Publication number: 20050043626Abstract: The present invention provides an apparatus and a method for an ultrasonic medical device having a flexible material engaging an ultrasonic probe. The flexible material surrounds a portion of a longitudinal axis of an ultrasonic probe of the ultrasonic medical device. The flexible material may extend beyond a probe tip. The flexible material cushions a tip of the ultrasonic probe and reduces the stresses on the ultrasonic probe as the ultrasonic probe is navigated within the vasculature. The ultrasonic probe may be shaped to increase a radial span of the ultrasonic medical device. In a preferred embodiment of the present invention, the flexible material comprises a polymer material. Additionally, the flexible material may have a high radiopacity.Type: ApplicationFiled: August 22, 2003Publication date: February 24, 2005Inventors: Rebecca Marciante, Bradley Hare, Robert Rabiner, Anthony O'Leary, Mark Varady, Janniah Prasad, Anita Chuang

Publication number: 20040171981Abstract: The present invention provides an apparatus and a method of using an ultrasonic probe with a pharmacological agent to enhance an occlusion treating effect of the ultrasonic probe to effectively remove an occlusion. The pharmacological agent is released through a catheter to treat the occlusion and enhance an effect of a transverse ultrasonic vibration of the ultrasonic probe to effectively remove the occlusion. The pharmacological agent continues to travel downstream of the site of the occlusion and work in conjunction with the ultrasonic probe to reduce the occlusion to a size that can easily be removed from the body naturally in order to prevent reformation of the occlusion and other health risks.Type: ApplicationFiled: March 12, 2004Publication date: September 2, 2004Applicant: OmniSonics Medical Technologies, Inc.Inventors: Robert A.

Publication number: 20040162571Abstract: An apparatus and method for an ultrasonic medical device to treat deep vein thrombosis. The ultrasonic medical device comprises an ultrasonic probe having a proximal end, a distal end and a longitudinal axis therebetween. The ultrasonic probe is inserted into a deep vein of a leg, navigated adjacent to a thrombus in the deep vein and placed in communication with the thrombus. An ultrasonic energy source is activated to generate a transverse ultrasonic vibration along at least a portion of the longitudinal axis of the ultrasonic probe. The transverse ultrasonic vibration creates a plurality of transverse nodes and a plurality of transverse anti-nodes along the longitudinal axis of the ultrasonic probe, generating cavitation in a medium surrounding the ultrasonic probe to ablate the thrombus and treat deep vein thrombosis.Type: ApplicationFiled: February 13, 2004Publication date: August 19, 2004Applicant: OmniSonics Medical Technologies, Inc.Inventors: Robert A.

Publication number: 20040158151Abstract: An ultrasonic tissue ablation device comprising a transversely vibrating elongated probe, and a coupling assembly for probe attachment and detachment that enables the probe assembly and separation from the device body that includes the ultrasound energy source and a sound conductor, and a method of use for removal of vascular occlusions in blood vessels. The coupling assembly enables incorporation of elongated probes with small cross sectional lumens such as a catheter guidewires. The probe detachability allows insertion manipulation and withdrawal independently of the device body. The probe can be used with acoustic and/or aspirations sheaths to enhance destruction and removal of an occlusion. The horn assembly of the device that contains a sound conducting horn functions as an energy regulator and reservoir for the probe, and precludes loss of probe cavitation energy by its bending or damping within the blood vessel.Type: ApplicationFiled: February 4, 2004Publication date: August 12, 2004Applicant: OmniSonics Medical Technologies, Inc.Inventors: Kevin Ranucci, Robert A.

Publication number: 20040073244Abstract: A method and apparatus for removing plaque, fatty deposits, and other occlusions from blood vessels using ultrasonic energy. The method and apparatus has particular application in removing plaque from the carotid artery in a non-thermal manner. The apparatus is designed to have as small a cross-sectional profile as possible, therefore allowing the apparatus to be used in a minimally-invasive manner. As a result, the apparatus can be used in both surgical and outpatient treatment with minimal post-operative complications and minimal damage to areas other than the area of treatment. An ultrasonic probe may include aspiration channels on its outer surface. An aspiration sheath may surround the ultrasonic probe, such that the location of an aspiration port may be varied axially relative to the ultrasonic tip.Type: ApplicationFiled: August 6, 2003Publication date: April 15, 2004Applicant: OmniSonics Medical Technologies, Inc.Inventors: Robert A.
