  • Patent number: 10159601
    Abstract: A method and delivery system are disclosed for creating an aqueous flow pathway in the trabecular meshwork, juxtacanalicular trabecular meshwork and Schlemm's canal of an eye for reducing elevated intraocular pressure. Pulsed laser radiation is delivered from the distal end of a fiber-optic probe sufficient to cause photoablation of selected portions of the trabecular meshwork, the juxtacanalicular trabecular meshwork and an inner wall of Schlemm's canal in the target site. The fiber-optic probe may be advanced so as to create an aperture in the inner wall of Schlemm's canal in which fluid from the anterior chamber of the eye flows. The method and delivery system may further be used on any tissue types in the body.

    Abstract: A control device for an ophthalmic surgical system includes a flow determination device for determining an actual value of fluid flow in an aspiration line. The aspiration line is coupled to a handpiece for phacoemulsification of an eye lens and an occlusion determination device determines whether there is an occlusion because of a particle of the eye lens at a suction opening of the aspiration line. An evaluation unit establishes a hardness of the particle in dependence on the determined actual value of the fluid flow in the aspiration line should the occlusion determination device have determined that an occlusion is present, and, dependent on the hardness, determines a first value of ultrasound energy, which can be supplied to the handpiece by an energy source. A control unit actuates the energy source, during the occlusion, so that it outputs the determined first value of the ultrasound energy.

    Abstract: The present disclosure relates in general to an apparatus and method for priming a liquid or surgical cassette. In one embodiment, an infusion system within the liquid cassette is primed using a forward flow of a liquid and a backward flow of the liquid. The forward flow of the liquid creates a first volume of liquid stored within an infusion conduit, which is connected to an infusion chamber via a first valve. The infusion conduit has an infusion port exposed to a non-liquid environment having a first pressure. A second pressure is created in the infusion chamber that is lower than the first pressure. Opening the first valve causes a second volume of liquid within the infusion conduit to flow over the first valve and towards the infusion chamber. The second volume of liquid is less than or equal to the first volume of liquid.

  • Patent number: 8992462
    Abstract: Systems and methods for providing multiple pass continuous flow dialysis therapy are provided. The present invention includes a fluid circuit connected to a patient via a catheter thereby defining a fluid loop along which a therapy fluid including a dialysate can be continuously circulated into, through and out of a peritoneal cavity of a patient to remove a therapeutically effective amount of excess water and solutes including uremic toxins. The feed rate and discharge rate of therapy fluid into the fluid loop can be controllably regulated in proportion to the circulation rate of fluid in the fluid loop such that the therapy fluid can pass a multiple number of times along the fluid loop prior to discharge.

  • Patent number: 8992460
    Abstract: To treat body surfaces, such as the sinuses, which are coated with biofilms, the surface is irrigated and suctioned with a fluid which may contain a biocide or other chemical agent for disrupting the biofilm while ultrasonic energy is applied to either the fluid barrier formed over the biofilm or a body surface proximal to the biofilm. Action of the fluid enhanced by the ultrasonic energy tends to remove sections of biofilm which are suctioned out of the site. An electrical field may also be applied to the biofilm to enhance the disruptive action. Apparatus for practicing this method to treat chronic rhinosinusitis comprises an elongated tube adapted to be inserted into sinus cavities through the nose or mouth. The tube includes a first lumen which feeds an irrigating fluid containing biocides and/or biofilm-disruptive chemicals to the treatment site and a second lumen which suctions fluid from the site.

  • Publication number: 20150080787
    Abstract: An apparatus for cleansing wounds in which irrigant fluid from a reservoir connected to a conformable wound dressing and wound exudate from the dressing are recirculated by a device for moving fluid through a flow path which passes through the dressing and a means for fluid cleansing and back to the dressing. The cleansing means (which may be a single-phase, e.g. microfiltration, system or a two-phase, e.g. dialytic system) removes materials deleterious to wound healing, and the cleansed fluid, still containing mate rials that are beneficial in promoting wound healing, is returned to the wound bed. The dressing and a method of treatment using the apparatus.

  • Patent number: 8951221
    Abstract: The invention relates to a method and device for the treatment of glaucoma, though insertion of an implant into the lumen of the Schlemm's canal to realize proper drainage of the aqueous humor, which implant is brought into its position in the Schlemm's canal by means of a catheter having a distal and a proximate portion and provided with a number of pores through which a gaseous or fluid medium which comes from a pressure source can emerge during insertion of the catheter carrying the implant into the Schlemm's canal, and while the catheter is being inserted into the Schlemm's canal the gaseous or fluid medium is released under pressure thereby expanding the Schlemm's canal and the implant and upon releasing the implant at its determined location, the catheter can be withdrawn from the Schlemm's canal.

  • Patent number: 8945038
    Abstract: A surgical technique and device wherein an indwelling tube is placed in the eye of a patient having glaucoma. The tube diverts aqueous humor from the anterior chamber to the suprachoroidal space from which it is removed by blood flowing in the choroidal and uveal tissues. This decreases the intraocular pressure.

  • Patent number: 8926587
    Abstract: The pneumatic system for intussusception treatment, i.e., invagination of a segment of the intestine into an adjacent segment, includes a pressurized gas supply connected to a series of filters, valves, regulators, and sensors connected to a rectal insertion tube to introduce gas at moderate pressure into the intestine of the patient. A computerized control and monitoring subsystem is included. The system preferably includes a heating system to warm the gas as desired. The system also preferably includes an exhaust portion to relieve internal intestinal pressure as required or desired. The exhaust portion of the system preferably includes a filter to absorb undesirable fecal odors that accompany the exhausted gas. At least the rectal insertion tube and the odor filter may be separable from the remainder of the system for convenient disposal. An alarm may be provided to alert the doctor or medical professional of conditions other than normal.

  • Patent number: 8926549
    Abstract: A handle for a medical instrument having a handle housing that can be closed by a cover and having at least one drainage or irrigation hose in the handle housing that can be connected to a hose connection support. To create a handle that is of a simple construction and ensures a reliable fluid-proof insulated connection of the at least one hose and the hose connection support while protecting a material of the at least one hose, it is proposed that each drainage or irrigation hose should be connectable by an adaptor to the hose connection support and that the adaptor upon closing the handle housing can be pressed against the hose connection support by a stop positioned on the cover or on a base portion of the handle housing.

    Abstract: An apparatus 100 for use in tube feeding comprises a cylindrical body 110 provided with a first opening 120 and a second opening 130 connected by a flow channel 140. The body 110 comprises reagent 111, for determining a characteristic of fluid disposed in the body and a transparent window 112 through which the reagent 111 is visible. In use, a first end of an internal feeding tube releasably engages with the first opening 120. The second, distal end of said feeding tube is disposed inside a patient to be fed. A second feeding tube engages with the second opening 130. The second feeding tube connects the apparatus 100 to a bi-directional pump operable: to pump internal fluid from a reservoir, through the apparatus and into the internal feeding tube; and to pump fluid from the patient into the body 110 of the apparatus 100. This allows a user to pump fluid from the patient into the body 110 of the apparatus 100 to react with the reagent 111.
