DESCRIPTION (provided by applicant): The objective of this proposal is to develop a less invasive long-term copulsation device to treat patients in late Class III and early Class IV stages of heart failure (HF). Chronic congestive heart failure is the largest unsolved problem in cardiac care today. There are over 5.5 million people in the United States with this diagnosis and the number of patient ...

DESCRIPTION (provided by applicant): The objective of this SBIR program is the modification of a polymeric trileaflet heart valve to a valve prosthesis that can be delivered percutaneously as a transcatheter aortic valve replacement. Key innovations include improved durability and hemodynamic properties, lower manufacturing costs, and simplified delivery over existing transcatheter bioprosthetic v ...

DESCRIPTION (provided by applicant): The overall objective of this proposed program is the commercialization of the Pediatric Impella system, a minimally invasive ventricular assist device (VAD) for treatment of acute heart failure in pediatric patients. The device will be a less traumatic alternative to extracorporeal membrane oxygenation (ECMO), the current standard of care for these patients. T ...

This SBIR project aims at the development of an innovative technology that can be attached to existing submerged arc welding (SAW) systems to monitor and feedback control the depth of weld penetration. Existing SAW systems will be operated using existing welding procedures without modifications. In many applications skilled welders may adjust the welding parameters based on their observation of dy ...

The aluminum alloys have low density, relatively high strength, and high strength-to-weight ratio, which brings some major advantages in marine structure design, fabrication, and operations. However, marine ships are subjected to a complex and severe loading, and the typical failure mode of aluminum under extreme dynamics loading such as wave slamming and high velocity impact is ductile fracture. ...

Research is proposed for the development and implementation of state of the art computational and experimental tools for the investigation of the impact of control surface freeplay on the flutter and limit cycle oscillation characteristics of two-dimensional and three-dimensional wings in subsonic and transonic flow. Highly efficient and accurate aeroelastic simulation tools will be constructed ba ...

This Small Business Technology Transfer Phase I project is aiming at developing and implementing a multiscale composite model to predict the ceramic matrix composite (CMC) response to the impact loading by foreign objects. In particular, the physics-based model will be applied to describe the multiscale foreign object damage (FOD) phenomena of CMCs due to the complex nature of impact dynamics coup ...

Turbine disks are amongst the most critical components in aero- and naval-vessel engines. They operate in a high pressure and temperature environment requiring demanding properties. Nickel-based supperalloys which have high creep and oxidation resistance at high temperatures are widely used as the material of turbine disks. The elevated-temperature strength of this supperalloy and its resistance t ...

Research is proposed for the development and implementation of state of the art, reduced order models for problems in nonlinear aeroelasticity. Highly efficient and accurate aeroelastic simulation tools will be constructed based upon the mathematical formalism of optimal prediction theory and a novel implementation of a filtered harmonic balance solution methodology. The implications of the propos ...

According to existing data, there are more than 1.5 million of Americans sustaining a Traumatic Brain Injury (TBI) each Year. Balance disorders represent one of the main regular problems that patients have to deal with, and thus everyday. Rehabilitation programs do exist but they are dependable of the clinician or physiotherapist and they do not take in account the multimodal aspects of balance co ...
