    • Apparatus and a method for monitoring a percentage of the oxygen saturation in the hemoglobin of blood flowing through a blood vessel. An optical sensor that detects the percentage oxygen saturation in blood is disposed proximate a proximal end of the catheter. A thermistor is disposed adjacent to the distal end of the catheter and it is employed to detect changes in blood temperature that indicate the position of the catheter's distal end in the blood vessel. Indicia or marks visible at intervals on the outer surface of the catheter enable a medical practitioner to determine the length of the catheter that has been introduced into the blood vessel. A strain relief that is flexible and resists stretching extends along the length of the catheter. For flushing the distal end of the catheter, a fluid supply may be connected to a lumen running through the catheter to provide the flushing fluid. A removable guide wire is inserted in the lumen when positioning the distal end of the catheter at a location in the blood vessel and provides enhanced rigidity for this purpose. The catheter may be coated with an anticoagulant such as heparin, to prevent blood from coagulating on the exterior surface of the catheter.
    • 用于监测流过血管的血液的血红蛋白中的氧饱和度百分比的装置和方法。 检测血液中氧饱和度百分比的光学传感器设置在导管近端附近。 热敏电阻设置在导管的远端附近,并且用于检测指示导管远端在血管中的位置的血液温度变化。 在导管的外表面上以间隔可见的标记或标记使医生能够确定已经被导入血管的导管的长度。 柔韧且抗拉伸的应变消除部沿着导管的长度延伸。 为了冲洗导管的远端,流体供应可以连接到穿过导管的内腔,以提供冲洗液。 当将导管的远端定位在血管中的位置时,将可移除的导丝线插入内腔,并为此提供增强的刚性。 导管可以用抗凝血剂如肝素涂覆,以防止血液凝结在导管的外表面上。

    • This is a catheter assembly which may be used in accessing a tissue target within the body, typically a target which is accessible through the vascular system. Central to the invention is the use of a braided metallic reinforcing member, typically of a stainless steel or super-elastic alloy ribbon, situated within the catheter body in such a way to create a catheter section having a thin wall, controlled stiffness, and high resistance to kinking. The distal-most section of the catheter is much more flexible than are other braided catheters of the genre due to choice of braid construction features of that distal-most section. The distal-most braid, and optionally, intermediate braid components are constructed to be more flexible than the more proximal sections due to deletion of ribbons from the braid structure, change of ribbon material, and change of pitch. The various sections include braids which may have a consistent pitch or may vary in pitch along the axis of the catheter or catheter section. The braided ribbon reinforcing member typically is placed between a flexible outer tubing member and an inner tubing member to produce a catheter section which is very flexible but highly kink resistant. The more proximal sections of the catheter assembly are often substantially stiffer than the more distal sections also due to the presence of stiff polymeric tubing or composited materials in the stiffer section.

    • A multi-lumen, multi-purpose cardiac catheter which incorporates optical filaments and an optical coupler for use with external apparatus for determining the oxygen concentration in the blood of a patient under critical care conditions, as well as incorporating therein a thermal element useable with a second external apparatus for measurement of continuous cardiac output. The thermal element is disposed at a necked down portion of the catheter at the distal end thereof, with at least one of the lumens of the catheter substantially compressed at the necked down portion thereof. The catheter also includes a thermistor and at least one injectate port for enabling the user to also conduct thermal dilution readings and obtain intermittent measurements of cardiac output. The combination of a thermal dilution catheter with a SVO.sub.2 catheter and a continuous cardiac output catheter gives the multi-purpose catheter above described substantial versatility as well as providing the user with a versatile cardiac catheter device which enables him to conduct multiple evaluations of disparate blood-related parameters which require the use of separate apparatus. Simply by switching from one external apparatus to the other, the user can obtain readings for different blood-related parameters useful in the treatment of the cardiac patient.

    • A catheter for use in vasculature or other lumens within body structures includes a shaft formed from an elongated polymeric flexible tube. A thin polymeric sleeve is placed over a proximal portion of the catheter shaft. A hub structure is injection molded over the sleeve with a polymer of the same type as the polymeric sleeve. The heat from the injection molded polymer of the hub body is sufficient to heat the polymeric sleeve, causing the polymeric sleeve to bond the hub body to the sleeve, and the sleeve to the catheter shaft. In this way, the injection molded polymeric hub structure is fused to the catheter shaft, with a unified polymeric bond, and without the use of adhesive. The plastic sleeve is sufficiently thick to protect the catheter shaft from the heat of the injection molded molten polymer while still allowing the catheter shaft and sleeve to bond to the shaft.
