ANEURYSM TREATMENT WITH PUSHABLE BALL SEGMENT
The present invention provides a braided implant with a retractable dual proximal layer and methods for administering the braided implant to treat aneurysms. The implant can include a tubular braid that can be set into a predetermined shape, compressed for delivery through a microcatheter, and implanted in at least one implanted position that is based on the predetermined shape and the geometry of the aneurysm in which the braid is implanted. The implant can also have a retractable ball segment at the proximal end of the device made of the same braid that can be heat treated into an ellipsoid shape. The retractable ball segment can be movable from a position outside the aneurysm to a position at least partially enclosed within the implant to increase or decrease the height of the implant relative to the aneurysm or better conform the implant to the neck of the aneurysm.
COMBINATORIAL THERAPIES INCLUDING IMPLANTABLE DAMPING DEVICES AND BIOLOGIC THERAPEUTIC AGENTS FOR TREATING A CONDITION AND ASSOCIATED SYSTEMS AND METHODS OF USE
Devices, systems, and methods for combinatorial treatment of a condition with an implantable damping device and biologic therapeutic agent are disclosed herein. Methods for treating one or more effects of the condition, such as a neurological condition, include providing the implantable damping device and at least one other therapy, such as a biologic therapeutic agent, that treats the condition to the patient. The implantable damping device includes a flexible damping member and an abating substance and can be placed in apposition with a blood vessel. The flexible damping member forms a generally tubular structure having an inner and an outer surface, the inner surface formed of a sidewall having a partially deformable portion. The abating substance is disposed within the partially deformable portion and moves longitudinally and/or radially within the partially deformable portion in response to pulsatile blood flow.
LOW RADIAL FORCE VASCULAR DEVICE AND METHOD OF OCCLUSION
An occlusion apparatus comprises inner and outer sheaths and an expandable flexible tubular sleeve. The occlusion apparatus is advanced to a target site in the blood vessel. A dilator having a soft, compressible tip may be advanced through a lumen of the inner sheath to facilitate the advancement of the occlusion apparatus. The sheaths are translated relative to one another to expand the flexible tubular sleeve to a funnel shape with a distal flush portion contacting the blood vessel inner wall and a proximal tapered portion. The proximal portion is fluid permeable so that blood can pass through to apply pressure on the vessel wall through the distal portion. A capture or traction device can be advanced out of the inner sheath lumen and retracted back therein to capture thrombus. The distal portion of the device may comprise an expandable mesh braid with a memory characteristic to limit expansion.
ANEURYSM OCCLUDING DEVICE FOR USE WITH COAGULATING AGENTS
Devices can generally include a fan portion for occluding an aneurysm neck, a channel orifice opening in the fan portion, and an agent channel for delivering a coagulating agent through the orifice into the aneurysm. Devices can be delivered through a catheter to the aneurysm, the fan portion can expand to occlude the aneurysm neck, and coagulating agent can be injected into the aneurysm. During injection of the coagulating agent, the fan portion can inhibit the coagulating agent from exiting the aneurysm. After injection of the coagulation agent, the fan portion can collapse and the device can be extracted from the patient.
DEFLECTABLE SHEATH FOR LEFT ATRIAL APPENDAGE DEVICE, SYSTEM, AND METHOD THEREOF
Medical devices, systems and methods for occluding a left atrial appendage of a heart with an implant are provided. In one embodiment, a medical device system includes a sheath for delivering the implant. The sheath includes, at a distal portion of the sheath, first and second deflectable portions that are each independently deflectable relative to first and second pivot locations, respectively. With this arrangement, at least one of the first and second pivot locations are adjustable along a longitudinal length of the distal portion of the sheath.
TEMPORARY OCCLUSION OF BLOOD VESSEL USING EXTRA-LUMINAL BALLOON
A method of treating a vessel, such as sclerotherapy, includes moving a short balloon catheter to a position at which a compliant extra-luminal balloon is outside of the vessel at an occlusion site, and between the vessel and a non-compliant bearing surface. The vessel is occluded at the occlusion site by inflating the compliant extra-luminal balloon of the balloon catheter, and bearing an outer surface of the balloon against the vessel and the non-compliant bearing surface. The vessel is medically treated upstream from the occlusion site. The short balloon catheter includes a wire guide lumen
FILTER AND OCCLUDER SYSTEMS AND ASSOCIATED METHODS AND DEVICES
Various aspects of the instant disclosure relate to flow devices including filters and occluders for modifying flow in body conduits such as blood vessels. In some examples, such devices include a support structure and a flow media coupled to the support structure. The medical device generally further includes one or more capture features. In some examples, the capture features are coupled to the support structure at one or more of the proximal and distal ends of the support structure. In various examples, the capture features facilitate retrograde and antegrade deployment of the medical device and retrograde and antegrade capture of the medical device.
Percutaneous catheter directed intravascular occlusion devices with retractable stabilizing wires
A medical device is provided in which one or both ends of the device encourage the formation of tissue across substantially the entire area of the respective end that is exposed to the blood flow for reducing the risk of a thrombotic embolism. The medical device further includes stabilizing wires configured to engage tissue at a target site when the medical device is in an expanded configuration and to at least partially retract into the medical device when the medical device is in a collapsed configuration.
MEDICAL DEVICE DELIVERY MEMBER WITH FLEXIBLE STRETCH RESISTANT MECHANICAL RELEASE
A delivery system for delivering and deploying an implantable medical device is presented that includes a delivery member having a flexible distal portion. The deliver member can include a proximal hypotube, a flexible coil extending distally from the proximal hypotube, a compressible distal hypotube extending distally from the flexible coil, a sleeve extending along the flexible coil, and a loop wire. The loop wire can be effective to inhibit longitudinal elongation of the flexible coil. The sleeve can be effective to inhibit radial expansion of the flexible coil.
Brain aneurysm tool with a wire deflection mechanism
A medical device for treating an aneurysm in a blood vessel includes a hollow shaft for insertion into the blood vessel, an exit port at a distal end of the shaft, a deflection element, and a position sensor. The hollow shaft encompasses a wire-insertion channel for leading a wire to be inserted into the aneurysm. The exit port is configured for exiting the wire from the wire-insertion channel and into the aneurysm. The deflection element is located adjacent to the exit port and configured to deflect the wire from the wire-insertion channel to the exit port. The position sensor, which is coupled to the distal end of the shaft, is configured to produce signals indicative of a position and orientation of the exit port in the blood vessel.
