Abstract
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.
Claims20
An interventional device delivery system, comprising:
- a handle assembly comprising:
- a catheter holder, the catheter holder having a passageway therethrough;
- a flush block associated with the catheter holder, the flush block having a flush port and a flush chamber, the flush chamber being in fluid communication with the flush port and the passageway in the catheter holder;
- a delivery member associated with the handle assembly, the delivery member comprising a plurality of catheters, at least one catheter of the plurality of catheters having a proximal end disposed within the passageway in the catheter holder and being in fluid communication with the flush chamber.
An interventional device delivery system, comprising:
- a handle assembly comprising:
- a delivery catheter holder, the delivery catheter holder having a passageway therethrough;
- a suture catheter holder associated with the delivery catheter holder;
- a flush block associated with the suture catheter holder, the flush block having a flush port and a flush chamber, the flush chamber being in fluid communication with the flush port and the passageway in the suture catheter holder;
- and
- a gasket assembly closing a proximal end of the flush block, a guide wire tube and a suture extending through the gasket assembly, the suture connecting an interventional device to the handle assembly;
- a delivery member associated with the handle assembly, the delivery member comprising a plurality of catheters, at least one catheter of the plurality of catheters having a proximal end disposed within the passageway in the catheter holder and being in fluid communication with the flush chamber.
An interventional device delivery system, comprising:
- a delivery member associated with a handle assembly,
- wherein, the delivery member comprises:
- a guidewire tube having a guidewire lumen;
- a suture catheter which receives the guidewire tube, the suture catheter having at least one suture lumen for receiving a suture that connects the handle assembly to an interventional device at a distal end of the delivery member;
- a delivery catheter disposed about both the suture catheter and the guidewire tube;
- and
- an outer sheath disposed about the delivery catheter, and
- wherein, the handle assembly comprises:
- a suture catheter holder having a passageway therethrough, a proximal end of the suture catheter being disposed within the passageway in the suture catheter holder;
- a flush block associated with the suture catheter holder, the flush block having a flush port and a flush chamber, the flush chamber being in fluid communication with the flush port and the passageway in the suture catheter holder;
- a gasket assembly closing off a proximal end of the flush chamber, the guidewire tube and a suture passing through the gasket assembly.
