Patent number: 6149673Abstract: The present invention provides a method and apparatus for controlling the internal body temperature of a patient. According to the present invention, a catheter is inserted through an incision into a large blood vessel of a patient. By selectively heating or cooling a portion of the catheter lying within the blood vessel, heat may be transferred to or from blood flowing within the vessel and the patient's body temperature may thereby be increased or decreased as desired. The invention will find use in treating undesirable conditions of hypothermia and hyperthermia, or for inducing a condition of artificial hypothermia when desired. The method and system further provide for the cooling of initially hypothermic patients whose blood or body temperature has been warmed above the desired target level and the warming of initially hyperthermic patients whose blood or body temperature has been cooled below the desired target temperature.Type: GrantFiled: August 7, 1998Date of Patent: November 21, 2000Assignee: Radiant Medical, Inc.Inventor: Robert Ginsburg

Patent number: 6142969Abstract: Sutureless, implantable fluid shunting devices and associated methods for controlling the pressure of fluids within anatomical spaces or cavities of the body. The device generally comprises a tube having a diffusion barrier (e.g., diffusion chamber) formed on a proximal end thereof. Fluid which flows through the tube will collect within the diffusion chamber and will diffuse outwardly therethrough. However, the presence of the diffusion chamber will prevent microbes, cells or other matter from interfering with or backflowing through the tube. Additionally, the tube may be provided with a pressure-openable aperture through which fluid from the tube may flow into the diffusion chamber. Such pressure-openable aperture will remain closed, until the pressure of fluid within the tube exceeds a predetermined maximum pressure P.sub.MAX.Type: GrantFiled: July 27, 1998Date of Patent: November 7, 2000Assignee: Anamed, Inc.Inventor: Alok Nigam

Patent number: 6142996Abstract: A device and system for creating small (e.g., less than 3 mm and preferably about 1 mm in cross dimension) openings in the anterior lens capsule of a mammalian eye to facilitate insertion of lens reduction/removal device(s) and/or cannulae for injecting flowable lens replacement materials into the lens capsule. The device generally comprises a handpiece having an electrosurgical probe extending forwardly therefrom. The electrosurgical probe incorporates an annular tip electrode which is positionable in contact with the lens capsule, to create the desired less than 3 mm opening therein. The annular electrode tip may be either monopolar or bipolar in design.Type: GrantFiled: July 9, 1999Date of Patent: November 7, 2000Assignee: Optex Ophthalmologics, Inc.Inventors: Soheila Mirhashemi, Michael Mittelstein, John T.

Patent number: 6117149Abstract: A system and method for reducing and removing and ophthalmic lens of a mammalian eye. The system includes a rotary lens-reducing probe device of either straight or curved configuration, the probe device comprising a tubular outer sheath through which a rotatable drive shaft extends. A rotating lens-reducing head member is positioned on the distal end of the drive shaft. The head member is configured and constructed to draw a flow of fluid and lens matter into contact therewith, thereby facilitating complete reduction of the entire lens without requiring significant axial (i.e., longitudinal) movement of the probe within the lens capsule. The distal portion of the tubular sheath is preferably configured to shield a portion of the lens-reducing head, during operation, to avoid inadvertent damage to lens capsule. Also, the distal portion of the sheath may be aimed or positioned to direct the flow of fluid and lens matter created by the rotating head in a preferred flow path within the lens capsule.Type: GrantFiled: February 11, 1999Date of Patent: September 12, 2000Assignee: Optex Ophthalmologics, Inc.Inventors: John T. Sorensen, Michael Mittelstein, Soheila Mirhashemi

Patent number: 5971992Abstract: An apparatus for mounting a radially expandable intraluminal stent or stented graft onto a delivery catheter. The apparatus comprises a hollow housing defining an interior chamber and a fluid port which communicates with the interior chamber. Disposed within the interior chamber of the housing is a collapsible, resilient tubular sleeve which is sized to receive a portion of the delivery catheter having the stent or stented graft positioned thereupon. The sleeve includes an open end which communicates with the exterior of the housing. The pressurization of the interior chamber of the housing via the fluid port facilitates the uniform radial compression of the sleeve, with the depressurization of the housing via the fluid port causing the sleeve to resiliently return to an uncompressed state.Type: GrantFiled: August 14, 1998Date of Patent: October 26, 1999Inventor: Ronald J.
