Abstract
Anchors for securing a medical device relative to a body portal, wherein the anchors may accommodate most any implantation trajectory through the portal. Such anchors may further secure the device along any such trajectory without imparting undesirable biasing forces that may shift the device from its intended implanted location. In some embodiments, the anchor is configured as a burr hole anchor including a spherical member contained in a socket of the anchor such that orientation of the spherical member is permitted about three mutually perpendicular axes.
Claims21
1-27. (canceled)
An infusion system comprising:
- a therapy catheter implantable through a burr hole, the therapy catheter comprising a therapy delivery end configured to be positioned at a target tissue location;
- a delivery catheter operable to deliver a therapeutic agent, from a source containing the therapeutic agent, to the therapy catheter;
- a connector configured to fluidly couple the therapy catheter with the delivery catheter;
- and
- an anchor comprising:
- a base configured to secure to bone surrounding the burr hole, the base comprising an upper side, lower side, outer edge, and inner edge, the inner edge defining an opening passing between the upper and lower sides, the opening forming a socket;
- and
- a spherical member configured to be received within the socket such that the spherical member may rotate therein about three mutually perpendicular axes, the spherical member defining a bore formed therein, the bore configured to receive both a first end of the therapy catheter and a first end of the connector when the first end of the connector is fluidly coupled to the therapy catheter.
An infusion system comprising:
- a therapy catheter implantable through a burr hole, the therapy catheter comprising a therapy delivery end configured to be positioned at a target tissue location;
- a delivery catheter operable to deliver a therapeutic agent, from a source containing the therapeutic agent, to the therapy catheter;
- a connector configured to fluidly couple the therapy catheter with the delivery catheter;
- and
- an anchor comprising:
- a base configured to secure to bone surrounding the burr hole, the base comprising an upper side, lower side, outer edge, and inner edge, the inner edge defining an opening passing between the upper and lower sides, wherein the opening forms a socket;
- and
- an elastomeric spherical member configured to be received within the socket such that the spherical member may rotate therein, the spherical member defining a bore formed therethrough, the bore configured to permit passage of the therapy catheter through the base from the upper side to the lower side, the spherical member configured to immobilize the therapy catheter via application of a radial compression force applied to the therapy catheter.
