  • Patent number: 10772600
    Abstract: An interventional medical device is provided that incorporates a forward-directed ultrasound or optical coherence tomography imaging system that is replaceable depending on how close the device is to the target site for a given medical procedure, the device and system integrated into a single minimally invasive device comprising a first probe housing, needle guide assembly and sheath, a sleeve lock for closing a normally open needle channel of a needle guide of the first distal assembly and a second probe and cable housing assembly locked to the first distal probe housing, needle guide assembly and sheath by a locking tab. The probe and cable housing assembly may comprise a linear phased ultrasound array and an accelerometer for orienting an image produced by the device with the gravitational field of the earth. The medical device can be in the form of an image guided catheter or probe, used in a body orifice, externally on skin tissue or subcutaneously.

  • Patent number: 10765845
    Abstract: A medical tube 10 (drain tube 10) includes a main shaft tube 20, a flow path opening/closing mechanism 40, and a branch tube 30. The main shaft tube 20 internally has a main shaft side distal opening 21a and a main shaft lumen 21. The flow path opening/closing mechanism 40 brings the main shaft lumen 21 into a communicating state by applying pressure smaller than predetermined pressure, and brings the main shaft lumen 21 into a blocked state by applying pressure equal to or greater than the predetermined pressure. The branch tube 30 promotes a pancreatic juice pj to flow into a branch lumen 31, based on the applied pressure which is equal to or greater than the predetermined pressure.

  • Patent number: 10758421
    Abstract: The purpose of the “Dissolvable on-command Implant” is to act as a pressure equalizer tube in the eardrum, which has the unique characteristic that the tube can be dissolved with a specially formulated drop solution on-command. This tube can have various shapes and sizes, although the tube is usually a cylindrical tube with a hollow center, which maintains a ventilatory port for the middle ear space. With this design, the ear tube promotes drainage of middle ear fluid, lets air enter the middle ear, and allows for instillation of antibiotic drops.

  • Patent number: 10751054
    Abstract: An end effector includes first and second jaws, a drive screw, a lead screw nut, and a drive beam. The drive screw is disposed within the first jaw. The lead screw nut defines a threaded bore that receives the drive screw. The lead screw nut is advanced along the drive screw as the drive screw is rotated in a first direction and is retracted along the drive screw as the drive screw rotates in a second direction. The drive beam is releasably coupled to the lead screw nut when the lead screw nut is in a retracted position. As the lead screw nut is advanced the drive beam is pulled by the lead screw nut. The drive beam is decoupled from the lead screw nut as the lead screw nut is advanced such that the lead screw nut is advanced relative to the drive beam.

  • Patent number: 10695073
    Abstract: A rotary, cutting medical device configured to be used during surgeries, such as ACL reconstruction, to drill holes and retrograde sockets is disclosed. The device may include a blade at a distal end that is movable between a first position aligned with a longitudinal axis of the device and a second position nonparallel to the longitudinal axis used to create retrograde sockets. The device may include a blade position control system connecting the blade to distal ends of both the outer tube and inner shaft and configured to control movement of the blade between first and second positions for drilling a hole and then creating a retrograde socket. The device may include a position retention system configured to retain the blade in the second position while allowing the inner shaft and blade to rotate to cut the socket.

  • Patent number: 10695535
    Abstract: A catheter for ablation, mapping, injection, and directional control by an external magnetic system has a catheter body, an intermediate section, and a tip section having a tip electrode with an omnidirectional distal end and a concentric needle port. The tip electrode houses a magnetic device and a position sensor in an integrated configuration that facilitates a path in the tip section for extension and retraction of a component, including an injection needle, with reduced stress and friction. The integrated configuration is an efficient use of space in the tip electrode that allows the tip section to carry both the position sensor and the necessary volume of magnetic or magnetizable material to accomplish magnetic navigation. The catheter also includes a very soft and flexible intermediate section and an even softer and more flexible distal transitional section carrying additional magnetic members to facilitate remote magnetic navigation.

  • Patent number: 10667702
    Abstract: A coaxial dual lumen pigtail catheter utilizes coaxial construction incorporating a thin wall guiding catheter technology for the outer lumen and using a strong braided diagnostic technology for the central lumen to accommodate high-pressure injections. The catheter includes a manifold body to provide for connection to each of the dual lumens. The distal end of the coaxial dual lumen pigtail catheter tapers to a more flexible portion that is perforated by spiral side holes to provide for more undistorted pressure readings in the left ventricle. The coaxial dual lumen pigtail catheter also utilizes proximal straight sideholes at the end of the dual lumen portion and a taper between the dual lumen portion and the single lumen portion.
