Embodiments of an expandable sheath can be used in conjunction with a catheter assembly to introduce a prosthetic device, such as a heart valve, into a patient. Such embodiments can minimize trauma to the vessel by allowing for temporary expansion of a portion of the introducer sheath to accommodate the delivery apparatus, followed by a return to the original diameter once the prosthetic device passes through. Some embodiments can include a sheath with inner and outer layers, where a folded portion of the inner layer extends through a slit in the outer layer and a portion of the outer layer overlaps the folded portion of the inner layer. Some embodiments include an elastic outer cover positioned outside the outer layer. Embodiments of the present expandable sheath can avoid the need for multiple insertions for the dilation of the vessel, thus offering advantages over prior art introducer sheaths.

The invention is a device, and method for deploying same, configured for placement in a body lumen such as a coronary sinus, as may be desired to repair a mitral valve. The device includes a first anchor, a second anchor, and a bridge. The anchors are configured to delivered to a desired deployment site within the body lumen in a collapsed or contracted condition, and then be deployed by expanding the anchors into contact with the walls of the body lumen. One or more of the anchors may be configured to be radially collapsible after initial deployment in order to permit the anchor(s) to be repositioned in or removed from the body lumen. An anchor may be collapsible in response to a distal force applied to a portion of a proximal end thereof. A catheter for use with the implant is configured to deliver the implant to the site with the anchors in their respective collapsed configurations, and to release the anchors to permit them to expand into contact with the walls of the body lumen. The catheter is configured to apply a proximal force to one or both anchors, which may be applied via a cinch wire. The catheter may also be configured to apply a distal force against a portion of the proximal end of one or more of the anchors.

In one embodiment, a neck bridge for bridging the neck of an aneurysm includes a junction region, a number of radially extending array elements attached to the junction region, and a cover attached to one or both of the junction region and an array element. The array elements are configured to be positioned within the aneurysm after the neck bridge is deployed from a delivery device. In a second embodiment, the neck bridge includes a junction region and a braided or mesh-like structure secured to the junction region. The braided or mesh-like structure is made from an elastic material.
