Patent number: 10874376Abstract: An endobronchial probe includes a deflector having a bore extending therethrough at an angle to its long axis for passage of a tool. The probe includes a location sensor and an ultrasound imager. A push-pull anchoring system comprises a plurality of guides and wires that can extend beyond the guides and retract within the guides. When extended the wires diverge from the long axis sufficiently to engage a bronchus. The probe includes a balloon disposed on the distal segment contralateral to bore that when inflated urges the mouth of the bore into contact with the bronchial wall.Type: GrantFiled: January 18, 2017Date of Patent: December 29, 2020Assignee: Biosense Webster (Israel) Ltd.Inventors: Jonathan Reuben Waldstreicher, William Sanford Krimsky, Yitzhack Schwartz, Avi Shalgi, Meir Bar-Tal, Matityahu Amit, Gal Hayam, Refael Itah, Robert D.

Publication number: 20090326574Abstract: A method of treating vulnerable plaque comprising intentionally damaging or rupturing the vulnerable plaque using a wingless balloon which is inflated from a wingless unexpanded diameter to a limited expanded diameter. This process produces significant increase in ECM synthesis at the site of the damage or rupture. As a result, the method strengthens the vulnerable plaque while minimizing or avoiding damage to the surrounding wall of the body lumen or damaging a stable plaque mistakenly believed to be a vulnerable plaque. The method of the invention is particularly useful in treating a fibroatheroma type of vulnerable plaque. In one embodiment, the balloon is self-limiting such that it expands compliantly at initial inflation pressures, and above nominal pressure it expands noncompliantly. In an alternative embodiment, the balloon is inflated using a diameter-limiting device, such as a device which limits the inflation pressure or the volume of inflation fluid in the balloon.Type: ApplicationFiled: June 17, 2009Publication date: December 31, 2009Inventors: Deborah L. Kilpatrick, Robert D. Ainsworth, Murthy V. Simhambhatla, Jeong S. Lee
