    摘要: An instrument for thermally-mediated therapies in targeted tissue volumes or for volumetric removal of tissue. In one embodiment, the instrument has an interior chamber that includes a diffuser structure for diffusing a biocompatible conductive fluid that is introduced under high pressure. The interior chamber further includes surfaces of opposing polarity electrodes for vaporizing the small cross-section diffused fluid flows created within a diffuser structure. In one embodiment, the diffuser structure includes a negative temperature coefficient of resistance material between the opposing polarity surfaces. The NTCR structure can self-adjust the lengths of current paths between the opposing polarities to insure complete vaporization of the volume of flow of conductive fluid. The non-ionized vapor phase media is ejected from a working surface of the instrument and a controlled vapor-to-liquid phase change in an interface with tissue applies thermal energy substantially equal to the heat of vaporization to ablate tissue. In another embodiment, the instrument provides voltage means for converting the non-ionized vapor phase media into an ionized media or plasma for applying energy to body structure.

    摘要: An instrument and technique for the removal of epidermal layers in a controlled manner utilizing a hand-held instrument with a working end that (i) a vacuum aspiration system, (ii) a source for delivery of a sterile fluids or pharmacological agents to the skin; and (iii) a skin interface surface in the working end that has specially shape structure for abrading surface layers of the patient's epidermis as the working end is moved over the patient's skin while at the same time causing rapid penetration of the fluids into the skin for therapeutic purposes. Movement of the working end across the skin causes abrasion of the surface layers in a path over the patient's skin.

    摘要: A lens for correcting human vision, for example an IOL, contact lens or corneal inlay or onlay, that carries and interior phase or layer comprising a pattern of individual transparent adaptive displacement structures. In the exemplary embodiments, the displacement structures are actuated by shape change polymer that adjusts a shape or other parameter in response to applied energy that in turn displaces a fluid media within the lens that actuates a flexible lens surface. The adaptive optic means of the invention can be used to create highly localized surface corrections in the lens to correct higher order aberrations—which types of surfaces cannot be fabricated into and IOL and then implanted. The system of displacement structures also can provide spherical corrections in the lens.

    摘要: This invention relates to surgical instruments for applying energy to tissue. In one embodiment, an elongated introducer has a handle portion that includes an interior chamber that is supplied with a biocompatible liquid under pressure. An energy source causes a liquid-to-vapor phase change within the interior chamber and ejects a flow of vapor media from the working end of the introducer. The flow of vapor is controlled by a computer controller to cause a selected pressure, a selected volume of vapor, and an optional aspiration of vapor condensate. Contemporaneous with tissue contact, the vapor undergoes a vapor-to-liquid phase transition which delivers large amount of energy to the targeted tissue. In one embodiment, the system is configured for volumetric removal of tissue by means of high velocity ejection of a vapor media from a first vapor port proximate to soft tissue wherein the vapor-to-liquid phase change of the media applies energy to the tissue. The system provides a second port coupled to a suction source that cooperates with the first vapor port to suction tissue debris from the targeted site.
