Abstract: A device and a method for increasing or restoring a flow in a body lumen are provided. The device and the method may treat conditions related to a stroke, such as an ischemic stroke, by removing an occlusion from a blood vessel and/or reopen a blood vessel. The device may comprise a pusher tube and an expandable compartment. The expandable compartment may comprise a control element, a reconfigurable element, and supportive element. The supportive element is configured to adjust a radial force and a configuration of the reconfigurable element, thereby allowing highly efficient removal of an occlusion from a blood vessel and/or reopen a blood vessel with least or no damage to the body lumen.

Abstract: A device and a method for increasing or restoring a flow in a body lumen are provided. The device and the method may treat conditions related to a stroke, such as an ischemic stroke, by removing an occlusion from a blood vessel and/or reopen a blood vessel. The device may comprise a tubing compartment, a central wire, and an engaging compartment. The engaging compartment may comprise a distal engaging element and a proximal engaging element. A clot or occlusion present in the body lumen such as an artery may be engaged in and/or between the distal and proximal engaging elements. Further, the positions of one or both of the engaging elements and the distance therebetween can be adjusted to ensure the engagement of the clot or occlusion.

Abstract: An implant assembly comprises an elongated pusher member, and an implantable device (e.g., a vaso-occlusive device) mounted to the distal end of the pusher member. The implant assembly further comprises an electrolytically severable joint disposed on the pusher member, wherein the implantable device detaches from the pusher member when the severable joint is severed, and a return electrode carried by the distal end of the pusher member (e.g., a coil disposed about the pusher member) in proximity to, but electrically isolated from, the severable joint. The implant assembly further comprises a terminal carried by the proximal end of the pusher member in electrical communication with the severable joint.

Abstract: Baskets with atraumatic distal tips allow the capture of material from difficult-to-reach areas of the body, while reducing the risk of tissue damage.

Abstract: Devices for loading a collapsible implant onto a delivery catheter. In one aspect, a loading device comprises an outer tubular structure and an inner tubular structure. The outer tubular structure comprises a narrowing passage configured to receive a catheter at one end and a collapsible implant at another end. The inner tubular structure is configured to move slidably and co-axially within the outer tubular structure. The inner tubular structure comprises a carrier pin configured to move within the narrowing passage as the inner tubular structure slides into the outer tubular structure. The sliding of the inner tubular structure into the outer tubular structure causes an implant mounted on the carrier pin to collapse as the implant moves through the narrowing passage and into the distal end of a catheter.

Abstract: Disclosed herein are vaso-occlusive devices for forming occluding the vasculature of a patient. More particularly, disclosed herein are vaso-occlusive devices comprising at least one polymer structure and methods of making and using these devices.

Abstract: A medical retrieval device includes a basket formed of two or more loops. The basket may be used to retrieve material (e.g., a urinary stone) from a body. The basket opens and closes for end-encapsulation of a stone and is strengthened by support members that interconnect the basket loops. A captured stone may be released from the basket with the basket still in the body by opening the loops.

Abstract: A medical device includes a handle, a sheath, and an object-engaging unit. The distal end portion of the sheath is strong enough to resist being deformed by the object-engaging unit, yet another portion of the sheath is flexible enough to bend sufficiently.

Abstract: A device for delivering an occlusive element such as a vaso-occlusive coil includes an elongate sheath. An elongate releasing member having a distal tip or end is moveable within a lumen of the elongate sheath. A filament is provided having first and second ends with each end being fixed relative to the elongate sheath to form a loop segment. The loop segment of the filament is passed through a securing member located on the proximal end of the occlusive element. The distal tip of the elongate releasing member is inserted into the portion of the loop segment that passes through the securing member to lock the occlusive element relative to the elongate sheath. The occlusive element is released by pulling the elongate releasing member proximally to retract the distal tip from the loop segment of the filament.

Abstract: A device for delivering an occlusive element includes an elongate pusher member having a lumen. A locking member is disposed within the lumen of the elongate pusher member. A moveable elongate releasing member is disposed within the lumen of the elongate pusher member. A filament is secured to the distal end of the elongate releasing member. The occlusive member is locked to the elongate releasing member when the filament passes through a securing member on the occlusive member and is pinched or wedged between the locking member and the elongate releasing member. The occlusive element is in an unlocked state when the elongate releasing member is retracted proximally relative to the elongate pusher member. The filament, along with the elongate releasing member, are retracted proximally until the filament is detached or uncoupled from the securing member of the occlusive member.

Abstract: A device for delivering an occlusive element includes an elongate pusher member having a lumen extending between distal and proximal ends. An elongate releasing member is slideably disposed within the lumen of the elongate pusher member. A retaining member is disposed on the distal end of the elongate pusher member and includes a finger portion having an aperture sized to receive the distal end of the elongate releasing member. An occlusive element such as a coil is provided and includes a securing member positioned at a proximal end thereof. The securing member is releasably secured to the finger portion of the retaining member. The securing member is secured to the finger portion when the elongate releasing member is disposed in the aperture of the finger portion and unsecured when the elongate releasing member is retracted proximally from the aperture of the finger portion.
