Abstract

The invention is directed to a delivery system for delivering a medical device. The delivery system includes an inner member having a proximal end and a distal end. The inner member defines a longitudinal axis between the proximal end and the distal end. A tip is formed at the distal end of the inner member. A bumper is freely disposed on the inner member. The bumper has a proximal end and a distal end. A seat is defined between the tip and the distal end of the bumper. Additionally, a sheath is disposed about the inner member, the sheath having a proximal end and a distal end. The sheath is movable from a first sheath position substantially covering the seat, and a second sheath position axially offset to expose the seat. The invention also includes a handle in contact with the proximal end of the inner member.

Claims

1. A delivery system for delivery of a medical device, the delivery system comprising:

an inner member having a proximal end and a distal end, the inner member defining a longitudinal axis therebetween;

a sheath disposed about the inner member, the sheath having a proximal end and a distal end, the sheath being movable from a first sheath position to a second sheath position;

a handle coupled with the proximal end of the inner member;

an actuator on the handle and coupled with the sheath for linear movement thereof along the longitudinal axis; and

a lock on the handle, the lock having a locked position prohibiting movement of at least one of the actuator and sheath, and an unlocked position permitting movement of the at least one of the actuator and sheath, and wherein the lock is operatively disposed to move the sheath an initial distance when the lock is moved from the locked position to the unlocked position.

2. The delivery system of claim 1, wherein the lock includes a locking lever.

3. The delivery system of claim 1, wherein the lock is operationally engaged to the actuator and configured to releasably lock the at least one of the actuator and sheath when in the locked position.

4. The delivery system of claim 1, wherein the lock includes a cam to cooperate with the actuator to provide the initial movement of the sheath.

5. The delivery system of claim 2, wherein the locking lever is hingedly attached to the handle.

6. The delivery system of claim 3, wherein the locking lever includes a detent configured to engage the actuator to inhibit movement of the sheath.

7. A delivery system for delivery of a medical device, the delivery system comprising:

an inner member having a proximal end and a distal end, the inner member defining a longitudinal axis therebetween;

a tip disposed at the distal end of the inner member;

a bumper disposed on the inner member, the bumper having a proximal end and a distal end, the bumper including a sleeve member having a length and a tubular wall, a seat being defined between the tip and the distal end of the bumper;

a sheath disposed about the inner member, the sheath having a proximal end and a distal end, the sheath being movable from a first sheath position substantially covering the seat, and a second sheath position axially offset to expose the seat;

a handle in contact with the proximal end of the inner member;

an actuator on the handle and coupled with the sheath for linear movement thereof along the longitudinal axis; and

a lock on the handle, the lock having a locked position prohibiting movement of at least one of the actuator and sheath, and an unlocked position permitting movement of the at least one of the actuator and sheath, and wherein the lock is operatively disposed to cause initial movement of the sheath when the lock is moved from the locked position to the unlocked position.

8. The delivery system of claim 7, wherein the lock includes a locking lever.

9. The delivery system of claim 7, wherein the lock is operationally engaged to the actuator and configured to releasably lock the at least one of the actuator and sheath, when in the locked position.

10. The delivery system of claim 7, wherein the lock includes a cam to cooperate with the actuator to provide the initial movement of the sheath.

11. The delivery system of claim 8, wherein the locking lever is hingedly attached to the handle.

12. The delivery system of claim 9, wherein the locking lever includes a detent configured to engage the actuator to inhibit movement of the sheath.
