摘要： Medical devices for removing gasses, such as gas bubbles and/or dissolved gasses, from a liquid to be delivered to a patient, and methods of use and making of such devices. In at least some embodiments, a gas permeable membrane material is used in the construction of the gas removal devices. In some embodiments, layers of gas permeable membrane material are used to construct a filter structure for removing gas from the liquid. In other embodiments, hollow tubes and/or fibers of the gas permeable membrane material are used to construct a filter structure for removing gas from the liquid. The gas removal devices may be used in any of a broad variety of liquid delivery systems and/or configurations.

摘要： An improved and simplified catheter construction is provided to enhance the steerability of the catheter. The catheter(s) includes an elongate flexible relatively torsionally rigid core wire attached securely at each of the proximal and distal ends of the catheter. The core wire adds sufficient torsional rigidity to the catheter to enhance the steerability of the catheter when the catheter is manipulated from its proximal end by the physician. The catheter avoids the need for incorporating helically braided tubes in the wall of the catheter. The invention may be used to make a catheter having a reduced outer diameter or an increased inner luminal diameter.
