  • Patent number: 10335196
    Abstract: Surgical instruments and methods including a stop guard are described herein. An exemplary instrument can include an inner shaft disposed within an outer shaft, the inner shaft including a tissue-piercing tip and being effective to secure an end effector to the device. A stop guard can be coupled to the inner shaft and extend through outer shaft sidewall openings when the tip is advanced distally or retract into the outer shaft when the tip is retracted proximally. In a percutaneous procedure, external force applied to the stop guard by the tissue can retract the tip to prevent damage to surrounding tissue as the instrument is advanced distally. Moreover, once passed through pierced tissue, the stop guard can be redeployed when the inner shaft is advanced distally to secure an end effector to the instrument and can prevent inadvertent withdrawal of the instrument.

  • Patent number: 10271781
    Abstract: The present invention provides a surgically invasive pointed article for skin penetration and capillary whole blood extraction whose penetration ability can be disabled after use by deforming the tips. The present invention is made by injection molding a plastic needle 35 having an anchoring means 45 using a first material, followed by another injection molding process to over-mold a first body segment 20 and second body segment 30 using a second material to encase the plastic needle 35 thereby anchoring the plastic needle 35 to prevent further movement of the plastic needle 35. The encasing of the second material provide a barrier isolating the plastic needle 35 from the ambient to protect the tips 50 from damage and once sterilized, to conserve the sterile conditions till point of use. The barrier formed by a second over-molding process comprises a detachable cap 20 and a body 30.

  • Patent number: 10265466
    Abstract: A fluid infusion device is provided with a cannula spring which functions as an introducer needle, a retraction return spring, and a fluid path. A hollow cannula tubing is wound, bent and sharpened into a shape which allows it to operate as an introducer needle, retraction spring and fluid path in an infusion device. A button is used to insert the introducer needle portion of the cannula spring and a soft catheter, and once the introducer needle portion and catheter have been fully inserted, an engagement between the button and post of the base of the infusion device releases the cannula spring such that the introducer needle portion of the cannula spring automatically retracts, leaving the catheter in the body. An end of the introducer needle portion of the cannula spring remains in fluid communication with the catheter in the body to provide an uninterrupted fluid path.

  • Patent number: 10188335
    Abstract: In some embodiments, the present invention generally relates to the separation of blood within a device to form plasma or serum. In some embodiments, the present invention generally relates to the removal of fluids, such as blood, contained within a device. In one aspect, the present invention is generally directed to systems and methods for receiving blood from a subject and processing the blood to form plasma or serum. For example, a device may be applied to the skin of a subject to receive blood from the subject and pass the blood through a separation membrane, which separates the blood into plasma and a portion concentrated in blood cells. As another example, blood or plasma may be allowed to clot within the device and serum (the unclotted portion of the blood) may be withdrawn from the device. The device may contain, in some cases, a vacuum source such as a pre-packaged vacuum to facilitate receiving of blood and/or passage of the blood through the separation membrane to produce plasma or serum.

  • Patent number: 10105086
    Abstract: A lancing device includes a housing, a lancet carrier translational within the housing, a drive spring for propelling the lancet carrier through a translational lancing stroke, and a charging mechanism. The charging mechanism includes a first cam member that is rotatable relative to the housing, a second cam member that abuts the first cam member, is coupled to the lancet carrier, and is restricted from rotation relative to the housing, and a rotatable handle co-rotationally attached to the first cam member. Rotation of the handle rotates the first cam member with it, causing the first cam member to rotate against the second cam member, which in response traverses axially because it is restricted from rotation, thereby retracting the lancet carrier to a retracted or charged state.

    Abstract: A system and method for carrying out the withdrawal of body fluid with as little body fluid as possible visible to the user at the end of the process. The present invention provides a pressure piece for exerting pressure on a body part. The pressure piece is moved relative to a support for the body part, and in the final phase of fluid withdrawal, the compressive or resistive force of the pressure piece on the body part is reduced in order to avoid the escape of body fluid from the puncture site. The support results in a defined positioning of the body part that rests against it for the lancing process, whereas the relative movement of the pressure piece enables an additional increase in pressure and thus an improved collection of fluid.

    Abstract: A method and system is provided for automatically preparing transmission electron microscopy (TEM) samples for examination by depositing extremely small samples onto a grid without need for a blotting step. A sample liquid droplet is formed at the end of a capillary, wherein a portion of the liquid is transferred to the TEM sample grid by contact. The excess volume in the liquid droplet is then retracted by an adjacent capillary. After a predetermined time interval, the retraction capillary is moved toward the drop of the sample to remove the excess volume. As compared to a conventional machine, where the blotting procedure can deform the structure of the molecule of interest, the present invention utilizes a very low shear rate for removal of the excess sample fluid.

  • Patent number: 9138185
    Abstract: A lancet assembly includes a lancet, a lancet engaging part, and a lancet case housing the lancet and the lancet engaging part. In the lancet assembly of the present invention, the lancet engaging part and the lancet cap are disposed such that they are capable of making contact with each other. When the lancet engaging part is forced to move forward with respect to the lancet in a pricking direction, the lancet cap is pressed by the lancet engaging part, and thereby the bridging component is broken so that the lancet cap is separated from the lancet body. When the lancet engaging part is forced to further move forward, the separated lancet cap moves to the position off a pricking pathway of the pricking component within the lancet case.

  • Patent number: 9033898
    Abstract: Systems and methods for delivering and/or receiving a substance or substances, such as blood, from subjects. In one embodiment, devices and methods for receiving blood from a subject employ devices including a substance transfer component (such as one or more microneedles), and a storage chamber having an internal pressure less than atmospheric pressure prior to receiving blood. In certain embodiments, substances may be received from and/or delivered to the subject with relatively little pain. The pain may be assessed, for example, using pain scales such as the WONG BAKER FACES Pain Scale. The device may be self-contained, applied to the skin, and activated to receive blood from the subject. The device, or a portion thereof, may be processed to determine the blood and/or an analyte within the blood using sensors or agents in the device or an external apparatus.

  • Patent number: 9023292
    Abstract: Disclosed herein is a device for sampling blood by capillarity for separating a plasma phase of the blood from the cell phase. The device is a strip and includes a filter having a membrane with no clumping agents, a prefilter for spreading blood over the surface of the membrane; and an absorbent paper downstream from the filter. The membrane is dimensioned to cover only a part of the surface of the prefilter and the migration of blood by capillarity within the prefilter takes place essentially lengthwise relative to the strip before blood comes into contact with the membrane.
