    摘要: Guide wire for use in a medical procedure and for use with a power supply comprising a solid core wire having proximal and distal extremities. The proximal extremity has a predetermined diameter. At least a portion of the distal extremity has a reduced size with respect to the predetermined diameter. A flexible coil is secured to the distal extremity of the core wire and extends over the portion of the core wire having a reduced size. An actuator member is disposed proximal of the coil and extends along the core wire. Electrical conductors extend from the proximal extremity of the core wire to the actuator member for supplying heat to the actuator member. The actuator member is formed of a temperature activated metal alloy having a Young's modulus of 4.times.10.sup.6 to 14.times.10.sup.6 psi which increases in stiffness when heat is supplied thereto to increase the stiffness of the guide wire proximally of the coil.

    摘要: A guide wire with extension capability for use in a medical procedure having a guide wire and a guide wire extension. The guide wire comprises a flexible elongate cylindrical member having proximal and distal extremities. A portion of the distal extremity is formed of a material having high torquability and high pushability. The guide wire extension comprises a flexible elongate cylindrical member formed of a shape memory material. A major portion of the flexible elongate cylindrical member of the guide wire extension has a shape memory in the form of a coil so that when it is free it will assume a shape memory coil. A junction is formed between the proximal extremity of the guide wire and the distal extremity of the guide wire extension for connection of the guide wire extension to the guide wire.

    摘要: A guide wire having a distal extremity with an adjustable support characteristic comprising 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 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 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 device, system and method for diagnosing and treating gastric disorders is provided. A functional device resides within the patient's stomach and is secured to the stomach wall by an attachment device. The functional device may be a sensor for sensing various parameters of the stomach or stomach environment, or may be a therapeutic delivery device. The functional device in one embodiment provides a device, system and method for gastric electrical stimulation where stimulating electrodes are secured to the wall of the stomach by the attachment device or otherwise. A preferred device includes: at least one stimulating electrode in electrical contact with the stomach wall; an electronics unit containing the electronic circuitry of the device; and an attachment mechanism for attaching the device to the stomach wall. The functional devices may be programmed to respond to sensed information or signals. An endoscopic delivery system delivers the functional device through the esophagus and into the stomach where it is attached the stomach wall. The endoscopic instruments attach or remove the attachment devices and functional devices from the stomach and may be used to assist in determining the optimal attachment location.
