Patent number: 6312409Abstract: A device (10) for generating a pulsatile fluid drug flow comprises a housing (11) containing an expandable-contractible chamber (12) having an inlet (14) and an outlet (15), a valve (16) associated with the outlet (15) which is actuated by the expansion and contraction of the chamber (12), and means (13, 23) for biasing the chamber (12) to its contracted state. When the inlet (14) is connected to a pressurised fluid drug supply the chamber (12) is expanded by the drug, and this expansion of the chamber (12) actuates the valve (16) to open, thereby allowing release of the drug from the chamber (12), following which the chamber (12) contracts under the influence of the biasing means (13, 23), this contraction in turn actuating the valve (16) to close thereby allowing the chamber (12) to refill. By this mechanism, a constant supply of liquid, such as from an osmotic or elastomeric drug delivery pump, can be converted to a pulsatile flow, which may provide a more suitable delivery of certain drugs.Type: GrantFiled: September 7, 1999Date of Patent: November 6, 2001Assignee: Elan Corporation, PLCInventor: Joseph Gross

Patent number: 6312439Abstract: The present invention provides a new approach to reshaping of the cornea, e.g., for refraction change, using multiple, displaced planar cuts and a custom shaping template. Large refractive change and/or substantial tissue removal can be obtained by a two-cut approach to reshaping of the cornea to a desired shape using a template or applanator. The process begins with a planar template being applied to the cornea. The template includes one or more moveable sections or cams positioned to provide an overall flat contact surface with the cornea. Then, a first cut is made by a water microjet producing a hinged flap. The first cut is parallel to but displaced from the anterior cornea surface in contact with the template. Then the template cam or cams are repositioned to change the shape of the cornea surface in situ in preparation for the second cut. The hinged flap is not moved; it remains in contact with the stromal bed. The second cut is along the same path as the first cut.Type: GrantFiled: January 14, 2000Date of Patent: November 6, 2001Assignee: Medjet, Inc.Inventor: Eugene I. Gordon

Patent number: 6312441Abstract: A powered surgical handpiece (20) designed to actuate cutting accessories (22) such as those used to perform endoscopic surgery. The handpiece includes a housing (24) that contains a motor (26). The motor is within its own housing (46). A motor rotor (88) extends out of the motor housing (46) and engages a gear reduction assembly (76). The gear reduction assembly includes a planetary gear assembly for which the motor rotor (88) is the sun gear. The motor housing (46) is formed to have integral therewith a ring gear (96) that is located around the portion of the motor rotor that extends out of the motor housing. There is a valve (44) for regulating suction flow through the handpiece. The valve sits in a valve bore (110) that is closed at one end. There is also coupling assembly (28) for releasably holding the cutting accessory to the housing so that the cutting accessory engages with the gear assembly.Type: GrantFiled: March 4, 1999Date of Patent: November 6, 2001Assignee: Stryker CorporationInventor: Wenjie Deng

Patent number: 6312442Abstract: Method for developing an anatomic space for laparoscopic hernia repair comprising separating a first layer of tissue from a second layer of tissue for creating an anatomic operating space for the performance of a surgical procedure by making an incision through the first layer of tissue. A non-elastomeric deflated balloon is introduced into the incision. The balloon is inflated to cause separation of the first layer of tissue from the second layer of tissue to thereby produce an anatomic operating space. The balloon is then deflated and removed from the incision. The anatomic operating space is inflated with insufflation gas. A surgical procedure in then performed in the anatomic operating space.Type: GrantFiled: June 2, 1992Date of Patent: November 6, 2001Assignee: General Surgical Innovations, Inc.Inventors: Maciej J. Kieturakis, Kenneth H. Mollenauer, Michelle Y. Monfort

Patent number: 6312444Abstract: The invention provides a medical device having an elongate catheter, a balloon occluder mounted on a distal end of the catheter, and optionally a chopping mechanism associated with an aspiration port of the catheter. Continuous or intermittent suction can be applied to the aspiration port which is distal to the occluder to dislodge thromboembolic material in a carotid or cerebral artery. Oxygenated blood or other fluid, which may be hypothermic, can be perfused through at least one perfusion port proximal to the occluder to maintain and augment perfusion of the collateral vasculature proximal to the occlusive lesion. The flow rate of blood or fluid can be controlled by rotating two cylindrical members. Neuroprotective agents or t-PA can also be infused distal to the occluder through the aspiration port or an infusing port. Methods of using the devices in treating patients with acute stroke or occlusive cerebrovascular disease are also disclosed.Type: GrantFiled: April 12, 2000Date of Patent: November 6, 2001Assignee: CoAxia, Inc.Inventor: Denise Barbut

Patent number: 6312445Abstract: Surgical clamps, tissue retractors and surgical stabilizers are disclosed having gripping surfaces from which extend resilient filaments. The distal ends of some of the resilient filaments abut against engaged vessels, tissues or organs to restrict movement of the vessels, tissue or organs relative to the gripping surfaces. In the preferred embodiment, the resilient filaments are arranged in rows and oriented at particular angles relative to the gripping surfaces. Methods of applying resilient filaments to pads for attachment to a surgical clamp, tissue retractor or surgical stabilizer are also disclosed.Type: GrantFiled: March 9, 2000Date of Patent: November 6, 2001Assignee: Novare Surgical Systems, Inc.Inventors: Thomas J.

Patent number: 6312446Abstract: A catheter delivered device to close a septal defect, the device comprising a cylindrical shaft of metal or polymeric material with concentric parallel cuts through the wall of the device which create flattened support struts. The center of the support struts move radially away from the axis in a hinge like fashion in response to the movement of the device's proximal and distal ends toward the center of the device. This movement is reversibly effected through mechanical means. The device can be coated with growth factors, mitogenic factors or other determinants which can improve tissue growth such that tissue ingrowth can occur over a period of time. The catheter itself may be an ultrasonic imaging catheter.Type: GrantFiled: September 12, 2000Date of Patent: November 6, 2001Assignee: SciMed Life Systems, Inc.Inventors: Joseph Huebsch, Paul J.

Patent number: 6312447Abstract: Devices and methods are provided for diagnosing and repairing mitral valve defects such as mitral valve regurgitation. According to an exemplary method, mitral valve function is visualized by transesophageal echocardiography. A catheter (10) is inserted along the venous system of the patient through the left and right atria (a, b) into the mitral valve (26). A suction tip (25) grasps the leaflets (28, 30) of the mitral valve (26) to immobilize and juxtapose the leaflets (28, 30) at a point simulating a stitch, and the mitral valve (26) is again observed to confirm that fastening at that point will repair the prolapse or other defect. The mitral valve leaflets (28, 30) are then fastened together via a fastener such as a staple (44) or shape memory rivet (44). The fastener (44) may be inserted by a stapling assembly (40) in the catheter (10), or by a separate stapler (40) that is inserted along an arterial path from the opposite direction and guided along a transcardiac rail to the immobilized point.Type: GrantFiled: October 13, 1999Date of Patent: November 6, 2001Assignees: The General Hospital Corporation, The Georgia Tech Research CorporationInventor: Randall Y.
