A coil wire and method of using the coil wire to navigate blood vessels are provided. The coil wire is configured to facilitate coaxial catheter advancement over at least a part of the length of the coil wire. Existing catheters utilize the distal tip of a guidewire to select the vessel origins by shaping it (either during fabrication or by the operating physician) in such a way that the tip will point into the desired vessel as the wire is advanced. The coil wire of the present disclosure functions in a unique manner: its distal tip resumes a pre-formed three-dimensional coil configuration as it is expressed from the catheter. This shape catches the flow of moving blood and propels the coil wire forward while unfurling the coil. As the coil wire is advanced, the small outer diameter of the unfurled coil allows it to pass deep into the selected vessel.

The disclosure relates to a medical kit for the treatment of vascular malformations, in particular aneurysms and/or fistulas, having a permanently implantable covering device, in particular a stent, for covering the vascular malformation, the covering device having a tubular, self-expandable lattice structure and a covering made of an electrospun fabric, the covering being connected to the lattice structure and overlapping the lattice structure at least in part such that, when implanted, the covering is placed over the vascular malformation; and an embolisation means, which can be applied by a feed means in the implanted state for treatment of the vascular malformation, the covering forming a porous membrane which can be penetrated by the feed means for application of the embolisation means and which is designed to lie against the outer periphery of the feed means in the penetrated state.

An implant (1) for the treatment of arteriovenous deformities, in particular aneurysms (2). In an expanded state the implant has a basic body (6) comprising of a proximal and a distal segment (7, 8), with the proximal and the distal segment (7, 8) being of dome-shaped configuration, with the convex side of the dome of the proximal segment (7) facing in the proximal direction and the convex side of the dome of the distal segment (8) facing in the distal direction, and wherein the proximal and the distal segment (7, 8) are connected to each other via a plurality of connecting struts (9). Alternatively, the implant (1) may have the shape of a closed tulip blossom. The inventive implant (1) is able to adapt well to the shape of the respective aneurysm (2).

An occluder (100) and system. The occluder (100) includes a body (110) including a shaping wire (111) and a spring coil (112), the shaping wire (111) formed by a resilient metal wire and configured to have a predetermined shape, the spring coil (112) sleeved on the shaping wire (111) in order to shape the body (110) with the predetermined shape. Through maintaining the shape of the body (110) by means of the shaping wire (111), the body (110) is able to effectively block the breach (30) in aortic dissection treatments.

What is disclosed are medical devices comprising a rounded, thin-walled, expandable metal structure (“ballstent”) and a flexible, elongated delivery device (“delivery catheter”) and systems and methods of use for treating saccular vascular aneurysms with the medical devices. Ballstents comprised of gold, platinum, or silver that can be compressed, positioned in the lumen of an aneurysm, and expanded to conform to the shape of the aneurysm are disclosed. The external surface of ballstents can be configured to promote local thrombosis and to promote the growth of tissue into and around the wall of the ballstent in order to seal the aneurysm and fix the ballstent in place in the aneurysm. The wall of the ballstent can also be configured to release drugs or pharmacologically active molecules, such as those that promote thrombosis, cell proliferation, extracellular matrix deposition, and tissue growth.

Several embodiments are set forth of devices, systems and methods for modifying an atrial appendage such as a left atrial appendage (LAA). In one embodiment, a medical device includes a frame member and a tissue growth member. The frame member includes a unitary, seamless central portion having a plurality of struts defining a multi-cellular structure and an anchoring system, the plurality of struts extending between and configured to self-expand and directly bias the anchor system to anchor the frame member at least partially within the LAA. With this arrangement, the tissue growth member is attached to the frame member to occlude the LAA.

The present invention relates generally to systems and methods for delivering embolic devices into a body lumen of a patient. These embolic devices are applicable to a variety of neurological and/or peripheral applications. In particular, the embolic devices may be used to occlude a vessel within a patient, and/or to treat aneurysms, arteriovenous malformations, traumatic fistulas, uterine fibroids or cancer.

Devices, systems, and methods for reducing stress on a blood vessel are disclosed herein. A damping device configured in accordance with embodiments of the present technology can include an anchoring member coupled to a flexible, compliant damping member including a generally tubular sidewall having an outer surface, an inner surface defining a lumen configured to direct blood flow, a first end portion and a second end portion, and a damping region between the first and second end portions. The inner and outer surfaces of the damping member can be spaced apart by a distance that is greater at the damping region than at either of the first or second end portions. When blood flows through the damping member during systole, the damping member absorbs a portion of the pulsatile energy of the blood, thereby reducing a magnitude of the pulse pressure transmitted to a portion of the blood vessel distal to the damping device.

The present invention provides for implant device delivery apparatuses and related methods of use. The delivery systems of the present invention incorporate a stretch resistant tube that advantageously makes the implant device, such as an embolic coil, stretch resistant while a delivery system is being used to position the implant device at a desired target site.

A delivery and detachment system for an implantable intravascular treatment device including a proximal inner tube telescopically receivable and axially slidable in a proximal direction within the lumen of the outer delivery tube. Specifically, the proximal inner tube comprises a proximal section and a distal section having different outer diameters forming a transition, wherein the distal section includes two distal section components connected by an axially separable region. When the axially separable region is axially separated: (i) the proximal section of the proximal inner tube is slidable in a proximal direction through the stopping member until the transition in the outer diameter of the first distal section component attached thereto engages a stopping member prohibiting axial movement in the proximal direction; and (ii) the restricting element maintaining in position the second distal section component within the outer delivery tube.
