    摘要: An electrosurgical medical device for creating thermal welds in engaged tissue that provides general grasping and dissecting functionality. In an exemplary embodiment, at least one jaw of the instrument defines a tissue engagement plane carrying electrosurgical energy delivery means. The jaw assembly, in one mode of operation, can be used for general grasping and dissecting purposes wherein the jaws close in a non-parallel manner so that the distalmost jaw tip only engage tissue with little movement of the actuator lever in the handle of the instrument. In another mode of operation, the jaw assembly closes close in a parallel manner under very high compression to enable tissue welding.

    摘要: A lens is provided that having optical parameters that may be adjusted in-situ, and is particularly useful as an IOL for use in cataract patients that require an adjustment in the optical power of the lens post-implantation. In one embodiment, the lens body carries an array of interior fluid-filled cells in which fluid is controllably moved upon application of energy from an external source to move a fluid media into or out of the cells to thereby alter the lens surface shape.

    摘要: A catheter system for removing occlusive materials from a targeted endoluminal site, such as a vascular graft. The catheter system utilizes an electrical source and a controller to deliver sequences of very small electrical discharges between paired electrodes in a fluid-jet arrangement (i) to cause high fluid flow velocities in the catheter's fluid extraction pathway based on Bernoulli's Law of Pressure Differential, (ii) to create a selected level of turbulent fluid flows within the targeted site to remove occlusive material from the vessel walls and to thereafter suction fluids and entrained embolic particles into the extraction pathway, and (iii) to emulsify any embolic particles having a cross-sectional dimension larger than a couple of hundred micrometers to allows passage of the embolic particles through the elongate catheter to the catheter handle.

    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. The method of the invention may be used in a periodic treatment for the removal of superficial skin layers that enhances the synthesis of dermal collagen aggregates by inducing the body's natural wound healing response. The method of the invention creates more normal dermal architectures in skin with limited depths of skin removal by the series of superficial treatments that may be comparable to the extent of neocollagenesis caused by a deep skin removal treatment (e.g., CO2 laser skin removal).

    摘要: A surgical fixation screw that can be driven with significantly reduced torque thus allowing for theaded fixation bodies to be made substantially of bioabsorbable materials. The novel fixation body, also called an offset helix fixation body, extends along a first (central) axis. The fixation body comprises first and second helically-mating members that mate along a constant-lead helical interface that extends about a second (non-central) axis. The second axis is angularly offset from the first axis of the fixation body from about 1° to 20°. Alternatively, the second axis is parallel to, but laterally offset from, the first axis. Thus, the first and second members of the fixation body can travel helically relative to one another about the helical mating interface between a first insertion configuration and a second anchor configuration. In the insertion configuration, the screw's outer periphery has a first (lesser) transverse sectional dimension to allow reduced torque in helically driving the screw into a space in a bone. After being driven into a space or bore, the first and second members then can be moved helically relative to one another about the helical mating interface to an anchor configuration in which the screws outer periphery is expanded radially outward to provide a second (greater) transverse sectional dimension for securing the fixation body in the space or bore.

    摘要: An electrosurgical medical device and technique for creating thermal welds in the transected margin of engaged tissue. The working end of the invention carries a bi-polar electrode arrangement that provides a novel type of Rf current flow for tissue welding described as an subfascial-to-fascial (or medial-to-surface) bi-polar approach. The working end of the device carries an openable and closable jaw assembly with paired first and second jaws for engaging tissue. The paired jaws have an axial channel for receiving a sliding (blade) member for transecting the captured tissue. The paired jaws carry electrode surfaces having a common polarity so that Rf current will not flow directly between the jaws which engage the surface or fascial tissue layers. The transecting member, when fully extended after transecting the captured tissue, carries an elongate electrode of an opposing polarity that engages the medial or subfascial layers of the tissue. Thus, bi-polar current is directed to flow from the transecting member electrode that engages medial tissue layers to both jaws that engage opposing surface tissue layers to create effective current densities in the medial tissue layers, even when transecting thick tissue volumes or vessels with thick non-uniform fascial layers.

    摘要: A system and technique called magnetoresonant induction of an intrastromal implant that is adapted for corneal re-shaping. The technique is utilized to correct mild to high hyperopia and presbyopia by steepening the anterior corneal curvature in a single treatment, or in periodic treatments over the lifetime of the patient. The system comprises a combination of components including (i) at least one implantable magnetoresonant intrastromal segment, and (ii) an oscillating magnetic field generator together with a dosimetry control system including at least one emitter body adapted for positioning proximate to the patient's eye and intrastromal implant. The system can deliver thermal effects to appropriate stromal lamellae by non-contact inductive heating of the implant which in turn contracts or compresses stromal collagen fibrils into a circumferenitial cinch about an anterior layer of the cornea and steepens the anterior corneal curvature. A dosimetry control system controls the power level and duration of exposure of the oscillating magnetic field(s) and may be combined with intraoperative corneal topography. The system can be adapted for non-contact energy delivery to selected locations in other body structures in the interior of a patient's body.

    摘要: An Rf energy applicator with a working end that carries a bi-polar Rf electrode system for creating a Rf-tissue interaction or ionothermal effect in subsurface tissue (a first ionothermal system) which effect is focused by concurrent actuation of a photonic tissue-sensitizing system or photoconductance system (a second ionothermal system). The photonic energy system is adapted to create a "lens electrode" in subsurface tissue that enhances the targeted tissue's conductance of Rf current which serves as a means of focusing Rf ionothermal effects at a subsurface level. A dosimetry control system is provided that controls the dose and timing of Rf energy delivery as well as the dosimetry of photonic energy delivery. The ionothermal applicator has a handle portion coupled a tubular extending member. The distal termination of the probe has at least one pair of opposing conductive electrodes in a spaced relationship around a perimeter of the distal termination of the extending member. A remote Rf source (or generator) is connected to the device for delivering bi-polar Rf energy to the paired electrodes. An optical fiber (or fiber optic bundle) is provided in a central channel of the extending member which is capable of delivering a photonic (light) beam from a light source, such as a pulsed laser (or continuous wave (CW) diode laser).
