摘要： A device and method for mapping, diagnosing and treating the intestinal tract is provided using a capsule passing through the intestinal tract. Further, a capsule tracking system is provided for tracking a capsule's location along the length of an intestinal tract as various treatment and/or sensing modalities are employed. In one variation, an acoustic signal is used to determine the location of the capsule. A map of sensed information may be derived from the pass of a capsule. Capsules may be subsequently passed through to treat the intestinal tract at a determined location along its length. One variation uses an electrical stimulation capsule to treat and/or diagnose a condition in the intestinal tract.

摘要： Ultrasound apparatus for examining tissue in a region of interest in a body comprising a housing having a viewing aperture. An ultrasonic transducer is provided comprised of an array of ultrasonic elements disposed in the viewing aperture. Electrical pulses are supplied to the transducer for transducer excitation to introduce ultrasonic signals into the body for reflection from the tissue in the region of interest. The transducer is capable of converting ultrasonic signals reflected from the tissue within the body to the transducer to provide electrical signals. The electrical signals are gain corrected in accordance with time. In-phase and out-of-phase components of the electrical signals are provided and then digitized. The digitized electrical signals are collected to form one image for a single frame of the tissue in the region of interest in the body from transducer excitations less than thirty-three in number which is then displayed.

摘要： A guide wire having a distal extremity with an adjustable support characteristic including a core wire having proximal and distal extremities. The distal extremity has a reduced cross sectional area which is more flexible than the proximal extremity. A tip is secured to the distal extremity of the core wire. A sleeve of superelastic material is disposed coaxially on the distal extremity of the core wire. The sleeve is annealed so that it is relatively flexible at a temperature ranging from 20.degree. to 40.degree. C. and becomes progressively stiffer as temperature increases. The core wire conducts electrical energy to the superelastic sleeve to supply heat to the sleeve and extends from the proximal extremity of the core wire to the sleeve to cause the sleeve to become stiffer to thereby increase the stiffness of the distal extremity of the guide wire. A guide wire is provided having a distal extremity with an adjustable support characteristic which varies from a floppy characteristic to a stiff characteristic.

摘要： A catheter assembly for treatment of a stenosis in a lumen in a blood-carrying vessel comprising a first flexible elongate tubular member having proximal and distal extremities. A first inflatable balloon is coaxially mounted on the distal extremity of the first flexible elongate tubular member and has a main lumen and an aspiration lumen exiting through the distal extremity. A second flexible elongate tubular member has proximal and distal extremities and has a second inflatable balloon coaxially mounted on the distal extremity and has a blood perfusion lumen extending therethrough. The second flexible elongate tubular member is slidably mounted in the main lumen of the first flexible elongate tubular member. The first balloon is positioned so that it is adjacent to but proximal of the stenosis and is thereafter inflated to create a first occlusion in the lumen in the vessel. A negative pressure is created in the lumen in the vessel distal of the first balloon through the aspiration lumen. The second balloon is positioned distal of the stenosis and is inflated to create a second occlusion in the lumen of the vessel to form a working space between the first and second balloons which brackets the stenosis. Blood is perfused through the blood perfusion lumen distal of the second occlusion. A therapeutic procedure is performed in the working space.

摘要： A low profile, balloon-on-a-wire catheter comprising a flexible elongate tubular member having proximal and distal extremities. A balloon inflation-deflation lumen extends from the proximal extremity to the distal extremity. An inflatable balloon is carried by the distal extremity of the flexible elongate tubular member. The flexible elongate tubular member carries means which establishes communication between the lumen and the interior of the inflatable balloon. A removable inflation device is removably secured to the proximal extremity of the flexible elongate tubular member for supplying an inflation fluid to the lumen for inflating and deflating the balloon. The removable inflation device forms a high pressure seal with the proximal extremity of the flexible elongate tubular member. The removable inflation device is free of obstructions so that another balloon catheter can be advanced over the proximal extremity of the flexible elongate tubular member which serves as a stand-alone guide wire. The distal extremity of the catheter is formed so that it is mechanically shapeable or can be electrically deflectable to facilitate steering of the distal extremity.

摘要： A catheter probe comprising a flexible elongate tubular member having proximal and distal extremities. An expandable assembly capable of moving from a contracted position to an expanded position is secured to the distal extremity of the flexible elongate tubular member and is formed from at least two elongate members movable between contracted and expanded positions. The elongate members have extremities which are joined so that the elongate members extend at an angle relative to each other to form a vee therebetween. A plurality of longitudinally and radially spaced-apart electrodes are carried by the expandable assembly so that they can be moved into engagement with the wall of the heart when the expandable assembly is expanded into the expanded position. Electrical conductors extend through the elongate tubular member and are connected to the electrodes for performing electrical functions with respect to the electrodes. An elastomeric material is adhered to the joined extremities of the elongate members and is disposed within the vee for inhibiting the formation of thrombus on the elongate members while the expandable assembly is disposed within the blood of the heart.
