摘要:
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.

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.

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.

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.

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.
