Steerable medical device
First Claim
1. A method for adjusting a length of a shaft of a medical device, the method comprising:
- manipulating a proximal assembly of the medical device, the proximal assembly being coupled to a proximal end of the shaft, wherein manipulating the proximal assembly includes;
moving a first member of the proximal assembly relative to a second member of the proximal assembly, the first member being coupled to the proximal end of the shaft, to adjust a distance between a distal end of the shaft and a distal end of the second member, andfixing the first member relative to the second member to set the distance between the distal end of the shaft and the distal end of the second member.

Abstract
A steerable medical device is used to controllably introduce a guidewire or other medical instrument into a body of a patient and direct placement of the guidewire or other medical instrument in the body of the patient. The steerable medical device can include an elongated member, a steering mechanism, and an attachment member. The elongated member extends along a longitudinal axis and comprises a deflectable distal portion that is deflectable off of the longitudinal axis. The steering mechanism is adapted to control longitudinal and rotational movement of the elongated member and to control off-axis deflection of its deflectable portion. The attachment member is removably couplable to another medical device. The attachment member is moveably coupled to the steering mechanism and the elongated member.

7. A method for adjusting a position of a first medical device relative to a second medical device, the method comprising:
-
moving an attachment assembly from an engaged configuration, fixedly securing the first medical device to the second medical device, to a disengaged configuration, allowing relative movement between the first and second medical devices; sliding one of a shaft of the first medical device and a shaft of the second medical device relative to the other to adjust a distance between distal ends of the shafts, wherein one of the shafts is received within the other; and moving the attachment assembly to the engaged configuration to fixedly secure the first and second medical devices and set the distance between the distal ends of the shafts. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14)

15. A method for performing a medical procedure with a first medical device and a second medical device, the method comprising:
-
moving a fastener of the first medical device from an engaged configuration, wherein the fastener fixedly secures the first medical device to an attachment member coupling the first medical device to the second medical device, to a disengaged configuration, wherein the fastener allows relative movement between the first medical device and the attachment member; sliding the first medical device relative to the attachment member to extend a distal end of a shaft of the first medical device distally beyond a distal end of a shaft of the second medical device; and moving the fastener to the engaged configuration to fixedly secure the first medical device to the attachment member, with the distal end of the shaft of the first medical device extended distally beyond the distal end of the shaft of the second medical device. - View Dependent Claims (16, 17, 18, 19, 20)
