摘要： A balloon catheter includes: an outer cylinder shaft having flexibility; an inner cylinder shaft having flexibility and inserted into the outer cylinder shaft; a balloon fixed to the outer cylinder shaft, that inflates or deflates in the transverse direction due to the pressure of an internal fluid supplied through the space within the outer cylinder shaft; and a securing member provided on the outer peripheral side of the balloon, whose diameter expands or contracts in the transverse direction independently of the balloon, due to the mutual movement of the outer cylinder shaft and the inner cylinder shaft in the longitudinal direction thereof; wherein the distal end portion of the inner cylinder shaft and the distal end portion of the securing member are fixed to each other, and the distal end portion of the outer cylinder shaft and the rear end portion of the securing member are fixed to each other.

摘要： A filter device is capable of reliably capturing emboli and air bubbles and reliably removing the captured emboli out of the body. The filter device includes: a first tube; a second tube protruding from the first tube; a filter arranged such that the distal end side of the filter in the longitudinal direction forms an opening; a ring fixed to the opening; first wires protruding from the distal end side of the first tube in the longitudinal direction thereof; and second wires protruding from holes in the first tube and fixed to the ring; wherein the opening can be opened and closed in the form of a bag when the proximal end side of the filter in the longitudinal direction is defined as the bottom, and the opening can be closed by pulling the second tube towards the proximal end side in the longitudinal direction.

摘要： An access port can be connected to a catheter and includes a port body including a liquid storage portion and a diaphragm body covering the liquid storage portion. The port body includes a connection passage connected to the liquid storage portion and allows the liquid storage portion to communicate with the inside of the catheter. In the cross-section along the axial direction of the connection passage at the connection position where the connection passage is connected to the liquid storage portion, the length in the direction perpendicular to the axial direction between the surface of the diaphragm body on the side opposite to the liquid storage portion and the inner surface of the liquid storage portion gradually decreases as it proceeds away from the connection position in the inclined region exceeding half of the liquid storage portion along the axial direction.

摘要： A filter device includes: a core member; a push member; first, second and third tubes; a first restriction member disposed on the first tube and configured to restrict a pushing movement of the third tube to the distal direction; a filter; a ring fixed to the opening; first and second wires, wherein the filter is configured in such a manner that the diameter of the opening is reduced by deformation of the shape of the ring, the deformation being caused by the first wires and the second wires when the push member fixed to the core member is pushed with the push member in contact with the second tube, and in such a manner that the diameter of the opening is expanded by restoration of the ring to the original shape, the restoration being caused by separating the push member fixed to the core member from the second tube.
