Abstract
A surgical assembly for marking a tumor includes a surgical instrument and an elongated tissue marker. The surgical instrument includes an ultrasonic probe and a needle configured to move in a distal direction through a channel of the ultrasonic probe from a retracted position to a deployed position. The tissue marker is disposed within the needle and deployable therefrom. The tissue marker includes a distal portion and a plurality of fixation elements coupled to the distal portion. Upon deployment of the tissue marker from the needle, the plurality of fixations elements are configured to move from a collapsed configuration to an expanded configuration to anchor in a tumor.
Claims28
A surgical assembly for marking a tumor, comprising:
- a surgical instrument including:
- an ultrasonic probe having a channel defined therein;
- and
- a needle configured to move in a distal direction through the channel of the ultrasonic probe from a retracted position to a deployed position;
- and
- an elongated tissue marker disposed within the needle and deployable therefrom, the tissue marker including a distal portion and a plurality of fixation elements coupled to the distal portion, wherein upon deployment of the tissue marker from the needle, the plurality of fixations elements are configured to move from a collapsed configuration to an expanded configuration to anchor in a tumor.
A surgical assembly for marking a tumor, comprising:
- a surgical instrument including an ultrasonic probe;
- and
- an elongated tissue marker configured to be operably coupled to the surgical instrument and deployable therefrom, the tissue marker including:
- a plurality of fixation elements coupled to a distal portion of the tissue marker;
- and
- an actuator coupled to the plurality of fixation elements such that actuation of the actuator results in movement of the plurality of fixation elements from a collapsed configuration toward an expanded configuration to anchor in a tumor.
A tissue marker, comprising:
- a distal portion;
- and
- a plurality of fixation elements coupled to the distal portion, wherein upon deployment of the tissue marker, the plurality of fixations elements are configured to move from a collapsed configuration to an expanded configuration to anchor in a tumor.
