Abstract
A system may include a delivery device configured to deploy a perianal fistula closure device and the perianal fistula closure device configured to close a perianal fistula. The delivery device may include a helical catheter. The perianal fistula closure device may include a cap, a suture comprising a plurality of uni-directional barbs, and an anchor connected to an end of the suture comprising a plurality of uni-directional quills.
Claims21
A system, comprising:
- a delivery device configured to deploy a perianal fistula closure device, comprising:
- a helical catheter;
- and
- the perianal fistula closure device configured to close a perianal fistula, comprising:
- a cap,
- a suture comprising a plurality of uni-directional barbs that are configured in a first direction and configured to resist movement in a direction of insertion of the perianal fistula closure device, and
- an anchor connected to an end of the suture comprising a plurality of uni-directional quills that are configured in a second direction opposite to the first direction, and configured to resist movement in a direction that is opposite to the direction of insertion of the perianal fistula closure device.
A perianal fistula closure device configured to close a perianal fistula, comprising:
- a cap;
- a suture comprising a plurality of uni-directional barbs that are configured in a first direction and configured to resist movement in a direction of insertion of the perianal fistula closure device;
- and
- an anchor connected to an end of the suture comprising a plurality of uni-directional quills that are configured in a second direction opposite to the first direction, and configured to resist movement in a direction that is opposite to the direction of insertion of the perianal fistula closure device.
A device, comprising:
- a perianal fistula closure device comprising:
- a cap;
- a suture comprising a plurality of uni-directional barbs that are configured in a first direction and configured to resist movement in a direction of insertion of the perianal fistula closure device;
- and
- an anchor connected to an end of the suture comprising a plurality of uni-directional quills that are configured in a second direction opposite to the first direction, and configured to resist movement in a direction that is opposite to the direction of insertion of the perianal fistula closure device;
- and
- a delivery device comprising:
- a driving component;
- and
- a helical catheter connected to the driving component,
- wherein, the helical catheter is configured to, prior to the delivery device deploying the perianal fistula closure device:
- hold the suture of the perianal fistula closure device within an interior portion of the helical catheter, and
- hold the anchor of the perianal fistula closure device at an end of the helical catheter such that an insertion point of the anchor protrudes from the end of the helical catheter.
