I could see possible use in hemorrhages, rather than surgery. But since the Oynx glue seems to have not panned out I don't expect anyone will even attempt to see if it would work for strokes.

Wounds to crucial organs soon could be sealed in 60 seconds thanks to a new elastic and adhesive surgical glue.
Biomedical engineers from the U.S. and the University of Sydney have
developed a new glue that is ideal for sealing wounds in body tissues
that continually expand and relax, including lungs, hearts and arteries.
The glue—dubbed MeTro—can also work on internal wounds that are often
in hard-to-reach areas and usually require staples or sutures due to
surrounding body fluid hampering the effectiveness of other sealants.
“The beauty of the MeTro formulation is that, as soon as it comes in
contact with tissue surfaces, it solidifies into a gel-like phase
without running away,” lead author of the study, Assistant Professor
Nasim Annabi, Ph.D., from the Department of Chemical Engineering at
Northeastern University, said in a statement. “We then further stabilize
it by curing it on-site with a short light-mediated crosslinking
treatment.
“This allows the sealant to be very accurately placed and to tightly
bond and interlock with structures on the tissue surface,” she added.
The glue includes a built-in degrading enzyme that can be modified to
determine how long the sealant lasts in order to allow adequate time
for the wound to heal.
The researchers successfully tested the gel on sealed incisions in
the arteries and lungs of rodents and the lungs of pigs, without needing
sutures and staples.
“When you watch MeTro, you can see it act like a liquid, filling the
gaps and conforming to the shape of the wound,” University of Sydney's
Professor Anthony Weiss, Ph.D., said in a statement. “It responds well
biologically, and interfaces closely with human tissue to promote
healing.
“The gel is easily stored and can be squirted directly onto a wound
or cavity,” he added. “The potential applications are powerful - from
treating serious internal wounds at emergency sites such as following
car accidents and in war zones, as well as improving hospital
surgeries.”
Weiss said that the researchers will now move onto clinical testing for the new technology.
