  • Patent number: 10383595
    Abstract: Disclosed is a system and method for the placement of elongate medical members within a patient's body using coaptive ultrasound that combines magnetic guidance with ultrasound visualization of the medical member in the patient's body. A coaptive ultrasound probe adaptor magnetically attracts an elongate medical member within the patient with sufficient force so as to allow the operator to manually guide the member to its intended location. The adaptor mates with an ultrasound probe to provide the medical operator ultrasound feedback of the position of the member, thus allowing internal placement without the need for more specialized medical equipment.
