Abstract

Claims (70)

1 . A tissue anchoring device, comprising:

an elongate member; and

a plurality of side members, each of which has a first end and a second end;

each of the plurality of side members being coupled to, or integral with, the elongate member at the first end; and

each of the plurality of side members 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 members moves closer to the elongate member, permitting passage of the device through the tissue in the second direction.

2 . A tissue anchoring system comprising:

the device of claim 1 ; and

an elongate member having a lumen passing therethrough, the elongate member configured to hold the device when the device is in the collapsed state, for delivery of the device into the tissue.

3 . 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 a tissue, the support member comprising a first portion and a second portion; and

first and second suspension members, the first suspension member coupled to, and movable with respect to, the first portion of the support member, the second suspension member coupled to, and movable with respect to, the second portion 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 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.

4 . The device of claim 3 , wherein the first suspension member is slidable with respect to the first portion of the support member, and the second suspension member is slidable with respect to the second portion of the support member.

5 . The device of claim 3 , further comprising an anchor member coupled to, or integral with, at least one of the first and second suspension members.

6 . The device of claim 5 , wherein the anchor member comprises:

an elongate member; and

a plurality of side members, each of which has a first end and a second end;

each of the plurality of side members being coupled to, or integral with, the elongate member at the first end; and

each of the plurality of side members subtending an acute angle with respect to the elongate member when the anchor member is in an expanded state;

wherein advancement of the anchor member in a first direction results in a securing of the anchor member in a tissue;

wherein, after the securing, advancement of the anchor member in a second direction, opposite the first direction, through the tissue results in the anchor member changing from the expanded state to a collapsed state as the second end of each of the plurality of side members moves closer to the elongate member, permitting passage of the anchor member through the tissue in the second direction.

7 . The device of claim 5 , wherein the anchor member comprises at least one of a hook, a dart, a barb, and a clasp.

8 . A minimally invasive method, for elevating soft tissue in a body, comprising:

providing a supporting device, comprising a first portion, a second portion, and a support member positioned between the first portion and second portion;

advancing the first portion of the supporting device into the body, through a single incision, to a first location in the body;

advancing the second portion of the supporting device into the body, through the incision, 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.

9 . The method of claim 8 , wherein the shifting comprises elevating the soft tissue superiorly.

10 . The method of claim 8 , wherein both of the first and second locations are located superior to the incision.

11 . The method of claim 8 , wherein at least one of the first and second locations is located superior to the incision.

12 . The method of claim 8 , further comprising drawing the soft tissue toward at least one of the first and second locations.

13 . The method of claim 8 , wherein the soft tissue comprises breast tissue.

14 . The method of claim 8 , wherein the first and second locations are substantially the same location.

15 . The method of claim 8 , wherein at least one of the first and second locations is at a fascia.

16 . The method of claim 8 , wherein at least one of the first and second locations is at a muscle.

17 . The method of claim 8 , wherein at least one of the first and second locations is at a clavicle.

18 . The method of claim 8 , wherein at least one of the first and second locations is at a rib.

19 . The method of claim 8 , wherein the securing comprises suturing the first portion.

20 . The method of claim 8 , wherein the securing comprises positioning an anchoring member at the first location.

21 . The method of claim 20 , wherein the anchoring member comprises at least one of a hook, a dart, a barb, and a clasp.

22 . The method of claim 8 , further comprising securing the second portion of the supporting device at the second location.

23 . The method of claim 22 , wherein the incision is made during a first time period, and the first and second portions are secured during a second time period, and no additional incision is made in the body between the first and second time periods, and no additional incision is made in the body during the second time period.

24 . The method of claim 22 , wherein a distance between the first and second locations is greater than a longest dimension of the support member.

25 . The method of claim 8 , wherein the first and second portions comprise suspension elements.

26 . The method of claim 8 , wherein the incision is no greater than about 1.0 centimeter in length.

27 . The method of claim 8 , wherein the incision is no greater than about 0.5 centimeters in length.

28 . The method of claim 8 , wherein the incision is substantially parasagittal in orientation.

29 . The method of claim 8 , wherein the incision is transverse to a long axis of the body.

30 . A method, of dissecting breast tissue, comprising:

inserting a distal end of an elongate member into one of a medial and a lateral aspect of a breast;

after the inserting, advancing the distal end inferiorly within the breast; and

after the advancing the distal end inferiorly, advancing the distal end superiorly within the breast to the other of the medial and lateral aspect, and then out of the breast, such that the distal end and a proximal end of the elongate member are outside the breast and a central portion of the elongate member, between the distal end and the proximal end, is within the breast.

31 . The method of claim 30 , wherein the advancing the distal end inferiorly comprises advancing the distal end to a point inferior to the areola of the breast.

32 . The method of claim 30 , wherein the advancing the distal end inferiorly comprises dissecting breast tissue.

33 . The method of claim 30 , wherein the elongate member comprises a needle.

34 . The method of claim 30 , wherein the elongate member is arcuate.

35 . The method of claim 30 , wherein the elongate member comprises a sheath.

36 . The method of claim 30 , wherein the distal end is sharp.

37 . The method of claim 30 , further comprising advancing a support member along the elongate member.

38 . The method of claim 37 , further comprising shifting breast tissue with the support member.

39 . The method of claim 30 , further comprising:

creating a channel in the breast tissue that extends from a point at which the elongate member is inserted into the breast; and

expanding a cross-sectional dimension of the channel.

40 . The method of claim 39 , wherein the expanding the cross-sectional dimension of the channel comprises expanding an expandable member within the channel.

41 . The method of claim 40 , wherein the expandable member comprises distal end having a polygonal structure.

42 . The method of claim 41 , wherein the polygonal structure comprises a quadrilateral shape.
