  • Patent number: 10856979
    Abstract: A prosthesis for implantation at a native semilunar valve includes a prosthetic distal valve, which includes a pliant material configured to collapse inwardly towards a longitudinal axis of the prosthesis during diastole, and to open outwardly during systole, and a distal fixation member configured to be positioned in a downstream artery of the subject. The apparatus also includes a proximal fixation member coupled to the distal fixation member, and configured to be positioned at least partially on a ventricular side of the native semilunar valve. The proximal fixation member is shaped so as to define a lattice that is shaped so as to define an intermediary portion that is coupled to the pliant material of the valve and diverges outwardly from the longitudinal axis, and a distal portion that is distal to the intermediary portion and diverges outwardly from the intermediary portion of the lattice. Other embodiments are also described.

  • Patent number: 10765560
    Abstract: An instrument comprises a handpiece, a boss member, a cylindraceous cam body, a linearly movable member, a cam follower, and a braking member. The cam body is rotatably supported in the handpiece and includes an exterior cam feature. The cam follower couples the linearly movable member with the cam feature of the cam body. The cam feature and the cam follower cooperatively drive the linearly movable member linearly in response to rotation of the cam body within the handpiece. The braking member extends about at least a portion of the exterior of the cam body and is positioned to progressively engage the boss member as the cam body rotates within the handpiece. The braking member and the boss member thus cooperate to provide gradual braking of the cam body. The instrument is operable to deploy a pressure equalization tube in the tympanic membrane of a patient.

    Abstract: The purpose of the “Dissolvable on-command Implant” is to act as a pressure equalizer tube in the eardrum, which has the unique characteristic that the tube can be dissolved with a specially formulated drop solution on-command. This tube can have various shapes and sizes, although the tube is usually a cylindrical tube with a hollow center, which maintains a ventilatory port for the middle ear space. With this design, the ear tube promotes drainage of middle ear fluid, lets air enter the middle ear, and allows for instillation of antibiotic drops.

  • Publication number: 20120253357
    Abstract: Provided is an introducer for use with otolaryngological devices such as Eustachian tube stents. The introducer includes a guide, a stopper, an engager, and a release mechanism. An otolaryngological device having a first surface and a second surface that is nonparallel to the first surface may be loaded on the introducer by frictionally engaging the first surface of the device to a distal terminus of the engager. The device may be unloaded from the introducer by actuating the release mechanism. Upon actuation, the release mechanism slides the distal terminus of the engager toward the guide while the stopper abuts the second surface of the device. As a result, the relative motion between the engager and the stopper slides the device off the engager. Also provided are kits that include the introducer and methods for using the introducer.

  • Publication number: 20120245593
    Abstract: A kit is provided comprising a stent, an introducer and a bender. The stent is constructed for insertion into a Eustachian tube of a human. The stent comprises a member having a preinsertion form that includes opposing exterior surfaces, means for immobilizing the stent within the Eustachian tube, and means for providing fluid communication between the opposing surfaces to effect pressure equilibration therebetween. The introducer includes a guide, an engager, and a sliding mechanism. A Eustachian tube method is also provided. The method involves using the above-described kit.

  • Patent number: 8265765
    Abstract: The present invention provides for fitting a multimodal hearing system to a recipient. Such fitting may include determining a desired perception for an input signal, receiving a measurement of a perception evoked by applying to the recipient one or more stimulation signals that correspond to the input signal, wherein the one or more stimulation signals applied using two or more stimulation modes, and each stimulation signal is determined using stimulus mode weighting, and adjusting one or more of the stimulus mode weightings based on the difference between the measured evoked perception and the desired perception. A multimodal hearing system is able to stimulate using an acoustic, electrical, mechanical mode and/or photo effect mode.

  • Patent number: 8197552
    Abstract: Devices are provided for insertion into a Eustachian tube of an animal, e.g., a human being. The devices include an insertable member. The member has opposing surfaces and is formed at least in part from a biocompatible material that is degradable. The device may comprise a hole that is effective to provide sufficient fluid communication between the opposing surfaces of the insertable member to effect pressure equilibration therebetween. The device is able to be immobilized within the Eustachian tube for a predetermined period. Also provided are kits that include the device and methods for inserting the device into a Eustachian tube.

  • Patent number: 8075511
    Abstract: Systems and methods for treating ocular disorders are disclosed. One system has an implant and a delivery device. The implant has inlet and outlet portions, a lumen extending therebetween and communicating with inlet and outlet ports. The implant is sized so that in use aqueous humor flows from an anterior chamber of an eye through the implant and into a uveal scleral outflow path of the eye. The delivery device is configured to advance the implant from within the anterior chamber, with the outlet portion leading the inlet portion, to a location where the outlet and inlet ports respectively communicate with the uveal scleral outflow path and the anterior chamber. One method involves advancing an implant from within the anterior chamber, and draining fluid from therein such that fluid flows into an implant inlet port and out through an implant outlet port and into the uveal scleral outflow path.
