摘要： An access port for subcutaneous implantation is disclosed. Such an access port may comprise a body for capturing a septum for repeatedly inserting a needle therethrough into a cavity defined within the body. Further, the access port may include at least one feature structured and configured for identification of the access port subsequent to subcutaneous implantation. Methods of identifying a subcutaneously implanted access port are also disclosed. For example, a subcutaneously implanted access port may be provided and at least one feature of the subcutaneously implanted access port may be perceived. Further, the subcutaneously implanted access port may be identified in response to perceiving the at least one feature.

摘要： Assemblies for identifying a power injectable vascular access port are described. One assembly includes a vascular access port, a first identifiable feature, a second identifiable feature, and a third identifiable feature. The first identifiable feature is incorporated into the access port and identifies the access port as suitable for flowing fluid at a fluid flow rate of at least about 1 milliliter per second through the access port. The second identifiable feature is incorporated into the access port and identifies the access port as suitable for accommodating a pressure within the cavity of at least about 35 psi. The third identifiable feature is separated from the access port and confirms that the implanted access port is both suitable for flowing fluid at a rate of at least about milliliter per second through the access port and for accommodating a pressure within the cavity of at least about 35 psi.

摘要： A multi-lumen catheter configured for insertion into the vasculature of a patient for fluid infusion into or fluid aspiration from the patient is disclosed. The multi-lumen catheter includes one or more cross sectionally variable lumens, wherein the cross sectional area of the lumen(s) may be selectively increased, particularly during fluid infusion, in order to enable relatively greater fluid flow rate therethrough. In one embodiment, the multi-lumen catheter includes a deformable first septum for providing an increased cross sectional area for a lumen under high flow rate pressurization, such as power injection. A deformable second septum also deforms to allow for first septum deformation and additionally provides an urging force to restore the first septum to an un-deformed state once lumen pressurization has ceased. In another embodiment, a bi-positional septum is used to selectively increase the cross sectional area of a lumen of the catheter during power injection.

摘要翻译： 公开了一种构造成用于插入到患者的脉管系统中用于流体输注或从患者流体抽吸的多腔导管。 多腔导管包括一个或多个横截面可变腔，其中，特别是在液体输注期间，可以选择性地增加内腔的横截面面积，以便能够实现相对较大的流体流速。 在一个实施例中，多腔导管包括可变形的第一隔膜，用于在高流速加压（例如动力注射）下为内腔提供增加的横截面面积。 可变形的第二隔膜也变形以允许第一隔膜变形，并且另外提供推动力以在一旦腔加压停止时将第一隔膜恢复到未变形状态。 在另一个实施例中，双功能隔膜用于在动力注射期间选择性地增加导管的内腔的横截面面积。

摘要： An ion conducting device having a plurality of solid electrolyte plates arranged into a stack, each electrolyte plate having electrode material adherent to a significant portion thereof. A plurality of individual spacers are disposed between adjacent electrolyte plates in the stack, each spacer spacing successive electrolyte plates apart, and defining a plurality of chambers in the spaces between adjacent electrolyte plates. The electrode material on the electrolyte plates is electrically connected whereby electrode material on every other successive plate is connected in series, from one end of the stack to the other, whereupon the electrical path wraps around the stack and extends back along the stack and connects in series the electrodes not previously connected.
