Patent number: 11682320Abstract: A device and system for simulating normal and disease state cardiovascular functioning, including an anatomically accurate cardiac simulator for training and medical device testing. The system and device uses pneumatically pressurized chambers to generate ventricle and atrium contractions. In conjunction with the interaction of synthetic valves, which simulate mitral and aortic valves, the system is designed to generate pumping action that produces accurate volume fractions and pressure gradients of pulsatile flow, duplicating that of a human heart. Through the use of a control unit and sensors, one or more parameters, such as flow rates, fluidic pressure, and heart rate, may be automatically controlled, using feedback loop mechanisms to adjust parameters of the hydraulic system to simulate a wide variety of cardiovascular conditions including normal heart function, severely diseased or injured heart conditions, and compressed vasculature, such as hardening of the arteries.Type: GrantFiled: September 20, 2019Date of Patent: June 20, 2023Assignee: Mentice, ABInventors: Chandramouli Sadasivan, Baruch B.

Patent number: 10201359Abstract: A method of increasing blood flow through an obstructed blood vessel includes providing an expandable member substantially made of a mesh having a plurality of interstices. The expandable member is inserted into the blood vessel, positioned within the blood vessel with the proximal member end upstream of the distal member end and the member body located radially adjacent at least a portion of an obstruction, and expanded to bring at least a portion of the member body into contact with the obstruction. An outward radial force is exerted on the obstruction to dislodge at least one fragment from the obstruction and to enhance blood flow through the blood vessel past the obstruction. The at least one fragment is passed through at least one interstice of the member body in the radial direction, and is selectively retained within the expandable member.Type: GrantFiled: November 8, 2012Date of Patent: February 12, 2019Assignee: CLEVELAND CLINIC FOUNDATION, THEInventors: David Fiorella, Henry Woo

Patent number: 9662066Abstract: A sensor system for sensing a stimulus in vivo includes an implantable sensor. The sensor comprises a passive resonator circuit having a resonant frequency and including at least a pair of generally parallel spirally wound unconnected conductive coils sandwiching a layer of solid dielectric material that manifest a change in property affecting the resonant frequency in response to application of the stimulus to the layer. A resonant frequency of the sensor is modulated by altering the spacing or gap between the coils or altering the overlapping area of the coils. The sensor is energized through application of radiofrequency energy and the responding resonant frequency is detected. The sensor can be advantageously attached to a medical implant to form a practical smart implant for clinical purposes.Type: GrantFiled: February 5, 2013Date of Patent: May 30, 2017Assignee: IO Surgical, LLCInventors: Eric Howard Ledet, Rebecca Ann Wachs, Keegan Paul Cole, David Fiorella

Patent number: 9504588Abstract: A system, method, computer-readable medium, apparatus, and device for simulating placement of an expandable device in a cavity is provided. For example, a three or more dimensional image of a cavity, e.g., a tubular cavity, geometry is acquired. A centerline of the cavity, and a perimeter of the cavity based on the centerline of the cavity and the three-dimensional image of the cavity geometry, are determined. The length of a wire of the expandable device as the wire rotates along the perimeter of the cavity in a deployment direction is determined. A pitch of the rotation of the wire based on a local diameter at the centerline site of rotation and in-air parameters of the expandable device is determined. A deployed device length of the expandable device along the centerline of the cavity is determined. A processor is usable to determine and/or calculate each of the above.Type: GrantFiled: June 5, 2012Date of Patent: November 29, 2016Assignee: The Research Foundation for The State University of New YorkInventors: Chandramouli Sadasivan, Baruch Barry Lieber, David Fiorella, Henry Woo
