Abstract
A microcatheter comprises a coil formed over an inner liner. The coil is covered with a series of outer jacket segments that decrease in durometer relative to proximally adjacent segments. Preferably, these segments have angled ends that allow each segment to be inserted and bonded into the segment prior to it. The outer jacket ultimately terminates at a distal of the microcatheter with the segment having the lowest durometer.

A microcatheter comprising:
- an elongated tube having a plurality of segments;
- each of said segments having a durometer that is lower than a proximally adjacent segment;
- a coil located beneath said elongated tube and having a pitch within a range of about 0.002 to 0.004 inches;
- and,
- an inner liner tube disposed beneath said coil.

A microcatheter sized for accessing a vasculature of a patient, comprising:
- a first tube segment having a first axis along its length and a first angled end having a first nonperpendicular angle relative to said first axis;
- and
- a second tube segment;
- wherein said angled end is disposed within said second tube segment, forming an elongated tube;
- said elongated tube having a passage open near a distal and proximal end of said elongated tube.
