An apparatus for treating an aneurysm includes an occlusion element configured to be releasably coupled to an elongate delivery shaft and having a distal end, a proximal end, and a longitudinal axis extending between the distal end and the proximal end, the occlusion element configured to be delivered in a collapsed configuration and further configured to expand to an expanded configuration, the occlusion element comprising an inverted mesh tube having an outer layer and an inner layer, the outer layer transitioning to the inner layer at an inversion fold located at or adjacent the distal end of the occlusion element, the inversion fold defining an inner diameter, the occlusion element further comprising a maximum outer diameter, wherein the inner diameter is between about 35% to about 85% of the maximum outer diameter, and wherein an outer diameter of the occlusion element increases along the longitudinal axis to the maximum outer diameter.

The invention relates to an endoprosthesis (1), in particular a vascular or cardiac endoprosthesis (1), having a body (2) and also one or more thrombogenic elements (3) that are fixed to the endoprosthesis (1) and that are able to extend a distance away from the body outside the latter. The endoprosthesis comprises means (33) for selectively retaining the thrombogenic elements near the body (2). The release of the one or more thrombogenic elements, after the endoprosthesis has been fitted in place by a conventional method via a sheath, promotes thrombosis.

Aspects of the present disclosure include a simulated wound apparatus allowing a wearer to simulate injuries for purposes of casualty simulation and medical response training. Aspects of the present disclosure are directed towards a wearable medical training device and more specifically a device for training of hemorrhage control procedures on junctional bleeding. The present disclosure, when used by a live actor, may allow users to safely simulate hemorrhaging in some of the most challenging blood vessels in the most challenging anatomical locations such as the carotid artery, the axillary artery, and the femoral artery. The present disclosure may further provide the ability for users to safely perform hemorrhage control procedures, such as compression and ligation. The simulated wound of the present disclosure may be compressed to control hemorrhage. The simulated wound receptacle of the present disclosure may be packed with hemostatic or simple gauze to control hemorrhage. The simulated blood vessel of the device may be ligated with hemostats or other ligating instruments or material and bandaged with pressure dressings to control hemorrhage.

A left atrium appendage (LAA) isolator, including: a body sized and shaped to fit an at least partially inverted LAA of a human adult, wherein a distal end of said body defines a two-state sealing adaptor interface configured in a first state to apply a radially outward force against a wall of said LAA or against a wall of said LAA opening sufficient to anchor said body to the LAA wall, and in a second state the sealing adaptor interface is configured to apply a radially inward force on a portion of the inverted LAA positioned within said body.

An occlusion device with particular utility in occlusion of left atrial appendages is described. The occlusion device embodiments utilize an inflatable balloon or expandable element used to occlude the treatment site.

An apparatus includes a plurality of beads each defining a first opening and a second opening, a linking assembly, and a 3D printed magnetic element housed within a first bead of the plurality of beads. The linking assembly extends through the first opening and the second opening of each bead such that the beads and the linking assembly may be arranged in an annular arrangement to form a loop around an anatomical structure in a patient. The loop moves between a contracted configuration and an expanded configuration and is magnetically biased toward the contracted configuration. The 3D printed magnetic element is housed within a first bead of the plurality of beads. The 3D printed magnetic element include a composite of magnetic granules combined to generate a magnetic field. The magnetic field is generated by the 3D printed element and is configured to contribute toward the magnetic bias.

An apparatus includes a plurality of beads a linking assembly joining the beads together. The beads and the linking assembly are arranged in an annular arrangement and sized to form a loop around an anatomical structure in a patient. The loop may move between a contracted and expanded configuration. The loop is magnetically biased toward the contracted configuration by a magnetic bias of the beads. Each bead includes a housing having a first piece and a second piece that together define a magnetic chamber. A magnetic is within the magnetic chamber. A weld joins the first piece and the second piece while hermetically sealing the magnet chamber. The first piece of the housing includes a mounting feature integrated with a surface of the first piece. The mounting feature mates with a fixture to constrain the first piece of the housing as the weld is formed.

A medical device for treating a PFO is presented as well as a mechanism for its delivery, repositioning and/or removal. The device includes a wire or cable framework of six shape-memory cables formed into a right side having six loops that support a right side sail and a left side having six loops that support a left side sail. The right side loops and left side loops are connected together via waist members that extend between the right side and left side loops. Each cable is threaded through a through hole of a central post and pass through one of each of four types of connecting collars that establish the basic shape of the PFO device and retain the cables together to form a flexible and resilient PFO device.

The present disclosure provides improved medical devices for occluding a left atrial appendage. In one embodiment, the medical device includes a temperature activated memory shape foam that is constructed to transition from a first collapsed conformation to a second expanded conformation upon an increase in temperature such that it can expand to provide an occlusive benefit inside a left atrial appendage. In another embodiment the medical device includes a flowable thermoset that is injected into the left atrial appendage where is it cured so that it may assume the conformation of the left atrial appendage and provide an occlusive benefit.
