Stent and stent delivery
A vascular prosthesis (e.g., stent), and packaging and delivery system to selectively deliver a vascular prosthesis are described. In some embodiments, the vascular prosthesis utilizes a low porosity and high porosity section, and the packaging and delivery system allows the prosthesis to be delivered such that the position of the low porosity and high porosity sections of the prosthesis can vary.
Surgical implant devices and methods for their manufacture and use
A method of implanting a device in a heart includes inserting an implant into a blood vessel with a delivery apparatus. The implant includes a stent member and an adjustment member. The stent member is circumferentially expandable and contractible. The adjustment member is coupled to the stent member. The delivery apparatus includes a rotatable shaft and a locking mechanism coupled to an end portion of the shaft. The shaft of the delivery apparatus is releasably coupled to the adjustment member of the implant by the locking mechanism of the delivery apparatus. The method further includes positioning the implant at an implantation location within a heart by manipulating the delivery apparatus, and rotating the shaft of the delivery apparatus relative to the stent member of the implant to actuate the adjustment member of the implant. Actuating the adjustment member results in circumferential expansion or contraction of the stent member.
SHUNT FOR REDISTRIBUTING ATRIAL BLOOD VOLUME
Systems and methods for implanting a shunt for regulating blood pressure between a patient's left and right atria are provided. The shunt comprises an anchor having a neck region, first and second end regions, and a conduit affixed with the anchor formed of a biocompatible material that is resistant to transmural and translation tissue ingrowth and that reduces a risk of paradoxical embolism. The shunt may be advanced through the sheath until the first region protrudes from the sheath and self-expands within the left atrium. The shunt and the sheath may then be retracted until the first region contacts the left side of the atrial septum. The sheath may further be retracted until the counterforce exerted by shunt tension on the atrial septum overcomes the friction of the retained portions of the shunt such that the second region is exposed from the sheath and self-expands within the second atrium.
DEVICE, SYSTEM, AND METHOD FOR TRANSCATHETER TREATMENT OF VALVULAR REGURGITATION
Devices are disclosed for use in the transcatheter treatment of mitral valve regurgitation, specifically a coaptation assistance element for implantation across the mitral valve and an edge to edge device. Methods are disclose for reducing mitral valve regurgitation at low left ventricle pressure and high left ventricle pressure during the cardiac cycle. Devices are disclosed for use in the transcatheter treatment of mitral valve regurgitation, specifically a coaptation assistance element for implantation across the mitral valve with an adaptive coaptation element.
Implantable devices and techniques for oncoplastic surgery
Described herein are devices for placement in surgically created soft tissue spaces, potential spaces, or cavities. The implantable devices generally include a bioabsorbable body having an open framework that facilitates attachment of tissue thereto in a manner that helps avoid post-surgical deformities. Methods for using the implantable devices in oncoplastic surgery are further described.
Modular aortic arch prosthetic assembly and method of use thereof
A prosthetic assembly configured for endovascular placement within an aortic arch and method of use thereof. The prosthetic assembly includes a proximal aortic stent-graft prosthesis configured to be positioned within a proximal portion of the aortic arch adjacent to the brachiocephalic artery, a distal aortic stent-graft prosthesis configured to be positioned within a distal portion of the aortic arch adjacent to the left subclavian artery, a first branch stent-graft prosthesis configured to be positioned within the brachiocephalic artery and a second branch stent-graft prosthesis configured to be positioned in one of the left common carotid and the left subclavian artery. When deployed, a proximal end of the first branch stent-graft prosthesis is disposed within a lumen of the proximal aortic stent-graft prosthesis to proximally displace the ostium of the brachiocephalic artery. When deployed, a proximal end of the distal aortic stent-graft prosthesis is disposed within the distal end of the proximal aortic stent-graft prosthesis to form an overlap between the proximal and distal aortic stent-graft prostheses. The overlap is relatively increased by the first branch stent-graft prosthesis proximally displacing the ostium of the brachiocephalic artery.
STENT GRAFT WITH A LONGITUDINAL SUPPORT MEMBER
A delivery system for delivering and deploying stent grafts having a proximal stent includes a first lumen and a stent capture device including a capture portion fixedly connected adjacent a first lumen distal end. An outer catheter has a catheter distal end and a catheter inner diameter. A second lumen having a second distal end is slidably disposed about the first lumen and within the outer catheter. A stent graft sheath has a sheath proximal end connected to the second distal end and disposed about the first lumen. The sheath has a sheath distal end and a sheath inner diameter greater than the catheter inner diameter for holding a compressed stent graft. A distal nose cone has a cone proximal end connected to either the capture portion or the first distal end. The nose cone and the capture portion are movably adjustable to selectively capture the sheath distal end therebetween.
DELIVERY GUIDE WIRE AND THERAPEUTIC DEVICE
A delivery guide wire (10,100) and a therapeutic device are disclosed. The therapeutic device includes the delivery guide wire (10, 100), a medical implant and a delivery catheter (20). The delivery guide wire (10, 100) includes a core shaft (110) and a driving member (120) disposed on the core shaft (110), and the driving member (120) defines thereon a depression. The medical implant is compressed by the delivery catheter (20) and disposed over the delivery guide wire (10,100) in such a manner that it is at least partially received in the depression. This results in an increased contact area between the medical implant and the delivery guide wire (10, 100), which facilitates movement of the medical implant in sync with the delivery guide wire (10, 100) and makes its delivery easier.
Orthopaedic implants and protheses
The present invention provides cervical implant (30) comprising an upper surface (38), a lower surface (40), a posterior portion (34) and an anterior portion (36) and including a perimeter (42) and one or more apertures (44,46) within said anterior portion for receiving securing means, said apertures having respective longitudinal axes M1, M2, characterised in that said axes extend in a direction substantially through said anterior portion (36) and converge at a point in a plane outside of said perimeter (42).
SUPPORT RING FOR VASCULAR AORTIC REPAIR AND METHODS OF USE
A stent graft and methods for treatment of aortic aneurysms includes a tubular graft component defining an inside surface, and outside surface, an open proximal end, an open distal end, and the fenestration. A proximal radial stent is proximal to the fenestration and a distal radial stent is distal to the fenestration. A ring at the tubular graft component extends along the tubular graft component and around the fenestration. A liner extends between the inside surface and the outside surface, and through the fenestration, the ring thereby being sealed from exposure at one surface of the tubular graft component by the liner, and at the other surface of the tubular graft component by the tubular graft component and the liner.
