Publication number: 20240102560Abstract: A valve may have a fluid inlet and a fluid outlet. The valve may include a valve stem having a lumen extending from a first opening at a proximal portion of the valve stem to a second opening at a distal end of the valve stem. A plurality of seals may be positioned relative to the valve stem. The valve stem and seals may be configured so that a fluid entering the inlet is prevented from flowing to the outlet in a first position of the valve stem and relative to the inlet and the outlet. The valve stem and the seals may be configured so that a fluid entering the inlet flows to the outlet in a second position of the valve stem relative to the inlet and the outlet, the second position being more distal than the first position relative to the inlet and the outlet.Type: ApplicationFiled: December 6, 2023Publication date: March 28, 2024Applicant: Boston Scientific Scimed, Inc.Inventors: Larry STANTON, Allyn JENSRUD, James SCUTTI, Colby HARRIS, Robb GAVALIS

Patent number: 11707229Abstract: A sensor for a medical device including a plurality of sensor segments. Each of the plurality of sensor segments can include a layer of magnetically-permeable material and a layer of electrically-conductive material disposed on the layer of magnetically-permeable material. In an example, the layer of magnetically-permeable material can be arranged in a partially-annular shape. The sensor segments can include an electrical connection formation that extends transverse to the layers of magnetically-permeable material and electrically-conductive material. The electrical connection formation can be electrically coupled with the layer of electrically-conductive material. The plurality of sensor segments can be electrically coupled with each other through an electrical coupling of the respective layer of electrically-conductive material of each sensor segment with the electrical connection formation of another sensor segment.Type: GrantFiled: March 8, 2021Date of Patent: July 25, 2023Assignee: St Jude Medical International Holding S.À R.L.Inventors: Terry Sterrett, Allyn Jensrud
