Abstract: A vascular pulsation device may be provided including a pulsation portion and a reservoir portion. The pulsation portion may be insertable into a bodily passageway and may include an expandable segment, a first end, and a second end. The reservoir portion may be in fluid connection with the pulsation portion by a supply passage and a return passage. An opening of the supply passage may be positioned proximate to the second end of the pulsation portion. An opening of the return passage may be positioned proximate to the first end of the pulsation portion.

Abstract: A wireless medical device release system may reduce the overall diameter of the medical device delivery system. The medical device delivery system may include a medical device with a looped portion at a section of the medical device. A capture element may be located on a delivery tool that is distal to the medical device. The looped portion of the medical device may be located in the capture element and held in the capture element by a sheath covering the delivery tool. Removal of the sheath may release the looped portion of the medical device from the capture element and delivery tool.

Abstract: A stent graft device that requires an anchor setting procedure to prevent migration of the stent, such as an endovascular anchor stent device used for treatment of an abdominal aortic aneurism, can be anchored to a blood vessel by electrosurgically disrupting portions of the blood vessel in situ to affix struts of the stent graft device to the vessel wall, replacing barbs which have been used in such devices. The stent graft device can have a wire frame and struts or a cannula stent frame body with struts cut from the cannula. The struts can be provided with openings which are filled with extracellular matrix material, which encourages and speeds ingrowth of the struts in the vessel wall.
