Claims11
A method for separating a tissue section from a body comprising:
- placing a tissue separation device adjacent to a target tissue section;
- moving an open outer end of the tissue separation device from a first position, along a radially-expanding and then radially-contracting path thereby, and to a second position, thereby creating a separated tissue section having a radially-expanding and then radially-contracting profile created by the path of the open outer end of the device.
A method for removing a tissue section from a body comprising:
- percutaneously placing a tissue separation device adjacent to a target tissue section using a hollow introducer tube;
- moving an open outer end of the tissue separation device from a first position within the introducer tube, along a radially-expanding and then radially-contracting path, and to a second position, thereby creating a separated tissue section having a radially-expanding and then radially-contracting profile created by the path of the open outer end of the device
- removing the separated tissue section, housed within the tissue separation device, from the body.
