MINIMALLY INVASIVE TISSUE SUPPORT
Described are methods and apparatus for use in supporting tissue in a patient's body. In some embodiments, the patient's breast is supported. In some embodiments, the methods provide ways of supporting and adjusting tissue, and the apparatus includes components and embodiments for supporting and adjusting the tissue. Some embodiments include a supporting device, having a first portion, a second portion, and a support member positioned between the first portion and second portion. Some embodiments include advancing the first portion of the supporting device into the body to a first location in the body; advancing the second portion of the supporting device into the body to a second location in the body; securing the first portion of the supporting device at the first location; and shifting soft tissue in the body with the support member.

21 . A tissue anchoring device, comprising:
a flexible elongate member comprising a longitudinal axis; and
one or more anchoring members inserted into a center of the elongate member generally along the longitudinal axis of the flexible elongate member,
wherein the one or more anchoring members comprise an outer diameter less than the inner diameter of the flexible elongate member,
wherein the one or more anchoring members comprise a portion that extends radially outwardly from the flexible elongate member to anchor within tissue,
wherein the anchoring member comprises a material different from that of the elongate member.
22 . The device of claim 21 , wherein the one or more anchoring members are at least partially surrounded by a flexible elongate member at a first end.
23 . The device of claim 21 , wherein the elongate member comprises a flexible suture.
24 . The device of claim 21 , wherein the elongate member comprises a braided suture.
25 . The tissue anchoring device of claim 21 , wherein the device in the collapsed state may pass through the tissue in a first direction, and wherein tensioning the device in a second direction results in the device changing from a collapsed state to an expanded state.
26 . The device of claim 21 , wherein the one or more anchoring members in a collapsed state may pass through the tissue in a first direction, and wherein tensioning the device in a second direction results in the one or more anchoring members changing from a collapsed state to an expanded state.
27 . The device of claim 26 , wherein after tensioning in a second direction the one or more anchoring members may return to the collapsed state and pass through the tissue in a first direction when tensioned in a first direction.
28 . A tissue anchoring device, comprising:
a flexible elongate member; and a branched member comprising an elongate main branch and a plurality of side branches, each of which has a first end and a second end; the branched member configured to be inserted into the center of the elongate member such that when inserted into the center of the elongate member and pulled in appropriate direction the plurality of side branches will spread outwardly from the main branch and pierce the elongate member, each of the plurality of side branches subtending an acute angle with respect to the elongate member when the device is in an expanded state; wherein advancement of the device in a first direction results in a securing of the device in a tissue; wherein, after the securing, advancement of the device in a second direction, opposite the first direction, through the tissue results in the device changing from the expanded state to a collapsed state as the second end of each of the plurality of side branches moves closer to the elongate member, permitting passage of the device through the tissue in the second direction; wherein applying tension to the elongate member in the expanded state causes the second end of each of the plurality of side branches to rotate with respect to and move closer to the elongate member.
29 . The tissue anchoring device of claim 28 , wherein the elongate member comprises a flexible suture.
30 . The tissue anchoring device of claim 28 , wherein the elongate member comprises a braided suture.
31 . The tissue anchoring device of claim 28 , wherein the elongate member comprises a monofilament.
32 . The tissue anchoring device of claim 28 , wherein each of the plurality of side members completely surround a core of the elongate member.
