    摘要： Described in one aspect is a multi-pressure monitoring system for cell or other therapy includes a first catheter having a first lumen for accepting a treatment device, a second lumen for inflating a balloon, a pressure sensor for monitoring fluid pressure within the first lumen, and a flow restrictor such as a hemostasis valve for limiting the exchange of fluids into and out of the first lumen while treatment devices are present or exchanged in the first lumen. Also disclosed is a method of using the first catheter with a first pressure monitor coupled to the first pressure sensor along with a second catheter attached to a second pressure sensor coupled to a second pressure monitor. The second catheter is positioned within the first lumen of the first catheter during treatment operations and the first and second pressure monitors are used to verify proper pressures throughout the procedure. Described also are novel methods, systems, and catheters for delivering flowable therapeutic substances, such as viable cellular preparations, to patients.

    摘要： Described are methods and systems and system components useful for percutaneously delivering or retrieving vascular implant devices, such as filters, utilizing intravenous ultrasound (IVUS) imaging alone or in combination with external (e.g. transabdominal) ultrasound or other imaging technology. Implants deliverable by such systems, such as vena cava or other vascular filters, can have two or more echogenic markers spaced at such a distance that they are separately discernible by IVUS and/or external ultrasound imaging.

    摘要： A system for use with ultrasound procedures including an ultrasound control and/or imaging system which has a microminiature motor, a rotatable reflector and a stationary ultrasound transducer. The transducer may be placed between the motor and the reflector, so as to eliminate the need for placement of wires or other artifact-creating items in the path of ultrasound signals. In particular embodiments, such systems can be incorporated in or retrofitted to commercially standard diagnostic and therapeutic catheters or other housings. Examples can be used in variety of ultrasound procedures, e.g. to perform intravascular ultrasound (IVUS) imaging.
