  • Patent number: 11065431
    Abstract: Capping and cleansing devices for capping and cleansing needlefree connectors, particularly luer access devices such as needlefree vascular access connectors, and methods for using said devices, are described. The devices of the invention each include interconnected inner and outer housings that a user can transition between a locked or engaged position to allow the inner and outer housings to rotate in unison and an unlocked or disengaged position that allows the outer housing to rotate independently of the inner housing, and a compressible cleansing matrix secured in the devices (preferably in a well in the outer housing).

  • Publication number: 20210186538
    Abstract: Devices for loading intravascular treatment devices into a sheath and associated systems and methods are disclosed herein. A sheathing tool may include, for example, a first channel extending to a first opening, the first channel configured to receive a treatment device in a constrained state therethrough. The treatment device may include an elongated member and a first element and a second element at a distal region of the elongated member. The second channel may extend to a second opening, the second opening surrounded by a sidewall and configured to receive the treatment device in the constrained state therethrough, wherein the second opening is spaced apart from the first opening by a gap, and wherein a length of the gap is great enough to allow the first element to self-expand over the sidewall while the second element generally maintains its diameter in the constrained state while crossing the gap.

  • Publication number: 20210069409
    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.

  • Publication number: 20210038943
    Abstract: A method of exercising includes positioning a foot of a user onto a pedal of an exercise device. The pedal is pivotably connected to a pair of supports forming a triangular base and has a neutral position relative to a pivot axis of the device. The method includes applying a first force to the pedal to rotate the pedal about the pivot axis in a first direction, toward a first support. The method includes resisting movement of the pedal toward the first support with a resistance mechanism of the device. The method includes applying a second force to the pedal to rotate the pedal about the pivot axis in a second direction, opposite the first direction, toward a second support and away from the first support. The method includes resisting movement of the pedal toward the second support with the resistance mechanism of the device.

  • Publication number: 20200406093
    Abstract: An exercise device includes a foot support portion pivotably connected to a leg support portion and having a neutral position relative to a pivot axis. The support portion is configured to rotate about the neutral pivot axis in a first direction away from the neutral position and in a second direction away from the neutral position. The second direction is opposite the first direction. The exercise device also includes a resistance mechanism configured to exert a force on the foot support portion about the pivot axis opposite to the respective first and second directions of rotation of the foot support portion about the pivot axis.

  • Publication number: 20200376324
    Abstract: Disclosed is a technical training garment configured for use with modular, interchangeable electronics and resistance modules. The garment provides resistance to movement throughout an angular range of motion and tracks biomechanical parameters such as stride length, stride rate, angular velocity and incremental power expended by the wearer. The garment may be low profile, and worn by a wearer as a primary garment or beneath or over conventional clothing. Alternatively, the device may be worn as a supplemental training tool during conventional training protocols.

  • Publication number: 20200269016
    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.

  • Patent number: 10702740
    Abstract: A portable exercise device includes a pedal pivotably connected to a pair of supports. The pedal has a neutral position relative to a pivot axis. The pedal is configured to rotate about the pivot axis in a first direction toward one support and in a second direction, opposite the first direction, toward the other support. The exercise device also includes a resistance mechanism configured to exert a force on the pedal about the pivot axis in a direction opposite to the respective direction of rotation of the pedal about the pivot axis. The device is movable between an open, in-use configuration, where the pedal is disposed in the neutral position to receive a foot of a user and the pair of supports together form a triangular base, and a closed configuration, where the pair of supports are flush against the pedal.

  • Patent number: 10702397
    Abstract: An insertion handle for medical implants includes a handle with an elongate shaft extending therefrom and connection means for the implant disposed at the end of the shaft opposite the handle. The connection means includes a pivotable attachment for the implant that is controlled remotely from the handle. Both angle of the implant with respect to the handle and shaft as well as the attachment may be separately controlled and adjusted. Remote angular adjustment facilitates insertion of implants in to small surgical sites because the orientation of the implant may be repeatedly, remotely adjusted as the implant is inserted. Connectors may also be provided at the engagement surface between the handle and implant in order to provide communication with the implant or surgical site. The connectors also may serve as torque bearing members to avoid the need for separate torque bearing means such as keyways and the like.

  • Publication number: 20200086170
    Abstract: A portable exercise device includes a first body and a second body. The exercise device also includes a support structure pivotably connecting the first and second bodies. The support structure is configured to move between an engaged position and a disengaged position. The device also includes a resistance mechanism configured to resist movement of the first and second bodies toward one another when the support structure is in the engaged position. When the support structure is in the engaged position, the first body is positioned substantially parallel to the second body such that in a first open, in-use configuration of the device, the first body has a first neutral position relative to a pivot axis and in a second open, in-use configuration of the device, the second body has a second neutral position relative to the pivot axis.
