20090131743 | LOW FRICTION DELIVERY TOOL FOR A CARDIAC SUPPORT DEVICE - A delivery device for efficiently delivering a cardiac support device of the type having a jacket. The device includes a body, a deployment mechanism and an actuating mechanism. The deployment mechanism is for releasable connection to a cardiac support device and movable within the jacket between retracted and extended states to drive the jacket between collapsed and open configurations. At least portions of the deployment mechanism within the jacket have a lubricious surface to substantially reduce friction between the jacket and a heart onto which the jacket is being positioned. The actuating mechanism moves the deployment mechanism between the retracted and extended states. | 05-21-2009 |
20100185050 | COMPLIANT CARDIAC SUPPORT DEVICE - A jacket of biological compatible material has an internal volume dimensioned for an apex of the heart to be inserted into the volume and for the jacket to be slipped over the heart. The jacket has a longitudinal dimension between upper and lower ends sufficient for the jacket to surround a lower portion of the heart with the jacket surrounding a valvular annulus of the heart and further surrounding the lower portion to cover at least the ventricular lower extremities of the heart. The jacket is adapted to be secured to the heart with the jacket surrounding at least the valvular annulus and the ventricular lower extremities. The jacket is adjustable on the heart to snugly conform to an external geometry of the heart and assume a maximum adjusted volume for the jacket to constrain circumferential expansion of the heart beyond the maximum adjusted volume during diastole and to permit unimpeded contraction of the heart during systole. | 07-22-2010 |
20100249923 | COLLAPSIBLE/EXPANDABLE PROSTHETIC HEART VALVES WITH NATIVE CALCIFIED LEAFLET RETENTION FEATURES - A prosthetic heart valve is circumferentially collapsible for less invasive delivery into a patient. The valve re-expands to operating size at the implant site in the patient. A frame structure of the valve includes restraining structure that can help to push one or more of the patient's native heart valve leaflets radially outwardly so that this native leaflet tissue does not interfere with the operation or service life of the prosthetic valve. | 09-30-2010 |
20100274075 | CARDIAC SUPPORT DEVICE - A highly compliant and elastic cardiac support device is provided. The device is constructed from a biocompatible material is applied to an external surface of a heart. The device can be used to resist dilatation of the heart, to provide acute wall support, or to enhance reduction in the size of the heart using stored potential energy, without interfering with systolic contraction. | 10-28-2010 |
20100292780 | DEVICE FOR COMPRESSING A STENT AS WELL AS SYSTEM AND METHOD FOR LOADING A STENT INTO A MEDICAL DELIVERY SYSTEM - The invention relates to a device ( | 11-18-2010 |
20110166413 | COMPLIANT CARDIAC SUPPORT DEVICE - A jacket of biological compatible material has an internal volume dimensioned for an apex of the heart to be inserted into the volume and for the jacket to be slipped over the heart. The jacket has a longitudinal dimension between upper and lower ends sufficient for the jacket to surround a lower portion of the heart with the jacket surrounding a valvular annulus of the heart and further surrounding the lower portion to cover at least the ventricular lower extremities of the heart.

The jacket is adjustable on the heart to snugly conform to an external geometry of the heart and assume a maximum adjusted volume for the jacket to constrain circumferential expansion of the heart beyond the maximum adjusted volume during diastole and to permit unimpeded contraction of the heart during systole. | 07-07-2011 |
20110208290 | STENT FOR THE POSITIONING AND ANCHORING OF A VALVULAR PROSTHESIS IN AN IMPLANTATION SITE IN THE HEART OF A PATIENT - The present invention relates to a stent for the positioning and anchoring of a valvular prosthesis in an implantation site in the heart of a patient. Specifically, the present invention relates to an expandable stent for an endoprosthesis used in the treatment of a narrowing of a cardiac valve and/or a cardiac valve insufficiency. So as to ensure that no longitudinal displacement of a valvular prosthesis fastened to a stent will occur relative the stent in the implanted state of the stent, even given the peristaltic motion of the heart, the stent according to the invention comprises at least one fastening portion via which the valvular prosthesis is connectable to the stent. The stent further comprises positioning arches and retaining arches, whereby at least one positioning arch is connected to at least one retaining arch. | 08-25-2011 |
20110295363 | Prosthetic Heart Valve And Transcatheter Delivered Endoprosthesis Comprising A Prosthetic Heart Valve And A Stent - The invention relates to a prosthetic heart valve ( | 12-01-2011 |
20120071905 | METHOD AND APPARATUS FOR CREATING INTRAUTERINE ADHESIONS - In general, the present invention contemplates an implantable device for treating excessive bleeding in a body cavity. The device comprises a biocompatible material, for example polyethylene teraphathalate (PET), which is deliverable into the body cavity. The biocompatible material contains an attribute(s) that promotes tissue reaction or growth that results in a tissue response and/or adhesion formation within the body cavity to reduce or stop the excessive bleeding. | 03-22-2012 |
