Embodiments of the present disclosure provide a removable embolic protection device for deployment at a body vessel, as well as systems and methods for implanting the device within a vessel of a patient.

A body of the device to position a coronary stent or pull a catheter transducer for intravascular ultrasound is composed of a front and a rear portion each of which comprises two similar halves, a ring on the front smooth portion of the body and a brace over the rear portion of the rear portion of the body. The rear portion of the body overlaps the front portion of the body. The front portion of the body is truncated on one side thereof and continuously extends on the opposite side thereof in the form of a smooth cylindrical portion of a smaller diameter and a runner guide. A cylindrical slot with point elements is provided along the circumference of the cylindrical portion of the front portion of the body on the side of the runner guide. A cylindrical brace is mounted on the rear portion of the body.

Systems and methods are provided for removing air from a medical device, such as a stent-graft and/or its delivery device. In an exemplary embodiment, the stent-graft or its delivery system or both are exposed to perfluorocarbon, by immersing the stent-graft or flushing the delivery device to remove air from the stent-graft. Optionally, the stent-graft and/or delivery system may be flushed multiple times, e.g., with perfluorocarbon before or after flushing with carbon dioxide, saline, a bio-inert gas, and the like. Thereafter, the stent-graft may be introduced into a patient's body and deployed at a target location, such as the site of an abdominal aortic aneurysm.

The invention relates to a safety cartridge (1) for a removable vena cava filter (20), having a proximal end (2) and a distal end (3) and having an inner channel (4) extending between the ends. The cartridge is characterized in that it comprises, on the distal end (3) thereof, a linking device (5) for forming a link with a catheter (30) and, in the inner channel thereof, a projection (6) having a limited size in the axial direction of the cartridge (1) so as to locally reduce the cross-section of the channel (4).

Devices, systems and methods for filtering embolic particles that may be generated from a medical procedure including protection of the major branching vessels from the aorta, and catches and filters emboli that may be generated during the TAVR procedure. The filter devices disclosed herein form an improved seal against the vessel wall that is activated by flowing blood. Devices described herein also allow for the closing of the ends of the filter device after capture of emboli, providing further security against accidental loss of emboli post capture.

A multipurpose handle incorporated into a medical device delivery system. The multipurpose handle includes an elongate handle body, an actuation button, and a locking member. The elongate handle body has a proximal end extending to a distal end, which defines a longitudinal axis. The elongate body further includes a cutout that creates a movement space therein in which the actuation button is disposed and is connected to a medical device. The actuation button is movable within the cutout along the longitudinal axis and rotatable within the cutout. The locking member is connected to the elongate handle body and movable between a locked position and unlocked position. The locking member may be in contact with the actuation button and be configured to restrict the movement of the actuation button along the longitudinal axis when in the locked position.

A retrieval catheter operable by a single clinician that will neither displace a deployed stent nor cause undue trauma to the vascular lumen or lesion. The retrieval catheter may be sized to accommodate both a guidewire and a balloon wire. The retrieval catheter is easy to navigate through tortuous passageways and will cross a previously deployed stent or stent-graft easily with minimal risk of snagging on the deployed stent or stent graft. The sheath and dilator are adapted to allow a guidewire or balloon wire to pass through the walls of both and to allow the sheath and dilator to move axially with respect to each other.

A treatment device (500) is provided including a shaft (507), an expandable member, a first elongated control member (508) and a second elongated control member (502). The expandable member can further include at least a first controllable portion (504) and a second controllable portion (503), where the expandable member, including the first controllable portion and the second controllable portion, is configured to transition between at least a partially retracted configuration and an expanded configuration under control of at least the first elongated control member (508). Further still, the first controllable portion can be configured to transition between at least a partially retracted configuration and an expanded configuration, while the second controllable portion (503) is configured to remain substantially unchanged, under control of at least the second elongated control member (502).

A device for retrieval of a vena cava filter is provided. The retrieval device has, approximately, an umbrella shape and consists of a central shaft; a plurality of frame struts, attached to frame strut attachment points on the central shaft and disposed radially about the central shaft; and a plurality of snare wires. The retrieval device has a collapsed configuration for insertion and removal from a blood vessel of a patient and an expanded state for capturing an intravascular filter in the blood vessel of the patient. The plurality of snare wires provides multiple points at which a vena cava filter, particularly one that has become misaligned during deployment or treatment, can be caught. The frame struts can be substantially sinusoidal in shape and made of shape memory metal, such as Nitinol. The snare wires can be made of a biocompatible material such as silk, polyester, polypropylene, or nylon.

Catheter-delivered endovascular medical devices are described. The devices may include a pull wire attached to a deployable dual basket system. The deployable dual basket system may include a proximal basket and a distal basket that are connected by basket connector tether memory metal strips that rotate/twist relative to the longitudinal axes of the basket and form flex points of the system. The proximal basket and the distal basket may be comprised of a plurality of cells and the proximal basket may taper at its proximal end and the distal basket may be tapered at its distal end. Methods of using and making the devices are also described.
