  • Patent number: 10912568
    Abstract: The balloon includes a pouch formed of a sealed wall delimiting an internal space, and a valve for filling the internal space with a fluid, capable of being occluded after filling the internal space. The pouch delimits a fluid-draining orifice opening into the internal space. The balloon further includes an occluding ball that occludes the draining orifice. The occluding ball can be spherical or polyhedral, and be capable of releasing the draining orifice under the effect of a magnetic field, so as to enable the at least partial drainage of the fluid contained in the internal space. The occluding ball is movable along at least two distinct axes in relation to the pouch.

  • Patent number: 10898310
    Abstract: A device and method for delivering a synthetic mesh or graft for anatomical repair at a defect site. A plurality of flexible arms is connected to the synthetic mesh or graft. Grasping jaws are individually controlled at or near a proximal end of the device for connection of the graft and release of the graft at the surgical site. The flexible arms, with graft attached are positioned through a surgical incision to the defect site. An actuator positions the flexible arms to assume a radial array at the surgical site, unfolding and spreading the graft for attachment. The length of each flexible arm is individually adjustable to adapt to the size and shape of the graft selected for installation at the defect site to repair the defect.

  • Patent number: 10898218
    Abstract: A tissue resecting device includes a handpiece assembly and an end effector assembly. The handpiece assembly includes a motor and a cooling assembly. The cooling assembly includes a housing, a fan assembly, and a fin pack. The fan assembly includes a tubular member configured to be received in the elongate cover, and a plurality of blades rotatably supported on the tubular member and operatively coupled with a drive rotor of the motor for concomitant rotation therewith. The fin pack includes a tubular base and a plurality of fins extending radially outward from the tubular base. The tubular base is disposed within the elongate cover and about the tubular member of the fan assembly. Actuation of the motor rotates the plurality of blades of the fan assembly to thereby advance air through a space between the fin pack and the elongate cover of the housing to facilitate cooling of the motor.

  • Patent number: 10893882
    Abstract: An atherectomy system includes a handle and a drive motor that is adapted to rotate a drive cable extending through the handle and operably coupled to an atherectomy burr. A control system is adapted to regulate operation of the drive motor, including providing the drive motor with a high frequency pulse width modulation (PWM) drive signal in order to operate the drive motor. The control system monitors a motor performance parameter such as motor speed or motor torque, and when the motor performance parameter approaches a limit of a performance range, the control system adds a low frequency PWM signal to the high frequency PWM drive signal, thereby causing the drive motor to produce a tactile signal that signals to the user that the motor performance parameter is approaching the limit of the performance range.

  • Patent number: 10874412
    Abstract: A surgical instrument apparatus includes an elongate tubular body having a proximal end and a distal end and a bore extending through the tubular body; an actuator link extending through and configured to move longitudinally within the bore, the actuator link including a first end connected to a first actuator at the proximal end of the tubular body and a second end terminating in a coupler, wherein the first end of the first actuator causes the actuator link to selectively move between an extended state and a retracted state.

  • Patent number: 10820848
    Abstract: An improved disposable puncture depth adjustable safety lancet includes a shell, a lancet core, a spring, and a trigger. The shell has an adjusting ring at a front end thereof to adjust a puncture depth, the adjusting ring being sleeved and clearance-fit at an outside of the trigger head. The adjusting ring and the shell are rotationally connected in a peripheral direction and are fixedly connected in an axial direction, and a rotational locating structure is formed by the adjusting ring and the shell in the peripheral direction. The adjusting ring has an inner wall equipped with a rotating step face or rotating bevel, and rotating the adjusting ring locates the adjusting ring in different locating positions. The rotating step face or rotating bevel is configured to meet the collision face of the lancet core in different axial positions, thereby changing the puncture depth of needle tip.

  • Patent number: 10779839
    Abstract: An end effector for a surgical clip applier includes a housing, and jaws that extend past a distal end of the housing and include opposed first and second jaw members each comprising an independent structure movable relative to the other. The first jaw member defines a first inner surface and the second jaw member defines a second inner surface opposite the first inner surface. An actuation mechanism is operatively coupled to the jaw members and operable to move the jaws between an open position and a closed position. The first and second inner surfaces remain substantially parallel to each other as the jaws move between the open and closed positions.

  • Patent number: 10639152
    Abstract: Disclosed herein are expandable introducer sheaths and methods of making and using the same. The sheaths minimize trauma to a patient's vasculature by allowing for temporary expansion of a portion of the sheath to accommodate passage of a delivery system for an implant, then return to a non-expanded state after the passage of the device. The sheath includes a foldable inner member having a detached flap structure at its distal tip that facilitates expansion of the sheath lumen to increased diameters, and an elastomeric distal end that reduces push and retrieval forces therethrough. The sheath can include a hemostasis seal on its proximal end to prevent the leakage of blood out of the sheath and prevent ballooning of outer layer of the sheath.

  • Patent number: 10575843
    Abstract: A suture anchor for deployment in a preformed bone hole to secure soft tissue to bone. The anchor includes a proximal part, a distal part, an inner tube part and a ring part. The ring part is configured to move independently relative to the proximal part, inner tube part and distal part and further comprises two pairs of opposing apertures defining two suture passageways between an outer surface of the inner tube part and inner surface of the ring part. Before or after being connected to soft tissue, a suture is directed through the two suture passageways. Tension on the tissue can be adjusted by maneuvering the suture in the ring part without interfering with advancement of the distal part into the bone. The anchor has a center bore extending longitudinally between a distal end and proximal end of the anchor and is configured to receive an insertion guide.
