery, which can cause cerebrospinal fluid (CSF) leakage, triggering additional, serious post-operative difficulties. Researchers at UC Irvine have developed a new method and device to mitigate dural tears in a rapid, safe, and water-tight manner

Seamless Ceramics for Biomedical Applications

Prof. Guillermo Aguilar-Mendoza and his colleagues from the University of California, Riverside (UCR) and Prof. Javier Garay and his colleagues from the University of California, San Diego have developed an all ceramic, biocompatible, hermetically sealed package for encapsulating electronics. This technology uses disparate transparent polycrystalline ceramics and is sealed by laser.  The laser directly joins the disparate surfaces, protecting the electronic device from damage while ensuring a high-quality seal. This state-of-the-art technology provides  superior packaging for biomedical implant devices that has long-term biocompatibility. It also provides safe and leak-proof seals.

Percutaneous Heart Valve Delivery System Enabling Implanted Prosthetic Valve Fracture

UCI researchers developed a percutaneous heart valve delivery system to deliver and implant a prosthetic valve. This system incorporates the means to fracture a previously implanted prosthetic valve in situ without interfering with the transcatheter valve to be implanted.

Novel Tunable Hydrogel for Biomedical Applications

Prof. Huinan Liu’s lab at the University of California, Riverside has developed a novel tunable hydrogel that achieves tunable crosslinking, reversible phase transition, and may be used as a 3DP scaffold. This new hydrogel utilizes dynamic coordination of its innate carboxylic groups and metal ions. Adding methylacrylate or other functional groups is not required for this technology and the resulting hydrogel is less toxic. Since the functionalization of this hydrogel is not required, it is less process-intensive and results in a more cost-effective hydrogel.  In addition, the UV curing is no longer needed since methylacrylate is no longer utilized to crosslink the hydrogel.   Fig 1: Optical micrographs of top view and cross-section of HyA hydrogels printed using cold-stage method and direct writing method. Hydrogels printed using direct writing method showed better structural integrity and stability.

Hemoglobin Carrying PEG Microspheres As Artificial Red Blood Cells

Researchers at the University of California, Irvine have developed artificial red blood cells consisting of hemoglobin that is tethered to polyethylene glycol (PEG) molecules and formed into microspheres.

New positron emission tomography (PET) imaging agent developed that uniquely binds to synucleinopathies and tauopathies in the Parkinson’s brain and may therefore serve as an early diagnostic marker.

Photoacoustic Spectroscopy Detection Of HFA, NO, And C02 From Exhaled Breath

UCI researchers introduced a medical device which simultaneously detects hydrofluoroalkane (HFA), carbon dioxide (CO2), and nitrogen monoxide (NO) in exhaled breath for monitoring and improving treatment of asthma and chronic obstructive pulmonary disease (COPD).

High Efficiency Single Cell Indexing Of Droplets Via Interfacial Shearing With Downstream Droplet Sorting

The invention is an integrated device that provides a high efficiency single cell encapsulation solution. The two core modules of the invention are responsible for generating the cell encapsulating droplet, then sorting the generated droplets to eliminate the empty ones. Such a two-step process yields a high throughput, single cell indexed droplets, with an overall encapsulation efficiency reaching 80%, which is crucial for various applications ranging from genomics and proteomics to pharmacology.

Delivery System For Transcatheter Valves

Researchers at UCI have developed a novel medical device for use in transcatheter heart valve replacement surgeries. The device provides physicians with more careful control of the catheter insertion, minimizing complications and adverse effects.

Esophageal Deflection Device

Cardiac ablations are common medical treatments for people with atrial fibrillation (Afib). During the ablation procedure, a cardiac electrophysiologist will thermally ablate, or burn off, defective heart tissue with radiofrequency or cryoablation technology. The esophagus is often in close proximity to the left atrium. Since the left atrial tissue is approximately 2mm thin, the heat can transfer through it to the esophagus in contact and cause thermal damage / lesions on the esophagus.  In worst-case rare scenarios, an atrio-esophageal fistula, or hole between the esophagus and the heart, can occur which has a ~75% mortality rate.  It would be ideal to move the esophagus away from the heart before or during the ablation procedure preventing thermal damage.

Particle-Sorting Device for Isolation, and Enrichment of Particles at Ultra-Low Concentrations

The ability to detect and sort particles by type is important to many fields, such as medical diagnostics, environmental monitoring, and food safety.UCI researchers have developed a platform to sort and isolate particles from a turbid medium with minimal pre-processing. The platform is very desirable for applications in which enrichment of particles or biological substances at low concentrations is necessary.
