  • Publication number: 20190167269
    Abstract: A plurality of structures that resiliently attract one another are provided for implanting in a patient around a body tissue structure of the patient. For example, the body tissue structure may be the esophagus, and the plurality of structures may be implanted in an annulus around the outside of the esophagus, the annulus being substantially coaxial with the esophagus. The attraction may be between annularly adjacent ones of the structures in the annulus, and it may be provided, for example, by magnets or springs. The array of structures is preferably self-limiting with respect to the smallest area that it can encompass, and this smallest area is preferably large enough to prevent the apparatus from applying excessive pressure to tissue passing through that area.

  • Publication number: 20140228677
    Abstract: A cytology sampling system includes a catheter tube and a cytology tool. The catheter tube has open proximal and distal ends. The cytology tool is insertable through the catheter tube and includes a flexible shaft, a brush, and a position sensor. The flexible shaft defines proximal and distal ends thereof. The brush is coupled to the distal end of the flexible shaft. The brush includes a plurality of brush shafts. Each brush shaft has bristles disposed along a portion of a length thereof. The bristles are coupled to and extend radially away from an outer surface of each of the brush shafts. The bristles are configured to collect cell samples from targeted tissue of a patient. The position sensor provides an indication of the location of the position sensor within a luminal structure. The system may include a positioning assembly for placing the distal end of the catheter tube adjacent the target tissue.

  • Patent number: 8715157
    Abstract: A structure that can be used as a gastric band (and that may also have other uses as an implant elsewhere in a patient) includes a plurality of magnetic elements in a serial array that can be implanted so that the array extends in a circumferential direction around the patient's stomach (or other body tissue structure in the patient). Circumferentially adjacent magnetic elements magnetically attract one another to apply radial pressure to the tissue structure encompassed by the array, but those elements can also move apart in response to sufficient outward pressure from the encompassed tissue structure and/or the contents of (e.g., food in) that tissue structure. When used as a gastric band, the device can provide resistance to excessive food intake, which can help promote weight loss.

  • Patent number: 8574264
    Abstract: A closure device for sealing a patent foramen ovale (PFO) in the heart includes a left atrial anchor adapted to be placed in a left atrium of the heart, a tether fixedly connected to the left atrial anchor and adapted to extend through the passageway of the PFO, a right atrial anchor adapted to be placed in a right atrium of the heart and moved along the tether, and a lock for securing the position of the right atrial anchor along the tether. The left and right atrial anchors preferably include a plurality of arms formed as loops and may include means for securing each arm in case of fracture in the loop. After the closure device is positioned, a cutting tool may sever the portion of the tether proximal of the right atrial anchor. The closure device can be retrieved during delivery, including by use of a snare catheter.

  • Patent number: 7976564
    Abstract: Devices and methods for sealing a passageway formed by a patent foramen ovale (PFO track) in the heart are provided. One method includes providing an abrading device to the PFO track and abrading the tissue within the PFO track. The abraded tissue forming the PFO track is then held together under pressure, either via lowering right atrial pressure or via applying suction to the septum primum to pull it into apposition against the septum secundum. After a sufficient period of time, the pressure is released and the abraded tissue heals to form a robust seal over the PFO track. Additionally, several devices are provided which can be placed into the PFO track to apply adhesive to the walls of the PFO track. The devices may or may not be left within the PFO track. If the devices are not left within the PFO track, the walls of the PFO track, covered with adhesive, are brought into apposition with one another and adhered together.

  • Patent number: 7891964
    Abstract: A pump system comprising a delivery assembly configured to feed a solid material under operational power of a first drive motor, and a screw pump comprising a housing that at least partially defines a barrel of the screw pump, an extrusion tip secured to the housing at a first end of the barrel, a liquefier secured to the housing and intersecting with the barrel, and an impeller extending at least partially through the barrel. The liquefier is configured to receive the solid material fed from the delivery assembly, to at least partially melt the received solid material, and to direct the at least partially melted material to the barrel, and the impeller is configured to drive the at least partially melted material that is directed to the barrel toward the extrusion tip under operational power of a second drive motor.

  • Patent number: 7445010
    Abstract: Plural (at least two) magnetic devices are implanted in a patient so that magnetic interaction between those devices modifies the patient's body in one or more respects (e.g., by modifying the shape and/or performance of some part of the body) Prior to implantation, a location in the body may be marked for later reference during the implantation. The magnetism of one or more of the magnetic devices may be changed in vivo after implantation. One or more of the implanted devices may be subsequently removed from the patient if desired. Use of the magnetic devices inside tissue conduits (e.g., as a treatment for GERD) is especially considered by way of illustration.
