A prosthetic heart valve can include a valve frame having a wireform portion and a stent portion. The wireform and stent portions can be undetachably coupled together via a plurality of upright struts so as to form a one-piece prosthetic heart valve frame. Alternatively, a self-expanding wireform portion and a balloon-expandable stent portion can be coupled together via one or more leaflets and a subassembly having a flexible leaflet support stent and a sealing ring. The wireform portion can include cusps and commissures configured to support a plurality of leaflets. The prosthetic valve can be radially collapsible for minimally invasive and/or transcatheter delivery techniques. Disclosed embodiments can also provide flexion of the wireform portion (e.g., of the commissures) in response to physiologic pulsatile loading when the valve is implanted in a patient's native valve annulus. Methods of making and using prosthetic heart valves are also disclosed.

Принадлежит: Boston Scientific Scimed Inc

A temporary stent endoprosthesis that does not require an interventional procedure for removal. The disintegrating stent is preferably made from a bioabsorbable polymer, such as by braiding polymer monofilaments into a tubular mesh shape, and the polymer has fracture initiation sites within it that promotes the disintegration of the stent into small pieces that are harmlessly transported out of the body by the vessel contents. Fracture initiation sites may be created by controlling the heterogenous structure of amorphous and crystalline regions, by introducing internal or surface fracture initiation sites, or use of multiple strands with small section size.

A medical device including a mesh prosthesis having a first layer having an opening a second layer secured to the first layer and forming a pocket therebetween. A deployment device is positioned in the pocket and arranged to resiliently exert a deployment force on the mesh prosthesis to urge the mesh prosthesis into a deployment shape. The deployment device has a first shape when deployed that has at least one dimension larger than that of the opening to frustrate removal of the deployment device therethrough. Upon application of a suitable pulling force the deployment device is reconfigurable into a second shape that permits the deployment device to be removed from the pocket through the opening upon application of the suitable pulling force. A method of using a medical device is also included.

It is estimated by the U.S. National Center for Health Statistics that 247,000 operations for genital prolapse were performed in 1998. With the increasing age of the U.S. population, these problems will likely assume additional importance.The common clinical symptoms of vaginal prolapse are related to the fact that, following hysterectomy, the vagina is inappropriately serving the role of a structural layer between intra-abdominal pressure and atmospheric pressure. This pressure differential puts tension on the supporting structures of the vagina, causing a “dragging feeling” where the tissues connect to the pelvic wall or a sacral backache due to traction on the uterosacral ligaments. Exposure of the moist vaginal walls leads to a feeling of perineal wetness and can lead to ulceration of the exposed vaginal wall. Vaginal prolapse may also result in loss of ...

Принадлежит: Medtronic Vascular Inc

The techniques of this disclosure generally relate to a prosthesis including framed biodegradable yarn graft material having a frame and biodegradable yarns combined with the frame. The biodegradable yarns seal tissue integration openings within the frame. The frame provides long term mechanical strength while the biodegradable yarns provide acute strength and impermeability to prevent endoleaks. As the biodegradable yarns degrade, the drop in textile density creates tissue integration openings, through which tissue grows. The integrate of tissue into the framed biodegradable yarn graft material provides biological fixation of the prosthesis in vessels and prevents endoleaks and migration of the prosthesis.

The techniques of this disclosure generally relate to a variable permeability layered prosthesis including an impermeable outer layer and a permeable inner layer. The impermeable outer layer is well suited to seal a dissection opening of a dissection. The permeable inner layer allows fluid to enter into a dead space between the impermeable outer layer and the permeable inner layer. The fluid in the dead space coagulates in the dead space providing a media for tissue growth into the prosthesis. The ability of tissue to integrate into the prosthesis provides biological fixation of the prosthesis in vessels and prevents endoleaks and migration of the prosthesis.
