Regional anesthesia catheter with anchor
First Claim
1. A catheter for accessing an internal body region, the catheter comprising:
- a catheter body;
a medication lumen positioned within the catheter body for delivering a medication to the internal body region;
an inflation lumen positioned within the catheter body;
a balloon in fluid communication with the inflation lumen, the balloon configured to move between a collapsed position and an expanded position as fluid enters the balloon through the inflation lumen;
an anchor covering at least a portion of the balloon on an outer surface of the catheter body, the anchor includes a plurality of movable sections configured to move between a first retracted position and a second deployed position, each anchor having a first connection to the catheter body distal to the balloon and a second connection to the catheter body proximal to the balloon; and
wherein upon inflation of the balloon, the plurality of movable sections move radially outward from the first retracted position to the second deployed position to secure the catheter in the internal body region.

Abstract
Embodiments of the invention provide a system and method for accessing an internal body region using a catheter. The catheter includes a catheter body and a medication lumen positioned within the catheter body for delivering medication to the internal body region. An inflation lumen is positioned within the catheter body. A balloon is in fluid communication with the inflation lumen, and the balloon is configured to move between a collapsed position and an expanded position as fluid enters the balloon through the inflation lumen. An anchor covers at least a portion of the balloon on an outer surface of the catheter body and includes a movable section with a first retracted position and a second deployed position. Upon inflation of the balloon, the movable section of the anchor moves radially outward from the first contracted position to the second deployed position to secure the catheter in the internal body region.

15. A method for securing a catheter in an internal body region, the method comprising:
- the catheter comprising a catheter body and an anchor including a plurality of movable sections configured to move between a first retracted position and a second deployed position, each anchor having a first connection to the catheter body distal to the balloon and a second connection to the catheter body proximal to the balloon;
inserting the catheter body into the internal body region;
delivering a medication to the internal body region through a medication lumen positioned within the catheter body; and
inflating a balloon surrounding the catheter body from a collapsed position to an expanded position as fluid enters the balloon through an inflation lumen in fluid communication therewith, wherein upon inflation of the balloon, the plurality of movable sections are configured to move from the first retracted position to the second deployed position, to cause the plurality of movable sections to move radially outward to secure the catheter in the internal body region. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22)
