摘要： Disclosed herein are medical devices comprising a single-lobed, thin-walled, expandable body and a flexible, elongated delivery device for treating saccular vascular aneurysms and occluding segments of blood vessels and other biological conduits. The expandable bodies may include gold and other metals that can be compressed, positioned in the lumen of an aneurysm, or other biological conduit and expanded. The external surface of the expandable bodies can be configured to promote local thrombosis and to promote the growth of tissue into and around the surface in order to reduce migration of the expandable body and to occlude and seal the aneurysm or biological conduit. For the treatment of saccular aneurysms, the expandable body may be deployed in combination with one or more coiled wires that contact both the wall of the aneurysm and the expandable body and exert force on the expandable body to aid in sealing the aneurysm neck.

摘要： Disclosed herein are medical devices comprising a single-lobed, thin-walled, expandable body (“ballstent” or “blockstent”) and a flexible, elongated delivery device (“delivery catheter”) and systems and methods of use for treating saccular vascular aneurysms and methods of use for occluding segments of blood vessels and other biological conduits.
Expandable bodies comprising gold, platinum, or silver that can be compressed, positioned in the lumen of an aneurysm or blood vessel, and expanded to conform to the shape of the aneurysm or segment of blood vessel or biological conduit are disclosed. The external surface of the expandable bodies can be configured to promote local thrombosis and to promote the growth of tissue into and around the wall in order to reduce migration of the expandable body and to occlude and seal the aneurysm or biological conduit. The wall of the expandable bodies can also be configured to release drugs or pharmacologically active molecules, such as those that promote thrombosis, cell proliferation, extracellular matrix deposition, or tissue ingrowth.

摘要： Disclosed herein are devices, designs, methods of manufacturing and using medical devices comprising expandable bodies for treating saccular vascular aneurysms and occluding segments of blood vessels and other biological conduits. Exemplary expandable bodies include hollow gold structures that can be folded, wrapped, and compressed, joined to a delivery device, advanced to location in the body of patient in need of treatment, expanded by injection of a fluid into the central void, and separated from the delivery device, remaining in place in an open, expanded form without the addition of support structures to the central void. Other expandable bodies include coiled wires that can be loaded into delivery catheters and expelled from the delivery catheters using pusher devices. Also disclosed herein, are methods of using multiple medical devices and expandable bodies where the expandable bodies are placed adjacent to each other to occlude a saccular aneurysm.
