  • Patent number: 10695175
    Abstract: A guide catheter is described for introduction into a patient's vasculature, to provide a substantially continuous guide lumen within the vasculature to the ascending aorta, through which one or more other functional catheters may be introduced and removed during the procedure. The guide catheter includes an aligner at its distal region for aligning the position and/or inclination of the distal region of the guide catheter with respect to the ascending aorta. The aligner includes an embolic protection filter. The guide catheter is made of material collapsible/distensible in cross section to adopt a small shape when no catheter is present inside, and to distend to a large shape to accommodate passage of functional catheter therethrough. The cross-section shape collapses/distends by folding/unfolding of material without elastic stretching of the material.

An end effector assembly is included that extends distally from the outer shaft in a deployed position of the end effector assembly. A first actuator is operably associated with the housing and actuatable to deploy and retract the end effector assembly. A second actuator is operably associated with the housing and actuatable to move a four-bar articulation mechanism including first, second and third movable links and a stationary link coupled together by respective first, second and third pivots. Actuation of the second actuator moves the first link distally which forces the second and third links to rotate in opposing directions about the first and second pivots which, in turn, forces at least one of the first or second links against the end effector assembly to articulate the same.

  • Patent number: 10383656
    Abstract: An introducer needle assembly including a compressible section between the rigid needle and the hub. Once the vessel is entered as determined by blood entering the syringe, the compressible section of the introducer needle is occluded by compressing the section with the thumb and a finger. Neither blood nor air can pass. Since the compressible section is in a flattened area it is easier to hold the needle while the syringe is unscrewed. The operator then can begin threading a guidewire down the device which is now easier to enter because blood is not coming out of the hub thus obscuring the lumen.

  • Patent number: 9132266
    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.

  • Publication number: 20150141819
    Abstract: A sphenocath including a sheath assembly including a sheath hub with a sheath tube extending therefrom with a passage extending from a proximal end of the sheath hub to a distal end of the sheath tube; a catheter assembly including a catheter hub with a catheter tube extending therefrom with a passage extending from a proximal end of the catheter hub to a distal end of the catheter tube; wherein the catheter assembly passes through the sheath assembly with a portion of the catheter hub engaging a portion of the sheath hub to limit relative rotation between the hubs while permitting relative axial movement such that in an initial non-extended position the distal end of the catheter tube is proximate to the distal end of the sheath tube. A system further including a guidewire is also provided. A method of inserting the catheter tube is also provided.

  • Publication number: 20150141738
    Abstract: A sheath device for inserting a catheter into a patient's body is described. The device has a first sheath with a proximal end and a distal end. When the device is used as intended, the distal end of the first sheath is provided for arrangement in the patient's body and the proximal end of the first sheath is provided for arrangement outside the patient's body. The first sheath comprises a tubular section and a sheath housing, which is disposed at the proximal end of the section and has a receiving channel for a strand-shaped body. The device solves the problem of reliably fixing a second sheath or a catheter with respect to the first sheath by providing a clamping element on the receiving channel for fixing a strand-shaped body in the receiving channel by way of clamping.

  • Publication number: 20150126930
    Abstract: A sheath can include a sheath body and a sheath hub. The sheath body can have a generally flexible tubular structure, a proximal end, and a distal end. The sheath body can further define a longitudinal axis. The sheath hub can attach to the proximal end of the sheath body and define a longitudinal axis generally aligned with the axis of the sheath body. The sheath body and sheath hub can also form a central cavity along their respective axes. The sheath hub can include two plates: a flexible plate and a rigid plate. The rigid plate can have a relief generally centered on the sheath body's axis. Advantageously, the flexible plate and rigid plate can overlap to substantially seal the central cavity.

  • Publication number: 20150059768
    Abstract: A procedure and kit are provided for performing an ultrasound-guided transversus abdominis plane (TAP) procedure. The patient's abdomen is scanned with an ultrasound probe to identify and mark the external oblique, internal oblique, and TAP. An introducer sheath is placed over a fluid delivery needle such that the distal end of the needle extends beyond the distal end of the sheath, the needle having echogenic properties for ultrasound imaging. The needle and sheath are ultrasonically guided into the TAP. A local anesthetic or saline/anesthetic combination is injected through the needle to create a liquid pool in the TAP. The needle is removed from the sheath while maintaining the sheath within the TAP and a catheter is subsequently advanced through the sheath and into the pooled liquid in the TAP. The sheath is withdrawn while maintaining the catheter located within the TAP.

A front locking member has an inner hole into which the catheter is inserted, is detachably assembled to the front connector, and is disposed inside the adjustment tube. A rear connector is assembled to the rear end of the adjustment tube. A rear locking member is connected to the catheter and detachably assembled to the rear connector, and extends through the connectors. A cap member is detachably assembled to the rear locking member. Blood clots, abscesses, and blood fluids are simply and safely removed from the human body in a short time using the catheter.

  • Patent number: 8936575
    Abstract: A needle tip shielding mechanism is described herein. The shielding mechanism comprises an outer housing, an inner housing, and a needle having a needle feature. Generally, the outer housing comprises at least one adapter-interlock feature. Moreover, the inner housing comprises a needle-feature capture mechanism, such as a washer feature, and a needle-tip capture mechanism, such as duckbilled tip barrier. In some cases, the inner housing is slidably moveable within the outer housing. In such cases, the inner housing is movable between a first position that biases the adapter-interlock feature into an engaged position and a second position that allows the adapter-interlock feature to move to an unengaged position. This ability to bias the interlock feature in the engaged position and to allow the interlock feature to move to the unengaged position allows the shielding mechanism to be selectively coupled to and released from an interlock-feature mating component within a catheter adapter.
