Abstract
Methods for delivering a sheet-like implant to a target site including a means of deploying and orienting the sheet-like implant within the body.
Claims20
A method of delivering a sheet-like biologic implant through a cannula to a treatment site within a patient, the method comprising:
- inserting a distal end of the cannula through the patient's skin and proximate the treatment site such that a proximal end of the cannula is positioned exterior of the patient;
- inserting an elongated instrument having the sheet-like biologic implant secured to a distal end region thereof through the cannula with the sheet-like biologic implant in a folded configuration without a covering over the implant, where the sheet-like biologic implant has at least one suture attached thereto, the at least one suture extending proximally through the cannula and exterior of the patient, the elongated instrument has at least one opening in the distal end region, and the at least one suture extends through the at least one opening;
- transitioning the sheet-like biologic implant to a flattened configuration once the sheet-like biologic implant is positioned distal of the distal end of the cannula;
- and
- securing the sheet-like biologic implant to tissue at the treatment site in the flattened configuration using the at least one suture.

- inserting a distal end of the cannula through the patient's skin and proximate the treatment site such that a proximal end of the cannula is positioned exterior of the patient;
- inserting an implant delivery instrument having the sheet-like biologic implant secured between two spaced apart arms of the implant delivery instrument through the cannula with the sheet-like biologic implant in a folded configuration without a covering over the implant, where the sheet-like biologic implant has at least one suture attached thereto, the at least one suture extending proximally through the cannula and exterior of the patient, the implant delivery instrument has at least one opening in one of the arms, and the at least one suture extends through the at least one opening;
- thereafter, securing the sheet-like biologic implant in a flattened configuration over tissue at the treatment site using the at least one suture.
A method of delivering a sheet-like biologic implant through a cannula to a treatment site within a patient, the method comprising:
- inserting a distal end of the cannula through the patient's skin and proximate the treatment site such that a proximal end of the cannula is positioned exterior of the patient, the cannula including a seal therein;
- inserting an implant delivery instrument having the sheet-like biologic implant secured to a distal end region thereof through the seal of the cannula with the sheet-like biologic implant in a folded configuration without a covering over the implant, wherein the sheet-like biologic implant has at least one suture attached thereto, the at least one suture extending proximally through the cannula and exterior of the patient, the implant delivery instrument has at least one opening in the distal end region, and the at least one suture extends through the at least one opening;
- thereafter, unfolding the sheet-like biologic implant to a flattened configuration once the sheet-like biologic implant is positioned distal of the distal end of the cannula;
- and securing the sheet-like biologic implant to tissue at the treatment site in the flattened configuration using the at least one suture.
