Abstract: A cardiac valve prosthesis including an armature for anchorage of the valve prosthesis at an implantation site. The armature defining a lumen for the passage of the blood flow and having a longitudinal axis, and a set of prosthetic valve leaflets supported by said armature and configured to move, under the action of blood flow, in a radially divaricated condition to enable the flow of blood through said lumen in a first direction, and in a radially contracted condition, in which said valve leaflets co-operate with one another and block the flow of blood through the prosthesis in the direction opposite said first direction. The armature including an annular part and a pattern of arches struts carried by said annular part, said pattern of arched struts having proximal ends connected to said annular part, and distal ends spaced axially from the proximal ends and opposite said annular part, a plurality of sets of anchoring formations configured to protrude radially outwardly of said annular part, each set being supported by a least one of said annular part and a corresponding arched strut, and a plurality of support posts, each support post being supported by adjacent arched struts, wherein the sets of anchoring formations alternate with the support posts around said longitudinal axis.

Abstract: A delivery device for a collapsible prosthetic heart valve includes an inner shaft, an outer shaft, and a distal sheath. The distal sheath may be disposed distal to the outer shaft and about a portion of the inner shaft to form a compartment with the inner shaft. The compartment may be sized to receive the prosthetic heart valve. The inner shaft and the distal sheath may be movable relative to one another. A spine may extend along the outer shaft, the spine biasing the outer shaft so that the outer shaft tends to bend in a pre-determined direction.

Abstract: A method is disclosed for removing a vascular occlusion, such as a clot, from a blood vessel. A tubular sheath is inserted into the vessel and a self-expanding Nitinol mesh filter is deployed from a distal end of the tubular sheath at a location proximal to a clot. An inner catheter is advanced through the tubular sheath and through the mesh filter for contacting the clot. An expandable agitation element is provided along a distal end portion of the inner catheter for cutting or chopping the clot, thereby facilitating removal of the clot and improving blood flow through the vessel. Resulting clot particles are captured by the mesh filter. Negative pressure may be applied along a proximal end portion of the sheath for aspirating remaining particles. Certain embodiments of the method are well-suited for treating deep vein thrombosis and do not require the use of thrombolytic drugs.

Abstract: A sacrocolpopexy support has a head section extending from a first end portion to a second end portion, and a leg section having a first leg portion placed on and in longitudinal alignment with a second leg portion. A first connector secures the leg section to the second end portion of the head section. A second connector secures the first leg portion to the second leg portion to form a closed joint that defines a space between the first leg portion and the second leg portion. An end of the second end portion of the head section terminates at a location exterior to the closed joint outside of the space between the first leg portion and the second leg portion.

Abstract: Methods of implanting a device in the lumen of a blood vessel are described. The method includes providing a microcatheter and a device. The device includes a first hub, a second hub, a support structure including a plurality of struts disposed between the first hub and the second hub, and a layer of material disposed over the plurality of struts. The support structure has a low profile, radially constrained state with an elongated tubular configuration suitable for delivery from a microcatheter. The support structure also has an expanded state, a smooth outer surface, and has an axially shortened configuration relative to the radially constrained state. The microcatheter is advanced to a region of interest within the blood vessel. The support structure is advanced through the lumen of and out the distal end of the microcatheter where it expands to the expanded state.

Abstract: The present invention provides an implant that includes inflatable anchors that are configured to assume an inflated state and a relaxed state. The implant includes a tubular member mechanically coupled to one or more anchors of the inflatable anchors. The tubular member includes a lumen that provides a passageway for circulating a fluid through the one or more of the plurality of inflatable anchors and allow them to protrude and pierce through bodily tissues. In an embodiment, the implant may include a plurality of bi-directional barbs instead of the inflatable anchors. The plurality of barbs may be activated by a flexible member such that the activation is configured to cause anchoring of the barbs into soft tissues during a surgical procedure. The present invention provides a method for placing an implant. The method includes delivering the implant inside a body along a pathway through an opening proximate sacrum and attaching a first portion of the implant to an anterior vaginal wall, attaching a second portion of the implant to a posterior vaginal wall and attaching a third portion of the implant to a tissue proximate the sacrum.

Abstract: A deployment apparatus and method for deploying one or more stents to a bifurcated vessel is provided. The invention is particularly suited for T-type bifurcated vessels where a side branch extends from a main branch. The deployment apparatus has a primary inflatable portion for engagement within the main branch and a secondary inflatable portion for engagement within the side branch. A main stent is arranged on the primary inflatable portion and radially expanded within the main branch while the secondary inflatable portion maintains registration with the side branch. A side branch stent is then arranged on the secondary inflatable portion and expanded within the side branch while the primary inflatable portion maintains registration with the expanded main stent. A bifurcated stent system suitable for bifurcated lesions is also provided comprising a side branch stent with a shaped end designed to engage a similarly shaped side opening in a main stent.
