摘要： A multiple lumen catheter (110,150) having at least first and second lumens (112,114; 152,154). At least one of the first and second lumens (112,152) is generally C-shaped in cross-section, with a septum wall (120,160) dividing the first and second lumens providing a generally straight side to the C-shaped cross-section. A stylet or guide wire (130) may be disposed along the C-shaped cross-section lumen (112,152,154) having a larger diameter than one used with catheters of the same outer diameter but that have lumens of only D-shaped or circular shaped cross-sections.

摘要： A clamp guard for securing to flexible tubing such as catheters and their extension tubes and about a clamp therealong for housing the clamp at least when the clamp is in a tubing-clamping state, to prevent inadvertent contact of the clamp by a foreign body and undesirable unclamping of the clamp. The clamp guard is removable from around the clamp when desired.

摘要： Embodiments of the invention are directed to a delivery device and method for deploying an optical analyte sensor. The delivery device comprises hollow tubes configured to operate telescopically. The optical sensor is configured to retract and extend from a distal end of the delivery device, by sliding the telescoping tubes with respect to one another. The delivery device may also have a locking mechanism such that the distal end portion of the sensor will extend to a preset locked position beyond the delivery device, e.g., during calibration and deployment. The device is capable of being used to ship, calibrate, and deploy the sensor while maintaining sterility and avoiding exposure to the external environment.

摘要： Catheter assembly (100) having at least one lumen (150 or 160) and joined to hub (106). While the lumen inner diameter(s) remain constant from distal end (144) of the catheter (140) to proximal end (142), the outer catheter diameter increases proximate the hub (106) providing increased resistance to kinking during connection and disconnection from medical apparatus. The increased proximal catheter diameter preferably is sufficiently large to plug the proximal end of an introducer sheath through which the catheter is inserted during patient placement, to plug the proximal sheath end and minimize blood aspiration therethrough, and later serves to fill the vascular insertion upon complete catheter insertion after removal of the introducer sheath again to minimize blood aspiration through the vascular incision. The catheter may have two lumens (150,160) or more, joined to respective extension tubes in hub (106). The two lumens may each have a respective inner diameter of between about 0.020 in and 0.025 in. The catheter body may have a lengthy distal portion vascularly implanted having an appropriate outer diameter for the vessel, and also a lengthy proximal portion with a larger diameter for resistance to kinking at a sharp bend between the vascularly implanted portion and the subcutaneously tunneled lengthy proximal portion.

摘要： A multi-lumen catheter comprising a longitudinally extending elongated body portion, with at least two septa extending longitudinally therethrough the entire body portion, defining a central lumen and two side lumens. The central lumen is of oblong shape in cross section, and is positioned between the side lumens. The septa that form the central lumen are configured to be capable of flexing outwards when the central lumen is under pressure, such as when used in procedures that require power injection, whereby a cross sectional area of the central lumen resultantly increases to increase flow capacity through the central lumen. In some embodiments, the central lumen has a defining inner surface such that a radius of curvature of the central lumen inner surface is, in all locations, equal to or greater than a radius of curvature of an outer surface of a guide wire used for insertion of the multi-lumen catheter. The septa are each configured to fail under pressure before failure of the outer wall.
摘要翻译：一种多腔导管，其包括纵向延伸的细长主体部分，其中至少两个隔片纵向穿过整个主体部分延伸，限定中央腔和两个侧腔。中央腔的截面长椭圆形，位于侧腔之间。形成中央腔的隔膜被构造成当中心腔处于压力下时能够向外弯曲，例如当在需要动力注射的程序中使用时，由此中心腔的横截面积最终增加以增加流量通过中央腔。在一些实施例中，中央腔具有限定的内表面，使得中心腔内表面的曲率半径在所有位置都等于或大于用于插入的导丝的外表面的曲率半径的多腔导管。隔垫各自被配置为在外壁失效之前在压力下失效。
