Abstract: A noncircular inner lumen guiding catheter with assisted variable support has an inner wall defining a noncircular cross-sectional shaped lumen for use in delivery of multiple microcatheters or other devices for treatment of neurovascular defects, such as for treatment of aneurysms. The noncircular inner lumen guiding catheter with assisted variable support includes torque transmittal guidance walls that are flexible linearly but not circumferentially, and that are neither collapsible nor kinkable. The noncircular shaped cross-section of the inner lumen may extend along the entire length of the catheter or a portion thereof, including distal or proximal.

Abstract: A conventional syringe includes a syringe barrel having a syringe barrel flange laterally extending from an open proximal end of the syringe barrel and a syringe plunger for advancement into the syringe barrel through the open proximal end. A foldable finger flange for such a syringe comprises an attachment member configured to be removably mounted onto the syringe barrel flange, and a flange member pivotably attached to the attachment member. At least a portion of the flange member is pivotable between a use position, wherein said portion of the flange member extends generally perpendicular to the syringe barrel, thereby providing a flange having a greater extent than the syringe barrel flange, and a non-use position, wherein said portion of the flange member does not extend generally perpendicular to the syringe barrel.

Abstract: A drive device of an infusion syringe piston drive head for moving an infusion syringe piston is described. The device includes an advancing means including an advancing slide, an advancing spindle and a multi-part advancing spindle nut having at least one radially movable nut shell, and a blocking means adapted to be automatically triggered by a control sensor for blocking an infeed motion of the drive head in which the advancing slide is drivable by the advancing spindle nut at the advancing spindle and in which the drive head is arranged at the advancing slide, wherein the blocking means adapted to be automatically triggered by a control sensor includes the multi-part advancing spindle nut for blocking the infeed motion of the drive head on the advancing spindle.

Abstract: A hub can be displaced between an initial position at which the hub is located on a front end side of an inner cavity of a shield and an inner needle penetrates an outer needle and a retracted position at which the hub is located on a rear end side of the inner cavity of the shield and the inner needle is housed within the inner cavity of the shield. A stopper includes an insertion portion that is inserted into the inner cavity of the shield and a base portion that is located on a rear end of the insertion portion. The base portion includes a roof portion that exposes part of an outer circumferential face of a tube connected to the hub and covers the remainder thereof, and a pair of grasping portions that are arranged to sandwich the tube and can be elastically displaced so as to grip the tube.

Abstract: An improved injection dart is disclosed. A flow restrictor positioned at a forward end of a dart body is provided. The flow restrictor has a generally cylindrical restrictor body portion and a radially outward extending flange portion at a forward end thereof. The flange is securely held in position. The restrictor body also having a recess in a rearward end. The flange portion holds said restrictor in a position where an inner bore of a cannula is precisely aligned with the restrictor bore. The restrictor acts to diminish a variable flow rate so that all flow rates above a maximum flow rate are restricted to be less than the maximum flow rate. The flange also keeps a forward end of the flow channel bore open but allows for radially inward deformation of the restrictor at a rear end of said flow channel bore.

Abstract: A puncture device comprising a hollow needle, a fixing portion fixed to the hollow needle, a sheath portion covering a part/entirety of the hollow needle and including a plastically deformable elongating member, a holding portion holding the hollow needle and the sheath portion in an integrated manner, with the holding portion positioned between the tip portion of the hollow needle and the plastically deformable elongating member, a holding release mechanism that releases the holding of the holding portion between the hollow needle and the sheath portion after the hollow needle and the sheath portion puncture the living body. The sheath portion elongates and is held in an elongated condition when the holding portion moves by the holding release mechanism, or when the holding of the hollow needle using the holding portion in an integrated manner is released, and the elastic portion contracts.

Abstract: An intravenous catheter device is provided which includes an integrated adhesive strip whereby to secure the catheter adapter to the skin of a patient following catheterization. Some aspects of the present invention further comprise an adhesive strap that is coupled to the catheter adapter of a catheter assembly. One end of the adhesive strap is removed from the catheter adapter and wrapped around a body part or surface of the patient, and secured back to the catheter adapter. Thus, the catheter assembly is secured to the patient via the adhesive strap.

Abstract: The present disclosure provides adapters configured to interconnect a device connector of a medical device and a tube connector, the adapter having a first end with a female Luer connector and a second end having a primary Luer male connector, with a secondary female section.

Abstract: A protector includes an outer tube and an inner tube. The outer tube includes an outer tube main body including an outer tube lumen for housing a puncture device, a holding part for holding a hub, and an extended part extended from the holding part. The inner tube includes an inner tube main body and a lumen inclined part. The inner tube main body is held in a proximal end side of the outer tube lumen and is movable in a proximal end direction of the outer tube lumen. The inner tube main body includes an inner tube lumen into which a tube is inserted. By moving the inner tube in a distal end direction, the inner surface of the lumen inclined part is abutted against the extended part, and the extended part is biased by the lumen inclined part in a direction in which a diameter of the tube is reduced.
