Herting, Scott Michael (2020-11-19)Embolic coils have become a valuable tool for occluding brain aneurysms to reduce the occurrence of hemorrhagic strokes and the associated high mortality and morbidity rates, but this strategy is still limited by high rates ...
-
Zaballa, Vincent (2013-09-28)Polyurethane shape memory polymer (SMP) foams have been shown to be biocompatible within porcine models and show potential to treat intracranial saccular aneurysms in patients, and use in other medical applications. After ...
-
Rivera, Nicole C (2015-04-15)Reticulation, the process of opening and removing cell membranes from shape memory polymer (SMP) foam, is an important processing technique to improve the permeability of SMP foam for utilization in several biomedical ...
-
Weems, Andrew Christopher (2017-05-31)Shape memory polymer (SMP) polyurethanes have been proposed for a variety of vascular devices due to their biocompatibility, stimuli-responsiveness, and tunable properties. While this technology shows promise, a primary ...
-
Eagleston, Scott 1990- (2012-04-20)SMP foams have unique properties that make them well suited for certain medical applications. SMP foam has the ability to be programmed to “remember” a temporary shape, and once heated can revert back to its original ...
-
Horn, John David (2018-04-30)To mitigate the risk of intracranial aneurysm rupture, which can lead to severe debilitation or death, embolic devices (e.g., bare metal coils or polymeric open-celled foams) are often delivered via catheter to the aneurysm ...
-
Boyle, Anthony John (2016-12-13)Standard endovascular treatment of intracranial saccular aneurysms has been shown to be an effective treatment method, but it remains marked by aneurysm recanalization despite continued development of new device technologies. ...
-
Mims, John (2009-07-27)The American Heart Association estimates that congestive heart failure (CHF) affects over 5 million people in the United States. Recent research indicates that current pharmacological therapies have limitations in their ...
-
Rispoli, Joseph V (2015-06-05)The growing availability of high-field magnetic resonance (MR) scanners has reignited interest in the in vivo investigation of metabolics in the body. In particular, multinuclear MR spectroscopy (MRS) data reveal physiological ...
-
Landsman, Todd Lawrence (2016-08-03)Polyurethane shape memory polymers (SMPs) have found a variety of uses in the medical industry in the form of self-tightening sutures, suture anchors, ligament fixation devices, vascular stents, and thrombectomy devices. ...
-
Hwang, Won Jun (2014-09-05)Shape memory polymers (SMPs) are a unique class of smart materials that can remember two shapes, and can be remotely actuated to achieve a predefined shape by application of thermal energy. Porous scaffold of SMP foams ...
-
Wierzbicki, Mark Allen (2017-05-09)Patent ductus arteriosus (PDA) is a congenital cardiovascular defect in which a fetal connection between the aorta and pulmonary artery does not close spontaneously shortly after birth. This defect is the most common ...
-
Orendain, Adam M (2017-09-20)Endovascular embolization is an interventional procedure to seal off diseased vasculature from systemic circulation. Shape memory polymer (SMP) foams are a promising embolic material that can undergo shape change when ...
-
Szafron, Jason Michael (2013-09-28)Stroke is a leading cause of death and debilitation in the United States, with ischemic stroke in particular affecting hundreds of thousands of people every year. Treatment options for ischemic stroke have several limitations. ...
-
Shelton, Ryan 1983- (2012-08-15)Cellular/subcellular imaging of biological tissue is an important tool for understanding disease mechanisms. Many current techniques for subcellular absorption contrast imaging, such as two-photon excited fluorescence ...
-
Loftin, MadelinePatent ductus arteriosu is a condition wherein is a condition wherein the ductus arteriosus, or the natural port between the aorta and pulmonary artery during canine fetal development, fails to spontaneously close shortly ...
-
Muschalek, Rachael Lee (2017-04-26)Shape memory polymer (SMP) foams have been developed for various embolic applications. These polyurethane materials can be deformed and stored in a secondary shape, from which they can recover their primary shape after ...
-
Eight-Channel Head Array and Control System for Parallel Transmit/Receive Magnetic Resonance Imaging Moody, Katherine (2014-08-11)Interest in magnetic resonance imaging (MRI) at high fields strengths (3 Tesla and above) is driven by the associated improvements in signal-to-noise ratio and spectral resolution. In practice, however, technical challenges ...
