## Description

The purpose of Amendment 1 to DARPA-PS-25-34, the Medics Autonomously Stopping Hemorrhage (MASH) Program Solicitation (PS), is to clarify that proposal abstract submissions must include Attachments A-C. Details are provided in Attachment A, to mirror guidance provided in Section 4.1 of DARPA-PS-25-34.

The Defense Advanced Research Projects Agency (DARPA) is soliciting proposals to develop demonstrator autonomous systems to stabilize torso hemorrhage without need of a surgeon in forward medical sites, providing 48+ hours to reach definitive care. The Medics Autonomously Stopping Hemorrhage (MASH) program is seeking approaches that merge multi-modal automated bleed detection and localization with automated, minimally invasive robotic end effectors and sensors.

MASH’s vision is to push the standard of pre-hospital hemorrhage control to 48 hours; stop lethal forms of torso hemorrhage without a surgeon; and provide minimally invasive surgery (MIS) a path to enter the trauma market and utilize full autonomy.
