Methods, systems, and devices for sealing and flushing a delivery system
A method for sealing and flushing a delivery member includes sealing one or more lumens and flushing air from the one or more lumens. An interventional device delivery system includes a handle assembly and a delivery member. The handle assembly includes a catheter holder with a passageway therethrough. A flush block is associated with the catheter holder and has a flush port and a flush chamber. The delivery member is associated with the handle assembly and includes a plurality of catheters. At least one of the catheters has a proximal end disposed within the passageway in the catheter holder and is in fluid communication with the flush chamber.
1. A method for sealing and flushing a delivery member, the method comprising:
sealing one or more lumens of the delivery member including sealing a suture lumen of a suture catheter that is configured to receive a suture that connects a handle assembly of the delivery member to an interventional device at a distal end of the delivery member, a guidewire tube having one of the one or more lumens and the suture passing through a gasket assembly that closes a flush block connected to a suture catheter holder; and
flushing a fluid from the one or more lumens.
2. The method of claim 1 , further comprising sealing the delivery member in a container and filling the container with CO 2 .
3. The method of claim 1 , wherein sealing the one or more lumens comprises sealing each of the one or more lumens with a flush port.
4. The method of claim 3 , wherein following the flushing of the fluid from the one or more lumens comprises closing the flush port to retain a flushing fluid or gas within the one or more lumens.
5. The method of claim 4 , further comprising sealing the delivery member in a container.
6. A method for sealing and flushing a delivery member,
the method comprising:
sealing a guide wire lumen of a guidewire tube;
sealing at least one suture lumen of a suture catheter that is received by a handle assembly, the suture catheter receives the guidewire tube having the guide wire lumen, the at least one suture lumen receiving a suture that connects the handle assembly to an interventional device at a distal end of the delivery member, the guidewire tube and the suture passing through a gasket assembly that closes a flush block connected to the suture catheter holder;
sealing a delivery catheter disposed about both the suture catheter and the guidewire tube having the guide wire lumen;
sealing an outer sheath disposed about the delivery catheter; and
flushing a fluid from the guide wire lumen, the at least one suture lumen, a lumen associated with the delivery catheter, and a lumen of the outer sheath.
7. The method of claim 6 , wherein the flushing of the fluid comprises flushing using CO 2 .
8. The method of claim 6 , wherein the flushing of the fluid comprises flushing using a saline solution.
9. The method of claim 6 , further comprising connecting a port to at least one of the guide wire lumen, the at least one suture lumen, the lumen associated with the delivery catheter, and the lumen of the outer sheath.
10. The method of claim 6 , further comprising sealing the delivery member in a container and filling the container with CO 2 .
11. The method of claim 6 , wherein the sealing at least one of the guide wire lumen, the at least one suture lumen, the lumen associated with the delivery catheter, and the lumen of the outer sheath comprises sealing each with one or more flush ports or valves.
12. The method of claim 11 , wherein following the step of flushing the fluid from the at least one of the guide wire lumen, the at least one suture lumen, the lumen associated with the delivery catheter, and the lumen of the outer sheath, the method further comprises closing the one or more flush ports or valves to retain a flushing fluid or gas within the at least one of the guide wire lumen, the at least one suture lumen, the lumen associated with the delivery catheter, and the lumen of the outer sheath.
13. The method of claim 12 , further comprising sealing the delivery catheter in a container.
