Patent ID: 8333721

Claim:
An ultrasound medical treatment system comprising an end effector insertable into a patient, wherein the end effector includes a tissue-retaining device, wherein the tissue-retaining device includes a first tissue-retaining member having an ultrasound imaging and medical-treatment transducer and includes a second tissue-retaining member, and wherein the first and second tissue-retaining members are operatively connected together to retain patient tissue between the first and second tissue retaining members and to release patient tissue so retained, wherein the first tissue-retaining member is a distal end portion of a first tube, wherein a second tube is oriented substantially parallel to the first tube, wherein a first and second link members pivotally attached to the first tissue-retaining member and to the second tube at pivot points creating a hinged parallelogram defined by a proximal portion of the first tissue-retaining member, a distal portion of the second tube, and the first and second link members, and a cable operatively connected to the hinged parallelogram to move the second tissue-retaining member toward and away from the first tissue-retaining member.
