Abstract: The present disclosure is directed to embodiments of an occlusive medical device including a frame and at least one closure coupled to the frame. The frame includes a distal annular flange having a radially outer surface and a radially inner surface, a proximal annular flange having a radially outer surface and a radially inner surface, and a waist portion extending between and connecting the distal annular flange to the proximal annular flange. The radially inner surface of the distal annular flange, the waist member, and the radially inner surface of the proximal annular flange define an unobstructed passageway through the frame. The at least one closure is configured to close the passageway to: (i) provide an occlusive effect, and (ii) enable subsequent access through the passageway.

Abstract: The present disclosure describes delivery cables for delivering a medical device and methods of making and employing the same. In one embodiment, a delivery cable includes a flexible inner core, a proximal outer coil, and a distal outer coil. The proximal outer coil has a first rigidity. The distal outer coil surrounds at least a portion of a distal section of the flexible inner core and has a second rigidity less than the first rigidity thereby, thereby reducing bias placed on the medical device by the delivery cable during deployment of the medical device. Relative dimensions of an outer diameter of the distal outer coil and an inner diameter of a delivery sheath for deploying the delivery cable reduce snaking of the delivery cable within the delivery sheath.

Abstract: A medical device for treating a target site includes a body extending from a proximal end to a distal end along a central longitudinal axis, the body including a proximal disc adjacent the proximal end, a distal disc adjacent the distal end, and a waist extending between and connecting the proximal and distal discs. The body further includes an inner layer formed from a first braided self-expanding material and an outer layer formed from a second braided self-expanding material, wherein the outer layer surrounds the inner layer and is independent from the inner layer.

The first braided self-expanding material includes a first number of wires and the second braided self-expanding material includes a second number of wires greater than the first number of wires.

Abstract: The present disclosure provides collapsible medical devices that are formed from a braided tubular member configured to allow the braided tubular member to be terminated into one or more marker bands while maintaining an open lumen from a proximal end to a distal end. The collapsible medical device including the braided tubular member can be easily pulled down into a delivery sheath or other delivery device so that it is suitable for use with a number of delivery devices. The marker bands, which provide one or more attachment points for a medical device/delivery system, are positioned at one or more locations on the braid such that the braid is fixed and cannot unravel, thus preventing entanglement between individual braid wires and malformation of the device.
