  • Publication number: 20200107776
    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.

  • Patent number: 8597320
    Abstract: A method of filling an aneurysm is described which includes the step of advancing a device through a patient's vascular system to an aneurysm and positioning the device within the aneurysm. The device has a closed mesh structure forming by a plurality of flexible filaments. The device also has a proximal collar and a distal collar with the flexible filaments extending therebetween. The closed mesh structure is movable from a collapsed configuration to an expanded configuration.

  • Patent number: 8100959
    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.

  • Publication number: 20110251509
    Abstract: Devices systems and methods are disclosed for preventing or inhibiting secretions from entering the lumen of a functional assessment catheter for the lungs, or removing collected secretions. The catheter comprises an expandable element, a cover, or an internal component configured to prevent or inhibit secretion flow into the lumen. The catheter alternatively or additionally comprises a distal end configured to facilitate air flow, absorb secretions or repel secretions away from the catheter tip. The catheter alternatively or additionally comprises an internal element such as a coilable wire, or an obturator configured to prevent secretions from being drawn into the lumen, or to actively remove the secretions. The catheter alternatively or additionally comprises an element to dry, aerate or aspirate the lung passageways.

  • Publication number: 20110224776
    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.
