摘要: A loading dilator (10) introducing a tracheostomy tube (100) into a stoma (140) formed in an outer body wall of a patient includes a handle (12) and a tubular portion (14) received in a distal opening (61) of the handle. The tubular portion includes a radially outer dilator member (20), and a radially inner actuation member (32) substantially spanning the length of the tubular portion. A radially intermediate segment has a conical member (26) at a tapered distal end of the tubular portion, a compressible member (30) positioned proximal of the conical member, and an elongated tubular member (40) proximal of the compressible member. The conical member is engaged with the inner actuation member such that the conical member and inner actuation member are proximally movable relative to the elongated tubular member, whereby the compressible member is deformable from a smaller diameter to a larger diameter for facilitating entry into the stoma of a medical apparatus. The handle has a trigger (80) operatively engaged with the inner actuation member for effecting proximal movement of the inner actuation member and conical portion.

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 The catheter body has an aspiration port in communication with a first lumen for transporting fluid withdrawn from a body vessel to a treatment unit, and an infusion port in communication with a second lumen for return of treated fluid to the vessel.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.
