  • Patent number: 11730884
    Abstract: An implantable externally driven fluid delivery system for localized delivery of medical agents and drugs, such as antibiotics, may be provided herein. The fluid delivery system includes a housing that incorporates a filling septum connected to a flexible internal reservoir. The reservoir is connected to a miniature diaphragm pump with coupled magnetic components. The entire fluid delivery system is implantable into a body cavity or surgically formed location that provides for local medical agent delivery. The reservoir is filled via percutaneous injection through the skin into the septum. Fluid delivery is achieved through proximity of the external controller that generates an oscillating or reversing magnetic field suitable to actuate the pump's diaphragm resulting in controlled fluid flow. Once local drug delivery treatment is complete, the controller can be discarded.

  • Patent number: 11590391
    Abstract: A method for exercising muscles in an ankle, foot, and/or leg of a user includes positioning a foot of a user onto a first body of an exercise device. The first body is spaced away from a second body of the device and pivotably connected to the second body of the device at a pivot axis. The pivot axis is adjacent to a central portion of the first body. The method includes rotating the first body about the pivot axis, with the foot, against a first resistive force. Rotating the first body includes subjecting the foot to a first motion. The method includes positioning the foot onto the second body. The method includes rotating the second body about the pivot axis, with the foot, against a second resistive force. Rotating the second body includes subjecting the foot to a second motion, the second motion being different than the first motion.

  • Patent number: 11484689
    Abstract: A medical device delivery system can be used to advance a medical device to a target area within a patient's vasculature. The system can comprise a catheter, a support sheath, and a core member coupled to a medical device. The core member can be used to longitudinally advanced or retracting medical device within a lumen of the support sheath. The support sheath can be advanced within the catheter until a distal end of the support sheath contacts or abuts a reduced diameter section of the catheter lumen. Thereafter, the core member can be advanced into the catheter lumen toward the target area.
