Skin penetration apparatus including multiple needle configuration
First Claim
1. An assembly of needles for penetrating the skin of a subject, comprising:
- a plurality of elongated needles, each having a base portion and a tip, each of the needles being disposed in contiguous substantially parallel array in at least one tier with all of the tips thereof substantially aligned along a common axis at a first angle of skewed, non-perpendicular relationship to axes of elongation of the needles; and
a base disposed about the base portion of the needles for rigidly constraining the plurality of needles within the assembly to a boundary limit along the elongated lengths of the needles remote from the tips thereof that is aligned along a common axis at a second angle of skewed, non-perpendicular relationship to the axes of elongation of the needles.

Abstract
An array of elongated needles for penetrating skin is assembled in single or multiple tiers with the tips or points thereof substantially aligned along an axis or plane that is skewed in non-perpendicular orientation relative to the axes of elongation of the needles. The needles are rigidly confined in the assembly within a common base portion that extends to a boundary limit remote from the tips which is oriented along an axis or plane that is skewed in non-perpendicular orientation relative to axes of elongation of the needles. The axis or plane of the needle tips may be substantially parallel or non-parallel to the axis or plane of the boundary limit to promote selected resilient flexure characteristics of the needles in the portions thereof between the boundary limit of the base and the needle tips.
