Publication number: 20200179050Abstract: An insertable catheter device includes a shaft including a proximal end and a distal end, an expandable balloon, and an actuator configured to expand and retract the expandable balloon. The actuator includes a fluid conduit that extends through the shaft and is coupled with the expandable balloon to enable inflation and retraction of the expandable balloon via injection or withdrawal of a fluid to or from the expandable balloon via the fluid conduit. The expandable balloon is displaceably retractable into the shaft and extendable from the shaft. A fluid pump is coupled with the fluid conduit to pump the fluid through the fluid conduit. A patch is positioned to be displaced by the expandable balloon when the expandable balloon is inflated, and the expandable balloon is displaceably retractable into the shaft and displaceably extendable from the shaft.Type: ApplicationFiled: February 4, 2020Publication date: June 11, 2020Applicants: President and Fellows of Harvard College, The Brigham and Women's Hospital, Children's Medical Center Corporation, Massachusetts Institute of TechnologyInventors: Conor J.

Publication number: 20200094290Abstract: Systems and methods for sorting utilizing an inflatable actuator are disclosed. A sorting system utilizing an inflatable actuator includes an inflatable actuator. The inflatable actuator is disposed in a cantilever beam orientation atop a support surface. The system includes an inflation component coupled to the inflatable actuator to provide an inflation force. Additionally, the system includes a control component configured to send an activation signal to the inflation component responsive to a detection of an object to be sorted. Responsive to the activation signal, the inflation component inflates the inflatable actuator to cause the inflatable actuator to make contact with the object to be sorted. The contact of the inflatable actuator with the object to be sorted causes the object to change from a first trajectory to a second trajectory.Type: ApplicationFiled: September 23, 2019Publication date: March 26, 2020Inventors: Panagiotis Polygerinos, Saivimal Sridar, Pham Huy Nguyen, Wenlong Zhang

Patent number: 10588695Abstract: An insertable light-dispensing catheter device, comprising a shaft including a proximal and distal end, a light guide extending through the shaft, and a mirror displaceably extendable from the catheter into a position where the mirror receives and reflects light emitted from the light guide. The mirror can be in the form of a coating on an inflatable balloon; and the balloon, when inflated, can press a patch against a defect (e.g., a ventricular septical defect), while the light cures an adhesive that binds the patch to the structure with the defect, thereby remedying the defect.Type: GrantFiled: May 13, 2015Date of Patent: March 17, 2020Assignees: President and Fellows of Harvard College, The Brigham and Women's Hospital, Children's Medical Center Corporation, Massachusetts Institute of TechnologyInventors: Conor J.

Publication number: 20190029914Abstract: A soft-inflatable exosuit for knee rehabilitation is fabricated in two different beam-like structures (I and O cross-section actuators) and mechanically characterized for their torque performance in knee-extension assistance. The fabrication procedure of both types of actuators is presented as well as their integration into a light-weight, low-cost and body-conforming interface. To detect the activation duration of the device during the gait cycle, a soft-silicone insole with embedded force-sensitive resistors (FSRs) is used. In evaluation studies, the soft inflatable exosuit device is tested for its ability to reduce muscle activity during the swing phase of the knee. Using sEMG (surface electromyography) sensors, the rectus femoris muscle group of a healthy individual is recorded while walking on a treadmill at a constant speed, with and without the soft device.Type: ApplicationFiled: July 31, 2018Publication date: January 31, 2019Inventors: Panagiotis Polygerinos, Saivimal Sridar, Trent Maruyama, Christopher St. Clair, Christina Kwasnica

Publication number: 20110071436Abstract: A sensor is described for detecting the force applied to or by soft material, and that is thus able to measure the stiffness of a soft material. The sensor comprises a sensor body into which is supplied a fluid under pressure. At least one sensor members are provided that are arranged to project from the sensor body under the pressure exerted thereon by the fluid. A sensor member displacement detection system is also provided, that is preferably optically based using optical fibres to illuminate the sensor member and that measures the modulation of the light reflected from the sensor member as the member is displaced against the pressure of the fluid to detect and measure the displacement. From the measured displacement an estimate of the force being applied to the sensor member can be obtained. The sensor is of a small size suitable for use during MIS or catheterisation procedures. Preferably the sensor is constructed of non-metallic material such that it is MRI compatible.Type: ApplicationFiled: June 4, 2009Publication date: March 24, 2011Inventors: Kaspar Althoefer, Dinusha Zbyszewski, Pinyo Puangmali, Panagiotis Polygerinos, Lakmal Seneviratne
