Key result
Increased needle insertion speed into the heart reduces the force required to initiate cutting and tissue displacement, suggesting automated insertion could improve performance.
Why the study?
Does increased needle insertion velocity reduce tissue motion and cutting force in cardiac tissue?
Population

Automated high-velocity insertion may reduce cardiac tissue trauma in procedures; hypothesis-generating in animals, human validation needed.
Does increased needle insertion velocity reduce tissue motion and cutting force in cardiac tissue?
Automated, high-velocity needle insertion may improve performance in minimally invasive procedures by reducing tissue deformation and cutting force.
Heverly et al. (2006) studied Needle based intervention procedures. Increased needle velocity vs. Lower needle velocity was evaluated on Force required to initiate cutting and tissue displacement. Increased needle insertion speed into the heart reduces the force required to initiate cutting and tissue displacement, suggesting automated insertion could improve performance.
