Abstract
An implant 801 for closing an opening in tissue such as a fistula or a sinus comprises a coil having a substantially uniform outer diameter. The coil forms an internal passage having a diameter that tapers from a distal end to a proximal end. The implant 801 may be delivered using a non-tapered driver coil 820.
Claims19
A method of delivering an implant to an opening in a tissue using a delivery device, the delivery device including a centering member and a handle assembly including a rotary member, the method comprising:
- attaching a seton or suture to the centering member via a centering member loop located at a distal end of the centering member;
- applying tension to the seton or suture via the delivery device;
- centering the delivery device with the centering member with respect to the opening in the tissue based on the tension applied to the seton or suture, the centering member being a separate element from the implant and that extends through the delivery device and through the implant;
- rotating the rotary member of the delivery device in a first direction to rotate the implant and drive the implant into the opening in the tissue;
- and
- rotating the rotary member of the delivery device in a second direction to disengage the implant.
A method of delivering an implant to an opening in a tissue using a delivery device, the delivery device including a driver coil engaging the implant and a handle assembly including a lock and a rotary member, the method comprising:
- attaching a seton or suture to a centering member via a centering member loop located at a distal end of the centering member, the centering member being a separate element from the implant;
- positioning the driver coil of the delivery device and the implant adjacent to the opening in the tissue with the centering member that extends through the delivery device and through the implant;
- centering the seton or suture based on applying tension to the seton or suture via the delivery device;
- unlocking the rotary member by movement of the lock to an unlock position;
- rotating the rotary member of the handle assembly in a first direction to rotate the driver coil and the implant and drive the driver coil and the implant into the opening in the tissue;
- and
- rotating the rotary member of the delivery device in a second direction to disengage the implant from the driver coil and remove the driver coil from the opening of the tissue.
A method of delivering an implant to an opening in a tissue using a delivery device, the delivery device including a rotary member and a one-way rotation mechanism, the method comprising:
- positioning the implant adjacent to the opening in the tissue using the delivery device with a centering member located adjacent to a distal end of the delivery device, the centering member being a separate element from the implant;
- centering a seton or suture by applying tension to the seton or suture via the delivery device after attaching the seton or suture to the centering member via a centering member loop located at a distal end of the centering member;
- unlocking the rotary member by movement of a lock along a longitudinal axis of the delivery device;
- rotating the rotary member of the delivery device in a first direction while prohibiting rotation in a second direction, the rotating of the rotary member in the first direction being for a predetermined number of rotations to rotate the implant, drive the implant into the opening in the tissue, and disengage the one-way rotation mechanism to allow for rotation of the rotary member in the second direction;
- and
- rotating the rotary member of the delivery device in the second direction to disengage the implant from the delivery device and remove the delivery device from the opening of the tissue.
