Minimally invasive tissue support
Embodiments of apparatus and methods for tissue lifting, or for correcting a ptosis condition caused by tissue stretching, are described. In some embodiments a tissue is supported by a support member. In some embodiments, tension is applied to a support member through at least one suspension member. The described embodiments provide examples of methods and apparatus effective for use in lifting or otherwise applying tension to various tissues, including tissues of the breast, buttock, thigh, arm, abdomen, neck and face.
1. A system for use in supporting a tissue in a patient's body, comprising:
a device, the device comprising:
a support member, adapted to engage at least a portion of the tissue, the support member comprising a first end and a second end, the support member further comprising a plurality of support elements; and
first and second suspension members, the first suspension member being coupled to the first end of the support member, the second suspension member being coupled to the second end of the support member;
wherein at least one of the first and second suspension members is configured to be secured to a location in the patient's body;
wherein the plurality of support elements is configured to distribute a load, from the tissue engaged by the support member, imposed on the support member; and
wherein at least one of the first and second suspension members is configured to transmit a force through the support member, the force effective to move the engaged portion of the tissue from a first position to a second position; and
a delivery system for delivering the device, wherein:
the delivery system comprises a first needle and a second needle, the first needle being configured to be coupled to the device and the second needle having a tubular body for slidably receiving the first needle;
the first needle has a first radius of curvature and the second needle has a second radius of curvature, the first radius of curvature being different from the second radius of curvature; and
the second needle is configured to adopt a new radius of curvature, wherein the new radius of curvature depends on how much of the first needle is held within the second needle.
2. The system of claim 1 , wherein the first suspension member is coupled to each support element at a first end of each support element, and the second suspension member is coupled to each support element at a second end of each support element.
3. The system of claim 1 , wherein the second position is superior to the first position.
4. The system of claim 1 , wherein the second position is at least one of posterior, medial, and lateral, relative to the first position.
5. The system of claim 1 , wherein the second position is posterior to the first position.
6. The system of claim 1 , wherein each of the plurality of support elements is elongate and has a length extending along an arc, or line, that extends between the first end of the support member and the second end of the support member;
wherein a first of the plurality of support elements is spaced apart from a second of the plurality of support elements along at least about 10% of a length of the first of the plurality of support elements; and
wherein the length of the plurality of support elements extends from the first end of the support member to the second end of the support member.
7. The system of claim 1 , wherein a first of the plurality of support elements is spaced apart from a second of the plurality of support elements along at least about 30% of a length of the first of the plurality of support elements; and
wherein the length of the plurality of support elements extends from the first end of the support member to the second end of the support member.
8. The system of claim 1 , wherein at least one of the support elements is fusiform shaped.
9. The system of claim 1 , wherein at least one suspension member is configured to be secured to at least one of muscle, fascia, bone, ligament, tendon, and skin.
10. The system of claim 1 , wherein the portion of the tissue being engaged comprises at least one of breast tissue, buttock tissue, facial tissue, arm tissue, abdominal tissue, and leg tissue.
11. The system of claim 1 , wherein each support element comprises at least one of an elongate member and a mesh.
12. The system of claim 1 , wherein each of the plurality of support elements is coupled to a separator, effective to maintain spacing between adjacent support elements.
13. The system of claim 1 , wherein the support member comprise an engagement member, effective to limit movement of the support member relative to the engaged portion of the tissue.
14. The system of claim 13 , wherein the engagement member comprises at least one of a barb, a hook, and a suture.
15. The system of claim 1 , wherein at least a portion of the device comprises a biodegradable material.
16. The system of claim 1 , further comprising a coating effective to enhance at least one of biocompatibility and healing.
17. The system of claim 1 , wherein the support member is made from a different material than the first and second suspension members.
18. The system of claim 1 , wherein the support member comprises color coding to indicate regions of the support member that include support elements.
19. A device, for use in supporting a tissue in a patient's body, comprising:
a support member, adapted to engage at least a portion of the tissue, the support member comprising a first end and a second end, the support member further comprising a plurality of support elements;
first and second suspension members, the first suspension member being coupled to the first end of the support member, the second suspension member being coupled to the second end of the support member;
wherein at least one of the first and second suspension members is configured to be secured to a location in the patient's body;
wherein the plurality of support elements is configured to distribute a load, from the tissue engaged by the support member, imposed on the support member; and
wherein at least one of the first and second suspension members is configured to transmit a force through the support member, the force effective to move the engaged portion of the tissue from a first position to a second position; and
a linking device coupled to the first end of the support member, wherein the linking device comprises a tubular body configured to receive a received end, the received end being the second end of the same support member or an end of a different support member, to link the received end to the first end of the support member, and wherein the linking device further comprises a skived area near the first end of the tubular body.
