Abstract: A guiding sheath, which is capable of causing a dilator and a sheath to integrally reach a carotid artery which is accessed from a radial artery and communicates with a target treatment site, and easily indwelling the sheath in the carotid artery that communicates with the target treatment site. The guiding sheath includes: a dilator in which an inner cavity, through which a guide wire is insertable is provided, over an entire length of the dilator and which includes a dilator distal end portion and a dilator main body portion; and a sheath which covers outside of the dilator and includes a sheath distal end portion and a sheath main body portion. The sheath distal end portion is disposed on a distal end side of the sheath main body portion and is formed of a material more flexible than a material forming the sheath main body portion.

Abstract: A puncture needle includes: a main body having a rod shape; a needle tip formed at a distal portion of the main body; and a recess formed in a side portion of the main body. The recess has a distal-side wall that has a wall surface facing a proximal side and facing a direction of being skewed at 0° or more and 75° or less from a direction along an axis of the main body to a radially outer side of the main body. The distal-side wall and a portion of the main body on a proximal side of the recess are separated from each other when the distal-side wall and the main body are viewed in a normal direction of the distal-side wall.

Abstract: A dilator (30) insertable into a catheter (20) includes a tubular shaft part (40), and a tubular flexible part (50) located on a distal end side of the shaft part (40) and formed of a resin more flexible than the shaft part (40), and includes, in the shaft part (40) and/or the flexible part (50), a physical property inclined part (42) in which rigidity gradually decreases from a proximal end side toward a distal end side. The catheter assembly is capable of achieving both stable catheter insertability into a blood vessel and reduction in risk of blood vessel perforation.

The most distal end portion is directed to a common hepatic artery and the first bent portion comes into contact with an aorta wall on an opposite side from a celiac artery when the second bent portion contacts a blood vessel wall of the celiac artery.

Abstract: A hemostatic device is disclosed, which includes a covering portion disposed so as to cover a site where bleeding is to be stopped on a hand of a patient; a pressing portion that compresses the site where bleeding is to be stopped when the covering portion covers the site where bleeding is to be stopped; a band portion wrappable around a periphery of the patient's hand at the site where bleeding is to stopped; a restriction portion that restricts movement of the securing portion in an axial direction; and wherein the pressing portion is not disposed on the centerline of the restriction.

Abstract: A hemostatic device can perform hemostasis by compressing a puncture site on a hand of a patient, and can prevent a movable range of fingers from being narrowed or can prevent misalignment at a wearing position, when the hemostatic device is worn on the hand. The hemostatic device has a covering portion to cover a site where bleeding is to be stopped on a hand of a patient, and a pressing portion that compresses the site where bleeding is to be stopped, in a state where the covering portion covers the site where bleeding is to be stopped. The covering portion includes a securing portion that surrounds at least a portion of the hand while covering the pressing portion, and a restriction portion that restricts a movement of the securing portion in an axial direction. The restriction portion is disposed between adjacent fingers and of the hand.

Abstract: An introducer sheath, which is a medical elongated body, includes: a catheter main body; a hub fixed to a proximal portion of the catheter main body; a drug portion disposed on an outer surface of the catheter main body; and a support member configured to be connected to the hub and cover the drug portion of the catheter main body, in which the support member has a base portion rotatable in a circumferential direction of the catheter main body and a covering member disposed so as to protrude from a distal end of the base portion and cover the drug portion while overlapping at least a part of the base portion in a radial direction of the catheter main body, and the covering member is configured to move relative to the catheter main body and expose the drug portion as the base portion rotates.

Abstract: An elongated medical catheter body, which may constitute an introducer sheath includes: a catheter body; a hub fixed to a proximal portion of the catheter body; and a support member connected to the hub and configured to cover of the proximal portion of the catheter body. The catheter body includes a groove on the outer surface of the catheter body, and the support member is disposed so as to partially cover the groove. The support member includes a drug part having a drug solution, and a partition wall portion is located between the drug part and the groove, and the partition wall portion is configured to make the drug part communicate with the groove portion upon being broken by pressure or by causing damage.

Abstract: A catheter includes a tubular body comprised of inner and outer layers, and an embedded reinforcement body. The tubular body includes a substantially linear main body portion and a shaped portion that is bent so the shaped portion lies in substantially the same plane. The shaped portion includes a first bent portion defining a first angle distal of the main body portion, a second bent portion defining a second angle distal of the first bent portion and bent to the same side as the first bent portion, a third bent portion defining a third angle distal of the second bent portion and bent to a side opposite the second bent portion, and a most distal portion distal of the third bent portion. A physical property changing point exists between a proximal portion of the first bent portion and a distal portion of the second bent portion.

Abstract: A catheter is disclosed that can easily reach and be engaged with a uterine artery or a prostate artery from a radial artery and a treatment method. The catheter includes a tubular body having a lumen extending from a proximal end to a distal end. The tubular body includes, at a distal portion of the tubular body, a shaped portion shaped in a manner of being bent on substantially the same plane. The shaped portion includes a proximal bent portion bent to define a first angle, a distal bent portion defining a second angle distal of the proximal bent portion, an intermediate linear portion that is linear, and a distal linear portion that is linear. A first minimum curvature radius of the proximal bent portion is greater than 3 times and less than 11 times a second minimum curvature radius of the distal bent portion.
