Document Type and Number:
WIPO Patent Application WO/2018/164235
Kind Code:
A1
Abstract:
[Problem] To provide an indwelling catheter which is stiff when being inserted into a vessel such as a blood vessel, softens after indwelling in the vessel, and conforms to a shape in the direction in which the vessel runs.
[Solution] In this indwelling catheter, the maximum value of a catheter repulsive force in a dry state at 25°C is at least equal to 0.10 N, the maximum value of the catheter repulsive force when immersed in warm water at 37°C is between 0.01 and 0.25 N, a ratio between the maximum value of the catheter repulsive force in a dry state at 25°C and the maximum value of the catheter repulsive force when immersed in warm water at 37°C is at least equal to 3.5, and the maximum value of the catheter repulsive force when immersed in warm water at 37°C is at most equal to 0.027 N five minutes after indwelling.
