Ryan Klatte
Principal Research Engineer
(216) 445-0289
Ryan has over 11 years experience at the Cleveland Clinic’s Lerner Research Institute. He received his BS in Biomedical Engineering from the University of Akron. He worked with the Cardiovascular Assist and Replacement Lab for several years as a Research Engineer. His primary project was the development of the pulsatile MagScrew Total Artificial Heart blood pump and he was involved with the design and manufacture of blood-contacting components, vigorous in-vitro testing of the assembled TAH and over a dozen chronic in-vivo studies. Since joining the Medical Device Solutions (MDS) group, Ryan has been involved in dozens of early stage device prototypes, including biopsy needles, stents, staplers and a variety of catheter based cardiovascular devices. Currently, as Principal Research Engineer he is the engineering manager for MDS’ mechanical engineering team. His responsibilities include project management, mechanical engineering and design and CAD modeling for medical device prototypes, and research and development of new 3D Printing applications at the Cleveland Clinic.

Dave Dudzinski
Principal Research Engineer
Dave has over 12 years experience at the Cleveland Clinic’s Lerner Research Institute. He received his BS in Mechanical Engineering from the University of Akron. Dave has a very strong mechanical design background as well as hand-on machining experience. Dave worked with the Cardiovascular Assist and Replacement Lab within Biomedical Engineering from 1998 through 2009, progressing from Research Assistant through Senior Research Engineer. His projects were primarily related to the research and development of continuous flow rotodynamic blood pumps, including an inherently controlled bearing centrifugal pump, LVAD and RVAD versions of an axial blood pump and specifically the PediPump (a VAD developed for use in pediatrics). He also worked on enabling technologies, including a PID blood pump controller, a Ferro-fluid pump dynamometer, an axial magnetic bearing dynamometer, and an air-motor to drive a blood pump, as well as numerous other smaller projects. Dave joined the Medical Device Solutions group in 2009 and has been involved in a variety of projects. He assisted the Prototype Laboratory for a number of months and gained invaluable experience in lathe and mill operation. Projects he has worked on include the mechanical and hydraulic design of a prosthetic knee as well as mechanical design of catheter based vascular device prototypes. In his current position as Principal Research Engineer, Dave has operational oversight of the newly acquired Femto-laser cutting system, which MDS is using for fabricating complex devices in Nitinol, other metals and even polymers.

Mark Lobosky
Senior Principal Research Engineer
Mark Lobosky has over 25 years engineering experience related to manufacturing and management. He received his BSME form Cleveland State University. Past employers include Ranpak Corporation, Perfection Corporation and Paramount Metal Products. Mark has a particularly strong background in welding procedures as well as machine design, including mechanics, pneumatics, hydraulics, electrical controls, PLC’s and robotics. At Ranpak Corporation he was employed as Engineering/Quality Manager responsible for equipment and paper dunnage and he worked closely with European sister division, North American paper suppliers, and Asian equipment suppliers involving design and application issues. At Perfection Corporation, Mark started as a Welding Engineer progressing to Plant Engineer, Machine Development Engineer, and Engineering Manager. His accomplishments there include developing a complete welding department to A.S.M.E SECTION IX standards including equipment and welding procedures for pipe, tubing, machined and structural components as required for product lines. He also developed polyethylene fusion department to industry standards for ½” CTS thru 12” IPS product lines including greasing, assembly, fusion, and leak testing equipment. Their products included: risers, tees, Y’s, elbows, straight stick, couplings, plug and ball valves. At Paramount Metal Products, Mark was employed as Welding Engineer responsible for welding program utilizing G.M.A.W. and R.S.W. processes. Other responsibilities included prototypes, product development, material testing, tooling design, and customer support. Mark arrived at MDS in early 2011 and he is heavily involved in design and development of prototype medical devices. His strong machine design background and expert knowledge of Geometric Dimensioning and Tolerancing are being put to good use!

Matt Streicher
Research Engineer
Matt received his BS in Biology from Denison University followed by his MS in Biomedical Engineering with a focus on Sports Biomechanics from the University of Akron. He has over 3 years of experience at the Cleveland Clinic’s Lerner Research Institute. Prior to his current position within MDS, Matt completed an internship at the American Sports Medicine Institute in Birmingham, Alabama. Matt has a strong background in biomechanics and gait analysis research. While at the American Sports Medicine Institute, Matt completed his Master’s thesis research using motion analysis technology to study the biomechanics of the baseball pitching motion. His thesis, “Kinematic comparison of marker set techniques used in biomechanical analysis of the pitching motion” looked at two different motion capture marker sets that are used to quantify the biomechanics of baseball pitching. In addition to collecting his thesis data, Matt assisted in several other biomechanics research projects taking place at ASMI. Since joining Medical Device Solutions, Matt has been heavily involved in a research study evaluating patients with Normal Pressure Hydrocephalus using biomechanical techniques. These techniques include postural stability assessment using force plate and head accelerometer technology, treadmill walking with force plate assessment, as well as gait analysis. In addition to the NPH Study, Matt has performed gait analysis procedures for several different populations including patients with multiple sclerosis, cerebral palsy, amputees, and patients using rehabilitation assisting devices. He is familiar with multiple variations of human subjects protocols involving the IRB. With the recently awarded CARE grant received by the Cleveland Clinic, Matt will become one of the lead operators of the new virtual reality treadmill system coming in the near future.

Sergey Samorezov
Senior Principal Research Engineer
Sergey Samorezov has over 29 years of experience in mechanical engineering. He has MSME degree from Nikolaev Maritime University in the former Soviet Union, and also is an ISO Certified Vibration Specialist. His areas of expertise include prototype development, system troubleshooting, creative problem solving, vibration and acoustics.
