  • Publication number: 20220313269
    Abstract: A distal portion (16) of an elongated body (12) is configured to mate with a distal portion (20) of an interface member (18) mechanically connected to an embolization device (22). The embolization device (22) is additionally attached to the elongated body (12). The elongated body distal portion (16) and the interface member proximal portion (19) may collectively define a protrusion and a recess configured to receive the protrusion to provide the mating. The elongated body (12), interface member (18), and embolization device (22) may be configured for delivery to a vasculature target site, and manipulation of the deployed embolization device (22) may be facilitated by the mating between the elongated body (12) and the interface member (18).

    Abstract: A device for mixing a medical agent and associated systems and methods are disclosed herein. In some embodiments, the device comprises (i) a housing defining a chamber configured to contain a fluid and having a longitudinal axis, (ii) a plunger assembly at least partially disposed within the chamber, the plunger assembly comprising a plunger and a stirring member extending along the longitudinal axis, and (iii) an actuating assembly operably coupled to the stirring member. The actuating assembly can have an active state in which the actuating assembly causes a distal end portion of the stirring member to rotate at a predetermined speed.

  • Publication number: 20190298387
    Abstract: An implant for treatment of a vascular space can form open loops and closed loops in separate cycles to provide balanced stiffness and flexibility. Such an implant provides both stability for retention within the vascular space and conformability for mitigating forces on the vasculature. Such a configuration can also provide proper coverage over an opening to a vascular space into which the implant is delivered, for reducing or eliminating flow into or out of the body cavity and promoting occlusion of the vascular space.

  • Patent number: 10418756
    Abstract: To avoid the disadvantages of additionally required space, unwanted crosstalk and deterioration in transmission properties that are concomitant with a separate transformer, a plug connector is proposed, comprising: a plug base with terminal contacts for external contacting of the plug connector, base-side connection contacts, and a transformer unit for galvanic separation in a conductive path between the terminal contacts and the base-side connection contacts and a plug body with plug contacts, the plug base and the plug body enclosing a contact element for connecting the base-side connection contacts to the plug contacts and the contact element being planar in a plane perpendicular to a plug-in direction of the plug body. A shielding element for the plug connector is also proposed.

  • Publication number: 20170346717
    Abstract: The present disclosure provides a method and apparatus for learning a MAC address of a TRILL network. The method comprises: learning, by a routing bridge connected to an end system, a MAC address of the end system; encapsulating the MAC address in a link-state packet, sending the link-state packet to a neighbor routing bridge; after the neighbor routing bridge receives the link-state packet, judging whether the MAC address in the link-state packet is locally present; if not, learning the MAC address in the link-state packet and setting a local confidence to a confidence of the MAC address in the link-state packet; if yes, updating a confidence of a local MAC address to the confidence of the MAC address in the link-state packet, increasing the confidence of the MAC address in the link-state packet by 1, and sending the link-state packet to all neighbor routing bridges except a receiving end.

  • Patent number: 9219333
    Abstract: An electrical connector for contacting a mating connector is proposed which has a locking device and includes a locking mechanism by means of a tiltable locking latch. The spring-loaded unlocking mechanism is triggered by pulling on a pull tab and constitutes a secure locking connection between the electrical connector and the mating connector.

  • Patent number: 9130308
    Abstract: The invention proposes an electrical plug-type connector for making contact with a mating plug-type connector, said plug-type connector having a displaceable locking and unlocking apparatus, which exerts a constant pressure on the apparatus by means of a double-sided torsion spring in such a way that the plug-type connector is forcibly locked when contact is made between said plug-type connector and the mating plug. In this case, the pressure exerted by the torsion spring legs is transferred to two axially displaceable sliding posts, which are again part of the unlocking apparatus. Furthermore, the unlocking apparatus has two sliding arms, which can be displaced in a tongue-and-groove guide, at least in regions, within corresponding recesses and flush with respect to the side faces of the plug-type connector housing.

  • Patent number: 8926352
    Abstract: To compensate the lateral offset of an opposing plug, a contact element for a plug-in connector socket has particularly large tolerances. For this purpose, the contact element is embodied in two pieces, a contact spring element for making electrical contact with the opposing plug and a securing element in which the contact spring element is mounted so as to be rotatable about a rotational axis. In contrast to a case in which tolerances depend on deformation of a spring element, by virtue of rotation of the contact spring element no forces act on the soldering points with which the securing element is soldered to a printed circuit board. The contact element is particularly suitable for soldering according to SMT.

  • Patent number: 8758068
    Abstract: A contact spring has two contact arms which are connected at their respective source areas via a bridge and are intended for clamping in and making contact with the mating contact which is to be inserted in an insertion direction. The contact arms are arranged essentially pointing in the opposite direction to the insertion direction of the mating contact running toward one another, and curving away from one another on their free standing end areas. The contact spring has at least one first solder connection which is integrally formed directly on the bridge and faces in the opposite direction to the insertion direction of the mating contact.
