Multi-function proximal end adapter for catheter
First Claim
1. A multi-function proximal end adapter for a catheter comprising:
- a one-piece body, having proximal and distal ends, defining an axial lumen extending between the proximal and distal ends;
a catheter mounting element for mounting a catheter directly to the body;
a radially compressible seal, having a central bore, positioned within the body along the axial lumen at a distance from the proximal end;
compression means for causing the radially compressible seal to compress inwardly; and
at least part of a proximal end portion of the axial lumen proximal of the seal being defined by an internal tapered surface sized to matingly and sealingly engage an external tapered surface of a Luer lock connector.

Abstract
A multi-function proximal end adapter (70, 86, 100) for a catheter (22) includes a hollow body (6) defining an axial lumen (8) extending between its proximal and distal ends (12, 10). An annular radially compressible seal (48) is positioned within the body along the axial lumen. A seal driver (58) is threadably mounted to the body and has a hollow extension (60) with a distal end adapted to axially compress the seal causing a radially inward deflection of the seal when the seal driver is threaded onto the body thereby providing a good seal against and securement for an object (such as a catheter or guide wire) passing through the axial lumen of the body. At least a portion of the proximal end of the axial lumen is defined by an internal tapered surface (36) sized to matingly and sealingly engage an external tapered surface (44) of a Luer lock connector (40) after the seal driver has been removed from the proximal end of the body.

13. A combination multi-function proximal end adapter and a hollow catheter sleeve comprising:
-
a one-piece body, having proximal and distal ends, defining an axial lumen extending between the proximal and distal ends; a hollow catheter secured within and extending from the axial lumen at the distal end of the body, the hollow catheter defining a main, axially extending lumen and at least one secondary, radially offset, axially extending lumen, the secondary lumen including an entrance port opening into a first portion of the axial lumen of the body; the body further comprising a side branch having a side port fluidly connected to the entrance port though a second portion of the axial lumen; a radially compressible seal, having a central bore, positioned within the body along the axial lumen at a distance from the proximal end; compression means for causing the radially compressible seal to compress inwardly, the compression means comprising; a seal driver, having a first thread; the body having a second thread engageable with the first thread; and the seal driver including a hollow extension having a distal end adapted to axially compress, thereby radially inwardly deflecting, the seal when the first thread threadably engages the second thread; and at least part of a proximal end portion of the axial lumen proximal of the seal being defined by an internal tapered surface sized to matingly and sealingly engage an external tapered surface of a Luer lock connector.

14. A method for use of a proximal end adapter of a catheter, the adapter having a one-piece body with an axial lumen extending between the proximal and distal ends of the body, the axial lumen defined in part by an internal tapered surface located towards the proximal end, comprising the following steps:
-
mounting a first connector, having an external tapered surface, to the proximal end of the one-piece body with the external tapered surface matingly engaging the internal tapered surface to provide a fluid seal therebetween; conducting a first procedure using the first connector; removing the first connector from the proximal end of the body; threadably mounting a second connector to the proximal end of the body; and threadably adjusting the engagement of the second connector on the proximal end of the body thereby causing a resilient annular seal housed within the axial lumen to deflect radially inwardly and sealingly engage a device passing through the axial lumen. - View Dependent Claims (15, 16, 17, 18, 19)
