A medical device delivery system comprises a catheter having a catheter shaft with a proximal region and a distal region. The catheter shaft has a pull wire lumen therein. An expandable medical device is disposed about medical device receiving region of the catheter shaft. The expandable medical device has a reduced configuration and an expanded configuration. The system further comprises a retractable retaining wire, at least a portion of which is coiled about the expandable medical device and retains the expandable medical device in the reduced configuration. One end of the retractable retaining wire terminates in a pull-wire. The pull-wire extends into the pull-wire lumen to the proximal region of the catheter shaft.

Internal restraint for delivery of self-expanding stents

Coils, such as embolic coils, can include a substrate; and a porous material supported by the substrate. Related methods, devices, and compositions, can include: injecting a material into a container containing the coil; and forming the material into a coating that is supported by the coil and/or contacting the coil with a composition comprising a first polymer and a gelling precursor; and forming the composition into a coating that is supported by the coil.

Forming coils

A device for the occlusion of a vascular defect includes a first sheet and a second sheet which may be formed from a material which is the same as or different from the first sheet. At least one sheet functions as a securement member, and at least one sheet functions as an occluding member. The first sheet may be replaced by an alternative securement structure. At least one sheet may be coated with a biocompatible material for promoting integration with the vasculature and/or healing of the vascular defect.

Device and method for treatment of a vascular defect

Apparatus and methods for treating a wall of an aneurysm formed in a vessel includes introducing a tubular member into the body lumen until a distal end of the tubular member is located within the aneurysm. A fluid is delivered via a lumen of the tubular member into the aneurysm to at least partially de-endothelialize the wall of the aneurysm, thereby causing an endothelium of the wall to generate fibrous tissue to strengthen the wall of the aneurysm.

Systems and methods of de-endothelialization

Compositions comprising absorbable implantable vaso-occlusive members are described. Also described are methods of making and using these absorbable vaso-occlusive compositions.
