  • 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.

  • Patent number: 8992442
    Abstract: The invention relates to a device for taking a liquid bone marrow sample (aspiration) and a solid bone sample (biopsy) in the same procedure, which can thus replace specialized needles for taking bone marrow and needles exclusively used for taking bone biopsies. The device for taking liquid bone marrow samples and a solid bone sample has a simple mechanism that uses two grooved clamps, it is easy to disassemble for sterilization and its handle is designed to perform the puncture easily. The needle of the device is hollow, and within it a guide is placed with two sections of different diameters. The guide makes it possible to open up the empty needle channel to allow the bone marrow liquid to flow and be extracted, and also to close the channel to be able to penetrate the tissue. The purpose of this invention is to combine the procedures of bone marrow aspiration and bone biopsy, thus reducing the patient's discomfort and the time needed for the procedure.

    Abstract: An object of the invention is to provide a method and apparatus for the delivery of polynucleotide vaccines into mammalian skin cells to increase T cell response and to reduce pain and discomfort due to long electric waveform application and due to muscle contractions. The method for the delivery of polynucleotide vaccines into mammalian skin cells includes the steps of: (a.) administering a polynucleotide vaccine into the skin at an administration site, (b.) applying a needle electrode to the skin in the vicinity to the administration site, and (c.) applying a sequence of at least three single, operator-controlled, independently programmed, narrow interval electrical waveforms, which have pulse intervals that are less than 100 milliseconds, to deliver the polynucleotide vaccine into the skin cells by electroporation.

  • Publication number: 20150065946
    Abstract: The present inventors have shown that electroporation with calcium ions are efficient on cutaneous and subcutaneous nodules. In particular the present inventors here disclose that a solution comprising calcium ions (Ca2+) with a concentration of at least 0.1 M is extremely useful in a method of treating a neoplasm, such as cancer with means for causing transient permeabilisation of the cell membranes of at least part of the neoplasm before, during and/or after administration of said solution, wherein said solution is administered with a ratio of 0.2 to 0.8 of the volume of said part of the neoplasm.

  • 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: 8915892
    Abstract: Extracorporeal blood treatment methods are usually performed with anticoagulation of the blood. In regional anticoagulation with citrate, sometimes a blood clot is observed in the extracorporeal circulation at the point of addition of the calcium substitution solution. In such a case, the treatment must be interrupted. To prevent such an interruption, the point of addition is configured as a T-piece having a spiral structure for generating turbulence.

  • Patent number: 8911426
    Abstract: An implantable drug delivery device that uses multiple reservoir elements to contain and release doses of active pharmaceutical ingredients. The device includes a first shell element, which has a first enclosed cavity volume and forms a low-permeability barrier. The first shell element is configured to absorb light irradiation from a laser source, the laser irradiation causing a breach in the first shell element. A first active pharmaceutical ingredient is contained in the first enclosed cavity volume and is released when the first shell element is breached. The device also includes a second shell element, which has a second enclosed cavity volume and also forms a low-permeability barrier. A second active pharmaceutical ingredient is contained in the second enclosed cavity volume. The device also includes an envelope element containing the first and second shell elements.
