Releasable conduit connectors
Systems and methods of implanting a vascular access technologies and declotting vascular access technologies, such as vascular access assemblies that facilitate hemodialysis, are provided. The methods can include disposing a first tubular conduit within a patient to access a vascular access assembly within the heart of the patient. The first tubular conduit can be coupled to the vascular access assembly such that the first tubular conduit can be decoupled from the vascular access assembly to evacuate a clot within the vascular access assembly, and then recouple the first tubular conduit to the vascular access assembly.
1. A vascular access system, comprising:
a first tubular conduit having a central end portion coupled to a body lumen of a patient and a peripheral end portion;
a second tubular conduit having a peripheral end portion coupled to a vessel of the patient and a central end portion; and
a releasable connector having at least a first portion and a second portion, the first portion coupled to the peripheral end portion of the first tubular conduit and the second portion coupled to the central end portion of the second tubular conduit, such that when the first portion and the second portion of the releasable connector are coupled a flow path extends from the vessel to the body lumen via the first and second tubular conduits,
wherein the releasable connector is configured to decouple from at least one of the first tubular conduit and the second tubular conduit,
wherein the releasable connector comprises a ring structure extending radially outward from the exterior surface of the releasable connector and includes one or more holes spaced radially apart and configured for tying a suture to one of the holes of the releasable connector.
2. The vascular access system of claim 1 , wherein the releasable connector is configured to recouple the first portion to the first tubular conduit and the second portion to the second tubular conduit after decoupling the first portion from the first tubular conduit and the second portion from the second tubular conduit.
3. The vascular access system of claim 1 , wherein the first tubular conduit is resistant to kinking and/or crush forces.
4. The vascular access system of claim 1 , wherein the releasable connector comprises at least one connector area where a suture is configured to couple at least one of said tubular conduits to the releasable connector.
5. A vascular access system, comprising:
a first tubular conduit having a central end portion coupled to a body lumen of a patient and a peripheral end portion;
a second tubular conduit having a peripheral end portion coupled to a vessel of the patient and a central end portion;
a releasable connector having at least a first portion and a second portion, the first portion coupled to the peripheral end portion of the first tubular conduit and the second portion coupled to the central end portion of the second tubular conduit, such that when the first portion and the second portion of the releasable connector are coupled a flow path extends from the vessel to the body lumen via the first and second tubular conduits; and
a releasable connection portion that includes a first portion and a second portion connected via a hinge and comprises an open configuration and a locked configured,
wherein in the locked configuration, the first portion and the second portion form a ring to secure the first tubular conduit or the second tubular conduit to the releasable connector by encircling the first tubular conduit or the second tubular conduit and the releasable connector, and
wherein the first portion and the second portion are each releasable independent of the other.
6. The vascular access system of claim 5 , wherein the releasable connector is configured to recouple the first portion to the first tubular conduit and the second portion to the second tubular conduit after decoupling the first portion from the first tubular conduit and the second portion from the second tubular conduit.
7. The vascular access system of claim 5 , wherein the first tubular conduit is resistant to kinking and/or crush forces.
8. The vascular access system of claim 5 , wherein the releasable connector comprises a structure extending outwardly from the exterior surface of the releasable connector configured for tying a suture to the releasable connector.
9. The vascular access system of claim 5 , wherein the releasable connector comprises at least one connector area where a suture is configured to couple at least one of said tubular conduits to the releasable connector.
