Catheter tunneler adapter and methods of assembly to a catheter and use
First Claim
1. A catheter tunneling adapter for connection to a proximal end of a catheter, comprising:
- an elongated body having a distal end and a proximal end and a tubular, open passageway extending through the body from the distal end to the proximal end, the passageway having an entrance at the proximal end and an exit at the distal end, and defining a longitudinal axis,wherein the proximal end is adapted to be removably connected to a catheter tunneler,wherein the distal end is adapted to be connected to at least one catheter lumen, andwherein the catheter has a first lumen and a second lumen defined in respective first and second proximal tubes of the catheter, and the adapter further includes a flexible arm that protrudes distally of the distal adapter end, offset laterally from the passageway exit at the distal end, and concludes in an elongate plug adapted to fit sealingly in a proximal end of the second proximal tube of the catheter,whereby the passageway permits insertion of a medical device through the adapter into the at least one catheter lumen when the tunneler is not connected to the adapter.

Abstract
A catheter tunneling adapter including a generally elongated body having a proximal end, a distal end and a through passageway. The proximal end of the adapter is connectable both to a proximal hub of a stylet and subsequently to the distal end of a tunneler. The distal end of the adapter comprises a connector for connecting a plurality of proximal catheter tubes thereto, wherein the proximal end of one tube is affixed within the passageway at the adapter'"'"'s distal end and the proximal end of the second tube is plugged by a plug extending distally from a free end of an elongate flexible arm that also extends distally of the adapter'"'"'s distal end, such that the plug is offset laterally therefrom. The flexible arm and the affixed second tube end are deflectable toward the first tube to reduce the profile of the assembly during tunneling.

16. A catheter tunneling adapter for connection to a proximal end of a multiple lumen catheter, comprising:
-
an elongated body having a distal end and a proximal end and a longitudinal axis extending therethrough between the distal end and the proximal end, wherein the adapter comprises a passageway extending longitudinally through the elongated body from an entrance at the proximal end to an exit at the distal end, wherein the entrance is adapted to be removably connected to a distal end of a catheter tunneler, wherein the exit is adapted to be connected to a first proximal tube of a catheter through which extends a first lumen of the catheter, wherein the adapter further includes a flexible arm that protrudes distally from all other portions of the adapter and offset laterally from the passageway exit, and concludes in an elongate plug adapted to fit sealingly in a proximal end of a second proximal tube of the catheter and thus occlude a second lumen of the catheter. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)

28. A catheter tunneling adapter for connection to a proximal end of a multiple lumen catheter, comprising:
-
an elongated body having a distal end and a proximal end and a longitudinal axis extending therethrough between the distal end and the proximal end, wherein the adapter comprises a passageway extending longitudinally through the elongated body from an entrance at the proximal end to an exit at the distal end, wherein the entrance is adapted to be removably connected to a distal end of a catheter tunneler, wherein the exit is adapted to be connected to a first proximal tube of a catheter through which extends a first lumen of the catheter, wherein the adapter further includes a flexible arm that protrudes distally of the distal adapter end, offset laterally from the distal end, and concludes in an elongate plug adapted to fit sealingly in a proximal end of a second proximal tube of the catheter and thus occlude a second lumen of the catheter, and wherein the flexible arm includes an enlargement proximally of the plug that has a maximum diameter at least as great as an outer diameter of the second proximal tube and defines a distally facing abutment shoulder for abutment with the proximal end of the second proximal tube, and the enlargement is frustoconical increasing in diameter proceeding distally to the plug.
