  • 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: 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.

  • 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.

  • Publication number: 20200197686
    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 such devices, are described. The devices of the invention include interconnected inner and outer housings that a user can transition between a locked or engaged position to allow them to rotate in unison and a unlocked or disengaged position that allows the outer housing to rotate independently of the inner housing about the device's central axis, and a compressible cleansing matrix secured in the device (preferably in a well in the outer housing).

  • 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.

  • Publication number: 20190328544
    Abstract: A spinal implant which is configured to be deployed between adjacent vertebral bodies. The implant has at least one extendable support element with a retracted configuration to facilitate deployment of the implant and an extended configuration so as to expand the implant and effectively distract the disc space, stabilize the motion segments and eliminate pathologic spine motion. The implant has a minimal dimension in its unexpanded state that is smaller than the dimensions of the neuroforamen through which it typically passes to be deployed within the intervertebral space. The implant is provided with a locking system having a plurality of linked locking elements that work in unison to lock the implant in an extended configuration. Bone engaging anchors also may be provided to ensure secure positioning.

  • Patent number: 10457912
    Abstract: Disclosed herein are systems, devices and methods for processing tissue, such as autologous tissue. Implementations of a Stromal Vascular Fraction (SVF) system are described that can isolate and wash harvested cells contained within various tissues, such as isolate and wash stem cells from fat tissue. The SVF system can minimize the handling and transferring of tissue and fluids, including minimizing the number of human interventions and manipulations required throughout processing. The SVF system can ensure sterility of processed tissue and harvested cells, as well as significantly reduce cost and time associated with the processing.

  • Publication number: 20190083080
    Abstract: A joint balancing insert with sensors and an actuated mechanism is disclosed. The joint balancing insert is used to balance a joint during arthroplasty surgery, as the sensors provide force, position and angular data relating to the movement of the joint, while the actuated mechanism allows for highly accurate and dynamic adjustments of the joint based on the data from the sensors. Various configurations of actuated mechanisms and sensors may be implemented in the insert to provide for manual or real time control of the insert, and customized interfaces are provided for visualized feedback of adjustments. Sensor data may also be collected and compared with expected or preferred data sets to provide adjustment recommendations and achieve better outcomes based on historical data.

  • Publication number: 20190038873
    Abstract: A steering assembly for an intravascular catheter system includes first and second pull wires, a steering knob, and first and second movers. The intravascular catheter system includes a handle assembly having a longitudinal axis and a balloon catheter having a catheter shaft with a distal end. The first and second pull wires extend between the handle assembly and the distal end of the catheter shaft. The first mover includes a knob engager that engages an internal thread of the steering knob so that rotation of the steering knob about the longitudinal axis moves the first mover in a first direction. The second mover is coupled to the first mover so that the second mover moves in a second direction. Movement of the first and second movers moves the first and second pull wires to articulate a portion of the balloon catheter near the distal end of the catheter shaft.

  • Publication number: 20180353196
    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.
