摘要： A feeding tube for insertion into the jejunum of a patient. An elongated tubular member has a proximal portion, a distal portion, a lumen extending between the proximal and distal portions, and at least one aperture at the distal portion. The aperture is sized for passage of fluid material from the lumen into the jejunum. An inflatable balloon is disposed about a length of the elongated tubular member distal portion. The balloon is sized and configured such that upon inflation via water or saline inflation media, the balloon projects outwardly from the tubular member distal portion so as to be engageable with an interior wall of the body passageway. An echogenic material is disposed along the tubular member distal portion in conjunction with the balloon to provide an echogenic capability, so that the tubular member length is visible under ultrasound imaging.

摘要： A catheter assembly for use in extracorporeal treatment of a body fluid comprises a catheter body having a plurality of lumens extending therein. The catheter body has an aspiration port in communication with a first lumen for transporting fluid withdrawn from a body vessel to a treatment instrument, such as a dialyzer, and an infusion port in communication with a second lumen for return of treated fluid to the vessel. The catheter body includes a wing-like flap portion extending radially from the catheter body and defining the aspiration port. The flap portion is configured and arranged to space the aspiration port from a wall of the body vessel.

摘要： A multi-lumen catheter assembly for use in the extracorporeal treatment of a body fluid of a patient. The catheter assembly includes an elongated catheter body having a pair of lumens extending therethrough, and a septum separating the lumens. The catheter body has an aspiration port in communication with a first lumen for transporting fluid withdrawn from a body vessel to a treatment unit, and an infusion port in communication with a second lumen for return of treated fluid to the vessel. The infusion port is positioned distal of the aspiration port along a length of the catheter body. A flexible member is provided, wherein the flexible member has an end receivable in the first lumen and another end engaged with the catheter body distal of the aspiration port. The flexible member is structured and arranged to maintain a spacing between the aspiration port and a wall of the vessel.

摘要： A catheter having a selectively variable degree of flexibility includes an elongate tubular outer member and an elongate tubular inner member disposed within the outer member. The catheter further includes a cavity disposed in between the outer and inner members. A tubular braid of filaments may be disposed within the cavity. The outer and inner members are movable relative to each other along intermediate portions thereof when in a first configuration, and are not movable relative to each other when in a second configuration. When the inner and outer members are in the first configuration, the tubular braid of filaments is movably disposed relative to at least one of the outer member and the inner member. When the inner and outer members are in the second configuration, the inner and outer members clamp the tubular braid of filaments in a fixed position relative to the inner and outer members.
