Abstract
Provided are a catheter device and a catheter package which are capable of preventing a bend from being formed in a catheter body. The catheter body includes a wire state discrimination portion which discriminates a protruding state and a non-protruding state, in which the wire state discrimination portion includes a stopper which allows a transition from the protruding state to the non-protruding state, and blocks a transition from the non-protruding state to the protruding state.
Claims15
A catheter device comprising:
- a flexible catheter body which has a distal end opening and a proximal end opening, is inserted into a body cavity starting from the distal end opening, and includes a wire insertion passage provided therein;
- and
- a wire which has a higher rigidity than the catheter body, is inserted into the wire insertion passage, and includes a distal end portion and a proximal end portion, in which the distal end portion is formed in a curved shape,
- wherein the catheter body includes a wire state discrimination portion which discriminates a protruding state in which the distal end portion of the wire protrudes from the distal end opening, and a non-protruding state in which the distal end portion of the wire does not protrude from the distal end opening, and
- the wire state discrimination portion includes an allowing and blocking member which allows a transition from the protruding state to the non-protruding state, and blocks a transition from the non-protruding state to the protruding state.

A catheter package comprising:
- a catheter device;
- and
- a package body which accommodates the catheter device,
- wherein the catheter device includes a flexible catheter body which has a distal end opening and a proximal end opening, is inserted into a body cavity starting from the distal end opening, and includes a wire insertion passage provided therein, and a wire which has a higher rigidity than the catheter body, is inserted into the wire insertion passage, and includes a distal end portion and a proximal end portion, in which the distal end portion is formed in a curved shape, and
- the catheter device is accommodated in the package body in a protruding state in which the distal end portion of the wire protrudes from the distal end opening.
