Abstract: An apparatus for guiding the migration of cancer and other cells includes a reservoir device, a cover, a tube, a nanofiber structure, and a lock device. The reservoir device defines a reservoir having an open top. The cover is configured for removable installation over the open top of the reservoir. The tube has a proximal end portion reaching into the reservoir. The nanofiber structure communicates an inlet port in the tube with the reservoir. The lock device interlocks the tube with the reservoir device, and also interlocks the nanofiber structure with the reservoir device.

Abstract: The cardiovascular device (1) comprises a diaphragm assembly designed to be inserted into a ventricular cavity (VS) substantially transverse in order to reduce its volume, said diaphragm assembly having a peripheral edge (2B) that can be sealingly engaged on the walls (5) of the cavity 7 and being alternately driven between an active blood thrust position and an inactive position, said assembly being at least partially deformable in response to contractions of the walls (5) and comprising a balloon-shaped elastic body (2; 100; 200; 300; 400) which has an external surface (2A; 103) that defines and encloses an internal cavity (CI; CI2) and which can be configured between a gathered position of minimum bulk, an everted position of maximum bulk and vice-versa, at least one mobile portion (3; 3?) of the peripheral surface which is disposed transverse/diagonal and which is surrounded by the peripheral edge and at least one aperture (3A) for access from the outside to the internal cavity (CI; CI2).
