Filed:

May 18, 1999

Appl. No.:

09/315383

Inventors:

Assignee:

Wilk Patent Development Corp. - New York NY

International Classification:

A61B 1900

US Classification:

128898, 606 7

Abstract:

A cardiovascular treatment method utilizes an elongate flexible surgical instrument (e. g. , catheter) having a distal end. A distal end portion of the instrument is inserted into a vascular system of a patient. A surgical head at the distal end of the instrument is positioned so that the head is disposed adjacent to myocardium tissue of the patient. The head is operated to form a recess in the myocardium tissue. Prior to operating the head to form the recess, a thickness of the myocardium tissue is measured, the recess formed during the operation having a length determined in accordance with the measured thickness of the myocardium tissue. The thickness measurement partially determines the length of the recess. The angle of entry of the recess with respect to the heart wall also partially determines the length of the recess: the greater the angle, the longer the recess can be for a given myocardium thickness.

Abstract:

Described herein are various methods and apparatuses for delivering stents or conduits and other devices into the myocardium of a patient. One preferred stent delivery system provides access to the insertion site in the myocardium by advancing a delivery catheter through a blockage in a coronary artery, or around the blockage through a coronary vein or through a channel or tunnel formed around the blockage. In one embodiment, once the distal end of the delivery catheter is adjacent the myocardium, an angled bend is created in the catheter by actuating expandable steering guides mounted to the catheter which cooperate with the walls of the blood vessel to cause the catheter to turn. Then, a guidewire is advanced through the delivery catheter and into the myocardium. In another embodiment, a tip-deflecting pull wire extends from the distal end of the delivery catheter which may be actuated to turn towards and then inserted into the myocardium. In another embodiment, an exit port facing the insertion site is provided within the catheter or a balloon mounted on the catheter so that a guidewire may be directed through a lumen and out the exit port into the:.

US Classification:

600586, 600484, 600587

Abstract:

A medical diagnostic device comprises a substrate or carrier, a plurality of acoustoelectric transducers or sensors attached to the substrate or carrier in a pre-established array, a signal processor operatively coupled to the transducers for determining locations of points of origin of acoustic pressure waves generated by internal tissue structures of a patient on whom the substrate or carrier is placed, and a diagnosis computer operatively coupled to the transducers for automatically analyzing signals from the transducers to determine an internal condition of the patient. The device optionally includes a plurality of mechanical probes movably mounted to the substrate or carrier and actuators operatively connected to the probes for inducing movement of the probes, in a direction perpendicular to the substrate or carrier, from nascent or retracted positions to extended positions. The computer is operatively connected to the actuators for varying extension rate of the probes and for inducing a predetermined sequence of actuation of the probes. A plurality of additional sensors may be mounted to the substrate or carrier for measuring a preselected physiological parameter at different locations along a patients skin surface.

US Classification:

Abstract:

A medical diagnostic apparatus includes a carrier body, a plurality of rigid substrates each bearing at least one solid-state gamma ray sensor, the substrates being attached to the carrier body, and a computer operatively connected to the sensors for receiving signals therefrom and deriving information about location and size of a source of radioactivity in the patient. The carrier body enables disposition of different gamma ray sensors on different sides of the patient so that the sensors at least partially surround the patient. In an associated medical diagnostic method, a chemical composition containing a radioactive isotope is administered to a patient. A plurality of solid-state sensors sensitive to gamma rays generated by radioactive decay of the isotope are subsequently disposed about the patient, and signals from the sensors are conducted to a computer, which is then operated to derive information about location and size of a source of radioactivity in the patient. The sensors may be mounted to a flexible web which is manipulated to conform to the patient.

Abstract:

A golf course has a single fairway with multiple greens. At least two greens are provided, at opposite ends of the fairway. One or more additional greens may be provided between the first two greens and along the fairway. Also, multiple tees are provided for the one fairway. At least one tee is provided at each end of the fairway, the tee facing down the fairway towards the green at the opposite end of the fairway. Each green may be the target of two or more tees disposed at different locations on the fairway. The golf course is occupied for a predetermined limited period of time by an individual or a single group of golfers. The individual or single group of golfers plays back and forth along the fairway, for as long as they have reserved the course. They can play at their own pace, undisturbed by other golfers because there are no other golfers on the course. The only limitation is duration: eventually they will have to stop because their reserved interval of play has terminated.

International Classification:

US Classification:

606142, 606205

Abstract:

A surgical clamping device comprises a first jaw and a second jaw, with a self-locking surgical fastener mountable thereon. The jaws have at least a first closing configuration and a second closing configuration, the first closing configuration designed to reduce a lateral dimension of a clamping device with mounted fastener, without thereby engaging locking devices on the selflocking surgical fastener, the second closing configuration designed to cause an engagement of the self-locking devices, thereby allowing a demounting of the fastener and a permanent disposition thereof in tissue. In a first closing configuration an approximation of the jaws in a transverse plane thereof is accompanied by an out-of-plane movement, comprising translation, or rotation about an axis in the plane, the rotation in turn comprising twistingârotation about an axis essentially parallel to a longitudinal axis of the jaws, or skewingârotation about an axis essentially perpendicular to a longitudinal axis of the jaws. An alternative engagement of the first closing configuration and the second closing configuration is effected by a ratcheting device in conjunction with a camming device, or any means of actuation known in the mechanical arts.

Abstract:

A method for dental plaque removal intended for consumer use comprises filling the mouth with a physiologically acceptable cleaning solution, solvent, or wash, holding such solution in the mouth under voluntary muscular control, thereafter inserting through the lips an elongate acoustically excitable probe forming, under muscular control, a seal with the lips. The probe is energized and a sonic or ultrasonic cleaning action in the mouth removes incipient plaque deposits from the teeth, without the necessity of visiting each tooth individually with a manual or partially automatic mechanical cleaning implement, such as a toothbrush. In an alternative embodiment, fluid fill is provided through a channel in the probe and filling of the mouth is accomplished following insertion. The method may be used in a more general sense to acoustically clean articles in a flexible portable enclosure by means of a portable probe or tool.
