Systems and methods relating to associating a medical implant with a delivery device
View Patent ↗The present invention provides devices and methods for associating an implantable sling with a delivery device for delivering the sling to an anatomical location in a patient.
1. A sling assembly comprising,
a sleeve having a first end and a second end,
a sling residing, at least partially, within the sleeve,
a dilator having a first end and a second end and attached to the first end of the sleeve,
an association loop extending into the second end of the dilator and located at a first end of the sling assembly and sized and shaped for associating the sling assembly with a shaft of a delivery device; and
a spring loaded mounting arrangement to enable the association loop to extend and retract axially relative to the dilator.
2. The assembly of claim 1 , wherein the association loop associates the sleeve with a delivery device.
3. The assembly of claim 1 , wherein the loop is formed from a single strand of material.
4. The assembly of claim 3 , wherein the strands of material is twisted.
5. The assembly of claim 1 , wherein the loop is formed from multiple strands of material.
6. The assembly of claim 5 , wherein the multiple strands are braided.
7. The assembly of claim 6 , wherein the multiple strands form a hollow tube.
8. The assembly of claim 1 , wherein the loop is coated with a shape retaining material.
9. The assembly of claim 1 , wherein the loop is formed from metal.
10. The assembly of claim 1 , wherein the loop is formed from polymer.
11. The assembly of claim 1 , wherein the loop has two ends embedded along the length of the dilator.
12. The assembly of claim 1 , comprising a fixed mounting arrangement between the dilator and the loop material within the dilator.
13. An implant delivery system comprising
a sleeve having a first end and a second end and a sling residing at least partially within the sleeve, a dilator having a first end and a second end and attached to the first end of the sleeve, and an association loop extending into the second end of the dilator and located at a first end of the sling assembly,
a spring loaded mounting arrangement to enable the loop to extend and retract axially relative to the dilator; and
a delivery device onto which the association loop may be hooked.
14. The delivery system of claim 13 , wherein the delivery device comprises a shaft having a proximal end and a distal end, and a slot located near the distal end of the shaft, the slot including a radial portion extending radially into the shaft to an inner terminal end, and an axial portion extending axially along the shaft from the inner terminal end of the radial portion.
15. The delivery system of claim 14 , wherein the association loop hooks onto the slot by sliding radially along the radial portion and distally along the axial portion.
16. A sling assembly delivery kit comprising:
a sling assembly having,
a sleeve having a first end and a second end,
a sling residing, at least partially, within the sleeve,
a dilator having a first end and a second end attached to the first end of the sleeve,
an association loop extending into the second end of the dilator and located at a first end of the sling assembly;
a spring loaded mounting arrangement to enable the association loop to extend and retract axially relative to the dilator; and
a first delivery device onto which the first association loop may be hooked.
17. The kit of claim 16 comprising,
second association loop located at a second end of the sling assembly, sized and shaped to be hooked onto the first device.
18. The kit of claim 16 comprising,
a second association loop located at a second end of the sling assembly and
a second delivery device onto which the second association loop may be hooked.
