Patent number: 11602637Abstract: The capsule comprises a tubular body and a front-end unit with an helical screw for anchoring the capsule to a wall of a patient's organ. The front-end unit is mobile in relative axial rotation with respect to the tubular body. A disengageable frictional coupling member allows this relative rotation when, for implantation, the tubular body receives an external rotational stress, and that until a predetermined limit torque triggering the disengagement. At explantation, this disengagement is prevented to allow a joint rotation of the tubular body and of the front-end unit and the unscrewing of the helical screw. It is provided for that purpose two conjugated plates facing each other, with flat surfaces such as circular sectors offset in opposite directions with respect to a radial reference plane, in such a way as to form steps providing an anti-disengagement abutment function.Type: GrantFiled: November 17, 2021Date of Patent: March 14, 2023Assignee: CAIRDACInventors: Willy Regnier, An Nguyen-Dinh

Patent number: 10751529Abstract: Methods and devices for separating an implanted object, such as a pacemaker lead, from tissue surrounding such object in a patient's vasculature system. Specifically, the surgical device includes a handle, an elongate inner sheath and a circular cutting blade that extends from the distal end of the sheath upon actuating the handle. The circular cutting blade is configured to engage the tissue surrounding an implanted lead and cut such tissue in a coring fashion as the surgical device translates along the length of the lead, thereby allowing the lead, as well as any tissue remaining attached to the lead, to enter the device's elongate shaft. The surgical device has a barrel cam cylinder in the handle assembly that imparts rotation of the blade and a separate cam mechanism in the tip of outer sheath assembly that imparts and controls the extension and retraction of the blade.Type: GrantFiled: August 26, 2016Date of Patent: August 25, 2020Assignee: SPECTRANETICS LLCInventors: Kenneth P. Grace, Weston H. Lee, Brian E. Kagarise, Robert L. Carver

Patent number: 10639066Abstract: A system for controlling displacement of an intervention device having an end for inserting in a patient body, including a base in a fixed position relative to the patient. A first portion has an arc member and is pivotally mounted on the base around a first axis (A1). A second portion includes a support member and a carrier member. The support member partially rotates around a second axis (A2). A third portion includes a holding member, and a sliding member mounted on the support member along a translation axis (AT). The holding member is arranged so that translation of the sliding member causes the intervention device to translate along a third axis (A3). The third axis (A3) is parallel to and offset from the translation axis (AT). When the carrier member is positioned halfway of the arc member, the first (A1), second (A2) and third (A3) axes are orthogonal.Type: GrantFiled: October 14, 2014Date of Patent: May 5, 2020Assignee: US Patent Innovations, LLCInventors: Clement Vidal, Berengere Bardou

Patent number: 10623861Abstract: A wearable device including a body having one or more embedded electronic components, the body further including a thermoset material having a polymeric backbone with at least one urethane linkage and a glass transition temperature. At a first temperature that is lower than the glass transition temperature, the body has an original shape. When the body is heated to a second temperature that is higher than the glass transition temperature, the body is deformable from the original shape to a first shape and when the body is cooled to a third temperature that is lower than the glass transition temperature, the first shape is maintained. The body is further configured to transition from the first shape to the original shape when the body is heated from the third temperature to a fourth temperature that is higher than the glass transition temperature.Type: GrantFiled: August 31, 2018Date of Patent: April 14, 2020Assignee: Bose CorporationInventors: Shawn Prevoir, Kai Gao

Patent number: 10617402Abstract: Methods and tool kits for implanting a lead subcutaneously. Examples include tool kits and methods for establishing first and second subcutaneous tunnels at an angle relative to one another to facilitate introduction of a lead to the subcutaneous space. In an example, a first insertion tool is used to establish a first subcutaneous tunnel, and a second insertion tool, with or without the use of a blunt dissector, sheath, guidewire, or steering mechanism, is used to initiate or form the second subcutaneous tunnel. Such methods and tool kits may reduce the number of incisions needed to implant a subcutaneous lead along a subcutaneous path having a curve therein.Type: GrantFiled: July 13, 2016Date of Patent: April 14, 2020Assignee: CAMERON HEALTH, INC.Inventors: G. Shantanu Reddy, Bruce A. Tockman

Patent number: 10603486Abstract: Methods for fabricating implantable cuff electrodes for contacting or at least partially surrounding internal body tissue such as, e.g., nerves, smooth muscles, striated muscles, arteries, veins, ligamental tissues, connective tissues, cartilage tissues, bones, or other similar body tissues, structures and organs are disclosed. An example method includes preparing a substrate including an implantable cuff electrode shape, applying a mold material to the substrate, curing the mold material to form a mold, releasing the mold from the substrate, inserting at least one conductor into the mold that penetrates through the channel of the mold, pressing a formable material into the channel of the mold to form a body of an implantable cuff electrode about the at least one conductor, curing the body of the implantable cuff electrode, and releasing the body of the implantable cuff electrode from the mold.Type: GrantFiled: June 12, 2017Date of Patent: March 31, 2020Assignee: GALVANI BIOELECTRONICS LIMITEDInventors: Dwight Sherod Walker, Daniel John Chew

Patent number: 10532205Abstract: A lead fixation accessory configured to be positioned over a skull hole and to transition between an opened state and a closed state during a lead implant procedure protects against lead migration by providing a mechanism for securing the lead in place at the skull hole while a stylet is removed from the lead. The lead fixation accessory remains in place after the implant procedure to provide chronic lead stability. A lead stabilization tool configured to access and grip a lead through a slotted cannula during the lead implant procedure also protects against lead migration by providing a mechanism for securing the lead in place at a point where the lead exits the skull hole while the slotted cannula is removed from the skull hole and peeled away from the lead.Type: GrantFiled: September 29, 2017Date of Patent: January 14, 2020Assignee: NeuroPace, Inc.Inventors: Jacob A.

Patent number: 10492882Abstract: Stereotactic systems and implantation methods that can be designed for use with a specific species and further customized for use with an individual within the species are provided. The stereotactic system can include an implant jig that can model a tissue or organ in which a target tissue area is located. A neurocap can be coupled to the implant jig for pre-planning and pre-placement of implants. A stencil can be used to determine the location for placement of the neurocap on the individual, so that the implants can be precisely targeted at the desired location. Pre-surgical information and data can be obtained from an individual and used to customize components of a stereotactic system, which can improve accuracy of implant placement.Type: GrantFiled: June 13, 2017Date of Patent: December 3, 2019Assignees: The Florida International University Board of Trustees, The Regents of the University of CaliforniaInventors: Timothy Allen, Bruce McNaughton, Meifung Su, Leila Mangan Allen
