Devices and methods for assisting medical treatments
A treatment device (500) is provided including a shaft (507), an expandable member, a first elongated control member (508) and a second elongated control member (502). The expandable member can further include at least a first controllable portion (504) and a second controllable portion (503), where the expandable member, including the first controllable portion and the second controllable portion, is configured to transition between at least a partially retracted configuration and an expanded configuration under control of at least the first elongated control member (508). Further still, the first controllable portion can be configured to transition between at least a partially retracted configuration and an expanded configuration, while the second controllable portion (503) is configured to remain substantially unchanged, under control of at least the second elongated control member (502).
THIN-FILM MICROMESH FOR MEDICAL DEVICES AND RELATED METHODS
Thin-film mesh for medical devices, including stent and scaffold devices, and related methods are provided. Micropatterned thin-film mesh, such as thin-film Nitinol (TFN) mesh, may be fabricated via sputter deposition on a micropatterned wafer. The thin-film mesh may include slits to be expanded into pores, and the expanded thin-film mesh used as a cover for a stent device. The stent device may include two stent modules that may be implanted at a bifurcated aneurysm such that one module passes through a medial surface of the other module. The thin-film mesh may include pores with complex, fractal, or fractal-like shapes. The thin-film mesh may be used as a scaffold for a scaffold device. The thin-film scaffold may be placed in a solution including structural protein such as fibrin, seeded with cells, and placed in the body to replace or repair tissue.
MEDICAL DEVICE WITH ENHANCED SHAPE CHARACTERISTICS
A medical device is disclosed and may have a spiral shape structure that can function as a stent, such as a flow diversion stent to treat aneurysms. The medical device may have a spiral shape structure that can function as an occlusive device, for instance to occlude aneurysms. The medical device may include a shape setting structure to selectively adjust the shape of the medical device.
Thin film vascular stent and biocompatible surface treatment
A vascular implant, comprising a sheet comprising thin film nickel titanium (NiTi), wherein the sheet has at least one super-hydrophilic surface having a water contact angle of less than approximately 5 degrees. The sheet is configured to have a compacted form having a first internal diameter and a deployed form having a second internal diameter larger than the first internal diameter. The sheet may be delivered into a blood vessel in the compacted form and expanded to its deployed form at a treatment location within the blood vessel, wherein the stent is configured to expand onto an internal surface of the blood vessel and exert a radial force on said internal surface.
SYSTEM FOR AND METHOD OF TREATING ANEURYSMS
An apparatus for treating an aneurysm in a blood vessel includes a wire to be advanced within a tube and an occlusion element disposed on the wire. The occlusion element includes a cover and an inner anchoring member. The occlusion element is configured to fit within the tube and slide out of an opening at distal end of the tube in response to movement of the wire. The cover is configured to expand to an expanded configuration when advanced into the aneurysm, wherein the cover comprises a diameter that is greater than the diameter of a neck portion of the aneurysm and is configured such that a first portion of the cover contacts an interior surface of the aneurysm and a second portion covers the neck portion of the aneurysm. The inner anchoring member extends from the cover portion and is configured to contact the interior surface of the aneurysm.
Aneurysm method and system
The present disclosure relates to a self-expanding braided implant, including a distal implant end and a proximal implant end, the braided implant being invertible about the distal implant end. Translation of the braided implant distally causes the braided implant to invert and fold into itself thereby forming an occlusive sack configured to occlude the aneurysm.
DEVICE USEFUL FOR LOCALIZED THERAPEUTIC DELIVERY WITHOUT FLOW OBSTRUCTION
Medical devices and methods are provided. In some aspects, devices useful for applying therapy locally within a body vessel are disclosed, the devices having a stent graft with flared end regions with a catheter providing fluid communication to the outer side of the narrower, intermediate region of the stent graft. Kits and systems including the same devices and methods are also disclosed.
IMPLANTABLE EMBOLIZATION DEVICE
In some examples, an embolization device includes multiple sections with three-dimensional non-helical structures when deployed at a vascular site. The multiple sections include a first section and one or more second sections that are smaller than the first section. The first section may have a deployed structure configured to anchor the device at a vascular site (e.g., a blood vessel) of a patient while each of the one or more second sections may be formed from loops that configured to pack and obstruct the vascular site. In some cases, the embolization device also includes a third section having a deployed configuration with multiple helical windings or loops is configured to anchor the embolization device at the vascular site.
Methods and apparatus for luminal stenting
Described herein are flexible implantable occluding devices that can, for example, navigate the tortuous vessels of the neurovasculature. The occluding devices can also conform to the shape of the tortuous vessels of the vasculature. In some embodiments, the occluding devices can direct blood flow within a vessel away from an aneurysm or limit blood flow to the aneurysm. Some embodiments describe methods and apparatus for adjusting, along a length of the device, the porosity of the occluding device. In some embodiments, the occluding devices allows adequate blood flow to be provided to adjacent structures such that those structures, whether they are branch vessels or oxygen-demanding tissues, are not deprived of the necessary blood flow.
Stent and Catheter Systems for Treatment of Unstable Plaque and Cerebral Aneurysm
The invention generally relates to co-axial stent and catheter systems and medical procedures utilizing these systems. The co-axial stent system is characterized by two-coaxial stents, including an outer resorbable stent and an inner metal stent used to effect deployment of the resorbable stent. The stents may use for treatment of unstable plaque and/or thrombus at the carotid bifurcation and particularly those that are not causing any significant stenosis. The stents may also be used for treatment of cerebral aneurysms. The invention further describes related, equipment, uses and kits for the treatment of unstable plaque and/or thrombus and/or aneurysms.
