Conduit anchor adapted to receive stylet

Claim 2

In an anchor for an elongated hollow transcutaneous fluid delivery conduit which includes a resilient protective boot having a plurality of concentric annular rings with inside and outside peripheries and stacked using said conduit as an axis beginning with a base ring carrying adhesive for attachment to the skin of a living body and ending with a terminal ring to be attached to said conduit, each ring in said stack being flexibly connected to the next adjacent ring alternately at said inside and outside peripheries to provide shock-absorbing extension and compression along said axis, and including means, when said terminal ring is attached to said conduit, to urge said protective boot into a compressed state along said axis and said conduit into said body, the improvement therein which comprises providing a penetrable resealable septum in said anchor for inserting a stylet into said anchor and through said hollow conduit.

Claim 3

The anchor of claim 1 wherein said terminal ring is attached to a coupling which can be joined to said conduit and said septum is affixed in said coupling to allow for stylet insertion into said conduit.

Claim 4

The anchor of claim 2 wherein said coupling is a 90 degree releasable male/female fitting.

Claim 5

A transcutaneous fluid delivery system which comprises: (a) a fluid receptacle for subcutaneous surgical implantation in a living body, said receptacle including fluid inlet and outlet means; (b) an elongated hollow fluid delivery conduit adapted at one end for supercutaneous connection to a supply of the fluid, an other end thereof being adapted for subcutaneous penetration of said receptacle; together with (c) an anchor for securing said conduit on the body which includes a resilient protective boot having a plurality of concentric annular rings with inside and outside peripheries and stacked using said conduit as an axis beginning with a base ring carrying adhesive for attachment to the skin of the body and ending with a terminal ring to be attached to said conduit, each ring in said stack being flexibly connected to the next adjacent ring alternately at said inside and outside peripheries to provide shock-absorbing extension and compression along said axis, and including means, when said terminal ring is attached to said conduit, to urge said protective boot into a compressed state along said axis and said conduit into said body, together with a penetrable resealable septum in said anchor for inserting a stylet into said anchor and through said hollow conduit.

Claim 6

A transcutaneous fluid delivery system which comprises: (a) a fluid receptacle for subcutaneous surgical implantation in a living body, said receptacle including fluid inlet and outlet means; (b) an elongated hollow fluid delivery conduit adapted at one end for supercutaneous connection to a supply of the fluid, an other end thereof being adapted for subcutaneous penetration of said receptacle; together with (c) an anchor for securing said conduit on the body which includes a resilient protective boot having a plurality of concentric annular rings with inside and outside peripheries and stacked using said conduit as an axis beginning with a base ring carrying adhesive for attachment to the skin of the body and ending with a terminal ring to be attached to said conduit, each ring in said stack being flexibly connected to the next adjacent ring alternately at said inside and outside peripheries to provide shock-absorbing extension and compression along said axis, and including means, when said terminal ring is attached to said conduit, to urge said protective boot into a compressed state along said axis and said conduit into said body, together with a penetrable resealable septum in said anchor for inserting a stylet into said anchor and through said hollow conduit.

Claim 7

The fluid delivery system of claim 4 wherein said terminal ring of said anchor is attached to a coupling which can be joined to said conduit and said septum is affixed in said coupling to allow for stylet insertion into said conduit.

Claim 8

The fluid delivery system of claim 5 wherein said coupling is a 90 degree releasable male/female fitting.

Claim 11

The method of claim 7 wherein said terminal ring of said anchor is attached to a coupling which can be joined to said conduit and said septum is affixed in said coupling to allow for stylet insertion into said conduit.

Claim 12

The method of claim 8 wherein said coupling is a 90 degree male/female fitting.

Claim 13

The method of claim 7 which further comprises inserting a stylet into said anchor and through said hollow conduit prior to penetrating said receptacle.
