  • Publication number: 20230085830
    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.

  • Patent number: 11590316
    Abstract: A catheter for a hepatic artery introduced from an arm of a patient includes a first bent portion, a second bent portion distal of the first bent portion and bent to the same side as the first bent portion, a third bent portion disposed on a distal side of the second bent portion and bent to an opposite side from the second bent portion, and a most distal end portion disposed distal of the third bent portion, in which a minimum radius of curvature of the first bent portion is larger than a minimum radius of curvature of the second bent portion. 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.

  • Patent number: 11291805
    Abstract: A medical elongated body and a medical elongated body set are constructed in a way that expedites medical instrument insertion into a tubular body lumen via a valve body. The medical elongated body includes a tubular body insertable into a body lumen, a hub having an internal space communicating with a lumen of the tubular body and disposed in a proximal portion of the tubular body, a valve body disposed in the internal space and having an insertion portion, and a cap member that fixes the valve body in the internal space by being attached to the valve body and has a proximal opening portion to communicate with the internal space via the insertion portion. The cap member has a marker portion that guides a medical instrument inserted into the tubular body to the valve body. The marker portion has a color distinguishable from a periphery of the marker portion.

  • Publication number: 20210186520
    Abstract: A hemostatic device includes a covering member configured to cover a site where bleeding is to be stopped on a hand of a patient, a securing member configured to secure the covering member to the hand, an inflatable member connected to the covering member and inflatable by a fluid, and an auxiliary member having a smaller outer shape than the inflatable member. The covering member includes a body, a first arm protruding from a first side of the body, and a second arm protruding from a second side facing the first side. The body includes a first end portion located on a distal side of the body and a second end portion located on a proximal side thereof. The inflatable member is connected to the second end portion, and the auxiliary member is connected to the first end portion and is interposed between the body and the inflatable member.

  • Publication number: 20210145452
    Abstract: A hemostatic device includes a covering member having a main body connected to an inflatable member, a first arm portion extending from the main body, and a second arm portion extending from the main body in a direction different from a longitudinal direction of extent of the first arm portion. The first arm portion is configured to be secured to the second arm portion by virtue of a part of the first arm portion passing between fingers of a patient while the second arm portion is wrapped around a limb of the patient. The second arm portion has a belt portion for wrapping around the patient's limb and a support portion connecting the main body and the belt portion and located on a straight line connecting the first arm portion and the inflatable member. The belt portion is securable to the support portion while wrapped around the patient's limb.
