Estimating the term…
A tissue separator having a tissue-separating end effector with a blunt dissector, such as an expandable member configured to separate tissue, and a fixation member. The fixation member inhibits and preferably prevents rebound of the expandable member as the expandable member expands against tissue to separate the tissue. The expandable member may be an inflatable balloon or tunnelling balloon. The fixation member may be an expandable member. The fixation member may be fixed in close proximity to the proximal end of the expandable member, or may be movable with respect to the expandable member.
A tissue separator capable of being navigated transluminally to a treatment site within a patient and insertable through an incision formed in tissue at the treatment site to create a third space within the tissue, said tissue separator comprising:
A system for separating tissue within a patient to create a third space within the tissue, said system comprising:
a cutting device capable of being navigated transluminally within a patient's body to form an incision in the tissue;
a tissue separator capable of being navigated transluminally to the treatment site and insertable through an incision formed by said cutting device and into the tissue, said tissue separator comprising:
a flexible elongate member configured to be navigated within curved or tortuous body passages to the treatment site and having a distal end;
an end effector positioned along the distal end of said flexible elongate member and configured to be inserted through the incision formed by said cutting device, said end effector comprising an expandable member at the distal end of said flexible elongate member, and a fixation member proximal to said expandable member.
A method of creating third space within tissue within a patient's body, said method comprising:
inserting a distal end of an end effector of a tissue separator through an incision in tissue within a patient's body and into the tissue;
expanding an expandable member on the distal end of the end effector within the tissue to separate the tissue and to create an initial third space within the tissue;
collapsing the expandable member;
expanding a fixation member of the end effector within the initial space within the tissue to anchor the end effector with respect to the tissue;
expanding the expandable member to further separate tissue to expand the size of the initial third space within the tissue.
