This invention is a subcutaneous implantable dual lumen high flow volume vascular port catheter, designed to rapidly both deliver fluid into and withdraw fluid from the patients bloodstream. Access into the solid based reservoir dual lumens is via a non-coring needle through an anterior non-coring needle penetrable septum. This septum is self-sealing, allowing for multiple repeated non-coring needle placement without leaking. The septum holds and seals the non-coring needle in place during fluid movement. The septum is designed for subcutaneous tactile palpation for localization of non-coring needle placement. The septum has a trough rectangular shape with six windows in which to access the lumens.
Within the base of each of the two lumens are large calibur outlet stems that connect a high pressure catheter from the reservoir lumen through the catheter into the patients bloodstream. Flushing positive pressure through the needle into the reservoir would allow fluids to be sent into the patients blood stream. Visa versa aspiration negative pressure through the needle within the reservoir will allow blood to be removed from the blood stream.
The caliber of the outlet stems and high pressure catheter caliber is specifically designed to allow large volume high flow rates to accommodate for functions such as but not limited to dialysis.
The associated drawings illustrate the invention:
This invention improves implantable dual lumen vascular access port catheters by creating a high volume flow rate, high pressure system with larger caliber reservoir stems and large caliber catheter with six windows septum for needle access. Aside from the standard subcutaneous vascular access port benefits, this design will allow for dialysis vascular access to be performed. Which vascular dialysis demands high flow rate volumes.
The vascular dialysis patients typically receive dialysis access every other day. The repeated subcutaneous needle sticks every other day in the same skin location overlying the standard two window vascular access ports; tend to cause skin breakdown, thinning and high risk of infection. Hence, once the skin is thinned and infection happens, the standard port would need to be removed. This six window port invention would allow for the standard every other day needle access point to be distributed along the skin in a different window location evenly between the six windows; instead of the standard port two skin locations. Hence, allowing for the proper subsequent needle stick adjacent window selection, the same window in this invention would not be needle accessed but once a week; instead of the standard every other day. This would allow sufficient time for the overlying subcutaneous skin to heal fully before the next needle access one week later.
Ideally the purpose of this invention is to allow the patient the option of blood dialysis without the need of surgery to create standard vascular fistulas or graft fistulas. Also, allows for patients who are not and/or no longer surgical candidates to receive blood dialysis via this port catheter invention.
