  • Publication number: 20150105659
    Abstract: An energy delivery system for delivering electrical energy to tissue, includes an elongate catheter member defining a longitudinal axis and dimensioned for passage within a body vessel and an expandable treatment member mounted to the catheter member. The treatment member includes an inflatable element adapted to transition between an initial condition and an at least partially expanded condition upon introduction of an anesthetic solution within the inflatable element, an electrode for delivering electrical energy to at least the nerve tissue associated with the body vessel to cause at least partial denervation thereof and at least one aperture dimensioned to permit passage of the anesthetic solution from the inflatable element to contact the body vessel whereby the solution at least enters the body vessel to at least partially anesthetize the nerve tissue therewithin. The electrode may be mounted to at least the inflatable element of the treatment member and may be generally helical.

  • Patent number: 8992608
    Abstract: The present invention provides methods and apparatus for endovascularly replacing a patient's heart valve. The apparatus includes a replacement valve and an expandable anchor configured for endovascular delivery to a vicinity of the patient's heart valve. In some embodiments, the replacement valve is adapted to wrap about the anchor, for example, by everting during endovascular deployment. In some embodiments, the replacement valve is not connected to expandable portions of the anchor. In some embodiments, the anchor is configured for active foreshortening during endovascular deployment. In some embodiments, the anchor includes expandable lip and skirt regions for engaging the patient's heart valve during deployment.

  • Publication number: 20150073540
    Abstract: The invention includes methods of and apparatus for endovascularly replacing a heart valve of a patient. One aspect of the invention provides a method including the steps of endovascularly delivering a replacement valve and an expandable anchor to a vicinity of the heart valve in an unexpanded configuration; and applying an external non-hydraulically expanding or non-pneumatically expanding actuation force on the anchor to change the shape of the anchor, such as by applying proximally and/or distally directed force on the anchor using a releasable deployment tool to expand and contract the anchor or parts of the anchor. Another aspect of the invention provides an apparatus including a replacement valve; an anchor; and a deployment tool comprising a plurality of anchor actuation elements adapted to apply a non-hydraulically expanding or non-pneumatically expanding actuation force on the anchor to reshape the anchor.

  • Patent number: 8840601
    Abstract: Disrupting tissue and devices and systems for disrupting tissue. The disclosure describes ways to deliver moieties to a target tissue, where the target tissue in general is not at the point of introduction, in such a way that minimal damage is produced in the tissue at the point of introduction. In some embodiments this is accomplished by jetting fluid at high velocity into the target tissue. The disclosure further describes novel agents deliverable in such systems for use in remodeling tissues. Some of these agents comprise a liquid while others do not. Additionally, although not specifically described in detail much of the disclosure may additionally be used in the delivery of therapeutic drugs.

  • Publication number: 20140228949
    Abstract: An accommodating intraocular lens comprises a first lens component, a second lens component, and an adhesive between portions of the two lens components. The cured adhesive bonds the lens components to form a fluid chamber. The lens components are bonded to one another along a seam which extends circumferentially along at least a portion of the lens components. The lens components may comprise the same polymer material. The cured adhesive also comprises the polymer or a prepolymer of the polymer to provide increased strength. The polymer is hydratable such that the lens components and the cured adhesive therebetween can swell together to inhibit stresses between the lens components and the cured adhesive.
