1. Apparatus for anchoring a catheter to the body of an individual, said apparatus comprising, in combination:
- a substantially rigid attachment member forming a substantially circular closed loop having a substantially uniform first radius of curvature and defining a substantially round opening extending through said closed loop, said attachment member having substantially uniformly curved over-lapping ring portions in registry with each other, one of said ring portions having a first free end and the other of said ring portions have a second free end, said first and second free ends being adjacent to one another with each free end positioned alongside and in close proximity to a ring portion and not projecting away from said closed loop; and
a surgical needle integral with said attachment member and detachably connected to said attachment member at one of the free ends of said attachment member and projecting outwardly from and gradually diverging away from said attachment member from the free end to which said surgical needle is detachably connected, said surgical needle having a pointed distal end spaced from said attachment member for piercing the skin of an individual to attach said apparatus to the body of the individual, said surgical needle being smoothly curved over the length thereof and having a second radius of curvature larger than said first radius of curvature, and said surgical needle being in partial registry with said attachment member.

Abstract
A system for anchoring a catheter to the body of an individual wherein one or more rigid attachment members forming closed loops are secured to the body by detachable surgical needles. A catheter mounting member is connected to the attachment member or attachment members to engage a catheter and restrict movement of the catheter relative to the attachment member or members and relative to the individual.

4. Apparatus for anchoring a catheter to the body of an individual, said apparatus comprising, in combination:
-
a substantially rigid attachment member forming a substantially circular closed loop having a substantially uniform radius of curvature and defining a substantially round opening extending through said closed loop, said attachment member for passing through the skin of an individual at spaced skin locations to secure said attachment member to the individual with a segment of the attachment member located above the skin and a segment of the attachment member located below the skin, said attachment member having closely adjacent curved over-lapping ring portions in registry with each other, one of said ring portions having a first free end and the other of said ring portions having a second free end, said first and second free ends being adjacent to one another with each free end positioned alongside and in close proximity with a ring portion and not protecting away from said closed loop; and a catheter mounting member for connection to said attachment member and for passing through the opening of said attachment member above the skin of the individual to whom the attachment member is secured, said catheter mounting member for engaging a catheter, for interconnecting said attachment member and said catheter, and for restricting movement of said catheter relative to said attachment member and relative to the individual. - View Dependent Claims (5, 6, 7, 8)
