摘要： A medical instrument comprises a substrate which has at least on its surface a reactive functional group covalently bonded with a water-soluble polymer or derivative thereof, whereby said surface has lubricity when wetted. The water-soluble polymer is a cellulosic polymer, maleic anhydride polymer, polyacrylamide or water-soluble nylon. The medical instrument is prepared by treating a substrate with a solution of a compound having a reactive functional group to form an undercoat so that the reactive functional group is present at least on the substrate surface, and then treating the substrate with a water-soluble polymer or derivative thereof to covalently bond the reactive functional group with the water-soluble polymer to thereby form a coat of the water-soluble polymer on the undercoat and optionally, contacting the treated substrate with water.

摘要： In a catheter comprising a proximal inner tube having a reinforcing layer applied thereto and a distal inner tube made of a material having different physical properties from those of the proximal inner tube. the proximal and distal inner tubes are axially integrally connected such that the outer surface of the proximal inner tube is substantially smooth and continuous to that of the distal inner tube, and a sheath continuously covers the proximal and distal inner tubes. The catheter is produced by axially integrally joining proximal and distal inner tubes and continuously covering the interconnected tubes with a sheath.

摘要： A catheter introduced into the pulmonary artery for use in measuring cardiac output or blood flow velocity includes temperature sensing device including a temperature sensing element for sensing the temperature of blood in the pulmonary artery diluted by an indicator liquid infused for measurement of cardiac output based on a thermodilution method, and a self-heating thermistor for sensing a signal relating to blood flow velocity near the temperature sensing element, the signal being an equilibrium temperature sensed by the thermistor. The catheter is connected to a cardiac output measurement system adapted to measure cardiac output on the basis of the thermodilution method, measure the blood flow velocity which prevails when the cardiac output is measured, and obtain a parameter which links this blood flow velocity to the cardiac output measured in accordance with the thermodilution method. Once the parameter is found, merely measuring the blood flow velocity enables cardiac output to be determined from the flow velocity and the parameter.
