Abstract
A modular tunneled catheter is provided that allows lumen length and cuff positioning to be adjusted based on the size of a patient. This catheter should be useful for any patient who would benefit from customized fitting of a catheter to their measurements. Methods of using the modular catheter for hemodialysis, peritoneal dialysis, and fluid drainage, including drainage of plural effusions from the lungs or malignant ascites from the abdomen are also described.
Claims33
An adjustable cuff comprising:
- a) a cuff body comprising a cylindrical surface with a slit, said cuff body having grooved edges on either side of the slit, wherein the cuff body fits around a catheter lumen and is slidable along the catheter lumen to allow custom positioning of the adjustable cuff along the catheter lumen when the cuff is unlocked;
- and
- b) a cuff key comprising projections that fit into the grooved edges at a complementary receiving location for the cuff key, wherein inserting the cuff key into the grooved edges at the receiving location locks the cuff and secures the cuff to the catheter lumen such that the cuff is no longer slidable along the catheter lumen.
An adjustable cuff comprising a clip body that can assume an open position or a closed position, said clip body further comprising a cuff material on the surface of the clip body with an adhesive-compatible surface, wherein the clip body comprises a first cuff piece and a second cuff piece, each cuff piece connected to a central hinge, wherein the first cuff piece and the second cuff piece can snap together around a catheter lumen to allow custom positioning of the adjustable cuff along the catheter lumen.
