Robotic sperm is here, and it’s not just for fertilization — it might help treat cancer, too

This is just too damned simple, you just repurpose this to tPA delivery. Do we have anybody in the stroke world with any brains and initiative at all? You just write a request for proposal and have researchers come back with cost estimates and solution ideas and  solve the damned problem of tPA bleeding.
The argument against tPA delivery here:

Against: And just what is the emperor of stroke wearing?

Everything in that article is solvable. But they would rather do the chicken little approach.

1. Correct diagnosis of bleed vs. clot.  See the Qualcomm Tricorder X Prize

2. Bleeding out even though the stroke was accurately categorized as a clot.

This is solvable by reducing the size of the bolus thru this robotic method or directed magnetic nanoparticles.
