  • Patent number: 11642113
    Abstract: There is presented an interventional device (100), such as a device for minimally invasive surgery, comprising a bag arranged for being transformable between an open configuration and a closed configuration, a shaft (106), a grasper (108) mounted on a distal end of said shaft, wherein the bag further comprises a fluid passageway arranged so that in the closed configuration the fluid passageway enables that fluid may be expelled through the fluid passageway from an interior volume of the bag to an exterior volume of the bag and furthermore enables that a solid element above a predetermined threshold size may be retained in the bag. The fluid passageway may be advantageous for enabling that liquid may be expelled from the bag while larger solid elements, such as a piece of a tumour, may be retained in the bag for removal from a body cavity.

  • Publication number: 20080255523
    Abstract: A medical syringe apparatus includes a syringe unit, a hypodermic needle attached to the syringe unit and at least one interfacing member for mating a labeled medication container to the syringe unit. A filling needle is attached to the syringe unit for drawing fluid from a container. A movable needle sheath protects the hypodermic needle when not in use and may be moved out of the way when administering an injection. The medication label is visible. The container remains mated to the syringe when the syringe is in use. Risk of mislabeling the syringe may therefore be substantially reduced or eliminated and patient safety may accordingly be improved.

  • Patent number: 6866653
    Abstract: A syringe, which may be pre-filled, and a method of using the syringe is disclosed to provide sequential injection of two different fluids without mixing thereof. The syringe comprises in a first version a plunger and an intermediate disc sealingly disposed within a generally cylindrical barrel, with an outlet portion distal of the barrel, the outlet portion being generally larger in diameter so that as the disc is advanced into it far enough to substantially inject the first fluid the disc loses sealing engagement and the second fluid is then expelled around the disc and through the syringe opening. Baffles are provided within the outlet portion to prevent the disc from inadvertently sealing the opening, and channels may be provided around the baffles.

  • Patent number: 6764468
    Abstract: A sealed sterile intravenous catheter and needle assembly providing a substantially closed and sterile environment. The sealed sterile intravenous catheter is removably secured to a needle assembly and includes a tubular catheter portion, a catheter nozzle portion, and a gel cap portion aligned axially about a central axis to form a sealed flow passageway therethru. The gel cap portion includes a hollow gel cap hub having a gel cap formed of an elastic material to substantially seal the gel cap portion of the sealed catheter. Additionally, the needle assembly includes a needle configured to matingly cooperate with the sealed catheter assembly and pierce through the gel cap and sealed flow passageway of the sealed catheter assembly in a fully extended position. The needle will also be structured to fully retract for safe disposal after use.

  • Publication number: 20030060772
    Abstract: A safety needle assembly which is adapted for blunting of both an intravenous puncture tip and a non-patient puncture tip is provided. The needle assembly includes a cannula having a first end with an intravenous puncture tip and a second end with a non-patient puncture tip, and a blunting member in concentric relation with the cannula which includes a first blunt end proximate the intravenous puncture tip of the cannula and a second blunt end proximate the non-patient puncture tip of the cannula. An actuator is in engagement with the blunting member and the cannula. Activation of the actuator causes blunting of the intravenous puncture tip and the non-patient puncture tip by the blunting member. The needle assembly is particularly useful in connection with a blood collection system.

  • Publication number: 20020193736
    Abstract: A single use syringe (10) has a needle (14) which is brased back into the barrel (11) but which is prevented from doing so by a holding means (26) which has an outer part (25) and an inner part (27) which are connected together by a frangible portion (29). The needle (14) is held by the inner part (27). When the plunger (13) is pushed towards the front of the barrel (11), it contacts the outer part (25) pushes it forwardly which stretches the frangible portion (29) until it bursts. When the frangible portion (29) breaks, the inner portion (27) containing the needle (14) is released and can shoot back into a hollow portion (15) in the plunger (13) through a frangible portion of the plunger head (12).

  • Publication number: 20020065490
    Abstract: The syringe for transferring a medical substance from a container (10) provided with an elastomeric closure into an infusion container has a plastic syringe body (1). In order to avoid the danger of injury to a user by medical hollow needles previously used on syringes, a plastic hollow peg (9) is arranged at the front end of the plastic syringe body (1) instead of the typical sharp hollow needle. However the plastic hollow peg (9) is formed so that it can pierce the elastomeric closure (11) of the container (10). The hollow peg (9) is preferably in one piece with the syringe body (1). A transfer arrangement including a syringe (1), a preparation container (10) and a holder (10a) that holds the syringe on the preparation container is also described.

  • Publication number: 20010053895
    Abstract: The over-the-needle catheter is provided with a septum seal within the hub of the catheter. The introducer needle passes through the septum seal and into the catheter. Upon removal of the introducer needle, the septum seal reseals so that blood is prevented from flowing from the patient out of the hub. A male luer adaptor is used to form a connection, for example, to an IV bag by pushing the seal onto a tube secured within the hub and communicating with the catheter or, in another embodiment, by pushing a piercing ring through a slit in the septum seal to form a permanent lumen.
