ABSTRACT:
An implantable subcutaneous set for mounting onto a skin of a user and contacting a subcutaneous placement site beneath the skin includes a base, a cannula, an insertion device and an externally extending conduit. The base is used to secure the implantable subcutaneous set to the skin of the user. The cannula is coupled to and extends from the base. Also, the cannula has at least one lumen with an end for fluid communication with the subcutaneous placement site. In addition, the cannula has at least one port formed near another end of the lumen opposite the end for fluid communication. The insertion device is operatively coupled to the implantable subcutaneous set and the cannula to facilitate insertion of the cannula to contact the subcutaneous placement site. Also, the insertion device may be withdrawn from the subcutaneous set and the cannula after placing the cannula in contact with the subcutaneous placement site. The externally extending conduit is in fluid communication with the at least one port of the cannula to facilitate removal of a fluid that builds up around the at least one lumen of the cannula after insertion of the cannula to substantially prevent degradation of performance of the implantable subcutaneous set while in contact with the subcutaneous placement site. The build up of the fluids are bodily fluids of the user that pool around the port in the at least one lumen of the cannula, and the pool of fluids degrades the performance of the implantable subcutaneous set by obscuring access of other bodily fluids to the at least one lumen of the cannula.
