  • Patent number: 12161819
    Abstract: An insertion device for inserting a catheter into a patient's body is disclosed. In some embodiments, the insertion device combines needle insertion, guidewire advancement, catheter insertion, and needle shielding in a single device. In one embodiment, the insertion device comprises a housing including a hollow needle distally extending from the housing. At least a portion of the catheter is pre-disposed over the needle such that the catheter is disposed substantially external to the housing. A guidewire is included, as well as an advancement assembly that is configured to selectively advance the distal end of the guidewire out a distal opening of the needle in preparation for distal advancement of the catheter. The advancement assembly is further configured to enable distal catheter advancement before shielding the needle after use. The insertion device is configured to be grasped and used by a single hand of a user.

  • Patent number: 9033926
    Abstract: An intravascular needle and catheter arrangement that ensures flashback is indicated after the catheter is safely inserted through the needle puncture in the vascular wall and emplaced into the vessel. This placement location, at which flashback first occurs is sufficient to begin threading the catheter without risk of over-insertion or under-insertion. The catheter overlies a needle having a distal tip that defines a point. The needle tip includes an enclosed distal-most end and a port located along at least one of the proximal portion of the point and an adjacent cylindrical sidewall of the needle. The distal end of the catheter exposes the port for entry of blood from a vessel thereinto only after the distal end of the catheter has entered sufficiently into the interior of the vessel. An opposing second side of the tip defines a curved surface that prevents puncturing of the back vessel wall.

    Abstract: A Retrograde Entry Antegrade Placement (REAP™) method and apparatus facilitate the antegrade (i.e., in the direction of blood flow) placement of endovascular devices for treatment of lower extremity arterial disease. Initially, a retrograde entry is made into the arterial system of a patient at an entry point with a curved needle, which then exits at an exit point proximal to the entry point, with a first wire then passed through the lumen of the curved needle. From the skin exit point, a Dual-Lumen Access Director (DAD) device is advanced in the antegrade direction down the first wire in a first lumen and enters the CFA 1 lumen. A second wire is passed down a second lumen in the DAD device and follows the SFA lumen in the antegrade direction. The DAD device is removed, and a standard dilator sheath is inserted over the second wire and the endovascular treatment begins.

The cannula ready intravenous catheter includes a cylindrical housing that provides an uninterrupted smooth surface, for reducing skin irritation. A proximal end of the cylindrical housing provides a luer-type connector site, and a distal end of the cylindrical housing provides a catheter hub. The catheter hub supports a catheter tube, which extends from a distal end of the catheter hub.

  • Patent number: 8956328
    Abstract: A low-profile universal passive protector is provided for an IV catheter comprising a hypodermic needle and a catheter. An elongate sheath defines a sheath cavity and a longitudinal axis. A slider is connected to the hypodermic needle and is movable along the sheath between first and second positions for withdrawing the needle into the sheath. A finger-press plate is coupled to the sheath and extends beyond the slider in a direction perpendicular to the longitudinal axis to define a plate height. A flashback body is coupled to the slider in a manner such that the flashback body and slider collectively define a cavity in fluid communication with the hypodermic needle. The flashback body is sized and configured to extend from the slider in a direction perpendicular to the longitudinal axis to define a flashback body height that is less than the plate height.

  • Patent number: 8784447
    Abstract: A surgical stapler having a hollow shaft 10 and a tube 92 slidable axially within the shaft between a forward position wherein one end 96 of the tube projects beyond a free end of the shaft to enter a puncture site in a blood vessel and a rearward position wherein the end of the locator tube is retracted within the shaft. A surgical staple 40 straddles the tube 92 and is slidable thereon forwardly towards an anvil 24 against which the staple may be deformed to staple together the opposite edges of the puncture site. A cam mechanism drives the staple forwardly along the tube 92 into deforming engagement with the anvil and at the same time retracts the tube into the shaft in time to allow the legs of the staple to close onto the puncture site.

  • Patent number: 8764710
    Abstract: An apparatus for preventing blood exposure or contamination upon withdrawal of a hypodermic needle is provided. The apparatus may include a needle having a tip and a shield configured to at least partially entrap the needle tip upon withdrawal of the needle. The apparatus may further include a blood stabilizing material disposed such that upon withdrawal of the needle the blood stabilizing material is disposed in operative association with the needle tip such that blood carried by the needle is prevented from escaping the apparatus. In some exemplary implementations, the blood stabilizing material may be disposed on one or more surfaces of the shield. The shield of the hypodermic needle may include protective device and/or a housing for shielding the needle tip upon withdrawal. The housing may be adapted to at least partially cover the needle tip upon withdrawal of the needle.
