Abstract
The present invention discloses a vascular access device for hemodialysis, particularly, a transcutaneous access device. The transcutaneous access is optionally connected to one or more subcutaneous blood tubing and one or more sterile connectors which attach to the device and keeps the device sterile from external contamination when not in use. Advantages of the transcutaneous access include the elimination of the need to apply local anesthetic to the patient in order locate the access, the unnecessary bleeding or bruising of the patient and the reduction of total time of the dialysis procedure.
Claims20
A vascular access method for hemodialysis, comprising:
- a) providing by a surgical procedure subcutaneous graft arrangements having a first branch connected to an artery and a second branch connected to a vein;
- b) placing a first transcutaneous access device connected to the first branch of the graft which is further connected to an artery;
- and
- c) placing a second transcutaneous access device connected to the second branch of the graft which is further connected to a vein;
- and
- d) attaching connectors connected to the access devices thereby maintaining the device in a clean sterile environment;
- and
- e) periodically coupling a hemodialysis apparatus to said first and second access devices.
A vascular access method for performance with a hemodialysis apparatus, comprising:
- a) implanting by a surgical procedure a first transcutaneous access device connected to an artery;
- and
- b) implanting by a surgical procedure a second transcutaneous access device connected to a vein.
A vascular access method for performance with a hemodialysis apparatus, comprising:
- providing a first and second transcutaneous access device connected to a first and second subcutaneous blood tubing and whereby the access devices are optionally connected to a first and second connector which maintains the devices in a sterile environment from external contamination until placement of the needle or coupling into the device or the device connector.
