For example, in some embodiments, a tricuspid insufficiency treatment device is provided, and includes a tubular member configured for implantation within a vena cava of a patient, where the tubular member is formed with a sidewall. The device also includes at least two (2) valves arranged circumferentially along the sidewall, where each valve comprises an opening formed in the sidewall, and a blocking member arranged to block and unblock a respective opening of the plurality of openings. Each blocking member comprises a flap or cover pivotally attached at or proximate a portion of a respective opening and arranged to block and unblock the opening during ventricular systole and ventricular diastole, respectively, such that the opening is unblocked in a direction opposite to the attachment of the flap or cover.Type: ApplicationFiled: December 8, 2020Publication date: March 25, 2021Applicant: Innoventric Ltd.Inventors: Ori NISSAN, Amir DANINO, Yair PICHERSKY

Publication number: 20210085495Abstract: A prosthesis includes a radially expanded configuration and a radially compressed configuration. The prosthesis further includes a material layer and a stent. The material layer is generally tubular and has a first diameter when the prosthesis is in the radially expanded configuration. At least a portion of the stent has an unrestrained diameter that is larger than the first diameter of the material layer at a location where the portion of the stent is coupled to the material layer, thereby making the portion of the stent oversized relative to the material layer at the coupling location. The stent may comprise a plurality of stent rings aligned adjacent to each other defining a central passageway, with at least one of the stent rings having an unrestrained diameter larger than the first diameter of the material layer at the coupling location.Type: ApplicationFiled: September 24, 2019Publication date: March 25, 2021Inventors: Cathleen A. Bergin, Michael James Schendel, Scott Robertson

Publication number: 20210085496Abstract: A growth stent and valve and methods for making and using the same. The growth stent and valve may be delivered to treat early stage congenital lesions, while expanding to adult vessel diameters. In selected embodiments, the growth stent and valve can comprise a frame and may have a covering on some portion to prevent blood flow through a wall of the frame. The growth stent and valve advantageously can maintain radial strength across an entire range of diameters necessary to treat a narrowed lesion from birth and childhood through adulthood as the vessels grow over the lifetime of a patient.Type: ApplicationFiled: December 10, 2020Publication date: March 25, 2021Inventors: Dustin Armer, Eason Abbott

Publication number: 20210085497Abstract: Systems, devices, and methods for retracting a pull wire from a hypotube can include positioning a pull wire having an engagement bump on its proximal end within a channel of a device and sliding the pull wire proximally through a channel of a device by moving grippers of the device proximally to engage and slide the bump. Subsequent distal movement of the grippers can result in the grippers disengaging the bump without disturbing the position of the pull wire or causing the pull wire to move distally.Type: ApplicationFiled: October 12, 2020Publication date: March 25, 2021Applicant: DePuy Synthes Products, Inc.Inventors: Daniel SOLAUN, David BLUMENSTYK

Publication number: 20210085498Abstract: A medical device system may include an elongate shaft having a lumen extending from a proximal end to a distal end, a proximal release wire, and a distal release wire. The proximal release wire may extend distally from a proximal end configured to remain outside the body to a distal end and may be slidably disposed within the lumen of the elongate shaft. The distal release wire may extend distally from a proximal end to a distal end and may be slidably disposed within the lumen of the elongate shaft. The proximal end of the distal release wire may be slidably coupled to the distal end of the proximal release wire. The distal release wire may be configured to releasably attach a medical device to the distal end of the elongate shaft.Type: ApplicationFiled: September 22, 2020Publication date: March 25, 2021Applicant: BOSTON SCIENTIFIC SCIMED, INC.Inventors: ERIC NYGAARD, NICHOLAS LEE TASSONI

Publication number: 20210085499Abstract: Gastrointestinal implants can be used to secure thin-walled sleeves, restrictor plates, and other devices within the gastrointestinal tract. An example implant includes three elements: a stomach anchor to resist distally oriented forces; a duodenal anchor to resist proximally oriented forces; and a connector element to keep the stomach anchor fixed relative to the stomach anchor. The implant is inserted into the gastrointestinal tract with a delivery device that holds the implant in a compressed state for minimally invasive delivery until the implant is positioned properly. Upon releasing from the delivery device, the implant expands to a relaxed state across the pylorus, allowing prongs that extending outward from the stomach and duodenal anchors to engage tissue in the gastrointestinal tract. The deployed implant may also include a thin-walled sleeve that extends into the intestine from the stomach anchor, duodenal anchor, or connector element.Type: ApplicationFiled: May 18, 2020Publication date: March 25, 2021Inventors: Sean K. HOLMES, Barry MAXWELL, Ezra S. FISHMAN

Publication number: 20210085500Abstract: Real-time cast sensor measurement outputs of a set of cast sensors that each measure a characteristic related to usage of an adjustable removable cast worn by a patient during treatment of congenital talipes equino varus (CTEV) are monitored. A cast usage anomaly relative to a treatment program prescribed for the patient with respect to wearing of the adjustable removable cast is identified according to the real-time cast sensor measurement outputs. Responsive to identifying the cast usage anomaly, real-time corrective treatment feedback is provided to the patient that instructs further and proper use of the adjustable removable cast to improve compliance with the treatment program prescribed for the patient.Type: ApplicationFiled: December 4, 2020Publication date: March 25, 2021Inventors: Igor S. Ramos, Ana C. Biazetti
