Within cranial bone defect treatments, autografts remain the current gold standard for best healing outcomes. However, if the defect is of a unique shape, this process proves difficult and often requires additional surgeries. ...
-
(2014-05-01)The shape memory polymer (SMP) is one type of smart material with shape memory effect. SMP’s recovery can be actuated by external energy, such as heat. However, traditional direct heating limits potential applications of ...
-
(2014-05-09)Cerebral aneurysms are unstable localized dilations of an artery wall located in the vasculature of the brain that are susceptible to rupture. Current treatments of aneurysms, both surgical and endovascular, involve isolation ...
-
(2019-04-26)Cranio-maxillofacial (CMF) bone defects are most commonly treated with autografts despite their many limitations. Namely, the rigid autografts are difficult to shape and fit into complex defect geometries, resulting in ...
-
(2013-09-27)Due to its complex phase transformation behavior, a Shape Memory Polymer filled honeycomb composite has been proposed as an efficient material for skin on a morphing wing. This work develops a finite element model of the ...
-
(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 ...
-
(2016-05-02)Endovascular therapy involves the placement of an implantable filler coil directly into an aneurysm sac to occlude the space and promote healing of the damaged vessel wall. Implantable devices must be tested to assess and ...
-
(2022-10-18)Our laboratory has developed oxidatively degradable shape memory polymer (SMP), polyurethane foam vascular occlusion devices: a peripheral embolization device (PED) that employs a large-pore foam plug and neurovascular ...

Shape Memory Polymer Systems with Advanced Processing Capabilities and Tunable Mechanical Properties (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 ...
-
(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 ...
-
(2009-05-15)The aim of this work is to demonstrate a Helmholtz potential based approach for the development of the constitutive equations for a shape memory polymer undergoing a thermomechanical cycle. The approach is motivated by the ...
