Abstract

A device for exploration of the cardiovascular system of human or animal bodies includes a generally transparent blind tube delimiting a cavity in which can be disposed an optical display device, the open end of the tube being shaped to be ensleeved axially in a sealed manner in the passage of an artery or of a vein having first been at least partially sectioned such that the cavity of the tube in the interior of the artery or of the vein form a common chamber at least partially closeable by a cardiac valve. The tube, maintained in ensleeved position by a suitable securement member, includes at least one supplemental opening for the introduction into the cavity of the tube of a physiological liquid under pressure.

Claims

1. A device for the per-operative exploration of an organ of a cardiovascular system of a human or animal body, comprising:

a hollow body made of a sealed material, said hollow body defining a cavity for an optical display device,

said cavity being open into and/or into the vicinity of an open end of the hollow body, the open end of the hollow body being introduced through an opening of an organ to be explored and being shaped to directly or by means of at least one suitable securement member to connect in a substantially sealed manner the hollow body to the organ such that the cavity of the hollow body and an interior of the organ to be explored form a common chamber at least partially closeable by a closure member present in the organ to be explored,

the hollow body comprising, opposite the open end of the hollow body, at least one supplemental opening that opens into said cavity for the introduction into said cavity of a liquid under pressure to increase a pressure prevailing within the organ so as to facilitate the exploration.

2. The exploration device according to claim 1,

wherein the hollow body comprises, over its periphery, in its region of connection to the organ to be explored, at least one continuous or discontinuous external circumferential swelling and/or recess to form respectively at least one enlarged or recessed portion, which enlargement and/or recess coacts with the securement member to ensure a sealed ensleeving of the hollow body in the organ to be explored.

3. The device according to claim 1,

wherein the securement member presses on at least a portion of walls of the organ to be explored against sidewalls of the hollow body.

4. The exploration device according to claim 3,

wherein the securement member is shaped as an elastically deformable open ring or a belt.

5. The exploration device according to claim 1,

wherein the hollow body comprises, at its periphery, a ring slidably mounted on the hollow body the ring being applied against an external periphery of an opening in a ventricle and ensuring, in coaction with a ventricle wall, a substantially sealed connection between the hollow body and the ventricle.

6. The exploration device according to claim 1,

wherein the hollow body comprises a further supplemental opening whose edges are secured to a pocket at least partially transparent and shaped to be able to be disposed within the cavity, this at least partially transparent pocket serving for the reception of the optical display device, and isolating said display device from other contents of said cavity.

7. The exploration device according to claim 1,

wherein the optical display device comprises a camera orientable by means of an arm projecting outside said body.

8. The exploration device according to claim 1,

wherein said body comprises at least two of said supplemental opening, at least one of the supplemental openings being provided on a lateral wall of the body, said supplemental openings comprising closure members.

9. The exploration device according to claim 1,

further comprising means for measuring the pressure prevailing within said common chamber to determine a quantity of liquid to be introduced into said chamber.

10. The exploration device according to claim 1,

wherein the hollow body comprises at least one elbow.

11. A device for per-operative exploration of an organ of a human or animal body, the device comprising:

a hollow body defining a cavity, an open end of said cavity being adapted to be placed, using a connection device, into an opening of an organ to be explored so that an interior of the organ and the cavity form a common chamber,

the connection device including a securement member placed so as to connect the hollow body and the organ in a substantially sealed manner,

the hollow body comprising at least one supplemental opening opposite to the open end for introducing a liquid under pressure into an interior of the organ to be explored so as to facilitate exploration of the organ.
