  • Patent number: 11259797
    Abstract: Systems, devices and methods to improve safety and efficiency in an operating room comprise providing a suture package that holds new suture needles and needle receptacles for storing used needles. The devices can be safely worn for the surgeon to self-dispense new suture needles in the near surgical field and to secure the used needles into a needle trap or a needle retainer located on his extremity, on his operative instruments or on the surgical drapes. The device may provide automated and/or simplified needle counting both during use and after removal from the surgical field. The device may be configured for ergonomic and efficient use so as to minimize the actions and motions of the surgeon to dispense and secure the needle.

  • Patent number: 11259834
    Abstract: A medical device for treating an aneurysm in a blood vessel includes a hollow shaft for insertion into the blood vessel, an exit port at a distal end of the shaft, a deflection element, and a position sensor. The hollow shaft encompasses a wire-insertion channel for leading a wire to be inserted into the aneurysm. The exit port is configured for exiting the wire from the wire-insertion channel and into the aneurysm. The deflection element is located adjacent to the exit port and configured to deflect the wire from the wire-insertion channel to the exit port. The position sensor, which is coupled to the distal end of the shaft, is configured to produce signals indicative of a position and orientation of the exit port in the blood vessel.

  • Patent number: 11259838
    Abstract: Disclosed is a system and method for the placement of elongate medical members within a patients body using coaptive ultrasound. In a particularly preferred embodiment, a flexible tube includes a first balloon at a distal end of the tube, and a second balloon at the distal end of the tube and positioned within the first balloon. The first and second balloons are inflatable to form one or more echogenic windows between them, which echogenic window may be detected from within a patient's body by an ultrasound probe that is external to the patient's body. Detection of such echogenic window is used to identify an acceptable location on the patient's body at which to insert a guidewire configured to receive an elongate medical member without damage to surrounding patient tissues or organs.

  • Patent number: 11259842
    Abstract: The present disclosure relates to a needle including a wall structure, a cutting edge and a blunt contour. The needle advantageously can be used to deliver a sensor (such as a glucose or other analyte sensor) through an outer skin layer and into a sensor depth in a less invasive way than prior art needles. The size of the cutting edge is balanced against a portion of the distal wall structure that has blunt contours. Thus, the needle is capable of cutting the more durable outer skin layer (first phase) and then progressively stretching open the cut for further advancement into the subcutaneous layer (second phase). When the needle is sufficiently advanced, it is retracted leaving the sensor in a desired position. Early testing has shown a reduction of “dip and recover” from glucose sensors delivered using the needle.
