Body portal anchors and systems

摘要

Anchors for securing a therapy device such as a therapy catheter relative to a burr hole, and systems and methods for using the same. Anchors in accordance with embodiments of the present disclosure may include a connector for securing the therapy catheter to a delivery catheter, wherein the connector is independently and removably attachable to the anchor. The connector may secure the therapy catheter relative to the burr hole and isolate forces that may otherwise tend to disrupt the placement of the therapy catheter.

主权项

1. An infusion system comprising:
a therapy catheter defining a lumen; and a burr hole anchor comprising:
an annular base defining a central opening and an outer peripheral edge, the base operable to secure to bone surrounding a burr hole, wherein the base defines a catheter connection channel extending from the central opening outwardly through the peripheral edge, wherein the channel is at least partially defined by cinching surfaces configured to mechanically capture a terminal segment of the therapy catheter;a tubular connector selectively insertable into the channel, wherein the connector comprises a therapy tip such that, when the connector is fully inserted into the channel, the therapy tip is received within the lumen of the therapy catheter; anda retaining member positionable within an opening formed in the base, the opening intersecting the channel, wherein the retaining member is movable within the opening, while the connector is fully inserted into the channel, between: a disengaged position, wherein the retaining member is spaced-apart from the connector; and an engaged position, wherein the retaining member passes through the channel such that the retaining member contacts the connector and immobilizes the connector relative to the base.
