Method and apparatus for administration of fluids

Claim 1

An integrated transcutaneous fluid delivery system which comprises: a fluid receptacle for subcutaneous surgical implantation in a living body, said receptacle including a walled reservoir, penetrable resealable inlet means for adding fluid to said reservoir, and outlet means for delivering fluid from said reservoir to selected sites in the body; an elongated hollow fluid delivery conduit adapted at one end thereof for supercutaneous connection to a supply of the fluid, an other end thereof being adapted for subcutaneous penetration of said inlet means; together with anchor means for securing said conduit on the body including a resilient protective boot including a plurality of concentric annular rings having inside and outside peripheries and stacked using said conduit as an axis beginning with a base ring carrying adhesive for attachment to the body, and ending with a terminal ring to be attached to said conduit, each annular ring in the stack being flexibly joined to the next adjacent ring alternately at said inside and outside peripheries to provide shock-absorbing extension and compression along said axis, and providing means, when said terminal ring and said conduit are attached, to urge said protective boot into a compressed state along said axis, thereby urging said conduit into said reservoir; whereby implanting said receptacle, penetrating said inlet means with said conduit, and securing said conduit on the body permits long-term infusion of the selected sites with the fluid.

Claim 12

A method for the long-term delivery of a therapeutic fluid to selected sites within a living body which comprises: implanting in the body a fluid receptacle including a walled reservoir, penetrable resealable inlet means for adding fluid to the reservoir, and outlet means for delivering fluid from the reservoir to the selected sites; penetrating said inlet means with one end of an elongated hollow fluid delivery conduit adapted at an other end thereof for supercutaneous connection to a supply of the fluid; securing said conduit on the body with an anchor which includes a resilient protective boot including a plurality of concentric annular rings having inside and outside peripheries and stacked using said conduit as an axis, beginning with a base ring carrying adhesive for attachment to the body, and ending with a terminal ring attached to said conduit, each annular ring in the stack being flexibly joined to the next adjacent ring alternately at inside and outside peripheries to provide shock-absorbing extension and compression along said axis, and providing means to urge said protective boot into a compressed state along said axis, thereby urging said conduit into said reservoir; and connecting said conduit to a supply of the fluid.

Claim 13

A method for the long-term delivery of a therapeutic fluid to selected sites within a living body which comprises: implanting in the body a fluid receptacle including a walled reservoir, penetrable resealable inlet means for adding fluid to the reservoir, and outlet means for delivering fluid from the reservoir to the selected sites; penetrating said inlet means with one end of an elongated hollow fluid delivery conduit adapted at an other end thereof for supercutaneous connection to a supply of the fluid; securing said conduit on the body with an anchor which includes a resilient protective boot including a plurality of concentric annular rings having inside and outside peripheries and stacked using said conduit as an axis, beginning with a base ring carrying adhesive for attachment to the body, and ending with a terminal ring attached to said conduit, each annular ring in the stack being flexibly joined to the next adjacent ring alternately at inside and outside peripheries to provide shock-absorbing extension and compression along said axis, and providing means to urge said protective boot into a compressed state along said axis, thereby urging said conduit into said reservoir; and connecting said conduit to a supply of the fluid.
