Catheter sheath devices and methods of operating catheter sheath device

A catheter sheath device comprising:

• an elongate member, at least a portion thereof configured to be insertable into a body of a patient, the elongate member comprising a proximal end portion, a distal end portion, and a first lumen extending between the proximal end portion of the elongate member and the distal end portion of the elongate member, the first lumen sized to allow delivery of at least a distal end portion of a catheter therethrough;
• and
• a moveable member physically coupled to the proximal end portion of the elongate member to permit relative movement therebetween, the moveable member comprising a second lumen extending through the moveable member, the second lumen sized to allow delivery of the at least the distal end portion of the catheter therethrough,
• wherein the moveable member is physically coupled to the proximal end portion of the elongate member to cause, via a first relative movement between the moveable member and the proximal end portion of the elongate member, the second lumen to be positioned at a first location relative to the proximal end portion of the elongate member that permits delivery of the at least the distal end portion of the catheter into the second lumen but not into the first lumen from the second lumen,
• wherein the moveable member is physically coupled to the proximal end portion of the elongate member to cause, via a second relative movement between the moveable member and the proximal end portion of the elongate member, the second lumen to be positioned at a second location relative to the proximal end portion of the elongate member that permits delivery of the at least the distal end portion of the catheter through both the second lumen and the first lumen.
