Publication number: 20140276136Abstract: The present invention generally relates to methods for detecting endoleaks associated with EVAR procedures using physiological measurements. The method can involve the taking of functional measurement data in the vicinity of a stent-graft delivered as part of the EVAR procedure and determining the presence of an endoleak based on such data.Type: ApplicationFiled: March 12, 2014Publication date: September 18, 2014Applicant: VOLCANO CORPORATIONInventors: Neil Hattangadi, David Goodman

Publication number: 20140276038Abstract: The invention generally relates to systems and methods for predicting impact of a catheter on curvature of a vessel. In certain aspects, the invention provides a system for predicting impact of a catheter on curvature of a vessel. The system includes a central processing unit (CPU) and storage coupled to the CPU for storing instructions. The stored instructions, when executed by the CPU, cause the CPU to accept as input data representative of stiffness of a catheter. The CPU is additionally caused to compare the data to a material parameters data set. The material parameters data set includes vessel displacement values for catheters of different stiffness. The CPU is additionally caused to predict impact of the catheter on a curvature of a vessel based on the comparison of the data to the material parameters data set, and to provide the prediction as an output.Type: ApplicationFiled: March 13, 2014Publication date: September 18, 2014Applicant: VOLCANO CORPORATIONInventors: Joseph Burnett, K. Matthews, Neil Hattangadi, Scott Huennekens, Bret Millett

Publication number: 20140276684Abstract: The present invention generally relates to methods for removing plaque from a vessel. The method can involve obtaining a first image of a blood vessel using a first imaging modality, obtaining a second image of the blood vessel using a second imaging modality, and coregistering the first and second images, thereby generating a coregistered data set. The method can further involve inserting an atherectomy catheter into the blood vessel and removing plaque from the vessel with the atherectomy catheter based on plaque identified in the coregistered set of data.Type: ApplicationFiled: March 11, 2014Publication date: September 18, 2014Applicant: VOLCANO CORPORATIONInventors: Scott Huennekens, Neil Hattangadi

Publication number: 20140052105Abstract: The present disclosure is directed to a catheter for site-specific delivery of a therapeutic agent to a blood vessel of a patient. The catheter further includes an elongated shaft having at least one inner lumen, a distal end and a proximal end and proximal and distal vessel-conforming balloons where each is separately positionable and inflatable, and when inflated, substantially restricts blood flow in the vessel and creates a treatment window of a defined but variable length for delivery of the therapeutic agent. The catheter optionally includes at least one marker band adjacent to the proximal balloon and at least one marker band adjacent to the distal balloon. At least one lateral aperture positioned in the window is in fluid communication with a drug delivery conduit located within either the inner shaft or the outer shaft to provide a homogeneous concentration of the therapeutic agent to the window.Type: ApplicationFiled: November 5, 2013Publication date: February 20, 2014Applicant: Covidien LPInventors: Neil Hattangadi, Daniel Lerner, Ryan Olivera
