Port with conduit wraparound feature

摘要

An injection port includes a port body having a fluid reservoir and a connector in fluid communication with the reservoir. The injection port further includes a conduit protection feature that is configured to protect against kinking of the conduit, decoupling of the conduit from the connector, or penetration of the conduit by a needle. The protection feature may include an anchor for anchoring the conduit to tissue to reduce conduit movement. The protection feature may include a recess that is configured to receive part of the conduit. The protection feature may include a bend formed in the connector to reduce transverse stresses in the conduit. The protection feature may include a bell-shaped shroud encompassing the connector. A sleeve may further protect the conduit and/or the coupling between the connector and the conduit.

主权项

1. An apparatus, comprising:
(a) a port body, wherein a sidewall of the port body defines a fluid reservoir, wherein the port body is sized and configured for implantation in a patient; (b) a connector extending outwardly from the port body in a first direction, wherein the connector is in fluid communication with the reservoir, wherein the connector is configured to couple with a conduit for communicating fluid between the conduit and the reservoir via the connector; and (c) a conduit protection feature integrated with the port body, wherein the conduit protection feature comprises an arcuate recess formed in an exterior surface of the sidewall of the port body into which the conduit is removably disposed and a plurality of tabs in an alternating arrangement along the top and bottom of the recess, wherein the tabs and recess are configured such that the conduit must be compressed or deformed to fit into the recess, thereby providing friction between the conduit and the tabs and the recess that substantially resists sliding of conduit in the recess, wherein the recess extends radially inwardly into the sidewall of the port body, wherein the conduit protection feature is configured to guide the conduit in a second direction transverse to the first direction, and wherein the conduit protection feature is configured to protect against one or more of the following conditions:
(i) kinking of the conduit after the conduit is coupled with the connector and after the port body is implanted in a patient,(ii) decoupling of the conduit from the connector after the conduit is coupled with the connector and after the port body is implanted in a patient, and(iii) penetration of the conduit adjacent to the port body by a needle after the conduit is coupled with the connector and after the port body is implanted in a patient.
