Abstract: Disclosed embodiments of introducer devices provide hemostatic sealing and allow a delivery catheter to be inserted through the introducer seals without the use of a separate loader device that covers a medical device that is mounted on the catheter. Some disclosed introducers comprise a housing, a distal sheath extending distally from the housing and adapted to be inserted into a patient's vasculature, a distal hemostatic seal mounted within the housing and a proximal hemostatic seal mounted within the housing, and a slidable tube positioned within the housing that is movable longitudinally relative to the distal hemostatic seal between a proximal position and a distal position, wherein in the proximal position a distal end of the tube is positioned proximal to the distal hemostatic seal with the distal hemostatic seal closed, and wherein in the distal position the distal end of the tube extends through the distal hemostatic seal.

Abstract: The present invention is directed to a deployment system for an endoluminal device. The deployment system includes a confining sheath placed around a compacted endoluminal device. A deployment line is provided in the system. As the deployment line is actuated, the sheath retracts from around the compacted endoluminal device. Once the sheath is retracted from around the compacted endoluminal device, the endoluminal device is operable to expand. Any remaining sheath material is removed from the implantation site along with the deployment line.

Abstract: A surgical clip applier comprising an electric motor system is disclosed. The electric motor system is configured to drive one or more drive systems of the surgical clip applier. The surgical clip applier comprises a control system configured to control the electric motor system. The control system is configured to monitor a parameter of the electric motor system to assess the operation of the one or more drive systems. In at least one instance, the control system monitors the electric current drawn by an electric motor and adapts the operation of the electric motor based on the electric current being drawn by the motor. The control system slows the electric motor down when the electric current drawn by the electric motor exceeds a threshold. The control system modulates the width, or duration, of voltage pulses applied to the electric motor to control the speed of the electric motor.

Abstract: Devices can generally include an implant having a braided section that can be implanted in a deployed state such that, in the deployed state, the braided section folds to form an outer occlusive sack extending across a neck of an aneurysm to engage a wall of the aneurysm from within a sac of the aneurysm and an inner occlusive sack forming a trough nested within the outer occlusive sack. The implant can be closed at one or more of the braid ends to define a substantially enclosed bowl-shaped volume.
Abstract: Methods and devices for using surgical devices with articulating end effectors are provided. Surgical devices with articulating end effectors can provide rotary driven pivoting of the end effector. In some embodiments, the device can include a handle, a first and a second tube extending from the handle, the second tube disposed within the first tube, and an end effector that includes a pair of distal jaws configured to move in response to rotation of the first tube about a longitudinal axis thereof and rotation of the second tube about a longitudinal axis thereof. The jaws can move in two different ways depending on whether the first and second tubes are rotating in a same direction as one another or in different ways than each other. The jaws can open/close and articulate using the same mechanical mechanism. The device can be powered, or the device can be non-powered.

Abstract: An apparatus includes a thread (58) and a tissue anchor (60) coupled to the thread. The anchor includes a proximal portion (60p), shaped to define one or more appendages (82), a distal portion (60d), and a plurality of strips (84) joining the proximal portion to the distal portion. The anchor is configured to anchor the thread at tissue (42) of a subject by virtue of the appendages expanding radially, and the strips expanding radially to form respective loops at a distal side of the tissue, upon removal of a radially-constraining force from the anchor. Other embodiments are also described.
