  • Patent number: 11660434
    Abstract: An expandable introducer sheath with an interlock dilator. The present technology provides an expandable sheath with a step feature inside its distal opening, and a dilator with an interlock that includes a catch surface configured to engage with the step feature and resist further relative movement so that the body of the dilator is prevented from exiting the distal end of the expandable sheath. This interlocking engagement may allow the dilator to be used to extend and maintain tension on the expandable sheath during insertion into a patient, and then to be retracted from the expandable sheath by pulling the dilator in the opposite direction. The present technology also provides a dilator hub with a spring mechanism configured to achieve and maintain a desired tension on the expandable sheath and to prevent overextension of the expandable sheath when the dilator is being inserted into the expandable sheath.

The grip slides independently of the wing assembly, which is not slidable with respect to the body. The grip and the needle holder are secured to one another, so that sliding movement of the grip induces sliding movement of the needle holder. The grip and the needle holder are slidable between a distal position, in which a sharp distal tip of a needle held in the needle holder is exposed, and a proximal position, in which the sharp distal tip is not exposed.

  • Patent number: 9072475
    Abstract: A needle comprises an elongated first shaft element with a C-shaped cross section and an elongated second shaft element with a C-shaped cross section. The first shaft element and the second shaft element are adapted to be detachably connected to each other. This is achieved by an overlap of respective end sections of the first and second shaft elements. Within the channel formed by the shaft elements, an optical probe may be accommodated from which the shaft elements may be removed by separating the two shaft elements from each other.

  • Patent number: 9022984
    Abstract: An apparatus for delivery of an elongate member into the lumen of a trans-dermal catheter. In a preferred embodiment, the apparatus comprises a protective sheath configured to at least substantially surround an elongate member; and slidable member configured to travel along the protective sheath, the slidable member operatively coupled to the elongate member; wherein the elongate member is insertable into a lumen of a trans-dermal catheter by moving the slidable member along at least a part of the length of the protective sheath.

  • Patent number: 8951595
    Abstract: A drug delivery balloon is provided, the a balloon having an outer surface, and a tunable coating disposed on at least a length of the balloon surface. The tunable coating includes a first therapeutic agent and a first excipient, and can include a second therapeutic agent and a second excipient. The first and second therapeutic agents have different dissolution rates during balloon inflation and therefore provide a coating that is tunable.

  • Patent number: 8753313
    Abstract: An improved splittable medical device introducer designed to introduce a medical device such as a lead or catheter, into a patient's vasculature without loss of blood or introduction of air is described. The introducer assembly is designed with a notch provided at the proximal end of the introducer housing. The notch, which may comprise a multitude of cross-sectional geometries, is designed to reduce the force required to separate the housing and the introducer sheath, thereby minimizing the possibility of unintentional dislodgement during separation. The notch also increases the repeatability and consistency of the amount of force required to separate the introducer housing and sheath.

  • Patent number: 8382714
    Abstract: A rail-guided epidural-spinal needle, which includes an epidural needle including a base and a needle shaft connected to the base, the needle shaft having a groove that is formed on an outer surface of the needle shaft and extends along an axis of the needle shaft, the base having an elevated spinal needle inlet disposed thereon, the spinal needle inlet having a conduit formed therein, the conduit being of an acute angle with the groove in a side view of the epidural needle, and being in alignment with the groove in a top view of the epidural needle. The rail-guided epidural-spinal needle also includes a spinal needle having a tip with a unilaterally curved conformation down one side, such that, when the spinal needle is inserted into the conduit of the spinal needle inlet, and pushed forward, the tip thereof reaches the groove and slides along the groove.

  • Patent number: 8348899
    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.
