  • Patent number: 11006993
    Abstract: An inflatable bone tamp for performing a minimally invasive surgical procedure includes an outer shaft defining an internal lumen, an inflatable structure coupled to the outer shaft, and an inner shaft movably disposed within the internal lumen and coupled to a distal end region of the inflatable structure. The internal lumen is sized to receive the inflatable structure, such that by moving the inner shaft relative to the outer shaft, the inflatable structure can be retracted into the internal lumen (and likewise can be extended from within the internal lumen for deployment in bone). This retraction capability can beneficially protect the inflatable structure during positioning/removal, and can also enhance recovery from radial tears of the inflatable structure.

    Abstract: A self propelled, endoscopic apparatus formed of a flexible, fluid-filled toroid and a motorized or powerable frame The apparatus may be used to advance a variety of accessory devices into generally tubular spaces and environments for medical and non-medical applications. The apparatus when inserted into a tubular space or environment, such as the colon of a patient undergoing a colonoscopy, is advanced by the motion of the toroid. The toroid's surface circulates around itself in a continuous motion from inside its central cavity along its central axis to the outside where its surface travels in the opposite direction until it again rotates into its central cavity. As the device advances within the varying sizes, shapes and contours of body lumens, the toroid compresses and expands to accommodate and navigate the environment. The motion of the toroid can be powered or unpowered and the direction and speed may be controlled.

  • Publication number: 20120150110
    Abstract: A system for providing access across a site of obstruction is provided. The system may include a sleeve, having a distal portion that can move from an inverted position to an everted position. A balloon situated within the sleeve can be extended so as to evert sleeve. A pathway can extend across a juncture between the distal portion and the remaining portion of the sleeve so as to provide access across the site of obstruction. A method for providing access across the site of obstruction is also provided.

  • Patent number: 7967798
    Abstract: Disclosed is an introducer apparatus comprising an sleeve fixation mechanism or introducer member, such as a catheter, introducer, or ring-like structure, which is attached to a protective sleeve comprising a thin flexible material such a polymeric film. The sleeve is inverted into the passageway of a second member, such as a catheter, feeding tube, introducer, etc., that is advanced through the passageway of the introducer member and is introduced into a bodily passage of a patient, such as the bile duct, nasal passages, colon, etc. The sleeve everts from the passageway of the second member during its advancement to lay down a friction-reducing surface. The sleeve prevents frictional contact between the second member and delicate or sensitive tissues.

  • Patent number: 7922687
    Abstract: A catheter assembly for use in the extracorporeal treatment of bodily fluids. The assembly comprises a catheter body having a withdrawal port, an infusion port, and a plurality of lumens therein. One of the lumens comprises a withdrawal lumen for transport of fluids withdrawn from a body vessel through the withdrawal port to an extracorporeal treatment unit, such as a dialyzer. Another lumen comprises an infusion lumen for return of treated fluids from the extracorporeal treatment unit into the body vessel through the infusion port. A wire extends from yet another lumen to an attachment point on the catheter assembly. The wire is capable of bowing radially outwardly from the catheter body, in order to space the infusion and withdrawal ports from the vessel wall.

  • Patent number: 7749185
    Abstract: A method for inserting a multi-lumen catheter into a patient is disclosed. The catheter includes an elongated, central, multi-lumen tube portion having a proximal end and a distal end. A distal branch portion includes a plurality of single-lumen distal extension tubes. The proximal first end of each distal extension tube is connected to the distal end of the central tube portion such that the single lumen of each distal extension tube is in fluid communication with one of the plurality of lumens of the central tube portion. A proximal branch portion includes a plurality of single-lumen proximal extension tubes. The distal first end of each proximal extension tube is connected to the proximal end of the central tube portion such that the single lumen of each distal extension tube is in fluid communication with one of the plurality of lumens of the central tube portion.

  • Publication number: 20090137970
    Abstract: Universal laparoscopic uterine manipulators/dilators with variable intra-uterine length to match the length of the uterus in order to avoid any risk of perforation and to provide excellent pelvic exposure irrespective of uterine size, shape and position. Moreover, semirigid/semi-flexible dilators are less likely to form false passages in the cervix and the body of the uterus as they follow the natural track of the cervical canal.

  • Publication number: 20080167629
    Abstract: Disclosed herein are elongate flexible medical devices which are capable of axial elongation through the mechanism of eversion or toposcopic expansion. In general, this may be accomplished by providing a flexible tubular device having a proximal end and a distal end. Retraction of the distal end in a proximal direction through the tubular body inverts the tube upon itself, causing an axial shortening of the overall length of the device. The original length of the device can be restored by coupling a pressurized media to the proximal end of the sleeve. If the distal end of the sleeve is temporarily restricted or closed, the pressurized media causes the distal end of the sleeve to travel distally until the full length of the sleeve has been restored.
