Title:
カテーテル組立体
Document Type and Number:
Japanese Patent JPWO2005056100
Kind Code:
A1
Abstract:
A catheter assembly (1), including an outer catheter (2) and an inner catheter (6) capable of being inserted into the outer catheter (2). The catheter assembly is characterized in that an outer catheter hub (5) and an inner catheter hub (9) are fixedly fitted to each other so that the two catheters are not rotated nor moved relative to each other, and when fitted to each other, at least a part of the tip of the inner catheter (6) is protruded by 10 mm or shorter from the tip of the outer catheter (2). When the inner catheter is inserted into the outer catheter, operabilities such as kink resistance, press-in performance, and torque transmission performance are excellent and the inner diameter thereof is increased when the catheter is used after indwelling. As a result, the range of choices of a catheter for treatment can be increased.
