Apparatus and methods for retrieving a foreign body from a vasculature are provided. The devices can be Funnel-trap type retrieval devices. The devices can include a compressible support member extending from the distal end of an elongate shaft, the compressible support member having an expanded configuration, a compressed configuration, a plurality of independent elongate support elements that have a memory for the funnel-shaped expanded configuration, and a cover material that covers the compressible support member and forms a pocket configured for capturing the foreign body in the interior of the compressible support member.

Apparatus and methods for retrieving a foreign body from a vasculature

Disclosed are example embodiments of an endovascular coil having a twistedshape. The endovascular coil includes: a first loop; a second loop; and an inflection region where a portion of the first loop transitions into a portion of the second loop. The second loop is rotated about an axis parallel to the longitudinal axis of the first loop to create the twistedshape. The twist adds more randomness and variability to the filling behavior of the endovascular coil. The added randomness and variability enables the twistedcoil to better fill the void of irregular-shaped aneurysms than other conventional embolic coils.

Endovascular coil and method for making the same

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.

Occlusive device

Funnel-trap type delivery and/or retrieval devices for Inferior Vena Cava (IVC) filters or other medical implants are described in which the devices comprise two layers of braid with an axially support member. The support member may be interposed between braid layers or set inside the braid layers but interposed between heatset features. Delivery and/or retrieval devices, kits in which they are included, methods of use and methods of manufacture are all contemplated herein.

Instrument for delivery or capture of a medical device in a blood vessel

After a prolonged period in the body, an IVC filter can be substantially absorbed by the body. When this occurs, it can be very difficult and/or dangerous for the patient if the IVC filter is forcibly removed. Thus, it is desirable to have systems and methods for safely abandoning the removal procedure of the IVC filter. Example embodiments of an apparatus for safely abandoning the removal procedure of the IVC filter can include: a sleeve having a lumen and a first hole on a wall of the sleeve; a shaft slidably disposed within the lumen of the sleeve; a flexible distal extension comprising a braid structure with a first opening; and a first lasso encircling a portion of the first opening of the braid.

Systems and methods for implants and deployment devices

The embodiments described relate to retrieving temporary Inferior Vena Cava (IVC) filters and other endovascular implants or foreign bodies. Features are provided for effective actuation in closing an inner aperture of the embodiments.

Systems, devices, and methods for retrieval systems having a tether

Funnel-trap type devices are described that are made of shape-set (e.g., heatset) braid for delivery and/or retrieval of Inferior Vena Cava (IVC) filters or other medical devices. Delivery and/or retrieval devices, kits in which they are included, methods of use and methods of manufacture are all contemplated. Additional forming tooling, methods and device embodiment shapes are described herein.

Method for retrieval of a medical device

Methods and systems for retrieving temporary Inferior Vena Cava (IVC) filters, other medical implants, or foreign bodies are described. These methods may employ a locking sheath or a proximal-aperture capture feature for IVC filter (or other device) retrieval. One of the methods includes: passing an elongate member having a braided funnel-shaped distal extension through a sheath, where the braided funnel-shaped distal extension includes a distal bend to form a distal aperture and a flap that defines a proximal aperture; passing an end of the medical device through the distal aperture and then through the proximal aperture to capture the medical device; and covering the medical device with the sheath.

Method for IVC filter retrieval with multiple capture modes

IVC filter retrieval systems with interposed support members

Funnel-trap type devices or systems made of braid are described for capture and retrieval or, instead, capture and subsequent release of Inferior Vena Cava (IVC) filters or other medical devices. Delivery and/or retrieval devices, kits in which they are included, methods of use and methods of manufacture are all contemplated.

IVC filter retrieval systems with releasable capture feature

Shaping improvements for Inferior Vena Cava filter and retrieval systems

Funnel-trap type delivery and/or retrieval devices for temporary Inferior Vena Cava (IVC) filters or other medical implants or foreign bodies are described. These may employ a locking sheath or a proximal-aperture capture feature or features for IVC filter (or other device) retrieval.
