Catheter assembly with cuff deployment device
First Claim
1. A catheter assembly, comprising:
- a catheter having an elongate tubular body with an external surface and defining a lumen extending from an open proximal end of the elongate tubular body to an open distal end of the elongate tubular body;
a cuff deployment device concentrically supported on the elongate tubular body and movable along a longitudinal axis of the elongate tubular body, wherein the cuff deployment device includes a deployment mechanism having an actuated position and a non-actuated position;
a cuff having a hollow cylindrical body defining an internal catheter engagement surface for contacting the external surface of the elongate tubular body;
wherein the catheter assembly has a first configuration in which the deployment mechanism is in the non-actuated position and the cuff is supported by and movable with the cuff deployment device, and a second configuration in which the deployment mechanism is in the actuated position and the cuff is concentrically mounted at a fixed axial location of the elongate tubular body and is free of contact with the cuff deployment device; and
wherein the cuff deployment device is out of contact with the internal catheter engagement surface in both the actuated position and the non-actuated position.

Abstract
A catheter assembly includes a catheter having an elongate tubular body defining a lumen extending from an open proximal end to an open distal end. A cuff deployment device is concentrically supported on the elongate tubular body and is movable along a longitudinal axis of the elongate tubular body. The cuff deployment device includes a deployment mechanism having an actuated position and a non-actuated position. A cuff has a hollow cylindrical body defining an internal catheter engagement surface. The catheter assembly has a first configuration in which the deployment mechanism is in the non-actuated position and the cuff is supported by and movable with the cuff deployment device, and a second configuration in which the deployment mechanism is in the actuated position and the cuff is concentrically mounted at a fixed axial location of the elongate tubular body and is free of contact with the cuff deployment device.

15. A method of implanting a catheter assembly in a patient vasculature, the catheter assembly including:
- a catheter having an elongate tubular body with an external surface and defining a lumen extending from an open proximal end of the elongate tubular body to an open distal end of the elongate tubular body;
a cuff deployment device concentrically supported on the elongate tubular body and movable along a longitudinal axis of the elongate tubular body, wherein the cuff deployment device includes a deployment mechanism having an actuated position and a non-actuated position; and
a cuff having a hollow cylindrical body defining an internal catheter engagement surface for contacting the external surface of the elongate tubular body;
wherein the catheter assembly has a first configuration in which the deployment mechanism is in the non-actuated position and the cuff is supported by and movable with the cuff deployment device, and a second configuration in which the deployment mechanism is in the actuated position and the cuff is concentrically mounted at a fixed axial location of the elongate tubular body and is free of contact with the cuff deployment device, and wherein the cuff deployment device is out of contact with the internal catheter engagement surface in both the actuated position and the non-actuated position, the method comprising steps of;sliding the cuff deployment device toward the fixed axial location while the catheter assembly is in the first configuration; moving the catheter assembly from the first configuration to the second configuration at least in part by actuating the deployment mechanism; and removing the cuff deployment device from the elongate tubular body of the catheter. - View Dependent Claims (16, 17, 18, 19, 20)
