A multi-lumen catheter defined by at least two separate tip sections distal to a dividing point includes strategic placement of openings in the tip sections to facilitate fluid flow and minimize typical problems associated with catheters. In a multi-lumen catheter having tip sections with a releasably joined or splittable region, the bond strength between the tip sections is varied along their length such that an increasing separation force is required to separate the tip sections from one another distal to the dividing point. Delivery of a multi-lumen catheter is improved with respect to both sheathed and non-sheathed delivery methods, in which a friction reducing structure is provided on either the catheter, delivery sheath or both to provide a buffer for a sheathed delivery and in which a unique guidewire aperture or additional lumen is provided in at least one of the tip sections for a non-sheathed delivery.
A multi-lumen catheter, comprising:
A multi-lumen catheter, comprising:
A delivery sheath for delivering a multi-lumen catheter to a body vessel, comprising at least one ridge positioned on an inside surface of said delivery sheath along an entire length thereof.
A multi-lumen catheter, comprising:
A method for producing a variable separation force between adjacent inner surfaces of at least two tip sections distal to a dividing point in a split-tip catheter, comprising the step of creating at least two fusion zones between said inner surfaces, each of said fusion zones having a different bond strength.
A multi-lumen catheter, comprising:
A multi-lumen catheter, comprising:
The multi-lumen catheter according to claim 1115, further comprising a second opening formed in said first tip section along said second edge, said second opening being positioned with at least a portion thereof though each of said first and second surfaces.
The multi-lumen catheter according to claim 1116, wherein said first and second openings are longitudinally offset from one another.
The multi-lumen catheter according to claim 1117, further comprising a third and fourth opening formed in said first tip section.
The multi-lumen catheter according to claim 1119, wherein each of said first, second, third and fourth openings are longitudinally offset from one another.
A multi-lumen catheter, comprising:
