Fabrication of Shape Memory Polymer Nanocomposite Foams with Surface Modified Nanoparticle Fillers Emery, Harrison (2015-09-24)Every year, 30,000 individuals in the United States will suffer from a ruptured cerebral aneurysm. The Biomedical Device Laboratory seeks to improve on current aneurysm treatment by using a low-density, high-volume shape ...
-
Grant, Katharyn Anne-Marie (2018-04-19)Polyurethane shape memory polymer (SMP) foams are ultra-low density, “smart” materials that transition between a primary and secondary shape when exposed to a thermal stimulus. This material has the potential to be used ...

Darrouzet, Stephen 1987- (2011-04-21)In the area of translational research, stent developers consult pathologists to obtain the best and most complete amount of data from implanted test devices in the most efficient manner. Through the use of micron-scale ...
-
Frederick, Jane (2015-09-24)A new device based on porous, stimulus-responsive materials is being developed for the treatment of brain aneurysms. Shape memory polymer (SMP) foams can be heated above their transition temperature (Ttrans) and crimped ...
-
Nash, Landon 1990- (2012-04-23)In this work, shape memory polymer neurovascular stent prototypes based on a previously proposed design were thermo-mechanically characterized to expand on the clinical efficacy of the device. The stents were made by ...

Biswas, Saurabh (2011-01-21)Congestive heart failure (CHF) is a major public health issue in the developed and developing world. In the U.S., CHF affects more than 5.3 million people with 550,000 new cases diagnosed each year. Approximately 20 percent ...
-
Pfau, Michaela R (2021-05-04)The use of self-fitting scaffolds based on thermoresponsive shape memory polymers (SMPs) offers a potential solution to treat craniomaxillofacial (CMF) bone defects via regenerative healing. Porous SMP scaffolds were ...
-
Muschenborn, Andrea Denise (2013-09-26)Stroke is a cardiovascular disease that results in the abnormal blood supply to the brain either by the lack thereof (i.e., ischemia), or hemorrhage, both causing a rapidly developing loss of brain function. It affects ...
-
Shape Memory Polymer Systems with Advanced Processing Capabilities and Tunable Mechanical Properties Hearon, Michael Keith (2014-11-26)The ability of shape memory polymers (SMPs) to undergo geometric transformations upon exposure to stimuli has inspired application-driven research in a diverse array of scientific fields. The shape memory effect has been ...
-
Balakrishna, Kedar H (2017-04-28)Shape memory polymers (SMPs) are proposed for use in a variety of medical devices, such as neural and peripheral embolism coils for aneurysm occlusion. These “smart” materials have unique advantages over shape memory alloys, ...
-
Kristufek, Samantha Lynn (2017-05-05)We have a keen interest in the design, preparation and investigation of engineering polymers that are derived from renewable biofeedstock resources. Natural products allow for access to diverse structures and provide a ...
-
Ezell, Kendal PShape memory polymer (SMP) foams have been proposed for a variety of medical applications, including brain aneurysm embolization and occlusion of peripheral vascular malformations. While these devices provide significant ...
-
Easley, Alexandra Danielle (2015-09-24)Vascular aneurysms are a significant source of morbidity and mortality, affecting 3 to 5 million Americans annually. Current treatments often require either highly invasive strategies to surgically occlude the aneurysm or ...
