    Abstract: A minimally invasive surgery suction sleeve configured for use with an inner cannula of a suction instrument. The sleeve includes a first opening at a proximal end, a second opening at a distal end, and a tube between the first opening and the second opening. The sleeve slides over a suction instrument. The distal end is configured to insert into the body and includes a plurality of apertures that provide for pool suction. The sleeve further includes a flange at the proximal end that allows a surgeon to manipulate the sleeve, switching between spot and pool mode by sliding the sleeve over the inner cannula of the suction instrument. In spot mode, the tip of the suction instrument is exposed. In pool mode, the sleeve slides forward, covering the tip of the suction instrument so that fluent material is drawn through the apertures in the sleeve.

    Abstract: Catheter assembly (100) having at least one lumen (150 or 160) and joined to hub (106). While the lumen inner diameter(s) remain constant from distal end (144) of the catheter (140) to proximal end (142), the outer catheter diameter increases proximate the hub (106) providing increased resistance to kinking during connection and disconnection from medical apparatus. The increased proximal catheter diameter preferably is sufficiently large to plug the proximal end of an introducer sheath through which the catheter is inserted during patient placement, to plug the proximal sheath end and minimize blood aspiration therethrough, and later serves to fill the vascular insertion upon complete catheter insertion after removal of the introducer sheath again to minimize blood aspiration through the vascular incision. The catheter may have two lumens (150,160) or more, joined to respective extension tubes in hub (106). The two lumens may each have a respective inner diameter of between about 0.020 in and 0.025 in.

    Abstract: A device for facilitating the use or application of skin penetrators, the device including a puncturing part for piercing the skin, an indwelling part which can be introduced into the skin through an opening generated by the puncturing part and remains there, wherein the puncturing part and indwelling part are operably associated with the device, and a guide operably associated with the device, wherein, in use, the indwelling part is moved, via the guide, into a position of use after the puncturing part has pierced the skin. In some embodiments, the puncturing and indwelling parts are separate from each other prior to use. A method of using skin penetrators is encompassed and includes sequentially introducing the puncturing part and the indwelling part into the skin.

  • Patent number: 8012127
    Abstract: Systems for gaining access into a body of a patient around an implanted body of an elongate medical device include a sheath having a deformable wall that allows insertion of the device body into a lumen surrounded by the sheath wall. The sheath wall may include first and second edges that extend from a proximal end to a distal end of the lumen, or just extend along a distal portion of the lumen. A tool, which includes a groove sized to grasp about a circumference of the device body, may facilitate insertion of the device body into the lumen of those sheath embodiments that include the first and second edges, by spreading at least one of the first and second edges of the wall apart from the other of the first and second edges while the device body is grasped within the tool.

  • Patent number: 8007469
    Abstract: A catheter system for positioning an instrument within a body that includes a hub defining a lumen therethrough for passage of the instrument toward the body. The catheter system also includes an elongate tubular member defining a lumen therethrough. The lumen of the elongate tubular member is in communication with the lumen of the hub for further passage of the instrument toward the body. The system also includes a slitter member that is coupled to the hub. The slitter member is disposed to slit the elongate tubular member as the elongate tubular member moves relative to the hub.

  • Patent number: 7972313
    Abstract: A safety IV catheter includes a unitary, resilient needle guard received in a catheter hub. The needle guard includes a proximal arm or wall that includes an opening through which a needle passes for axial movement. When the needle is retracted from the catheter, it releases the force that had previously prevented movement of the needle guard within the catheter hub. This in turn causes the needle guard to snap into a position in which it is clamped onto the needle shaft and in which its distal wall blocks access to the needle tip. In this condition, the spring needle guard and needle can be removed from the catheter hub. A slot or crimp may be formed in the needle shaft that engages with the needle guard after the protected needle and needle guard are removed from the catheter hub, thereby to prevent removal of the protected needle from the needle guard.

  • Patent number: 7914501
    Abstract: Indwelling needle includes a cylindrical body, a needle having a sharp edge at a tip thereof, a cylindrical hub retaining proximal end of needle and moveable along main body, a protective cover moveable along main body and projecting from main body, and a spring elastically installed between hub and protective cover. First engaging portion of actuating lever is provided on body engaged with first projection of protective cover and second through-hole in hub to allow first retention mechanism to retain indwelling needle in a use state. First engaging portion is moved upward to release first retention mechanism. This separates protective cover and hub from each other under elastic force of spring. Protective cover and hub are thus retained in a housed state by second retention mechanism and third retention mechanism, respectively. This configuration reduces length of member contacting patient in the use state.
