The URMC Kidney Model Optimization Project aims to create a polymer material that can simulate the human kidney for practice by surgical residents. Bimpe Isafiade, Harshita Mahaseth, Natalie Ramesh, Baris Eser Ugur

The aim of this project was to design a device capable of removing impacted food boluses in pediatric patients both more efficiently and more quickly compared to current industry standards.

A surgical drain is placed within an internal wound site to prevent fluid from accumulating in the body throughout the patient’s recovery. A suture is currently used to secure the drain to the patient but has multiple shortcomings including infection risk and failure over time. We have worked alongside Dr. Sara Neimanis to create a new securement device that minimizes infection while durably securing the drain over extended periods of time.

The cautery phantom senior design team will engineer and improve a system that will arrest artificial blood flow in response to electrocautery in a tissue phantom manufactured by Simulated Inanimate Models, LLC (SIM). To solve this problem, we have investigated methods of vessel constriction by lining the tissue phantom blood vessel wall with a thermoresponsive material, coagulating the artificial blood by introducing proteins and chemicals into the mixture, and by making the blood vessel with a shape memory polymer.

Development of polymers to simulate kidney tissues for surgical training of medical students at UR Medical Center.

Cataracts, a hardness and opacifying of the lens, is the leading cause of curable blindness worldwide, with the majority of cases occurring in developing countries where trained ophthalmologists are scarce. Our project is to develop a device to be used for a simplified cataract surgery that will insert a cylindrical intraocular lens into the cataract. By simplifying the procedure, more healthcare providers can be trained to perform the procedure, increasing the accessibility of cataract treatment in developing countries.

We were given a patient reported symptoms dataset PRO-CTCAE and applied a variety of clustering methods. The clusters were then statistically tested for associations with a selection of outcomes such as hospitalization. We found significant associations with clusters and outcomes and compared it to linear regression results.

Tibial shaft fractures are a common injury and may require surgical intervention. During our team's observation of trauma surgeries at Strong Memorial Hospital, we found the procedure was inefficient. Tools used to align bone may move, and people holding alignment are prone to fatigue. Each time a tool moves, alignment is checked or redone using X-ray. Our device clamps to the surgical bed and locks the position of instruments reducing staff needed to hold alignment and increasing efficiency.

To create a device that is minimally invasive that will be used to measure a patient's blood composition (hematocrit and blood plasma) using electrochemical impedance spectroscopy to track changes in blood volume.

Various post-operative complications may lead cardiac surgeons to opt for delayed sternal closure following open heart surgeries. Patients’ sterna are left open and they are cared for in the intensive care unit for 1-7 days. In the ICU, bedridden patients are turned to prevent pressure ulcers and for linen changes. During these turns, the sternal halves rotate and twist, potentially leading to injury or death. Our device stabilizes the sternal halves during transport and turning, greatly increasing patient safety.

Our project focuses on solving the need to decrease the amount of muscle obstruction during minimally invasive lumbar surgeries in order to increase the surgeon’s visualization of the surgical field. We developed a medical device that decreases the muscle obstruction by expanding an inflatable at the base of a cylindrical port. The product was tested in a PVA mixture that resembles similar material characteristics as muscle which proved the plausibility and efficacy of the concept.

After a total knee arthroplasty (TKA) surgery, some patients experience infection at the surgical site. This infection is often associated with the formation of bacterial biofilm, and in order to treat this, the surgeon must remove and replace the implant with the risk of reduced mobility and bone fraction. Our project is to develop a medical device to eradicate the biofilm without the necessity to remove the orthopedic implant.
