Mesh deployment device used during laparoscopic procedures to prevent hernia

In response to the COVID-19 crisis, we are developing a mask that offers superior function in a fraction of the manufacturing time when compared to many emerging 3D printed mask designs. The design offers an improved seal around the face that is more comfortable, a more robust/airtight filter housing, autoclavable materials, and a quicker manufacturing method. This will allow local and national entities looking to produce DIY masks a better, faster alternative to 3D printing.

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.

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.

Brief Description: vasSecure aims to decrease carotid artery dissection rates during Transcarotid Artery Revascularization (TCAR) procedures by improving access and stability. The device allows surgeons to properly tension the artery while distributing the applied force, allowing surgeons to perform the minimally-invasive procedure effectively and reduce the risk of trauma to the artery.

Skin grafts are commonly used for wound closure and are cut with a mesh pattern to expand their coverage area. They are thin, delicate, painful to harvest, and easily damaged during traditional meshing. We observed need for a method to mesh skin grafts that is less prone to failure. Optigraft addresses this problem with technology that not only executes precise cuts without damage, but also measures the wound sites to allow for planning of optimal graft size and expansion ratio.

A major challenge presented by the COVID-19 crisis is the limited number of caregivers that can attend to the influx of patients requiring ventilators. Our alarm app and sensor system allows caregivers to monitor the real-time performance of conventional and novel ventilators for multiple patients at once. Such data could be used to compare trends in current patient outcomes with previously recorded ventilator data. This would allow clinicians to foresee complications and make more informed decisions in treating similar diseases.

The MRS is a specimen retrieval device that offers surgeons a way to remove malignant specimens during laparoscopic procedures without significantly widening minimally invasive incisions. The proposed device would use expandable braided sleeving to elongate and radially compress large tissue specimens for extraction through the initial incision. Use of this device would allow surgeons to remove large tissue samples through smaller incisions to reduce patient pain, recovery time, postoperative pain and length of hospital stay.

Ten-μ solutions plans to introduce time and cost savings to the operating room (OR) through application-specific single-use instrumentation. Our instrument will allow surgeons to position and tension vessel loops at their discretion.

For spinal surgeons who face difficulty visualizing the nerve root during spinal decompressions, the Meramec suction/elevator is a surgical instrument that combines multiple instrument functions to free surgeons' hands and increase OR efficiency. It combines the functionality and familiarity of existing suction tips and manual elevators with end effector geometry specific to the lumbar nerve roots, reducing the need to switch instruments. This improves OR workflow and increases patient safety.
