  • Patent number: 9848870
    Abstract: A coupling system includes an applicator tool and an attachment ring mounted on the applicator tool. Clips are contained within the applicator tool and are deployed through the attachment ring in order to anchor the attachment ring to biological tissue. When deployed, tips of the clips follow a curved trajectory through an annular cuff of the attachment ring and through the underlying tissue. The tips loop back out of the tissue and to a location where they are later trapped or clamped by the attachment ring. While the tips are trapped or clamped, the applicator tool cinches the clips by pulling rear segments of the clips. Thereafter, the applicator tool disconnects from the attachment ring which remains anchored to the tissue and serves as a coupling for a cannula. The cannula can have movable lock members that secure it to the attachment ring.

  • Patent number: 9089395
    Abstract: Generally described herein are apparatus, systems and methods related to a pre-loaded septum insertable in an access port housing for increasing the control of the compression within the septum and the interference between the septum and the housing. For example, a pair of washers having mating portions may be positioned on respective sides of a rubber septum and bent such that the mating portions of one of the washer are interlocked with the mating portions of the other washer, the interlocked portions forming a tight ring about the septum and generating lateral compression on the septum, thereby “loading” the septum. In addition, fluid seals made of a rubber material with lower durometer than the rubber septum may be used at the interface between the rubber septum and the housing to enhance the fluid sealing functionality while promoting the self-sealing features of the rubber septum.

  • Patent number: 9039680
    Abstract: Implantable devices and methods for delivering drugs and other substances to locations within the body of a human or animal subject to treat or diagnose sinusitis and a variety of other disorders. The invention includes implantable substance delivery devices that comprise reservoirs and barriers that control the rate at which substances pass out of the reservoirs. The delivery devices may be advanced into the body using guidewires, catheters, ports, introducers and other access apparatus. In some embodiments the delivery devices may be loaded with one or more desired substance before their introduction into the body. In other embodiments the delivery devices are loaded and/or reloaded with a desired substance after the delivery device has been introduced into the body.

    Abstract: An implantable medical device for performing therapy or monitoring a physiological condition. The device includes components for connecting the device to a trunk line. These components connect the device to the trunk line in such way that the components move over the trunk line. Internal to these components are conductors, including a coil, that are arranged to complementary inductively exchange signals with conductors internal to the trunk line. As a result of this inductive signal exchange the implantable medical device at least one of: receives power signals; receives signals that regulate the operation of the device; or transmits signal representative of the physiological state monitored by the device.
