An occlusion device for occluding a cavity defined by a body is provided, and includes first and second laterally-expandable portions each formed of a woven tubular fabric and having opposed proximal and distal ends. The first portion is insertable into the cavity so as to be substantially disposed therein upon lateral expansion thereof. A connective element tethers the distal end of the first portion and the second portion, and is cooperable therewith to form a collapsible assembly extending along an insertion axis. Retention members, operably engaged with each of the first and second portions and spaced apart about a laterally outward surface thereof, are adapted to engage the body, after insertion of the collapsed assembly, second portion-first, into the cavity, and subsequent lateral expansion of the first and second portions, so as to retain the assembly substantially within the cavity. An associated deployment method is also provided.

Provided herein is an occlusion device comprising: (a) a substantially solid marker band having an inner and outer diameter, a proximal end, and a distal end; and (b) a resilient mesh body attached within the marker band, wherein the body is a length y, and wherein the body comprises a bolus of additional resilient mesh material of a length x, wherein y is greater than x, and wherein the body extends distally from the marker band having a first delivery shape and a second expandable deployed shape. Also provided herein is a kit comprising the occlusion device disclosed herein and a means for delivery thereof. Methods of manufacture and use of the occlusion device disclosed herein are also disclosed.

An exemplary occlusion device is disclosed. In various embodiments, the exemplary occlusion device includes a cap chamber and a bulb chamber for occluding a left atrial appendage (LAA). In particular embodiments, after delivery to the LAA, the cap chamber and the bulb chamber are each inflated via various amounts of fluid(s) to occlude the LAA.

A medical device for removing a material from a hollow anatomical structure is provided. The device may include a shaft member. The device may include an expandable centering element near the distal end of the device. The device may include a macerator element either attached to the shaft or independent and freely moveable from the shaft. Alternatively, the device may include a rotating wire attached to the macerator element. The device may include an aspiration lumen in for removal of material. The device may include a drive shaft attached to a motor and used to rotate the macerator element. The device may be used in combination with a distal occlusion element, which may be either a radially expandable filter or balloon member.

The present invention teaches the uses of a disc shaped mesh intrasaccular occlusion structure, with optional supplemental hydrogel, which is designed to implement an endovascular treatment to facilitate saccular aneurysm treatment while ameliorating or eliminating aneurysm recurrence.

The group of inventions relates to medical technology, and more particularly to means for dynamic virtual articulation. One of the inventions is a method for using a dynamic virtual articulator for simulating occlusion during a change in the initial position of the lower jaw or fragments thereof, and for modeling the position of the teeth in relation to one another and the position and shape of false teeth, said method being carried out with the aid of a computer. The method includes the following steps: providing a virtual articulator comprising a virtual three-dimensional model of the upperjaw and dental arch and a virtual three-dimensional model of the lower jaw and dental arch, resembling the upper jaw and upper teeth and the lower jaw and lower teeth, respectively, of the patient; and providing simulated movements of the virtual upper jaw and the virtual lower jaw in relation to one another for simulating dynamic occlusion, during which penetrating and non-penetrating contact mayoccur between teeth in the virtual upper and virtual lower jaw. Providing the virtual articulator further includes providing virtual three-dimensional models of the temporomandibular joints, resembling the heads of the lower jaw, the mandibular fossae, and the articular tubercles of the temporal bones, and carrying out simulated movements of the jaws in relation to one another is preceded by clinically or virtually setting initial and final positions. Furthermore, the virtual surfaces of the heads of the lower jaw and the virtual surfaces of the articular tubercles and the mandibular fossae of the temporal bones of the patient are disengaged. A second invention is a non-volatile machine-readable medium with a stored code containing instructions which, when executed, allow the proposed method to be carried out. The group of inventions makes it possible to provide a virtual articulator that simulates as closely as possible the actual processes occurring in the patient's mouth.
