Abstract

The invention discloses an artificial valve (10, 20) for implantation in a mammal aorta or heart as an auxiliary aortic valve in addition to an aortic valve. The artificial valve (10, 20) comprises at least a first (12,17) moving part adapted to be able to move to assume an open and a closed position for opening and closing, respectively, of the blood flow through a blood vessel. The artificial valve (10, 20) also comprises a casing (14, 24), and said at least one first (12, 17) moving part is movably attached to said casing (14, 24). The artificial valve (10, 20) is adapted to let the at least one moving part initiate its movement to the open position at a level of blood pressure on a blood supplying side of the valve which is at least 5 mm Hg higher than the mammal'"'"'s diastolic aortic blood pressure on the other side of the valve.

Claims

1-132. -132. (canceled)

133. A method of surgically placing an auxiliary artificial valve in a blood vessel of a patient, the method comprising the steps of:

making an incision in the skin of the patient,

introducing the auxiliary artificial valve into the body of the patient, and

placing the auxiliary artificial valve in the aorta between the exit to the coronary arteries and the exit to the carotid arteries.

134. The method according to claim 133, wherein the method is a vascular approach, and wherein the method comprises the steps of making an incision in a blood vessel of the patient and introducing the valve in the blood vessel.

135. The method according to claim 133, wherein the method is an inguinal vascular approach.

136. The method according to claim 133, wherein the method is a thoracic approach.

137. The method according to claim 136, wherein the thoracic approach comprises at least one of the steps of:

opening the thoracic cavity,

dissecting a placement area of the aorta,

introducing the auxiliary artificial valve into the thorax of the patient, and

placing the valve in the placement area.

138. The method according to claim 136, wherein the method is a thoracic laparoscopic approach.

139. The method according to claim 138, wherein the thoracic laparoscopic approach comprises at least one of the steps of:

inserting a needle or a tube like instrument into the thorax of the patient'"'"'s body,

using the needle or a tube like instrument to fill the thorax with gas thereby expanding the thoracic cavity,

inserting a at least one laparoscopic trocar,

inserting a camera through the laparoscopic trocar into the thorax,

inserting at least one dissecting tool through at least one laparoscopic trocar and dissecting a placement area,

placing the valve in the placement area using laparoscopic tools.

140. The method according to claim 133, wherein the method is an abdominal approach.

141. The method according to claim 140, wherein the abdominal approach comprises at least one of the steps of:

opening the abdomen of the patient,

making an incision in the diaphragm of the patient, for reaching the thorax of the patient,

dissecting a placement area of the aorta,

introducing the auxiliary artificial valve into the abdomen of the patient,

introducing the auxiliary artificial valve into the thorax of the patient, and

placing the valve in the placement area.

142. The method according to claim 140, wherein the method is an abdominal laparoscopic approach.

143. The method according to claim 142, wherein the abdominal laparoscopic approach comprises at least one of the steps of:

inserting a needle or a tube like instrument into the abdomen of the patient,

using the needle or a tube like instrument to fill the abdomen with gas thereby expanding the abdominal cavity,

inserting a at least one laparoscopic trocar,

inserting a camera through the laparoscopic trocar, into the abdomen,

inserting at least one dissecting tool through at least one laparoscopic trocar,

making an incision in the diaphragm of the patient, for reaching the thorax of the patient,

dissecting a placement area of the aorta,

introducing the auxiliary artificial valve into the abdomen of the patient,

introducing the auxiliary artificial valve into the thorax of the patient, and

placing the valve in the placement area using laparoscopic tools.

144. The method according to claim 133, wherein the method further comprises implanting a source of energy for powering the auxiliary artificial valve.

145. The method according to claim 133, wherein the method further comprises implanting a wireless energy receiver for receiving wireless energy after said wireless energy receiver has been implanted.

146. The method according to claim 133, wherein the method further comprises implanting at least one pressure sensor for sensing the blood pressure on at least one side of the auxiliary artificial valve.

147. The method according to claim 133, wherein the method further comprises implanting at least one control unit for controlling the opening and closing of said auxiliary artificial valve.

148. The method according to claim 133, wherein the method further comprises placing a drive unit for at least partly powering the auxiliary artificial valve, on the outside of the blood vessel.

149. The method according to claim 133, wherein the method further comprises implanting at least one sensor for sensing the electrical pulses or muscle contractions of the heart.

150. The method according to claim 145, wherein the step of implanting a wireless energy receiver comprises implanting the wireless energy receiver in the abdomen.

151. The method according to claim 133, wherein the method further comprises implanting an internal wireless signal transceiver for communicating with an external wireless signal transceiver located outside of the patients body.

152. The method according to claim 133, wherein the method further comprises operating the auxiliary artificial valve to move an open position at a level of blood pressure on a blood supplying side of the auxiliary artificial valve which is at least 5 mm Hg higher than the diastolic aortic blood pressure of the patient on the other side of the valve.
