  • Patent number: 6309379
    Abstract: An intravascular device, such as a sheath, and methods for use thereof for selective alternate positioning of other intravascular devices having predetermined sizes in a distal vascular region of the body of a patient. The intravascular selection sheath comprises a tubular body having proximal, intermediate and distal sections and a lumen extending therethrough. The portion of the lumen in the distal section can be occupied by only one of the other intravascular devices of the predetermined sizes at a given time. The portion of the selection sheath lumen in the intermediate section can be occupied by at least two intravascular devices of the predetermined sizes in a side by side relationship. In operation, the two other intravascular devices occupy positions in the lumen in the intermediate section of the selection sheath. First, one of the intravascular devices can be advanced into the lumen in the distal section of the selection sheath and then withdrawn back into the intermediate section.

  • Patent number: 6066100
    Abstract: An intravascular device such as an introducer sheath or a balloon catheter, and methods for use thereof, comprising an elongate member having a proximal end and a distal end and a first lumen and a second lumen. The first lumen communicates with a first proximal opening at the proximal end of the elongate member and with a distal opening at the distal end of the elongate member. The second lumen terminates distally and communicates with the first lumen at a location proximal of the first distal opening and has a proximal opening located proximally therefrom. One or more perfusion openings may be located in the device to allow blood flow therethrough. The proximal opening of the second lumen may be located distally of the proximal opening of the first lumen. A balloon may be located on a distal portion of the elongate shaft.

  • Patent number: 5833688
    Abstract: A dual temperature sensor assembly is used in an ablation catheter. The sensor assembly includes a thermistor and a thermocouple. The ablation catheter has a body with a distal end and a proximal end. An ablation member (e.g., an electrode for providing energy) is disposed at the distal end of the body for ablating tissue. The sensor assembly allows the ablation catheter to be used with any known generator/controller unit, either the thermistor-based kind or the thermocouple-based kind.

  • Patent number: 5445155
    Abstract: A device for ultrasonic imaging, and methods for the use an manufacture thereof, particularly of small coronary vessels. The device comprises an elongate member with a distal end that can be positioned within a small vessel of a patient's body while a proximal end is located outside the body, a transducer located at a distal end of the elongate member and operable to scan the distal coronary vessels with ultrasonic pulses, and a signal processor connected to a proximal end of the elongate member and to the transducer for generating and receiving pulses to and from the transducer. A motor may be also connected to the proximal end of the elongate member for rotating the transducer.
