Patent number: 11241214Abstract: An apparatus for the ultrasound guided refilling of a drug delivery pump includes an ultrasound imaging transducer having a nosepiece and a support device coupled to the nosepiece of the ultrasound imaging transducer. The support device can have two support holes whose centers are positioned along a horizontal axis of the support device. A marker can be placed in each of the two support holes. The vertical axis of the ultrasound imaging transducer coincides with the vertical axis of the support device. When imaging using this apparatus and the port inlet of the pump is visualized using the ultrasound transducer, two primary marks on skin can be created by inserting a marker into the support holes. The apparatus can then be rotated around its vertical axis, and a marker again inserted into the support holes to create two secondary marks. The inlet port of the pump is then marked at the intersection of lines which connects the primary marks and respectively the secondary marks.Type: GrantFiled: August 28, 2018Date of Patent: February 8, 2022Assignee: Clarius Mobile Health Corp.Inventor: David Glenn Willis

Patent number: 11234770Abstract: Systems and methods for femoral medial condyle spherical center identification and tracking are described herein. Once the spherical center of the medial condyle is identified, the spherical center is tracked using a pin or internal reference. The spherical center may be used to provide a key kinematic motion reference, such as when the medial condyle is adjusted during a surgical procedure. The tracking may be used to provide optical tracking, inertial tracking, or other tracking. In contrast with surface-mounted optical trackers, the spherical center tracking is not lost during resection (e.g., removal) of a bone surface. Tracking the medial condyle spherical center may reduce or eliminate the need for a surface-mounted optical tracker or preoperative 3-D modeling or of the joint.Type: GrantFiled: September 12, 2018Date of Patent: February 1, 2022Assignee: Biomet Manufacturing, LLCInventors: Michael E. Berend, Pierre Couture

Patent number: 11234612Abstract: A medical device can be localized by providing at least three non-colinear localization elements (e.g., electrodes) thereon. Once placed in a non-ionizing localization field, three adjacent localization elements, at least one of which will typically be a spot electrode, may be selected, and the non-ionizing localization field may be used to measure their locations. A cylinder is defined to fit the measured locations of the selected localization elements. The cylinder is rotationally oriented using the measured location of a spot electrode. Location and rotational attitude information may be used to construct a three-dimensional representation of the medical device within the localization field. The electrodes may be provided on the medical device or on a sheath into which the medical device is inserted. The invention also provides systems and methods for identifying and calibrating deflection planes where the medical device and/or sheath are deflectable.Type: GrantFiled: October 4, 2017Date of Patent: February 1, 2022Assignee: ST JUDE MEDICAL, ATRIAL FIBRILLATION DIVISION, INC.Inventors: John Anderson Hauck, Lubomir Velitchkov Dragnev, Don Curtis Deno, Eric John Wilkowske
