Abstract
Official abstract text for this publication.
Apparatus and methods are described including inserting a catheter into a subject's body via a vein of the subject's groin. The catheter is advanced distally such that a distal end of the catheter is disposed inside the subject's renal vein. Respective stabilizing portions of the catheter stabilize the catheter by being in contact with inner walls of, respectively, an iliac vein of the subject, and a vena cava of the subject. Subsequently, a medical device is deployed inside the renal vein by retracting the distal end of the catheter, such that the distal end of the catheter is in a retracted state, in which the respective stabilizing portions of the catheter still stabilize the catheter by being in contact with the inner walls of, respectively, the subject's iliac vein and the subject's vena cava. Other applications are also described.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method comprising: inserting a catheter into a body of a subject via an artery of a groin of the subject, and advancing the catheter distally such that: a distal end of the catheter is disposed inside a renal artery of the subject, and respective stabilizing portions of the catheter stabilize the catheter by being in contact with inner walls of, respectively, an iliac artery of the subject, and an aorta of the subject; and subsequently, deploying a medical device inside the renal artery by retracting the distal end of the catheter, such that the distal end of the catheter is in a retracted state, in which the respective stabilizing portions of the catheter still stabilize the catheter by being in contact with the inner walls of, respectively, the subject's iliac artery and the subject's aorta. 2. The method according to claim 1 , wherein advancing the catheter distally comprises advancing the catheter distally such that a further stabilizing portion of the catheter stabilizes the catheter by being in contact with an inner wall of the renal artery. 3. The method according to claim 1 , wherein retracting the distal end of the catheter comprises retracting the distal end of the catheter, such that while the distal end of the catheter is in its retracted state, a further stabilizing portion of the catheter stabilizes the catheter by being in contact with an inner wall of the renal artery. 4. The method according to claim 1 , wherein advancing the catheter distally such that the distal end of the catheter is disposed inside the subject's renal artery comprises advancing the catheter distally such that the distal end of the catheter is disposed inside a renal artery of the subject that is contralateral to the artery of the subject's groin via which the catheter is inserted. 5. The method according to claim 1 , wherein advancing the catheter distally such that the distal end of the catheter is disposed inside the subject's renal artery comprises advancing the catheter distally such that the distal end of the catheter is disposed inside a renal artery of the subject that is ipsilateral to the artery of the subject's groin via which the catheter is inserted. 6. The method according to claim 1 , further comprising operating the medical device, inside the renal artery, while the catheter is disposed inside a body of the subject in its retracted state, such that the catheter supports the medical device during its operation. 7. The method according to claim 6 , wherein deploying the device comprises deploying a radially-expandable impeller that is disposed inside a radially-expandable impeller cage, and wherein operating the medical device comprises rotating the impeller.
