  • Patent number: 10327781
    Abstract: A system for treatment of an aneurysm includes an intrasaccular device that can be delivered using a catheter. The device can include at least one expandable structure adapted to transition from a compressed configuration to an expanded configuration when released into the aneurysm. The expandable structure can have a specific shape or porosity. Multiple expandable structures can also be used, in which case each of the expandable structures can have a unique shape or porosity profile. The morphology of the aneurysm and orientation of any connecting arteries can determine the type, size, shape, number, and porosity profile of the expandable structure used in treating the aneurysm.

  • Patent number: 10314593
    Abstract: An implant can include a single- or dual-layer braided body having a variable porosity. In a dual-layer body, first and second longitudinal sections, having respective first and second porosities, can be overlapped such that the first and second porosities overlap each other. The dual-layer construction can cumulatively provide a third porosity at a distal portion and a fourth porosity at a proximal portion. The third and fourth porosities can each be greater than each of the first and second porosities.

  • Publication number: 20170367704
    Abstract: Delivery and detachment of an implant can be enhanced by a retraction mechanism to secure portions of a delivery wire within an interior space of the implant. A delivery system can include an implant having a proximal end portion. A delivery wire can include (i) a detachment zone proximal to the proximal end portion and (ii) a distal region distal to the proximal end portion. An expansion member can be located between the proximal end portion and the distal region of the delivery wire. The expansion member can be biased to move the distal region of the delivery wire distally away from the proximal end portion when severed at the detachment zone.

  • Publication number: 20170367709
    Abstract: Treatment of an aneurysm or other vascular defect can be facilitated or enhanced by an implant delivered with a thermally activated detachment system. A delivery system can include an implant with a proximal portion that defines a port. A pusher device can include arms extending distally from a junction of the pusher device and through the port, with distal sections of the arms disposed within the implant. The arms can, at a certain temperature, transition from engagement with the implant to a shape that facilitates release of the implant. Additionally or alternatively, a coil can engage an outer surface of the implant at the proximal portion and transition to a shape that facilitates release of the implant.

  • Publication number: 20170281194
    Abstract: An occlusive device for occluding a target area can include an elongate member having opposing first and second side edges extending longitudinally along the member and a member width. The member can have a collapsed configuration in which the first and second side edges are curled toward each other about a longitudinal axis of the member. Further the member can have an expanded configuration in which the member form a series of loops and the first and second side edges uncurl to be spaced apart from each other.

  • Publication number: 20170164951
    Abstract: Systems and devices for endovascular treatment of intracranial aneurysms are described. Various configurations of coiled implants may be used as stenting devices or aneurysm coils. The implants include one or more filaments wound about a longitudinal axis to form a generally tubular shape. Lateral flexibility of the implants may be manipulated by, for example, adjusting a pitch between adjacent filaments, using different materials for the filaments, employing different filament cross-sectional shapes, grouping filaments into pluralities of varying flexibilities, and nesting inner coils within outer coils.

  • Publication number: 20170079662
    Abstract: An implant can include a frame and a mesh component coupled to the frame. The mesh component can define a first porosity, and the frame can define a frame porosity. The combined porosity of the mesh component and the frame can restrict blood flow into the implant.

  • Publication number: 20160022445
    Abstract: An aneurysm embolization device can include a body having a single, continuous piece of material that is shape set into a plurality of distinct structural components. For example, the device can have an expandable component and an atraumatic tip portion extending therefrom. Further, the tip portion can be configured to enable the device to be implanted within the aneurysm while tending to mitigate risk of puncturing the aneurysm dome or otherwise assist in framing the aneurysm in advance of placement of additional embolic material.

  • Publication number: 20100081868
    Abstract: Systems, methods and devices are provided for treating heart failure patients suffering from various levels of heart dilation. Such heart dilation is treated by reshaping the heart anatomy with the use of shape memory elements. Such reshaping changes the geometry of portions of the heart, particularly the right or left ventricles, to increase contractibility of the ventricles thereby increasing the stroke volume which in turn increases the cardiac output of the heart. The shape memory elements have an original shape and at least one memory shape. The elements are implanted within the heart tissue or attached externally and/or internally to a surface of the heart when in the original shape. The elements are then activated to transition from the original shape to one of the at least one memory shapes. Transitioning of the elements cause the associated heart tissue areas to readjust position, such as to decrease the width of the ventricles.

  • Publication number: 20080293995
    Abstract: Systems, methods and devices are provided for treating heart failure patients suffering from various levels of heart dilation. Heart dilation treated by reshaping the heart anatomy with the use of magnetic forces. Such reshaping changes the geometry of portions of the heart, particularly the right or left ventricles, to increase contractibility of the ventricles thereby increasing the stroke volume which in turn increases the cardiac output of the heart. The magnetic forces are applied with the use of one or more magnetic elements which are implanted within the heart tissue or attached externally and/or internally to a surface of the heart. The various charges of the magnetic forces interact causing the associated heart tissue areas to readjust position, such as to decrease the width of the ventricles. Such repositioning is maintained over time by the force of the magnetic elements, allowing the damaging effects of heart dilation to slow in progression or reverse.
