2009 Capstone teams


Project & Title:  Anesthesia & Perioperative Care: Multi-animal Anesthesia Delivery With Conserved Stereotaxic Accuracy

Team Members:  Edward Ha, Iris Jiang, Kim Nguyen

Capstone Client:  Jennifer Shih, Stratman Lab, UCSF

Over 30 million people in the U.S. per year undergo general anesthesia for medical procedures. Research has shown that long exposure times to anesthesia may have detrimental effects on the brain. The Capstone team introduced a modular design that integrates the aspects of large-scale anesthesia delivery with stereotaxic accuracy.

Cochlear Implant

Project & Title:  Hearing Deficits: Improved Deep Brain Probe Fixturing Compatible with Current Probes

Team Members:  Brian Pham, Vinh Ho, Jason Gomez

Capstone Client:  Ben Bonham, PhD, Associate Adjunct Professor, Otolaryngology, UCSF

According to the FDA 188,000 people around the world received cochlear implants (April, 2009). The benefit of cochlear implant is to help cure deafness. The team developed a system/device that will allow precise insertion of chronic probes into the central nucleus of the inferior colliculus (CNIC).

Emergency Medicine

Project & Title:  Disposable Manometer

Team Members:  Tina Chan, Tiara Franklin, Roger Lowe

Capstone Client:  James Hardy, M.D., UCSF, Emergency Medicine Specialist

Electronic manometers offer an accurate and easy-to-read measurement. However, the transducer makes contact with patient blood so it must be disposed of after every patient. The team set out to develop a device to measure central venous pressure for sepsis situations in developed healthcare systems. The device will function in real time and demonstrate reproducibility. The device will also be more maneuverable and less expensive.

Neurological Surgery

Project & Title:  Stem Cell Delivery to the Brain
Team Members:  Janna Serbo, Michelle Tsai, Oliver Tilk, Brandon Miller
Capstone Client:  Daniel Lim, M.D., PhD., Department of Neurological Surgery, UCSF
The team designed a stem cell delivery device that is target specific and does not damage brain tissue. The device should deliver live cells with 1-3 penetrations to 2-7 square centimeters of the putamen, a portion of the brain treated for Parkinson’s disease.

The L Hose has a retractable interior tube that ejects cells to a large radial area and depth.

Pediatric Immunology

Project & Title:  Pain Minimization of Child Vaccination Procedure

Team Members:  Cynthia Chuang, David Fanjung, Victor Olivas, Nina Revko

Capstone Client:  Wilbur Lam, MD, PhD, Pediatric Hematology-Oncology, UCSF

Currently there are over 100 million immunizations administered annually. The vaccination process may leave the child in a lot of pain resulting in a tremendous amount of anxiety for the parent. The team designed a system which allows for simultaneous injection, in hopes to minimize the pain experienced during intramuscular vaccinations by patients.

Pediatric Medicine

Project & Title:  Innovations in Congenital Diaphragmatic Hernia (CDH) Treatment

Team Members:  Traci Fitzharris, Scott Grubb, Monica Sevilla

Capstone Client:  Doug Miniati, MD, Pediatric Surgeon, UCSF

Congenital Diaphragmatic Hernia (CDH) leads to lung hypoplasia, abdominal organs migrate into chest and press upon developing lungs. This occurs once in every 2500 births. The team set out to create a device which allows for the oscillation of stretching and latent growth pressure stages in fetal lungs. (i.e. “fetal breathing”).



Project & Title:  Minimally Invasive Blood Draw System for Use in Neonates

Team Members:  Jeff Kang, Angela Ren, Mia Shanholtzer

Capstone Client:  Wilbur Lam, MD, PhD, Pediatric Hematology-Oncology, UCSF

Obtaining blood samples for laboratory testing is a commonplace medical practice, which can be extremely difficult in some patients (e.g. infants, the elderly & chronically ill). Pre-term infants often subjected to up to 20 painful procedures/day. The team designed a novel neonatal blood draw system that is minimally invasive, capable of drawing several milliliters of blood, and confers no adverse effects upon blood sample integrity.
