ERCP catheter with a removable handle for lithotriptor compatible basket

An apparatus comprising:

• a catheter;
• a connector attached to the catheter;
• and
• a removable handle assembly attached to the connector;
• a drive cable having a proximal end, a distal end and a basket assembly formed at the drive cable distal end and a coating along at least a portion of the drive cable proximal the basket assembly;
• wherein the catheter further comprises a catheter drive cable lumen,
• wherein the connector further comprises a connector drive cable lumen axially aligned with the catheter drive cable lumen and an injection port;
• wherein the removable handle assembly comprises a handle lumen axially aligned with the connector drive cable lumen, a control handle member slidably and detachably associated with a gripping handle member, a tightening mechanism and a detachable cable loop;
• wherein the drive cable extends through the catheter drive cable lumen, the connector drive cable lumen, the handle lumen, the control handle member, the gripping handle member, the tightening mechanism and into the detachable cable loop;
• wherein the tightening mechanism releasably affixes the axial position of the drive cable relative to the control handle member such that axial movement of the control handle member relative to the gripping handle member drives the drive cable and causes the basket assembly to expand and collapse as the basket assembly moves into and out of the catheter.

An apparatus comprising:

• a multi-lumen catheter;
• a multi-port connector attached to the multi-lumen catheter;
• a removable handle assembly attached to the multi-port connector;
• a drive cable having a proximal end, a distal end and a basket assembly formed at the drive cable distal end and a coating along at least a portion of the drive cable proximal the basket assembly;
• a wire guide;
• wherein the multi-lumen catheter comprises a catheter drive cable lumen and a wire guide lumen;
• wherein the multi-port connector further comprises a connector drive cable lumen axially aligned with the catheter drive cable lumen, a connector wire guide lumen axially aligned with the catheter wire guide lumen, a wire guide port in fluid communication with the connector wire guide lumen and an injection port in fluid communication with the connector wire guide lumen;
• wherein the wire guide extends through the catheter wire guide lumen, the connector wire guide lumen and exits the wire guide port;
• wherein the removable handle assembly comprises a handle lumen axially aligned with the connector drive cable lumen, a control handle member slidably and detachably associated with a gripping handle member, a tightening mechanism and a detachable cable loop;
• wherein the drive cable extends through the catheter drive cable lumen, the connector drive cable lumen, the handle lumen, the control handle member, the gripping handle member, the tightening mechanism and into the detachable cable loop;
• wherein the tightening mechanism releasably affixes the axial position of the drive cable relative to the control handle member such that axial movement of the control handle member relative to the gripping handle member drives the drive cable and causes the basket assembly to expand and collapse as the basket assembly moves into and out of the catheter.
