TEAM
Neil Roundy, MD (Co-Founder and Chief Medical Officer) is a
neurosurgeon with Oregon Neurosurgery Specialists, a private practice
group in Eugene, OR. His work interests include skullbase surgery,
minimally-invasive intracranial & spinal surgery and neuroendoscopy.
Rachel Dreilinger (Co-Founder & CEO) is a biomedical engineering
consultant specializing in the design of medical devices with experience
in orthopedics, neurosurgery, dentistry, resorbable polymers, mechanical
design and all phases of product development.
Eric Hanson, MD, MPH (DoD Biomedical Consultant) is a former
US Air Force Senior Flight Surgeon and Division Chief of Science &
Technology. He has received $68M in funding as a lead PI in DoD
research programs and set up over $1.5M in cooperative R&D
agreement (CRADA) value in the last two years for NW biomedical
companies.
THE BIG IDEA
Bioabsorbable Clip for Durotomy Closure
▪ Watertight closure
▪ No imaging artifact
▪ Multiple clips applied
quickly
▪ Low-profile applicator
▪ Reduced OR time
CLINICAL NEED - The Problem
▪ High incidence of durotomy closure
(~170k cases/year in the U.S. in 2010)
▪ Limited surgical site exposure
▪ Long, narrow working channels
▪ Prevalence of Minimally Invasive Surgical
(MIS) techniques
▪ Current suture technique can take up to
60 minutes or more
▪ Operative time is very expensive ($29-
$133/minute)
▪ 30 min case x $80/min = $2400!
VALUE PROPOSITION & UNIQUENESS
▪ Vast improvement over current methods of
watertight closure (running suture)
▪ NO OTHER bioabsorbable clips available for
closing the dura
▪ Other surgical closure devices:
1. Metallic/Penetrating (U-Clip by Medtronic)
2. Metallic/Crimping/Non-Penetrating (AnastoClip
by Le Maitre Vascular, Duraclose by Stryker)
3. Bioabsorbable/Penetrating (Vicryl Suture by
Ethicon)
Designs and Prototypes
MARKET ANALYSIS (Spine Surgery ONLY)
 Durotomy closure cases: $80/min x 30 min = $2400
 2010: 1.7M spinal surgeries in U.S.
 ~10% require durotomy closure = 170k cases/year
 $170k x $2400/procedure = $408M
INDICATION EXPANSION
 Colectomy (Ulcerative Colitis): average 19,970/year
(2008-2010) x $2400/case = $48M
 Ostomy Procedures: 120k/year x $2400 = $288M
 Cranial Neurosurgery: 250,000 craniotomies performed
yearly in the U.S. 250k x $2400/case = $600M
 Tubal Ligation: 700k procedures/year x $1,000/device =
$700M
 $2B POTENTIAL MARKET
