Publication number: 20240024107Abstract: Anchors for securing an implant within a body organ and/or reshaping a body organ are provided herein. Anchors are configured for deployment in a body lumen or vasculature of the patient that are curved or conformable to accommodate anatomy of the patient. Such anchors can include deformable or collapsible structures upon tensioning of a bridging element in a lateral direction, or segmented tubes that can be adjusted by tightening of one or more tethers extending therethrough. Such anchors can be used as a posterior anchor in a blood vessel in implant systems having a tensioned bridging element extending between the posterior anchor and an anterior anchor deployed at another location within or along the body organ. Methods of deploying such anchors and use of multiple anchors or multiple bridging elements to a single anchor are also provided.Type: ApplicationFiled: September 28, 2023Publication date: January 25, 2024Inventors: Timothy R. Machold, David A. Rahdert, Robert T. Chang, Ganesh Manoharan

Publication number: 20210361427Abstract: Implants or systems of implants and methods apply a selected force vector or a selected combination of force vectors within or across the right atrium, which allow tricuspid valve leaflets to better coapt. The implants or systems of implants and methods make possible rapid deployment, facile endovascular delivery, and full intra-atrial retrievability. The implants or systems of implants and methods also make use of strong fluoroscopic landmarks. The implants or systems of implants and methods make use of an adjustable implant. The implants or systems of implants and methods may utilize a bridge stop to secure the implant.Type: ApplicationFiled: August 6, 2021Publication date: November 25, 2021Inventors: Robert T.

Patent number: 10849744Abstract: The disclosure pertains to a vessel for holding replacement heart valves and associated positioning and installation apparatus which is configured and adapted to contain a biocidal sterilization fluid during and following exposure of a delivery system for the replacement heart valve to sterilization by ionizing radiation and methods of use therefor. The vessel includes a shield which limits exposure of biologically derived material therein to radiation. The vessel also provides a storage and shipping container for the replacement heart valve in which the biologically derived material is maintained in a sterile fluid environment.Type: GrantFiled: June 15, 2017Date of Patent: December 1, 2020Assignee: Boston Scientific Scimed, Inc.Inventors: Robert T.

Publication number: 20200223598Abstract: Single-dose vials for liquid solutions (e.g., liquid medicaments) can be designed to be used in conjunction with a medication regimen. A single-dose vial may include a removable member that prevents a liquid solution from escaping, but also allows an individual (e.g., a patient or a medical professional) to readily administer the liquid solution. A single-dose vial could include one or more discrete capsules that include the same or different liquid solutions. For example, multiple capsules could be arranged within a vial so that different liquid solutions are simultaneously or sequentially ejected following removal of the removable member and application of pressure to the multiple capsules (e.g., due to the individual squeezing the vial). Multiple vials can also be connected to one another in a strip configuration, which allows the individual to more easily adhere to a medication regimen that requires multiple doses over a period of time.Type: ApplicationFiled: December 2, 2019Publication date: July 16, 2020Inventors: Robert T. Chang, Paolo De Marino, Manishi A. Desai

Publication number: 20200139165Abstract: Systems and methods for respiratory health management are provided. An air filtration and analysis system may comprise an apparatus configured to be worn by a user. The apparatus may comprise a filtration device. The system may also include a plurality of sensors configured to collect data. A portion of the sensor data may be indicative of (i) one or more characteristics of the air inhaled and/or exhaled by the user, and/or (ii) an environment in which the user is located. At least one sensor and/or the apparatus may be in communication with a processor that is configured to analyze the collected sensor data.Type: ApplicationFiled: January 3, 2020Publication date: May 7, 2020Inventors: Eric R.
