    Abstract: Apparatus and methods are described including identifying a subject as suffering from a condition selected from the group consisting of: cardiac dysfunction, congestive heart failure, reduced renal blood flow, increased renal vascular resistance, arterial hypertension, and kidney dysfunction. In response thereto, blood pressure within a renal vein (32) of the subject is reduced, by placing a blood pump (150) inside the subject's renal vein and activating the impeller to pump blood from the renal vein into the subject's vena cava (26). Other applications are also described.

    Abstract: 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.

    Abstract translation: 描述了装置和方法，包括经由受试者的腹股沟的静脉将导管插入受试者的身体。 导管向远侧推进，使得导管的远端设置在受试者的肾静脉内。 导管的相应的稳定部分通过与受试者的髂内静脉的内壁和受试者的腔静脉接触来稳定导管。 随后，通过缩回导管的远端部分将医疗装置部署在肾静脉内部，使得导管的远端处于缩回状态，其中导管的各个稳定部分仍然通过进入导管来稳定导管 分别与受试者的髂内静脉和受试者的腔静脉的内壁接触。 还描述了其它应用。

    Abstract: Apparatus and methods are described including a blood pump that includes an axial shaft configured for insertion into, and rotation within, a subject's body. The blood pump also includes an impeller coupled to the axial shaft such that, as the axial shaft rotates, the impeller pumps blood of the subject. Proximal and distal radial bearings surround the axial shaft and are configured to radially stabilize the axial shaft while the axial shaft rotates. Proximal and distal sleeves, which are less flexible than the axial shaft, are disposed around the axial shaft, such that the proximal and distal sleeves contact the proximal and distal radial bearings, respectively, as the axial shaft rotates. A ratio between a length of the axial shaft and a combined length of the proximal sleeve and distal sleeve is between 2:1 and 6:1. Other applications are also described.
