Systems, tools, and methods for connecting to tissue
View Patent ↗Described are various embodiments of surgical procedure systems, devices, tools, and methods, useful for connecting tissue (e.g., soft tissue, organ tissue) to another tissue or to a surgical device such as an implant; specific methods can be useful for plastic surgery, treating pelvic conditions such as vaginal prolapse, incontinence, and other conditions caused by muscle and ligament weakness, and for general surgical procedures.
1. A soft tissue anchor comprising:
a lead end having an aperture and at least one lateral extension, the aperture configured to receive a needle tip of an insertion tool;
a follow end including a flexible segment, the flexible segment having at least one slot, the lead end configured to be inserted through the at least one slot; and
an elongate flexible tie including a first tie end and a second tie end defining a longitudinal axis, the first tie end connected to the lead end and the second tie end connected to the follow end,
wherein the aperture of the lead end includes a longitudinal axis that is disposed at an angle offset from the longitudinal axis of the tie.
2. The soft tissue anchor of claim 1 , wherein the tie has a tie length between the lead end and the follow end, the tie has a first tie cross-section at a location of first tie end connection to the lead end, and the lead end has a lead end cross-sectional profile that is larger than the first tie cross-section.
3. The soft tissue anchor of claim 2 , wherein the tie has a second tie cross-section at a location of second tie end connection to the follow end, and the follow end has a follow end cross-sectional profile that is larger than the second tie cross-section.
4. The soft tissue anchor of claim 1 , wherein the tie has a length in a range from 0.1 to 1 inch.
5. The soft tissue anchor of claim 1 , wherein the aperture has a diameter in a range from about 0.005 inch to about 0.05 inch.
6. The soft tissue anchor of claim 1 , wherein the anchor comprises flexible plastic and the anchor does not become permanently deformed when passed through soft tissue.
7. The soft tissue anchor of claim 1 , wherein the anchor is configured to be placed through a laparoscopic cannula to be located at a supportive tissue or a supported tissue.
8. The soft tissue anchor of claim 1 , wherein the at least one slot includes a first slot and a second slot, the second slot disposed apart from the first slot.
9. The soft tissue anchor of claim 1 , wherein the lead end comprises a tapered lengthwise profile, the lead end including a base, the at least one lateral extension including a first lateral extension and a second lateral extension, the first lateral extension extending laterally from the base in a first direction, the second lateral extension extending laterally from the base in a second direction opposite to the first direction.
10. The soft tissue anchor of claim 1 , wherein the follow end includes a handle, the flexible segment being disposed between the second tie end and the handle.
11. A method of connecting an implant to tissue or an organ, the method comprising:
providing the soft tissue anchor as recited at claim 1 ;
providing an implant;
engaging the implant with the soft tissue anchor; and
placing the soft tissue anchor at the tissue or organ to connect the implant to the tissue or organ.
12. The method of claim 11 , wherein the method is for treating a pelvic condition, and the pelvic condition is a condition of a male or female patient selected from the group consisting of: a condition of levator tissue, urinary incontinence, fecal incontinence; hernia, and a prolapse condition.
13. The method of claim 11 , wherein the method is a sacral colpopexy comprising laparoscopically placing the soft tissue anchor at a region of a sacral anatomy to hold the implant at the region of sacral anatomy, or laparoscopically placing the soft tissue anchor at vaginal tissue to hold the implant at the vaginal tissue.
14. The soft tissue anchor of claim 1 , wherein the aperture is disposed at an orthogonal angle with respect to the longitudinal axis of the tie.
15. A medical device comprising:
a soft tissue anchor including:
a lead end having an aperture and at least one lateral extension;
a follow end including a flexible segment, the flexible segment having at least one slot, the lead end configured to be inserted through the at least one slot; and
an elongate flexible tie including a first tie end and a second tie end defining a longitudinal axis, the first tie end connected to the lead end and the second tie end connected to the follow end,
wherein the aperture of the lead end includes a longitudinal axis that is disposed at an angle offset from the longitudinal axis of the tie; and
an insertion tool including a distal end, the distal end including a needle and a needle tip configured to engage the aperture to allow the insertion tool to push the lead end through tissue.
16. The medical device of claim 15 , wherein the needle is a curved needle having a radius of curvature in a range from about 0.1 to about 0.6 inch.
17. The medical device of claim 15 , wherein the needle, with the needle tip engaged with the aperture, is configured to be passed through a laparoscopic trocar.
18. The medical device of claim 15 , further comprising:
a pelvic implant.
19. The medical device of claim 15 , further comprising:
a pelvic Y-mesh implant configured to treat vaginal vault prolapse.
20. The medical device of claim 15 , wherein the aperture is disposed at an orthogonal angle with respect to the longitudinal axis of the tie.
