Percutaneous access apparatus (12) is described that comprises a percutaneous fluid access device (100) having an extracorporeal portion (106), one or more ports (120) accessible from the extracorporeal portion and a septum (122) for sealing each port. A connector device (130) comprising one or more hollow needles (182) is attachable to the percutaneous fluid access device. The apparatus also includes an attachment mechanism (132) for attaching the connector device (130) to the extracorporeal portion (106) and an actuation mechanism that, after the connector device (130) has been attached to the extracorporeal portion (106), can be used to drive the one or more hollow needles (182) through the septum (122) to establish fluid communication between the one or more hollow needles (182) and the one or more ports (120). The apparatus may be used for neurosurgery applications.

A multi-instrument sealing mechanism is provided. The multi-instrument sealing mechanism includes a cannula seal, a cannula cap, an instrument guide, an instrument seal, and door mechanisms in the instrument guide. The cannula seal can include a cross-slit seal. The cannula cap can capture the cannula seal between the instrument guide and the cannula. A door mechanism and instrument seal can be housed in the instrument guide.
摘要:
A skull mountable,implantable percutaneous fluid delivery device (2; 52; 82; 02) is described for use in delivering fluids to target sites in the brain. The device (2; 52; 82; 102) includes a subcutaneous base portion (6; 56; 86) comprising one or more ports for supplying fluid to one or more implanted catheter devices (18). A percutaneous portion (4; 54; 84; 104) of the device comprises an extracorporeal surface (10), the one or more ports of the subcutaneous base portion (6; 56; 86; 106) being accessible from the extracorporeal surface (10) of the percutaneous portion(4; 54; 84; 104). The subcutaneous base portion (6; 56; 86) is at least partially insertable into a complementary recess formed in a bone (44; 140) and comprises one or more anchoring features comprising at least one radially protruding wing (24; 62; 88; 124) for directly anchoring the subcutaneous base portion (6; 56; 86;106) to the bone (44; 140).

摘要:
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.
