An intercavity catheter having a distal end portion with serrations on the inner wall thereof.

Intercavity catheter

A cannula for insertion into a body incision is provided with a tip having an opening in the sidewall and a pair of recesses in the outer surface of the tip forming a longitudinally extending ridge on one side on the tip for facilitating the insertion of the tip into the incision and dilating the incision.

Medical tube device

A vena caval catheter is provided with a distal cage-like catheter tip having a cone connected to the inner side of the distal end of the tip within the cage and with the apex proximally of the distal end of the tip and coincident with the longitudinal axis of the catheter tip. The tip has a distal end and struts having smoothly contoured surfaces.

Vena caval catheter

An intercostal catheter is provided which, when the distal end is flattened for insertion into an incision of a patient from the exterior, has a distal end that is smooth and substantially free of deleterious protuberances to minimize damage the patient. A method of making an intercostal catheter is provided that includes the steps of severing tubing at an acute angle to its longitudinal axis, and displacing a portion of the proximal extremity of the end wall of the severed end to prevent the occurrence of a protuberance when the tube end is flattened for insertion.
