Abstract

In one embodiment, the handheld injection device includes a first housing having a first axis and a second housing having a second axis. In one embodiment, the second housing is configured to support a needle. In one embodiment, the first axis and a second axis form an adjustable angle between about 180 degrees and about 90 degrees.

Claims

1. A handheld injection device comprising:

a housing having a first axis;

a first cartridge configured to contain a first injectable fluid;

a second cartridge configured to contain a second injectable fluid;

the first and second cartridges being contained in a distal region of the housing and disposed in a side-by-side relationship with respect to each other;

an adjustable tip portion coupled to the housing and configured to support a needle having a second axis, the adjustable tip portion configured to rotate between a plurality of predetermined positions defined by an angle between the first axis and the second axis, the adjustable tip portion including a plurality of depressions and ball bearings configured to engage the projections to fix the tip portion in place at a selected one of the plurality of predetermined positions; and

an injection drive mechanism configured to cause extrusion of a mixture of the first and second injectable fluids at a desired ratio from the needle.

2. The device of claim 1 wherein the adjustable tip portion further includes first and second projections configured to stop the adjustable tip portion from being rotated past a fixed position.

3. The device of claim 1 wherein the injection drive mechanism comprises a processor and a memory device storing instructions executable by the processor.
