    Abstract: A method of making a multi-lumen catheter may include disposing an outer surface of a mandrel against an outer surface of a first catheter; disposing a first heat shrink material around the first catheter and the mandrel; heating the first catheter and the mandrel to form a U-shaped channel along the outer surface of the first catheter; removing the first heat shrink material and the mandrel from the first catheter; placing a second catheter into the U-shaped channel; disposing a second heat shrink material around the first catheter and the second catheter such that the second catheter is retained within the U-shaped channel; and heating the first catheter and the second catheter to cause reflow between the first catheter and the second catheter to form the multi-lumen catheter.

    Abstract: A delivery catheter includes a soft, atraumatic distal tip. The distal tip is configured to transition from a folded configuration to an unfolded configuration during delivery of a medical device. A wall thickness of the distal tip may be increased such that the distal tip is biased to remain in the unfolded configuration after delivery. Additionally, the increased wall thickness in a selected region of the distal tip may cause the distal tip to resist and/or prevent collapse of the distal tip during retrieval and/or repositioning of the medical device when the medical device comes into contact with a distal end of the catheter. The distal edge of the distal tip may be rounded so as to prevent the distal tip from damaging tissue during advancement of the catheter to a target location within a patient's body.

    Abstract: A guide catheter may include a tubular member having an inner layer defining a lumen extending therethrough, a reinforcing braid disposed about the inner layer, a plurality of steering wires interwoven through the reinforcing braid, and an outer layer disposed about the reinforcing braid. At least a portion of the reinforcing braid may be embedded within the outer layer. An introducer sleeve may be slidably disposed over the tubular member. A flush port element may be operably connected to the introducer sleeve.
