Embodiment Construction

[0043] First refer to figure 1 , the percutaneous access device includes a main body. The main body may be formed as a single piece, or it may consist of two parts assembled together, namely an upper part 10A and a lower part 10B. In the illustrated embodiment, the lower portion 10B of the body defines a plurality of ports 12 . The body may define any number of ports, such as one port, two ports, three ports, four ports or more. In the embodiment shown, there are six ports. These ports extend into ducts 13 which extend laterally from and away from the body 10 . Such tubing can be connected to an implanted device (not shown).

[0044] To substantially seal port 12 against the ingress of microorganisms, a plug 14 is provided. A plug is positioned on top of the lower portion 10B of the body above the passageway into the port. To hold the bung in place, the upper part 10A of the body is positioned thereon and secured to the lower part of the body, for example by screws 16 . ...

Abstract

Apparatus for delivering therapeutic agents to the central nervous system of a subject is described. The apparatus comprises at least one intracranial catheter and a percutaneous access device (50; 140; 150; 160). The percutaneous access device comprises a body (10; 52; 152) having at least one extracorporeal surface (22; 68) and at least one subcutaneous surface, the body (10; 52) defining at least one port (12; 116) for connection to an implanted intracranial catheter. The port (12; 116) is accessible from the extracorporeal surface (22; 68) of the device, but is provided with a seal (14; 112; 142; 146) such as a rubber bung between the lumen of the port and the extracorporeal surface (22; 68). The percutaneous access device may have more than two ports (12; 116) and / or a flange (26; 54). A method of implanting the percutaneous access device(50; 140; 150; 160) is also described.

Description

technical field [0001] The present invention relates to a percutaneous implant system and, in particular, to a neurological device comprising a percutaneous access device adapted for use with an implanted intracranial catheter. Background technique [0002] Transdermal devices are devices that establish a connection inside and outside the body through the skin. These devices include dental implants, external hearing aids, prosthetic attachments and semi-permanent catheters. These percutaneous devices are fixed into bone and some are fixed into soft tissue. All percutaneous devices protrude beyond the skin, breaking the barrier to infection that is usually provided by the skin. Transdermal devices fail for a number of reasons, including pouching, where epithelial cells are reduced and form a pocket around the device, thereby rejecting the device. More seriously, percutaneous devices are potential sites for infection. Therefore, it is crucial that the junction between the ...
