In one embodiment, therefore, an ultrasound probe is disclosed, comprising a body, a lens included on head portion of the body, a stabilizing portion extending from the body and configured to stabilize the body on a skin surface of a patient without user assistance, and a finger grip portion configured to enable a user of the probe to grasp and maneuver the probe during use thereof with no more than two fingers on a single hand of the user.

Abstract: Disclosed herein is a catheter placement system with a stiffening system and associated methods thereof. The catheter placement system can include a needle, catheter (e.g. rapid insertion central catheter), one or more guidewires, and a stiffening system, configured to place the catheter while containing portions of the catheter placement system that contact the patient within a sterile environment. Advantageously, the catheter placement system can provide all tools necessary for accessing a vasculature, dilating the insertion site and placing the catheter within a single device, mitigating repeated insertion of multiple tools and reducing the risk of introducing pathogens or the like. Further, the overall time required to place the catheter is reduced, reducing patient down time and improving patient outcomes.
