A bioabsorbable wire material includes manganese (Mn) and iron (Fe). One or more additional constituent materials (X) are added to control corrosion in an in vivo environment and, in particular, to prevent and/or substantially reduce the potential for pitting corrosion. For example, the (X) element in the Fe—Mn—X system may include nitrogen (N), molybdenum (Mo) or chromium (Cr), or a combination of these. This promotes controlled degradation of the wire material, such that a high percentage loss of material the overall material mass and volume may occur without fracture of the wire material into multiple wire fragments. In some embodiments, the wire material may have retained cold work for enhanced strength, such as for medical applications. In some applications, the wire material may be a fine wire suitable for use in resorbable in vivo structures such as stents.

A medical device, which may be adapted for delivering and/or recapturing an implantable implant, includes an elongate sheath and a rigid member that is secured relative to the elongate sheath. The elongate sheath includes an inner polymeric liner, an outer polymeric sheath and a reinforcing braid that extends within the outer polymeric sheath. The reinforcing braid includes a plurality of wire ends that extend beyond a distal edge of the rigid member in order to protect the implantable implant from being damaged by the rigid member in the event that the inner polymeric liner becomes damaged.

A stent having a main linear strut and at least two secondary struts. The main linear strut includes an outer member and an inner member. A distal end of one secondary strut may be attached to a distal end of the inner member. A proximal end of a secondary strut may be attached to a proximal end of the outer member. The ends of the secondary struts that are not attached to the inner and outer member may be joined. Methods of delivering such a stent and collapsing and withdrawing such a stent are also disclosed.

The invention discloses a stent graft used for interventional treatment of abdominal aortic disease, comprising a tube body composed of a tubular covering and a plurality of annular stents, and the tube body comprises a first tube body and a second tube body that arranged in sequence from the proximal end to the distal end, wherein the diameter of the first tube body is greater than diameter of the second tube body; the first tube body and the second tube body are connected by a transition section as a whole; the diameter at central part of the transition section is smaller than the diameter of the proximal end of the transition section and the diameter of the distal end of the transition section; a plurality of fenestrations are disposed on the first tube body and the transition section. The invention provides a stent graft having a smaller diameter of the portion near the branch vessels or branch stents after released, and has more space for accommodating branch vessels or branch stents for interventional treatment of abdominal aortic diseases.

A filter device for implantation in a gallbladder, comprising: a filter portion configured to filter gallstones of a certain minimum size to prevent them from exiting the gallbladder through an opening of the gallbladder; a blocking portion configured to push gallstones of a certain minimum size away from an opening of the gallbladder where the blocking portion is located distally from the filter portion with respect to the opening of the gallbladder; and, where the blocking portion and the filter portion do not attach to, or apply expansive radial force on, a wall of the gallbladder.

Aspects of the present invention relate to a delivery device for locating an expandable implant for treating BPH within the prostatic urethra of a patient. The delivery device comprises an inner tube and an outer sleeve movable relative to the inner tube between a stored position and a deployed position. The outer sleeve surrounds the inner tube to define an annulus therebetween and the expandable implant is retained within the annulus when the outer sleeve is in the stored position.
