  • Patent number: 10589445
    Abstract: A method of cleaving off a daughter single crystal substrate from a parent single crystal substrate includes providing a stress-mandrel and the parent a single crystal substrate. The parent single crystal substrate has a major surface and an edge surface that intersects the major surface. The major surface extends along a major surface plane. The stress-mandrel has a stress-mandrel coefficient of thermal expansion that is higher than the parent single crystal coefficient of thermal expansion. The method includes bonding the stress-mandrel to the major surface, and cooling the parent single crystal substrate and the stress-mandrel. The cooling of the parent single crystal substrate bonded to the stress-mandrel provides a thermal stress in the parent single crystal substrate sufficient to cleave the parent single crystal substrate. The cleaving extends substantially along a plane parallel to the plane of the major surface. In one embodiment the cleaved daughter substrate was used to make a photovoltaic cell.

  • Patent number: 10479009
    Abstract: A molded vehicle component (10) having a skin (14) and a lower density core (16) formed by a co-injection molding process. In a first phase, a first material for forming the skin of class A surface material is injected into a mold to partially fill the mold cavity (104). Thereafter, in a second phase, a second material is injected into the same cavity (104) to complete filling of the mold cavity (104). The second material can flow only to portions of the part where the first material is still molten and displaces the molten core of the first phase, pushing it away from co-injection gates until the mold cavity is full. The second material is pre-treated with a chemical blowing agent in order to reduce part weight by foaming the core material. The finished co-injection molded part (10) has one material on all visible class A surfaces (14) and a core (16) that is a different, less dense material.

  • Patent number: 8679110
    Abstract: A catheter includes a plurality of primary leads to deliver energy for ligating a hollow anatomical structure. Each of the primary leads includes an electrode located at the working end of the catheter. Separation is maintained between the primary leads such that each primary lead can individually receive power of selected polarity. The primary leads are constructed to expand outwardly to place the electrodes into apposition with an anatomical structure. High frequency energy can be applied from the leads to create a heating effect in the surrounding tissue of the anatomical structure. The diameter of the hollow anatomical structure is reduced by the heating effect, and the electrodes of the primary leads are moved closer to one another. Where the hollow anatomical structure is a vein, energy is applied until the diameter of the vein is reduced to the point where the vein is occluded. In one embodiment, a secondary lead is surrounded by the primary leads, and extends beyond the primary leads.

  • Patent number: 8267931
    Abstract: A catheter includes a plurality of expandable primary leads to deliver energy to a fallopian tube, a vein such as a hemorrhoid or an esophageal varix, or another hollow anatomical structure requiring ligation or occlusion. Each of the primary leads includes an electrode located at the working end of the catheter. Separation is maintained between the primary leads such that the leads can receive power of selected polarity. The primary leads are constructed to expand outwardly to place the electrodes into apposition with a hollow anatomical structure. High frequency energy can be applied from the leads to create a heating effect in the surrounding tissue of the anatomical structure. The diameter of the hollow anatomical structure is reduced by the heating effect, and the electrodes of the primary leads are moved closer to one another.

  • Patent number: 7976536
    Abstract: A catheter introduces electrodes in a vein for a minimally invasive treatment of venous insufficiency by the application of energy to cause selective heating of the vein. The catheter is positioned within the vein to be treated, and the electrodes on the catheter are moved toward one side of the vein. RF energy is applied in a directional manner from the electrodes at the working end of the catheter to cause localized heating and corresponding shrinkage of the adjacent venous tissue, which may include commissures, leaflets and ostia. Fluoroscopy or ultrasound may be used to detect shrinkage of the vein. After treating one section of the vein, the catheter can be repositioned to place the electrodes to treat different sections of the vein until all desired venous valves are repaired and rendered functionally competent.

  • Patent number: 7967782
    Abstract: A catheter delivers an electrode within a vein for a minimally invasive treatment of varicose veins and venous insufficiency using RF energy. The catheter is introduced into a patient and positioned within the section of the vein to be treated. The electrode radiates high frequency energy towards the vein, and the surrounding venous tissue becomes heated and begins to shrink. The catheter includes a controllable member for limiting the amount of shrinkage of the vein to the diameter of the member. The electrode remains active until there has been sufficient shrinkage of the vein. The extent of shrinkage of the vein may be detected by fluoroscopy. After treating one section of the vein, the catheter and the electrode can be repositioned intraluminally within the vein to treat different sections of the vein until all desired venous sections and valves are repaired and rendered functionally competent.

  • Patent number: 7901402
    Abstract: A catheter includes a first plurality of expandable leads and a second plurality of expandable leads separate and longitudinally spaced-apart from the first plurality to deliver energy to a hollow anatomical structure, such as vein, fallopian tube, hemorrhoid, esophageal varix, to effectively ligate that structure. Each of the leads includes an electrode located at the distal end of the respective electrode lead. Polarizations of the leads may be selected to achieve the power distribution desired. Each electrode lead includes an outward bend such that when a movable sheath is moved out of contact with the leads, they expand outwardly into apposition with an inner wall of the structure to be ligated. High frequency energy can be applied from the leads to create a heating effect in the surrounding tissue of the anatomical structure.

  • Publication number: 20090125009
    Abstract: One embodiment comprises an apparatus for applying energy to a hollow anatomical structure having an inner wall. The apparatus comprises an elongate shaft having a distal end and a proximal end opposite the distal end; and a capacitive treatment element located near the distal end. The capacitive treatment element is sized for insertion into the hollow anatomical structure and placement near the inner wall. The capacitive treatment element is configured to create an electric field that extends at least partially into the inner wall. Other devices and methods for treatment of hollow anatomical structures are disclosed as well.

  • Patent number: 7163546
    Abstract: Apparatuses and methods for removing veins, usually varicose veins, rely on endoluminal capture of a distal end of the vein segment to be removed. In the illustrated embodiments, a shaft having reciprocatable penetrating elements is used to engage and capture the distal end of the vein. After rotating the shaft to pull the distal segment of the vein away from the connecting tissue, the shaft is withdrawn proximally, invaginating the segment back to the point of insertion.
