Comparison of microtransducer and fiberoptic catheters for urodynamic studies.
OBJECTIVE To assess the validity and reproducibility of a fiberoptic transducer urodynamic catheter for urethral closure pressure profiles and leak point pressure determination, using a microtransducer catheter as the standard. METHODS Ninety women without significant pelvic organ prolapse underwent urodynamic evaluations with both fiberoptic and microtransducer catheters. Maximal urethral cl...
متن کاملAssessing respiratory function depends on mechanical characteristics of balloon catheters.
BACKGROUND Respiratory muscle function and lung and chest wall mechanics are reliably assessed by esophageal and gastric balloon catheters. The aim of this in vitro bench study was to assess the mechanical properties of commercially available balloon catheters using an experimental model with 3 defined compliances (27, 54, 90 mL/cm H2O). METHODS Six catheters were investigated in 4 conditions...
متن کاملDevelopment of a balloon volume sensor for pulsating balloon catheters.
Helium pulsed balloons are integral components of several cardiovascular devices, including intraaortic balloon pumps (IABP) and a novel intravenous respiratory support catheter. Effective use of these devices clinically requires full inflation and deflation of the balloon, and improper operating conditions that lead to balloon under-inflation can potentially reduce respiratory or cardiac suppo...
متن کاملManagement of obstructed balloon catheters.
Failure of a balloon catheter to deflate is not uncommon and prevents its removal. Methods of overcoming the problem include traction, bursting the balloon by overinflation, dissolving it with solvents, puncturing it percutaneously with a needle, or puncturing it with a wire stylet passed through the catheter. All except the last technique have major disadvantages and are of questionable safety...
متن کاملVisibility of Balloon Dilatation Catheters
In this study, an easy to use measurement method was developed to quantify the balloon dilatation catheters visibility, thus making them comparable. The visibility of the distal and proximal markers and the balloon (average values of the markers) was determined for fourteen balloons of the same type and material, but different lengths and diameters. Repeatability of these values was tested by o...
