Appl. No.:

10/835153

Inventors:

Jeffrey W. Allen - Santa Rosa CA, US
David S. Brin - Topsfield MA, US
Chris M. Coppin - Carlsbad CA, US

Assignee:

Medtronic Vascular Inc. - Santa Rosa CA

International Classification:

A61F 2/06

US Classification:

623 218, 606200

Abstract:

The percutaneously delivered temporary valve assembly of the present invention, and method of using the same, provides an elongate element and a temporary valve disposed on the elongate element. The temporary valve can comprise struts and a membrane attached to the struts. The elongate element can include at least one lumen. The percutaneously delivered temporary valve assembly can be used to replace an aortic valve by locating a temporary valve in a patient's ascending aorta; deploying the temporary valve; removing the native aortic valve past the temporary valve; implanting the prosthetic aortic valve past the temporary valve; collapsing the temporary valve; and removing the temporary valve from the patient. The temporary valve can be sized to the patient and can be left in place while the prosthetic aortic valve heals in.

International Classification:

A61F 2/06

US Classification:

623 115

Abstract:

The present invention is an intralumenal stent device made up of two or more elements. Each element has undulations forming peaks and valleys and is formed from a repeating series including a long segment, a first midsized segment, a short segment, and a second midsized segment. These elements are aligned on a common axis and are connected directly to an adjacent element by a connection. The stent incorporates the advantages of having both long and short segments into a single element.

International Classification:

A61F 2/06

US Classification:

623 115, 424426

Abstract:

A balloon-expandable stent formed from a customized alloy formulation. The stent alloy has a either a high, variable or no work hardening rate, very high modulus of elasticity (Young's modulus), and a low yield point. A stent constructed of a material with this combination of properties undergoes significant plastic deformation upon deployment in vivo to its implantation diameter and exhibits minimum recoil for better sizing. The plastic deformation also raises the subsequent yield point of the stent material resulting in a stronger stent upon implantation that is more resistant to vascular loading.

Abstract:

The perivascular leak repair system, and method of using the same, of the present invention provides a sealant reservoir with a repair catheter operably attached; a flow control device disposed between the sealant reservoir and the repair catheter, and the flow control device responsive to a flow control signal; a heart phase detector generating a diastole phase signal; an injection switch generating a injection signal; and a flow controller responsive to the diastole phase signal and the injection signal, and generating the flow control signal. A method of sealing a perivascular leak comprises identifying the perivascular leak; inserting a repair catheter to the perivascular leak; injecting sealant at the perivascular leak; and removing the repair catheter. The sealant can be injected when the heart is in diastole to sweep the sealant into the perivascular leak.

US Classification:

623 138, 623 144, 623 145

Abstract:

A bioresorbable endoluminal prosthesis for placement in a body lumen having a stent substrate of a first metallic material that has a lower electrical potential than a standard reference electrode. The stent substrate is coated with a biodegradable polymer having a second metallic material dispersed therein, wherein the second metallic material has a higher electrical potential than the standard reference electrode. After implantation of the stent within the body lumen, the second metallic material is present in the polymeric coating in a sufficient concentration to cause galvanic corrosion of the first metallic material such that over time the stent substrate is bioresorbed.

US Classification:

206438, 206370, 623 211

Abstract:

A packaging system is disclosed for shipping a prosthetic tissue valve in a storage solution and preparing and loading of the bioprosthetic valve onto a catheter-based delivery system. The packaging system includes a fluid tight container filled with the storage solution attached to a delivery catheter, wherein the container surrounds the prosthetic tissue valve that is in a pre-loaded position on the delivery catheter during shipment and storage. The prosthetic tissue valve may include an attachment mechanism that attaches to the delivery catheter to properly position the tissue valve for loading within the delivery catheter. In another embodiment where the prosthetic tissue valve is not attached to the delivery catheter during shipment, the attachment mechanism may interact with the prosthetic tissue valve shipping container to prevent the bioprosthetic valve from moving during shipment.
