Publication number: 20070213616Abstract: A targeting catheter is used to locate an arteriotomy, such as is formed during a femoral artery catheterization procedure. The targeting catheter includes one or more targeting aids, such as an inflatable balloon or sensor (e.g., Doppler or temperature sensor), to locate the arteriotomy. The targeting aid may be positioned at the arteriotomy. An ultrasonic beacon on the catheter may then be located relative to a therapeutic ultrasonic applicator (e.g., by using acoustic time-of-flight) so that the focus of ultrasonic energy from the applicator can be aligned with the arteriotomy.Type: ApplicationFiled: October 19, 2006Publication date: September 13, 2007Inventors: Thomas Anderson, Charles Emery, Margo Gisselberg, John Kook, Larry Kulesa, Robert Pedersen, David Perozek, K.

Publication number: 20070194658Abstract: An inflatable cuff having integrated ultrasound transducers is used to effect hemostasis of deep bleeding wounds in limbs. The cuff includes a chamber defined by a bladder or a series of dams into which a fluid may be introduced and pressurized. The pressure of the fluid stops or slows bleeding while high intensity focused ultrasound is applied to effect hemostasis. The fluid may also serve as an acoustic couplant between the limb and the ultrasound transducers. The transducers may be electrostrictive transducers. Diodes may be used to reduce parallel capacitive loading in the transducer array. Bypass capacitors using the electrostrictive material may also be used.Type: ApplicationFiled: July 13, 2006Publication date: August 23, 2007Inventors: Jimin Zhang, David Perozek, John Kook, Ed Caldwell, Charles Emery, Robert Pedersen

Publication number: 20070179379Abstract: An ultrasonic applicator unit (2) is used diagnostically to locate a puncture wound (316) in an artery and then therapeutically to seal the puncture wound with high intensity focused ultrasound (HIFU). A control unit (6) coupled to the applicator unit includes a processor (74) that automates the procedure, controlling various parameters of the diagnostic and therapeutic modes, including the intensity and duration of the ultrasonic energy emitted by the applicator unit. A protective, sterile acoustic shell (4), which is intended to be used with a single patient and then discarded, is slipped over the applicator unit to protect against direct contact between the applicator unit and the patient and to maintain a sterile field at the site of the puncture. The apparatus and method are particularly applicable to sealing a puncture made when inserting a catheter into an artery or other vessel.Type: ApplicationFiled: January 4, 2007Publication date: August 2, 2007Applicant: Therus CorporationInventors: Lee Weng, David Perozek, Jimin Zhang

Publication number: 20060235300Abstract: Ultrasound applicators able to both image a treatment site and administer ultrasound therapy include an array of transducer elements that can be focused. In several embodiments, an electronically phased array is used for controlling the focal point of an ultrasound beam. The ultrasound beam produced thereby can also be electronically steered. To reduce the quality factor or Q of the array when the array is used for imaging, an electronic switch is selectively closed, placing a resistance in parallel with each of the array elements. A flexible array is employed in several embodiments and is selectively bent or flexed to vary its radius of curvature and thus control the focal point and/or a direction of focus of the array. In another embodiment, each of the transducer elements comprising the array are individually mechanically pivotable to steer the ultrasonic beam produced by the transducer elements.Type: ApplicationFiled: June 19, 2006Publication date: October 19, 2006Inventors: Lee Weng, David Perozek, Jimin Zhang

Publication number: 20050240170Abstract: Disclosed herein are methods and systems for producing hemostasis, tissue closure, or vessel closure by inserting a thermal delivery probe into a passageway and emitting thermal energy from the probe to produce the hemostasis or tissue closure. These methods and systems may be used following a percutaneous medical procedure that creates a passageway in tissue of patient, such as is caused by introduction of an access device into the patient. The thermal delivery probe may have one or more ultrasound transducers positioned in an elongated shaft.Type: ApplicationFiled: September 24, 2003Publication date: October 27, 2005Applicant: Therus CorporationInventors: Jimin Zhang, David Perozek, Lee Weng
