Slocum, and Nikolay V. Vasilyev<br/> Direct-access, minimally invasive, beating-heart intracardial procedures have the potential to replace many traditional surgical procedures requiring cardio-pulmonary bypass as long as micro-emboli are prevented from entering the cardiovascular system. A new surgical port was developed to introduce ... [J. Med.

Nelson<br/> For this study, we have collected puncture force data from the vasculature of the chorioallantoic membranes (CAM) of developing chicken embryos to examine forces required for retinal vein cannulation. The CAM vessels of a developing chicken embryo have been shown to be an appropriate model for human ... [J. Med.

Kim<br/> Tissue micro array (TMA) is based on the idea of applying miniaturization and a high throughput approach to hybridization-based analyses of tissues. It facilitates biomedical research on a large scale in a single experiment; thus representing one of the most commonly used technologies in translation ... [J. Med.

Litten, JungHun Choi, and David Drozek<br/> Colonoscopy can be associated with many problems, such as mechanical trauma due to the distal tip contacting the colon wall or health issues due to the extended use of anesthesia. In order to eliminate these complications, an automatic adjustable colonoscope was designed. This device uses sensors, a ... [J. Med.

Cuadrado<br/> Plates and non-locked screws used in the treatment of osteoporotic bone fractures frequently become loose due to everyday mechanical demands. Currently, locking plates and screws are the gold standard treatment for these fractures. However, their use has several limitations and complications as they ... [J. Med.

Miller, Theresa W. Fossum, David A. Nelson, and John C. Criscione<br/> One of the major maladaptive changes after a major heart attack or cardiac event is an initial decline in pumping capacity of the heart leading to activation of a variety of compensatory mechanisms, and subsequently a phenomenon known as cardiac or left ventricular remodeling, i.e., a geometrical ch ...

Miller, Theresa W. Fossum, David A. Nelson, and John C. Criscione<br/> One of the maladaptive changes following a heart attack is an initial decline in pumping capacity, which leads to activation of compensatory mechanisms, and subsequently, a phenomenon known as cardiac or left ventricular remodeling. Evidence suggests that mechanical cues are critical in the progress ... [J. Med.

Although bioreactors are conceptually relatively simple, the vast majority of current bioreactors (commercial and custom-built) are not fully adapted t ... [J. Med.

Taylor<br/> Computer modeling of blood flow in patient-specific anatomies can be a powerful tool for evaluating the design of implantable medical devices. We assessed three different endograft designs, which are implantable devices commonly used to treat patients with abdominal aortic aneurysms (AAAs). Once imp ... [J. Med.

Richardson, George R. Dodge, and Tariq Rahman<br/> Distraction osteogenesis is a routine surgical procedure to lengthen a long bone. A fixed lengthening rate is typically used. We investigate measuring forces continuously and producing a variable distraction rate. A motorized distractor was instrumented with a load cell to measure the forces develop ... [J. Med.
