Abstract: A device for treating vascular malformations includes a primary coil and secondary windings. The primary coil provides resilience and structural integrity while the secondary windings fill interstitial spaces in the primary coil to isolate the vascular malformation. The device may have increased density along a central portion to isolate the malformation. In another aspect, the device may have a central opening through which embolic materials may be delivered.

Abstract: A system for removing an obstruction from a blood vessel includes an obstruction engaging element and an expandable capture element. The capture element preferably has a flexible cover and an expandable support structure. The engaging element engages the obstruction and moves the obstruction into the capture element. The capture element protects the obstruction when the obstruction is moved into the catheter.

Abstract: The invention is also directed to a device for treating an aneurysm which has a cover covering the neck of the aneurysm and a lateral portion extending into the aneurysm. The invention is also directed to a cover which is used to cover the neck of the aneurysm thereby isolating the aneurysm from the parental vessel.

Abstract: Devices and methods for removing an obstruction from a blood vessel are described. The devices are deployed in a collapsed condition and are then expanded within the body. The devices are then manipulated to engage and remove the obstruction.

Abstract: A system for delivering multiple implants into lung passageways is disclosed. The system comprises a catheter configured to receive and store a plurality of expandable implants, and an actuatable delivery tool coupled to the proximal end of the catheter. The system expels an implant of the plurality of implants with each actuation of the delivery tool. The delivery tool comprises a plunger element which extends through the catheter from the proximal to the distal end and allows the delivery tool to mechanically communicate with the implants. In one embodiment, the system comprises a spring-loaded slidable element, and a user compresses the slidable element to actuate the delivery tool. In another embodiment, the system comprises a rotation rod, and the user moves the rotation rod in a distal direction to actuate the delivery tool.

Abstract: A removal tool for an implanted device, including pulmonary stents, occlusive devices, valved devices, and flow-restrictive devices, is provided. The removal tool includes an elongate tube having a central passage, a slideable inner member within the passage, and a coupling member disposed on the distal end of the inner member. The coupling member of the removal tool includes a distal tip configured to pierce a membrane of the implanted device. The coupling member also includes a coil or a hook configured to engage a support element of the implanted device. A method of removing implanted devices is also provided. A removal tool is placed adjacent to the device, the distal end of the tool is moved to pierce its membrane, a portion of the tool engages the support member, and the distal end of the tool is retracted along with the implanted device.

Abstract: Devices for loading a collapsible implant onto a delivery catheter. In one aspect, a loading device comprises an outer tubular structure and an inner tubular structure. The outer tubular structure comprises a narrowing passage configured to receive a catheter at one end and a collapsible implant at another end. The inner tubular structure is configured to move slidably and co-axially within the outer tubular structure. The inner tubular structure comprises a carrier pin configured to move within the narrowing passage as the inner tubular structure slides into the outer tubular structure. The sliding of the inner tubular structure into the outer tubular structure causes an implant mounted on the carrier pin to collapse as the implant moves through the narrowing passage and into the distal end of a catheter.

Abstract: Lung conditions are diagnosed and optionally treated using a functional assessment catheter or a functional lung assessment and treatment catheter. A flow restrictive component is initially placed in a bronchus or lung passageway upstream from a diseased lung region. The isolated lung region is then functionally assessed through the catheter, while the flow restrictive component remains in place. If the patient is a good candidate for treatment by occlusive or restrictive treatment techniques, the flow resistive component may be left in place. If the patient is not suitable for such treatment, the flow resistive component may be removed.
