Filter by:To collect data on the routine patterns of use, safety and effectiveness, including the clinical and technical performance of the CorPath 200 System, in the delivery and manipulation of coronary guidewires and stent/balloon catheters during PCI procedures.
The primary objective of the Phase I ascending dose trial is to investigate the safety and tolerability of intramuscular (gastrocnemius) injections of human neural stem cell product, CTX, in patients with peripheral arterial disease (Fontaine Stage II through IV). This trial is based on independent preclinical data from a leading academic research institution that has been submitted for publication. Inclusion of patients with Fontaine Stage II is justified as these patients have a lower incidence of background events and will facilitate distinction between events which are possibly intervention-related versus spontaneous events associated with underlying advanced atherosclerosis. The trial is designed to treat 9-18 patients and evaluate safety measures over a 12 month follow-up period.
The purpose of this study is the evaluation and comparison of blood pressure variability indices and ambulatory arterial stiffness index obtained by ambulatory blood pressure monitoring as prognostic indicators in the functional outcome of acute ischemic stroke.
This study aims to investigate the predictive value of novel biomarkers and contrast-enhanced ultrasonography for early detection of abdominal end-organ (kidney and intestinum) hypoperfusion and ischemia in patients undergoing endovascular aortic repair (EVAR) for aortic aneurysm or dissection. In this context, patients will be monitored for renal biomarkers (TIMP-2, IGFBP7) and intestinal biomarkers (plasmatic intestinal fatty acid binding protein (i-FABP)) and local tissue perfusion will be assessed using contrast-enhanced ultrasonography (CEUS). The ultimate goal of this study is an early identification of patients developing one or both of these complications, which may facilitate a timely intervention to improve outcome.
This study will evaluate the safety and efficacy of intracoronary injection of mesenchymal stem cells (MSCs) to repair heart function in patients with myocardial ischemia.
One of the purpose of this study is to assess the preliminary safety and feasibility,and to provide related information and evidence for the design of the further pivotal randomized control trial.the other purpose is to assess the performace of the stent delivery system.
During the birth process certain conditions can cause oxygen delivery and/or blood flow to the baby's brain to become interrupted. This can cause permanent brain damage. Brain damage occurs in two phases. The first occurs at the time of injury when brain cells in the affected area 'die'. There is nothing that can be done about this. The second phase of injury occurs over the next few days. This second phase is caused by inflammation and release of toxic chemicals from the injured site. Cooling the baby to a temperature of 92.5° F, for 3 days has been shown to reduce the second phase of injury and bran death. All babies will receive the benefit of cooling. Although cooling helps it does not completely stop the second phase of injury. Melatonin is a naturally occurring hormone that is produced by the brain, and helps regulate the sleep-wake cycle. It has the potential to stop the second phase of brain injury by inhibiting inflammation and release of toxic chemicals. The reason for this research is to find out if melatonin can or cannot improve the outcome of babies with this kind of brain damage. Every baby enrolled in the study has a 50:50 chance of getting melatonin. A total of six doses of medicine will be given. The baby's brain function will be assessed by an EEG, brain oxygen monitoring, and a neurologic examination at 18 months of life. All of these are routinely used as part of standard care for patients with this kind of problem. The only difference is that half the babies enrolled in the study will get the drug called melatonin and the other half will receive placebo. The dose of melatonin being used in the study is higher than the amount normally produced by the body. No side-effects of this dose have been reported in other research studies using melatonin in newborn and premature babies.
The purpose of this study is to determine whether autologous bone marrow-derived stem cells are effective in the treatment of lower extremity ischemia.
The aim of the study is to analyze the present use of antithrombotic therapy on a large cohort of consecutive cardiacs undergoing non-cardiac surgery. If even and for how long the medication was discontinued, if any other antithrombotic therapy was used in the perioperative period and prevalence of perioperative complications - especially ischemic or bleeding. These complications will be correlated with the pattern of antithrombotic therapy administration. Working hypothesis is to obtain a large database of unselected cohort of consecutive patients for mapping of this practically important, but in the evidence-based medicine, still neglected problem.
