Abstract
A closure device includes an actuator movable between an initial extended position, a first position, and a second position with respect to a housing of the closure device, an inner seal configured to deploy from a distal end of the closure device when the actuator shifts from the initial extended position to the first position, a biasing mechanism configured to urge the actuator from the first position to the second position when a first pulling force is applied to the housing, and a locking member configured to deploy from the distal end of the closure device when the actuator shifts from the second position to the first position subsequent to deployment of the inner seal.
Claims15
A method for sealing a percutaneous puncture in the wall of a blood vessel, comprising:
- providing an insertion tool having an actuator which is operable in a first mode in which the actuator is configured for deployment of an inner seal inside the vessel and operable in a second mode in which the actuator is configured for tamping a locking member on an outside of the vessel, wherein the actuator is arranged to be set into said second mode in response to a pulling force acting on a filament connecting the inner seal and the locking member;
- operating said insertion tool in said first mode by depressing the actuator towards a closure device housing;
- pulling said filament so as to set said actuator in said second mode;
- and
- operating said insertion tool in said second mode by depressing the actuator towards the closure device housing.
A closure device, comprising:
- an actuator movable between an initial extended position, a first position, and a second position with respect to a housing of the closure device;
- an inner seal configured to deploy from a distal end of the closure device when the actuator shifts from the initial extended position to the first position;
- a biasing mechanism configured to urge the actuator from the first position to the second position when a pulling force is applied to the housing;
- and
- a locking member configured to move into a locking position;
- wherein the actuator is configured such that movement of the actuator from the second position towards the housing of the closure device causes a substantially simultaneous movement of the locking member into the locking position.
A closure device for sealing a blood vessel, comprising:
- an inner seal configured to deploy from the closure device into the blood vessel;
- a locking member configured to deploy from the closure device to abut an outer surface of the blood vessel;
- a filament to connect the inner seal and the locking member;
- a latch mechanism configured to maintain an actuator stationary in a first position relative to a housing of the closure device without force from a user;
- wherein the closure device is configured such that application of a pulling force to the filament, subsequent to deployment of the inner seal, releases the latch mechanism to shift the actuator of the closure device from the first position to a second position relative to the housing of the closure device and to enable deployment of the locking member.
A closure device, comprising:
- an actuator movable between an initial extended position, a first position, and a second position with respect to a housing of the closure device;
- an inner member configured to deploy from a distal end of the closure device when the actuator shifts from the initial extended position to the first position;
- a biasing mechanism configured to urge the actuator from the first position to the second position when a pulling force is applied to the housing;
- and
- a second member configured to deploy from the distal end of the closure device;
- wherein the actuator is configured such that movement of the actuator from the second position towards the housing of the closure device causes a substantially simultaneous deployment of the second member from the distal end of the closure device.
