Abstract
Systems, devices, and methods for deploying a graft to a treatment site of a patient. Exemplary systems include a device body and an insertion mechanism. The device body can have a handle and a trigger. The insertion mechanism can be in operative association with the device body, and can have an outer sheath, a support shaft disposed at least partially within the outer sheath, an expansion mechanism coupled with the support shaft, and a graft in contact with the expansion mechanism.

A suture loading block device for loading a graft with a suture, comprising:
- a top body having a first contoured surface;
- a bottom body coupled with the top body, the bottom body having a second contoured surface that is complementary to the first contoured surface of the top body;
- and
- a locking mechanism configured to lock the top body and the bottom body together when the loading block is in a closed configuration,
- wherein the first contoured surface and the second contoured surface define a graft space that is configured to receive the graft therein when the loading block device is in the closed configuration,
- wherein the first contoured surface comprises a plurality of first ridge troughs,
- wherein the second contoured surface comprises a plurality of second ridge troughs, and
- wherein the plurality of first ridge troughs and the plurality of second ridge troughs provide a passageway that is configured to receive a needle loaded with the suture therethrough when the loading block device is in the closed configuration.
A method of loading a graft with a suture, the method comprising:
- placing the graft on a bottom body of a suture loading block device;
- closing a top body of the suture loading block device onto the bottom body, so that the suture loading block device is in a closed configuration and the graft is disposed in a graft space defined by the bottom body and the top body;
- and
- passing a needle loaded with the graft through a passageway defined by the top body and the bottom body, so that the suture is loaded on the graft,
- wherein the top body has a first contoured surface, the bottom body has a second contoured surface that is complementary to the first contoured surface of the top body, and wherein the first contoured surface and the second contoured surface define the graft space that is configured to receive the graft therein when the suture loading block device is in the closed configuration, and
- wherein the first contoured surface comprises a plurality of first ridge troughs, the second contoured surface comprises a plurality of second ridge troughs, and wherein the plurality of first ridge troughs and the plurality of second ridge troughs provide the passageway.
