Abstract
A guidewire manipulation device includes a housing configured to be supported by the hand of a user, the housing having a distal end and a proximal end, the housing configured to allow a guidewire to be placed therethrough and extend between the distal end and proximal end, a drive system carried by the housing and configured to drive rotation of the guidewire, and a manual input module carried by the housing, the manual input module configured to allow one or more fingers of the hand of the user to manually stop or slow the rotation of the guidewire while the housing is supported by the hand of the user.
Claims26
A guidewire manipulation device configured for single hand use comprising:
- a housing configured to be supported by a hand of a user, the housing including a distal end, a proximal end, and a longitudinal axis extending therebetween, the housing comprising a passage extending from the distal end of the housing to the proximal end of the housing, the passage configured for a guidewire to be placed therethrough;
- a chuck rotationally coupled to the housing, the chuck having a locked mode configured to engage the guidewire such that rotation of the chuck causes corresponding rotation of the guidewire, while maintaining the longitudinal position of the guidewire in relation to the housing, the chuck further having an unlocked mode wherein the chuck is configured to not cause rotation of the guidewire;
- a motor carried by the housing and configured to drive rotation of the chuck, the motor having a stall torque, the motor configured to be switched between an on condition and an off condition;
- a hand grip extending from the housing in a generally radial direction in relation to the longitudinal axis;
- and
- an engagement interface carried on an external portion of the chuck such that the engagement interface maintains a particular longitudinal position in relation to the hand grip when the chuck is in the locked mode, wherein the engagement interface, the hand grip, and the stall torque are configured to collectively allow one or more fingers of the hand of the user to apply a force to the engagement interface sufficient to stop or slow the rotation of the chuck while the hand grip is being gripped by the hand of the user and while the motor is in the on condition and rotationally driving the chuck.

A method for manipulating an elongate medical device, comprising:
- providing a guidewire manipulation device configured for single hand use comprising:
- a housing configured to be supported by a hand of a user, the housing including a distal end, a proximal end, and a longitudinal axis extending therebetween, the housing comprising a passage extending from the distal end of the housing to the proximal end of the housing, the passage configured for a guidewire to be placed therethrough;
- a chuck rotationally coupled to the housing, the chuck having a locked mode configured to engage the guidewire such that rotation of the chuck causes corresponding rotation of the guidewire, while maintaining the longitudinal position of the guidewire in relation to the housing, the chuck further having an unlocked mode wherein the chuck is configured to not cause rotation of the guidewire;
- a motor carried by the housing and configured to drive rotation of the chuck, the motor having a stall torque, the motor configured to be switched between an on condition and an off condition;
- a hand grip extending from the housing in a generally radial direction in relation to the longitudinal axis;
- and
- an engagement interface carried on an external portion of the chuck such that the engagement interface maintains a particular longitudinal position in relation to the hand grip when the chuck is in the locked mode, wherein the engagement interface, the hand grip, and the stall torque are configured to collectively allow one or more fingers of the hand of the user to apply a force to the engagement interface sufficient to stop or slow the rotation of the chuck while the hand grip is being gripped by the hand of the user and while the motor is in the on condition and rotationally driving the chuck;
- securing an elongate medical device to the chuck;
- grasping the guidewire manipulation device in a first hand;
- and
- causing the elongate medical device to change a rotation speed by input to the engagement interface from one or more fingers of the first hand.
