主权项 1. A nested cannula, comprising: two or more nested tubes, each tube having a distal end portion; and a composite tip shape extending distally from an end of the nested cannula, the composite tip shape includes the distal end portions of the two or more nested tubes such that when combined the distal end portions collectively contribute to the composite tip shape which improves one of distal advancement or proximal retraction during deployment; wherein the composite tip shape includes at least one additional portion (220) to form a continuous rounded end portion.
