Methods and apparatus for treating ventral wall hernia
View Patent ↗This invention relates to a surgical implant system for repairing abdominal hernias and is particularly useful for repairing ventral hernias. In particular, the present invention relates to an implant, a delivery device and a method for implanting the implant. The implant is implanted in a substantially slackened condition relative to the ventral wall.
1. A device for securing an engagement member extending from an implant to a ventral wall comprising:
a passer configured to penetrate at least a portion of the ventral wall in a generally circular path when advanced, said passer having a connector adapted to couple to the engagement member after penetrating the wall, and said passer adapted to pull the engagement member through the path when retracted, a finger ring being located on a distal end segment of the device and configured to at least partially surround a finger of an operator such that tactile feel of the operator can guide the device to an anatomical position.
2. The device of claim 1 , wherein the path encircles a tendon, bone, ligament, fascial tissue or muscle portion.
3. The device of claim 1 , wherein the passer is made from a super elastic alloy having a pre-set radius, the passer confined by an outer tube and configured such that as the passer is advanced from the tube, the distal end penetrates tissue in a generally circular path.
4. The device of claim 3 , wherein the path encircles a tendon, bone, ligament, fascial tissue or muscle portion.
5. The device of claim 1 further comprising a light source attached to the device and configured such that the light penetrates the ventral wall to aid positioning of the device to an anatomical position.
6. A kit for the repair of a ventral wall hernia comprising:
an implant member and at least a first engagement member defining a first end distanced from the implant member, a second engagement member also extending from the implant and defining a second end distanced from the implant member; and
a template configured to aid a person in marking an intended position of the engagement members of the implant, the template being positionable on the abdomen of a patient over an actual or intended incision, an outline being on the template and corresponding to the implant, respective locations of the engagement members being indicated on the template, whereby a person can place the template on the patient and mark the respective locations of the engagement members on the skin of the patient such that after the template is removed from the patient, the marks guide placement of the engagement members through the ventral wall of the patient.
7. The kit of claim 6 , wherein said kit is adapted to secure the implant to the ventral wall such that when implanted the implant is in a substantially slackened condition relative to the ventral wall.
8. The kit of claim 6 , further comprising a retention tube, said tube adapted for placement into the incision after removal of a funnel member and configured to receive leaders connected to an end of the engagement members so that the leaders may be pulled to adjust tension.
