System For Positioning Support Mesh in a Patient
A surgical system for positioning organs in a patient. The surgical system includes a mesh retrieval device and a mesh support structure. The mesh support structure is suitable for implanting in the patient to position the organ at a desired location in the patient. The mesh retrieval device is engageable with the mesh support structure. The system includes specialized needles and cannulas for delivery of the mesh retrieval device to the mesh support structure and the subsequent positioning of the mesh support structure, which results in the positioning of the organ. Methods of positioning organs in a patient using such devices are also disclosed.
1 . A surgical system for positioning organs in a patient, the surgical system comprising:
a mesh retrieval device comprising a base and at least one hook extending therefrom; and
a mesh support structure adapted to be implanted in the patient to position the organ at a desired location in the patient, wherein
the mesh retrieval device is adapted to engage the mesh support structure.
2 . The surgical system of claim 1 , wherein the mesh retrieval device is fabricated from a hook portion of a hook and loop fastener or from a ballized fastening device.
3 . The surgical system of claim 1 , wherein the mesh retrieval device is oriented in a substantially cylindrical configuration.
4 . The surgical system of claim 3 , wherein the hooks extend towards an interior of the mesh retrieval device.
5 . The surgical system of claim 1 , wherein the mesh retrieval device has a tear strip or perforation that facilitates forming a slit in the base.
6 . The surgical system of claim 1 , and further comprising a cannula through which the mesh retrieval device may be inserted.
7 . The surgical system of claim 6 , wherein the base has a substantially flat configuration when the mesh retrieval device is inserted through the cannula.
8 . The surgical system of claim 6 , wherein the cannula comprises
a first portion substantially rigid, and
a second portion having a tapered edge, said portion being distal to the first portion and less rigid than said first portion.
9 . A surgical system for positioning a mesh support structure in a patient, the surgical system comprising:
a needle including a handle extending therefrom, wherein the handle facilitates insertion of the needle into the patient; and
a cannula including an opening formed therein that is adapted to receive at least a portion of the needle.
10 . The surgical system of claim 9 , wherein the needle has a flange extending from an outer surface thereof.
11 . The surgical system of claim 10 , wherein the flange is positioned proximate to a proximal end of the cannula.
12 . The surgical system of claim 9 , further comprising:
a leader for engagement of said mesh support structure to facilitate placement through said cannula.
13 . A surgical system for a positioning support structure in a patient, the surgical system comprising:
a mesh retrieval device including a base from which at least one hook extends;
a sheath that substantially encompasses the mesh retrieval device; and
a needle that is adapted to engage at least one of the mesh retrieval device and the sheath for positioning the mesh retrieval device in the patient.
14 . The surgical system of claim 13 , wherein the mesh retrieval device is fabricated from a hook portion of a hook and loop fastener or from a ballized fastening device.
15 . The surgical system of claim 13 , wherein the mesh retrieval device is oriented in a substantially cylindrical configuration.
16 . The surgical system of claim 13 , wherein said at least one hook extends toward an interior of the mesh retrieval device.
