Multipurpose handle
A multipurpose handle incorporated into a medical device delivery system. The multipurpose handle includes an elongate handle body, an actuation button, and a locking member. The elongate handle body has a proximal end extending to a distal end, which defines a longitudinal axis. The elongate body further includes a cutout that creates a movement space therein in which the actuation button is disposed and is connected to a medical device. The actuation button is movable within the cutout along the longitudinal axis and rotatable within the cutout. The locking member is connected to the elongate handle body and movable between a locked position and unlocked position. The locking member may be in contact with the actuation button and be configured to restrict the movement of the actuation button along the longitudinal axis when in the locked position.
1. A multipurpose handle for delivery or retrieval of a medical device, the multipurpose handle comprising:
an elongate handle body having a proximal end extending to a distal end defining a longitudinal axis, the elongate handle body having a cutout defining a movement space therein, the cutout including a longitudinal slot on an upper side of the elongate handle body opening to a cavity in the elongate handle body;
a thumb wheel having a proximal face and a distal face, the thumb wheel disposed within the cutout of the elongate handle body with a portion received in the cavity and a portion exposed at the longitudinal slot for operation by a thumb of a hand of a user in a grip position gripping the elongate handle body, the thumb wheel connected to the medical device, the thumb wheel being movable within the cutout along the longitudinal axis and rotatable within the cutout;
a locking member connected to the elongate handle body and movable between a locked position and an unlocked position, the locking member being positioned on a lower side of the elongate handle body opposite the upper side and accessible to and operable by an index finger of the hand of the user in the grip position, wherein upwardly pivoting movement of the locking member from the unlocked position to the locked position moves the locking member into the cavity and into direct abutting contact with the distal face of the thumb wheel and restricts movement of the thumb wheel along the longitudinal axis; and
wherein the thumb wheel is connected to the medical device such that longitudinal movement of the thumb wheel within the cutout along the longitudinal axis moves the medical device longitudinally and rotation of the thumb wheel within the cutout rotates the medical device.
2. The multipurpose handle of claim 1 , wherein the locking member is configured to have an unlocked state in which the locking member remains in the unlocked position until forced by a user to the locked position, and wherein the thumb wheel is movable slidably within the cutout along the longitudinal axis while the locking member remains in the unlocked state.
3. The multipurpose handle of claim 1 , wherein the thumb wheel includes fins disposed on the circumference of the thumb wheel.
4. The multipurpose handle of claim 1 , wherein the thumb wheel includes a tactile bump.
5. The multipurpose handle of claim 1 , wherein the cutout is droplet shaped.
6. The multipurpose handle of claim 1 , wherein the longitudinal axis of the elongate handle body and a longitudinal axis of the locking member are located such that the locking member rotates into the elongate handle body.
7. The multipurpose handle of claim 1 , wherein the locking member includes a spring configured to hold the locking member in the locked position or unlocked position.
8. The multipurpose handle of claim 7 , wherein the spring exhibits a force to hold the locking member in the locked position or the unlocked position, such that an external force applied to the locking member that overcomes the force of the spring is able to cause the locking member to move from the unlocked position to the locked position or from the locked position to the unlocked position.
9. The multipurpose handle of claim 1 , wherein the thumb wheel further comprises one or more protrusions configured to prevent the thumb wheel from being removed from the elongate handle body.
10. A medical device delivery system comprising:
an outer sheath;
a medical device located at least partially within the outer sheath in an initial configuration ready for deployment; and
a multipurpose handle connected to the outer sheath and the medical device, the handle comprising:
an elongate handle body having a proximal end extending to a distal end defining a longitudinal axis, the elongate handle body having a cutout defining a movement space therein, the cutout including a longitudinal slot on the elongate handle body opening to a cavity in the elongate handle body;
a thumb wheel disposed within the cutout of the elongate handle body with a portion received in the cavity and a portion exposed at the longitudinal slot for operation by a thumb of a hand of a user in a grip position gripping the elongate handle body, the thumb wheel connected to the medical device, the thumb wheel being movable slidably within the cutout along the longitudinal axis to move the medical device longitudinally and rotatable within the cutout to rotate the medical device;
a locking member connected to the elongate handle body and movable between a locked position and an unlocked position, the locking member being accessible to and operable by an index finger of the hand of the user in the grip position, wherein upwardly pivoting movement of the locking member from the unlocked position to the locked position moves the locking member into the cavity and into direct abutting contact with a distal face of the thumb wheel and restricts movement of the thumb wheel along the longitudinal axis.
11. The medical device delivery system of claim 10 , wherein the medical device is a stent, an embolic coil, or a vena cava filter.
12. The medical device delivery system of claim 10 , wherein the locking member is configured to have an unlocked state in which the locking member remains in the unlocked position until forced by a user to the locked position, and wherein the thumb wheel is movable slidably within the cutout along the longitudinal axis while the locking member remains in the unlocked state.
13. The medical device delivery system of claim 10 , configured for delivering or retrieving the medical device from a targeted site in a vasculature of a patient.
14. A multipurpose handle for delivery or retrieval of a medical device, the multipurpose handle comprising:
an elongate handle body having a proximal end extending to a distal end defining a longitudinal axis, the elongate handle body having a cutout defining a movement space therein;
a thumb wheel having a proximal face and a distal face, the thumb wheel disposed within the cutout of the elongate handle body and connected to the medical device, the thumb wheel being movable within the cutout along the longitudinal axis and rotatable within the cutout;
a locking member connected to the elongate handle body and movable between a locked position and unlocked position, the locking member being in contact with the thumb wheel and restricting movement of the thumb wheel along the longitudinal axis in the locked position; and
wherein the cutout is droplet shaped.
15. The multipurpose handle of claim 14 , wherein in the locking position, the locking member is in contact with the distal face of the thumb wheel.
16. The multipurpose handle of claim 14 , wherein the locking member includes a locking ring.
17. The multipurpose handle of claim 14 , wherein the locking member includes a locking button configured to slide or be pushed in order to provide the locked position.
