Abstract:
According to various embodiments, a method and system to obtain access to a blood vessel underneath a skin layer that may preserve lifespan of the blood vessel and reduce executional skill variability may be provided. The method includes placing a guiding portion between the blood vessel and the skin layer; and configuring the guiding portion to receive and guide a needle to reach the same location of the blood vessel repeatedly and consistently; and forming a resultant scarred track between the blood vessel and the skin layer as the guiding portion is resorbed over time. The system includes a vascular access device configurable to first possess strength to penetrate through a tissue layer, subsequently possess flexibility to conform to the surrounding tissue beneath the tissue layer; and a guiding portion which may be resorbable, wherein the inlet includes a larger diameter compared to the outlet.
Abstract:
A subcutaneous implantable device for guiding a vascular access member, the device including a channel defined by a through-hole in the device, wherein the channel is configured to guide the vascular access member there-through to a vascular site; and anchoring means adapted for fixedly attaching, in a form of using suture, tissue ingrowth, tissue encapsulation or tissue adhesion, the device io at least one of a dermis or a subcutaneous tissue at a position underneath the dermis to allow repeated access of the vascular access member through the channel to the vascular site, wherein the device is dimensioned to allow the device to be attached through the anchoring means for anchoring the entire device at a distance away from the vascular site, A method of creating scar tissue track for vascular access is also disclosed where the subcutaneous implantable device for guiding vascular access member is first implanted sub-dermally, the dermis is palpated to feel for the device location and orientation, the guiding channel is accessed using the sharp vascular access member and following the angle of the guiding channel to access the vascular site and repeating the steps till scarred tissue track is created and finally, switching the sharp vascular access member to a blunt vascular access member to access the vascular site via the scarred tissue track.
Abstract:
According to embodiments of the present invention, a subcutaneous implant delivery apparatus is provided. The apparatus includes a receiving portion configured to receive a subcutaneous implantable device; and a stabilizing portion configured to cooperate with the receiving portion to hold the subcutaneous implantable device in a fixed position. The receiving portion and the stabilizing portion are movable relative to each other between a released configuration, wherein the receiving portion and the stabilizing portion are configured to move apart from each other to allow the receiving portion to be inserted under a skin layer, and a closed configuration, wherein the receiving portion and the stabilizing portion are configured to move toward each other to allow the subcutaneous implantable device to be held adjacent to the skin layer. According to further embodiments of the present invention, a method of delivering a subcutaneous implantable device for accessing a vascular site is also provided.
