  • Patent number: 5630824
    Abstract: A suture locking button is described. The device includes a base element with a first axial passage for receiving at least one, and preferably two, suture filaments that is attached via a frangible membrane to a locking dement. The locking dement is adapted for movement from a first position, where the locking element extends outwardly from the base dement, to a second position, where the locking element is disposed within the base element by disrupting the frangible membrane to trap the suture filament(s) within the first axial passage between the locking element and the base element. The locking element may have a flange integral with its proximal end that effectively prevents the base element from backing out of the tissue in a direction proximal to the tissue. The invention also pertains to the combination of a suture and a device for securing the suture to a tissue. A method for securing tissue by way of a suture is also included within the scope of the invention.

  • Patent number: 5468239
    Abstract: Novel apparatus and methods for a circumferential laser and methods for using a circumferential burning laser are disclosed. The circumferential burning laser comprises a conical surface at the distal end of a probe of the laser which is coated with a highly reflective material such as gold. The conical, reflective surface is designed so as to direct the laser light which is emitted through the interior metal lumen of the laser probe so that the laser light is redirected perpendicular to the longitudinal axis of the laser probe. This is in contradistinction to the typical laser probe wherein the laser light is directed longitudinally through the end of the laser probe. The laser light is provided by a carbon dioxide laser which is attached at the proximal end of the laser probe.The present invention also comprises methods for using a circumferential burning laser. The methods for using a circumferential burning laser involve placing the above-described laser probe in position relative to a target site.

  • Patent number: 5460427
    Abstract: A seat assembly for a vehicle which includes a seat, a seat back, and mounting means mounting the seat for movement in fore and aft directions in the vehicle along an upwardly concaved arcuate path. The arcuate path has a radius of curvature which is sufficiently large to timely move in front of and to contain the person's buttocks, to significantly slow the rate of deceleration of the person seated on said seat, and being sufficiently small to convert a portion of the linear momentum of the person's buttocks to angular momentum thus maintaining frictional contact of the person's buttocks with the seat during stopping at a high rate of deceleration. A seat assembly which includes a lower lumbar support member that is coupled from movement in response to pelvic tilting movement of the seat also is shown.

  • Patent number: 5458596
    Abstract: An apparatus and method are provided for control contraction of tissue that includes collagen fibers. The apparatus includes a handpiece, and an electrode with an electrode proximal end associated with the handpiece. A distal end of the electrode has a geometry that delivers a controlled amount of energy to the tissue for a desired contraction of the collagen fibers. This is achieved while dissociation and breakdown of the collagen fibers is minimized. The handpiece, with electrode, is adapted to be introduced through an operating cannula in percutaneous applications. Additionally, an operating cannula may be included in the apparatus and be attached to the handpiece. The apparatus and method provides for a desired level of contraction of collagen soft tissue without dissociation or breakdown of collagen fibers.

  • Patent number: 5458617
    Abstract: For applying traction to an arm or a leg, an elongated body of elastic fabric is provided, which has a plurality of evenly distributed pockets that are elongated transversally of the body. Thin lead strips fit in the pockets as stiffeners. Complementary hook and loop fasteners secure the device around the girth of the arm or leg, so that all of the limb is surrounded by stiffener strips. The inner face of the elastic fabric is provided with a layer of anti-slip material, such as foam rubber, which extends beyond the elastic fabric, both lengthwise and widthwise, of the device. By preference, the device is arcuate in plan and the pockets and stiffener strips correspondingly trapezoidally shaped, when intended to fit around the tapering part of a limb.

  • Patent number: 5458595
    Abstract: An improved vaginal speculum for photodynamic therapy of intraepithelial tissue and in particular vaginal, cervical and vulvar neoplasia utilizes a precisely and accurately positionable optic fiber through which a predetermined dose of light in the range of 620 to 700 nanometers is delivered over a controlled area which has been previously treated with photodynamic therapeutic substances. In particular, the neoplastic area has been treated with hematoporphyrin derivatives and other photosensitizers which are selectively taken into the cancerous tissue. Exposure to the appropriate wavelength laser light photoactivates the absorbed hematoporphyrins causing the release of singlet oxygen which internally oxidizes and ultimately causes cell death.

  • Patent number: 5451230
    Abstract: An instrument to facilitate nuclear disassembly during cataract surgery includes a proximal handle, a shaft portion axially aligned with the proximal handle, an intermediate portion constructed to traverse the cortex of the eye, and a hook-form distal end. An inner region of the hook-form has a leading edge defined by diverging surfaces. The diverging surfaces lie at an acute splitting angle to one another selected to have a wedging effect when the leading edge is drawn along a cleavage plane of the nucleus. The diverging surfaces define a relatively bulky back portion that imparts desired stiffness to the leading edge. The hook-form is shaped to facilitate maintaining contact with the nucleus while the leading edge is drawn along the cleavage plane. A method of performing nuclear disassembly during cataract surgery utilizing the instrument is also described.

  • Patent number: 5451222
    Abstract: A smoke evacuation system is provided for attachment to a surgical desiccator, the surgical desiccator including a desiccator body forming a handle and a cauterizing tip for searing tissue to reduce bleeding. The smoke evacuation system includes a section of tube connected to a suction unit, a front retainer and a rear retainer for holding the tube to the body in a position such that the tube and the desiccator body can be cradled in a surgeon's hand, and a suction tip attachable to the front retainer in a non-interfering position proximate the cauterizing tip. The front retainer defines a passageway connecting the suction tip to the section of tube such that smoke, odors and biological contaminants generated by the cauterizing tip can be efficiently suctioned away through the suction tip, the retainer and the tube by the suction unit.
