1. A catheter system for positioning an instrument within a body, the catheter system comprising:
- a hub defining a lumen therethrough for passage of the instrument toward the body;
an elongate tubular member defining a lumen therethrough, the lumen of the elongate tubular member being in communication with the lumen of the hub for further passage of the instrument toward the body;
a slitter member that is coupled to the hub, the slitter member disposed to slit the elongate tubular member as the elongate tubular member moves relative to the hub; and
a moveable member removably coupled to the hub and coupled to the elongate tubular member, wherein the moveable member is movable to advance the elongate tubular member toward the slitter member as the moveable member is moved relative to the hub such that the slitter member slits the elongate tubular member, and further wherein at least the movable member maintains the elongate tubular member in a fixed position relative to the hub prior to moving the movable member relative to the hub to advance the elongate tubular member.

Abstract
A catheter system for positioning an instrument within a body that includes a hub defining a lumen therethrough for passage of the instrument toward the body. The catheter system also includes an elongate tubular member defining a lumen therethrough. The lumen of the elongate tubular member is in communication with the lumen of the hub for further passage of the instrument toward the body. The system also includes a slitter member that is coupled to the hub. The slitter member is disposed to slit the elongate tubular member as the elongate tubular member moves relative to the hub.

17. A catheter system for positioning an instrument in a body, wherein the system comprises:
-
an elongate tubular member extending from a proximal end to a distal end and defining a lumen therethrough; a hub comprising a proximal end and a distal end, wherein the hub defines a sealed passageway extending from the proximal end to the distal end along a longitudinal axis for passage of the instrument; a slitter member coupled to the hub configured to slit the elongate tubular member; and a movable member removably coupled to the hub and coupled to the elongate tubular member, wherein at least the movable member maintains the elongate tubular member in a fixed position relative to the hub prior to moving the movable member relative to the hub to advance the elongate tubular member such that the lumen of the elongate tubular member is aligned with the sealed passageway of the hub along the longitudinal axis for passage of the instrument from the sealed passageway to the lumen of the elongate tubular member when the instrument is being positioned in the body, and further wherein the elongate tubular member is removable from the hub by moving the movable member relative to the hub to advance the elongate tubular member to be sated toward the slitter member. - View Dependent Claims (18, 19, 20, 21, 22, 23)

24. A catheter system for positioning an instrument in a body, wherein the system comprises:
-
an elongate tubular member extending from a proximal end to a distal end and defining a lumen therethrough; a hub comprising a proximal end and a distal end, wherein the hub defines a passageway extending from the proximal end to the distal end along a longitudinal axis, and further wherein the hub further comprises a guide loop; a slitter member coupled to the hub configured to slit the elongate tubular member; and a movable member removably coupled to the hub and coupled to the elongate tubular member, wherein at least the movable member maintains the elongate tubular member in a fixed position relative to the hub prior to moving the movable member relative to the hub to advance the elongate tubular member such that the lumen of the elongate tubular member is aligned with the passageway of the hub along the longitudinal axis, wherein the elongate tubular member is removable from the hub by moving the movable member relative to the hub to advance the elongate tubular member to be sated toward the slitter member, and further wherein the guide loop guides the elongate tubular member generally along the longitudinal axis when the elongate tubular member is being removed from the hub. - View Dependent Claims (25)
