  • Patent number: 10342654
    Abstract: A filter with translating hooks is described. The filter can include strut members having first and second struts connected by a connecting portion. A translating hook is disposed adjacent the connecting portion of the strut members, the hook including a first elongate member attached at one end to the first strut and a second elongate member attached at one end to a second strut, the opposite ends of the elongate members connected together to define a tip. The translating hooks are configured to bend toward a central axis of the filter when the filter is in a collapsed configuration for delivery to a blood vessel and recovery from a blood vessel, and away from the central axis of the filter when the filter is in an expanded configuration within a blood vessel such that the hooks engage a vessel wall.

  • Publication number: 20170189213
    Abstract: Apparatuses and methods for coating and/or loading a medical device with a therapeutic agent prior to or during the placement of the medical device within the patient's body. In one variation, the medical device is coated and/or loaded with a therapeutic agent while the device is positioned in a delivery apparatus. In another variation, the delivery apparatus comprises a reservoir for retaining a therapeutic agent. The user may release the therapeutic agent from the reservoir prior to or during the placement of the device to coat and/or load the device with the therapeutic agent.
