A surgical clamp assemblyfor use in keyhole surgery is disclosed. The assembly includes: a surgical clampfor forming a clamping loop around a bodily lumen. The clamp includes: a strap, the strap including an elongate grippable portion; and a headincluding a gripper, the gripper having an open mouth, the open mouth shaped to allow lateral entry of the strap into the gripper so as to form the clamping loop. The assembly further includes: a deployment tubefor deploying the clamp through a keyhole; and a manipulatorfor manipulating the clamp through the deployment tube. The elongate body is biased to move from a constrained generally straight condition within the deployment tube to an unrestrained curled condition within a patient. A surgical clamp assembly, that includes a surgical clamp is also disclosed.

Surgical clamp apparatus and a surgical clamp for use in keyhole surgery

An endovascular introducer which has a handle assembly, a stent graft deployment device and a stent graft retained on the stent graft deployment device. The handle assembly has a first part and a second part, the second part to be moved relative to the first part. The first part has a fixed portion to be gripped and held by a user and a rotating portion to be rotated. A one way clutch arrangement transfer rotation to co-acting first screw threads so that relative longitudinal motion between the first part and the second part occurs. The deployment device has a pusher assembly and a sheath to cover the stent graft on the pusher assembly. The sheath is connected to the second part so that rotation of the rotating portion causes retraction of the sheath.

Rotation operated delivery device

A stent graft introducer has stent graft releasably retained onto a deployment catheter and a sheath encloses the stent graft. A handle assembly has a handle, a first slide and a second slide. The first slide retracts within the second slide and the second slide retracts within the handle. An actuation arrangement comprises a first longitudinal gear rack on the first slide, a second longitudinal gear rack on the second slide and a ratchet lever assembly on the handle. Actuation of the ratchet lever assembly causes the second slide to fully retract into the handle at which time the ratchet lever assembly engages the first gear rack through an aperture in the second rack and continued actuation causes retraction of the first slide thereby retracting the sheath from the pusher to expose the stent graft.
