  • Patent number: 6004261
    Abstract: An uncured or partially cured, collagen-based material is delivered to a selected site in a blood vessel and is crosslinked in the blood vessel by laser energy or other suitable energy to form an endovascular stent. The collagen-based material can be delivered to the blood vessel as a coating on an inflatable balloon mounted on the distal end of a catheter. The collagen-based material can also be delivered to the blood vessel in liquid form. The liquid collagen-based material is forced through a porous balloon to form either an imperforate tubular configuration or a tubular mesh configuration. The collagen-based material is preferably crosslinked by laser radiation carried through an optical fiber to a diffusing tip located within the balloon.

  • Patent number: 5868776
    Abstract: An overlay dual balloon catheter. Two balloons composed of differing materials are employed, the balloons being disposed so as to overlap one another but not being bonded to one another, so that adjacent surfaces of the two balloons are permitted to move relative to one another, to provide improved surface and structural characteristics in a balloon unit. Preferably, an outer balloon, disposed on the exterior of the catheter is composed of latex, silicone, or a thermoplastic elastomer while an inner balloon, disposed underneath the first balloon is composed of a material employed in existing angioplasty balloons such as polyester or polyurethane. The overlay dual balloon catheter may be used in angioplasty, embolectomy and thrombectomy.

  • Patent number: 5865835
    Abstract: A forceps having a closed loop defined by the ends of beveled grasping tips attached to a pair of jaws of locking forceps in a closed position, a series of mating serrations on the jaws ending proximate the loop, and having an hourglass shape when viewed in profile. The forceps reduces slippage of the vagus by a raised bevelled ridge on the closed loop facing inward towards the aperture. The oval-shaped and hourglass profiled aperture defined by the closed loop is shaped and sized to permit a surgeon to firmly grasp the vagus nerve, and to elevate it up and out of the incision area, in order to facilitate the remaining procedure. The preferred aperture opening is defined by the loop having a 3 mm transverse inner diameter and 4 mm longitudinal inner diameter. The hourglass profile allows the vagus nerve to rest in a transverse groove of the tip, defining the constriction found in the hourglass profile.

  • Patent number: 5833707
    Abstract: An apparatus and method for temporarily implanting an intraluminal stent in a body lumen and its subsequent removal. A stent is formed from a thin sheet that has been wound around itself into a generally cylindrical roll. The stent has a deployed configuration with a deployed diameter generally the size of the lumen diameter. The stent has a delivery configuration, formed by winding the stent more tightly than the deployed configuration, with the delivery diameter smaller than the deployed diameter in order to allow low profile delivery into the body lumen. The stent will transform from the delivery configuration to the deployed configuration when exposed to body heat. The stent can be deployed by an intraluminal delivery catheter that secures the stent in its delivery configuration during intraluminal delivery of the stent. The stent can be removed from the body lumen via a removal catheter that coils the stent into a sheath at the end of the removal catheter.

  • Patent number: 5800453
    Abstract: This invention is a surgical instrument and specifically is a device for delivering embolic coils to a selected site within the vasculature or other lumen of a human body via use of a catheter. The invention includes the coils as well. In particular, the device uses embolic coils having a receiving slot on one end of the coil; a catheter control wire or pusher guidewire having a hook which cooperatingly engages the coil's receiving slot is used as a coil pusher to eject the coil at the chosen site. The coils of this invention may also be placed within the lumen with a catheter in a nose-to-tail fashion and pushed into the body lumen. Pushing the coil assembly via the pusher from the distal end of the catheter body uncouples the most distal coil.

  • Patent number: 5797950
    Abstract: An apparatus for releasing congested prostate fluid including a head having a size suitable for fitting in a human rectum and through a sphincter and having a surface suitable for rubbing a prostate gland, and a rod connected to a bottom of the head and extending outwardly therefrom. The rod serves to position the head and guide a movement of the head as the sphincter contracts and relaxes. An abutment surface is affixed to the rod distal the head. The abutment surface serves to contact a perineum area and to push up on the perineum area as the sphincter contracts. The rod is a rigid rod having a generally L-shaped or C-shaped configuration with a radius of curvature such that the head tilts toward the prostate gland as the sphincter contracts and draws the head upwardly. The head has a generally ellipsoidal shape. The head is formed of rubber-like material.

  • Patent number: 5797937
    Abstract: An ophthalmologic knife includes a handle, and a blade having a base portion fixed to the tip of the handle and an incision-forming portion integrally formed with the base portion. The entire portion of the blade or at least part of the incision-forming portion which is inserted into the cornea of an eyeball has an arcuate cross section. By using the ophthalmologic knife, a three-dimensional incision having an arcuate cross section is formed in the cornea or the like. When a three-dimensional object having a cylindrical cross section or the like is inserted into the incision, the convex portion surrounded by the incision is bent toward the inside of the eyeball. This allows smooth insertion of the object.

  • Patent number: 5779713
    Abstract: Diseased tissue is liquefied in the presence of non-diseased tissue by contact with a paddle moving with angular velocity. The edge of the paddle is dull and the angular velocity is sufficient to batter the diseased tissue into a liquid without adversely affecting the structure and function of the non-diseased tissue. The shape of the paddle and the rotational speed can be designed and chosen depending on the consistency of the tissue to be resected, whether hard or soft. Upon liquefaction, the diseased tissue is removed by vacuum aspiration. This instrument therefore gives the neurosurgeon the ability to differentially resect diseased tissue while preserving the surrounding structures intact.
