Abstract
Methods of declotting vascular access technologies, such as vascular access assemblies that facilitate hemodialysis, are provided. The methods can include disposing a catheter within a patient to access a vascular access assembly within the heart of the patient. The catheter can be coupled to the vascular access assembly such that a clot can be evacuated from within the vascular access assembly via the catheter.
Claims20
A method of declotting a vascular access assembly within a patient, the method comprising:
- inserting a central end portion of a catheter into the patient such that the central end portion of the catheter is disposed within the vasculature of the patient;
- coupling the central end portion of the catheter to a central end portion of a vascular access assembly disposed within the vasculature of the patient,
- wherein the vascular access assembly is completely disposed within the patient, and
- wherein the coupling occurs within the vasculature of the patient;
- and
- evacuating a clot from within a portion of the vascular access assembly via the catheter.
A method of removing a clot from a vascular access assembly within a patient, the method comprising:
- accessing an internal jugular vein of the patient;
- inserting a central end portion of a catheter into the internal jugular vein;
- displacing the catheter such that the central end portion of the catheter is disposed within a vena cava or right atrium of a heart of the patient;
- coupling the central end portion of the catheter to a central end portion of a vascular access assembly disposed within the vena cava or right atrium,
- wherein the vascular access assembly is a fully subcutaneous implant, and
- wherein the coupling occurs within the vena cava or right atrium;
- and
- evacuating a clot from within a portion of the vascular access assembly via the catheter.
A method of removing a clot from a vascular access assembly within a patient, the method comprising:
- accessing a femoral vein of the patient;
- inserting a central end portion of a catheter into the femoral vein;
- displacing the catheter such that the central end portion of the catheter is disposed within a vena cava or right atrium of a heart of the patient;
- coupling the central end portion of the catheter to a central end portion of a vascular access assembly disposed within the vena cava or right atrium,
- wherein the vascular access assembly is a fully subcutaneous implant, and
- wherein the coupling occurs within the vena cava or right atrium;
- and
- evacuating a clot from within a portion of the vascular access assembly via the catheter.
