  • Patent number: 10792470
    Abstract: A method of making a flexible medical article or tube, for example, a sheath for a vascular access device, is provided. The method can include extruding a polymer, for example, a polycarbonate-urethane copolymer, to form a tube and annealing the extruded polymer. The method can further include cutting the extruded tube to a desired length before or after annealing, flaring one end of the annealed tube and over-molding the flared portion onto a hub, and forming the other end of the tube into a tip. A sheath formed by such a method is also provided.

  • Patent number: 10682157
    Abstract: An access device for placing a medical article within a body space includes a needle, a dilator, and a sheath. The dilator can be coaxially and slideably disposed about the needle, and the sheath can be coaxially and slideably disposed about the dilator. The access device can further include a inner member coaxially disposed between the needle and dilator. The needle can include a fenestration in fluid communication with a space between the needle and inner member. When the needle punctures a blood vessel, the fenestration allows blood to flow into the space between the needle and inner member to provide a visual indicator to a physician or healthcare professional that the needle is in a vessel.

  • Publication number: 20200171273
    Abstract: An anchoring system secures a catheter to the body of a patient and arrests axial movement of the catheter without impairing fluid flow through the catheter. The anchoring system can include an anchor pad that adheres to the patient's skin and supports a retainer. The retainer can include interengaging structure that moves the retainer between an open and a closed position. When in the open position, the retainer can receive a portion of the catheter and be subsequently moved to the closed position. The interengaging structure can allow the retainer to receive catheters of various sizes. The retainer can include one or more retention mechanisms to further inhibit axial movement of the catheter relative to the retainer when the catheter is secured therein. The anchoring system can include a mount that allows the retainer to rotate relative to the anchor pad.

  • Publication number: 20200094022
    Abstract: An access device for placing a medical article within a body space includes a syringe, a needle, and a sheath which are employed together with a guide wire. The sheath can be coaxially and slideably disposed about the needle. During insertion of the sheath over the needle, guide wire and into the body space, the syringe provides a negative pressure to ensure that any air located between the inside diameter of the sheath and the outside diameter of the needle is drawn into the needle rather than into the body space. In certain embodiments, a dilator is coaxially and slideably disposed about the needle and within the sheath.

  • Publication number: 20190381261
    Abstract: A sheath is provided for enclosing at least a portion of a catheter hub or other medical article to inhibit access to a lumen through the catheter hub. The sheath may comprise one or more portions that can be folded, wrapped, or otherwise positioned over or around the catheter assembly. The sheath could be used on a variety of medical articles including: a needleless valve or connector; an overlying cap on top of the valve or connector; administration tubing; a side port or connector on the side port; and any overlying cap on the side port or connector.

  • Publication number: 20190351192
    Abstract: An access device places a medical article within a body space of a patient. The device has a needle that includes an elongated body and a needle hub. The device further includes a dilator disposed on and slideable along the elongated body of the needle and a medical article. The medical article is disposed on and slideable along the dilator. A track extends in a proximal direction from the dilator. The needle hub slides along at least a portion of the track between a first position and a second position. The device further includes a locking mechanism operably disposed between the track and the needle hub so as to inhibit further axial movement of the needle in the proximal direction when the needle hub is in the second position.
