Cardiovascular device and kit for the reduction of a cardiac cavity

Kit for dividing a cardiac cavity (VS), characterized in that it comprises:

• a cardiovascular device (1) which has a balloon-shaped elastic body (2;
• 100, 200;
• 300, 400) which has an external surface (2A;
• 103) which defines and encloses an internal chamber (CI) and which is mobile alternately between a folded position of minimum bulk and an everted position of maximum bulk, and vice-versa;
• at least one mobile portion (3;
• 3′) of said external surface (2A;
• 103) which is transverse/diagonal with respect to said greater longitudinal dimension and which is peripherally surrounded by a peripheral edge (2B);
• at least one aperture (3A) for access from the outside to said internal chamber (CI);
• a catheter (9) which has a housing tip (15) for internally receiving said cardiovascular device (1) in a folded configuration for introduction into a cardiac cavity (VS) and a plunger (17) for expelling said cardiovascular device (1) from said housing tip (15);
• a syringe (8) for injecting a volume of fluid into said internal chamber (CI).

A balloon-shaped elastic body (2;

• 100, 200;
• 300;
• 400) intended for a cardiovascular device (1) able to be implanted in a cardiac cavity (VS) which has a volume and wherein blood flows, which is bounded by walls (5) and which has a greater longitudinal dimension and a smaller transverse dimension, said elastic body having an external surface (103) which defines and encloses an internal chamber (CI, CI2) and which is modifiable alternatively between a position of minimum bulk in said inactive position and an everted position of maximum bulk in said active position, and vice-versa, characterized in that said balloon-shaped elastic body comprises an internal core (101) which passes through said internal chamber (CI, CI2) in a hermetically sealed manner and extends between a distal end and an apical end and which has an axial length able to be modified elastically with modification means between a dilated position of said external surface (2A;
• 103) and a contracted position of said external surface (2A;
• 103).
