Estimating the term…
A tissue traction system allowing dynamic application of traction and/or repositionable “pulley” points for application of traction to tissue at a treatment site. The traction may be applied by an elongate element extending from a tissue-lifting tissue-engagement element engaged with tissue at the treatment site, to a traction-adjusting tissue-engagement element engaged with tissue at a force vector-changing location spaced apart from the target tissue, and out of the patient for application of force to the elongate element from outside the patient. The position of the traction-adjusting tissue-engagement element may be adjusted within the patient's body to adjust the traction force vector applied along the elongate element to the tissue-lifting tissue-engagement element.
A tissue traction system for transluminal delivery into a patient's body to apply traction to tissue at a treatment site within the patient's body, said tissue traction system comprising:
A tissue traction system for transluminal delivery into a patient's body to apply traction to tissue at a treatment site within the patient's body, said tissue traction system comprising:
a tissue-lifting tissue-engagement element;
a traction-adjusting tissue-engagement element;
an elongate element having a first end coupled to said tissue-lifting tissue-engagement element, and extending from said tissue-lifting tissue-engagement element to be operably associated with said traction-adjusting tissue-engagement element;
an elongate member operably coupled with said traction-adjusting tissue-engagement element to move said traction-adjusting tissue-engagement element to be engaged with tissue at a first location, to move said traction-adjusting tissue-engagement element from the first location to a second location, and to move said traction-adjusting tissue-engagement element to be engaged with tissue at the second location to adjust the traction force vector applied by said elongate element to the tissue at the treatment site via said tissue-lifting tissue-engagement element.
said tissue-lifting tissue-engagement element is helical and said jaws of said traction-adjusting tissue-engagement element are engageable with said tissue-lifting tissue-engagement element to rotationally engage said tissue-lifting tissue-engagement element with tissue to engage tissue;
said tissue-lifting tissue-engagement element includes an extension graspable by said jaws of said traction-adjusting tissue-engagement element to rotationally advance the tissue-lifting tissue-engagement element into tissue.
A method of applying traction to tissue within a patient, said method comprising:
transluminally advancing a tissue-lifting tissue-engagement element and a traction-adjusting tissue-engagement element with an elongate element extending therebetween to a treatment site within a patient;
engaging the tissue-lifting tissue-engagement element with tissue at the treatment site;
engaging the traction-adjusting tissue-engagement element with tissue at a first location spaced apart from the treatment site;
extending the elongate element from the tissue-lifting tissue-engagement element to the traction-adjusting tissue-engagement element and proximally to outside the patient;
proximally pulling on the elongate element from outside the patient to apply traction to tissue at the treatment site via the elongate element and the tissue-lifting tissue-engagement element.
