The tool includes a sheath, and an atraumatic tip, which is removably engaged to a distal end of the sheath, and which is shaped so as to define a body that defines a recess for housing the tissue anchor during guiding of the tool through vasculature of a patient. ## Claims ### Claim at position 1 1-96. (canceled) ### Claim 97 Apparatus for use with a guidewire, the apparatus comprising: a tissue anchor; and a tool for facilitating implanting of the tissue anchor, the tool comprising: a sheath; and an atraumatic tip, which is removably engaged to a distal end of the sheath, and which is shaped so as to define a body that defines a recess for housing the tissue anchor during guiding of the tool through vasculature of a patient. ### Claim 98 (depends on 97) The apparatus according to claim 97, wherein the atraumatic tip and the body are rotationally asymmetrical. ### Claim 99 (depends on 98) The apparatus according to claim 98, wherein the recess is radially off-center in the rotationally asymmetrical atraumatic tip. ### Claim 100 (depends on 98) The apparatus according to claim 98, wherein the rotationally asymmetrical atraumatic tip is shaped so as to define a lumen, through which the guidewire passes. ### Claim 101 (depends on 100) The apparatus according to claim 100, wherein the lumen is radially off-center in the rotationally asymmetrical atraumatic tip. ### Claim 102 (depends on 100) The apparatus according to claim 100, wherein the tool further comprises a guidewire tube, which passes through the sheath and the lumen of the atraumatic tip, and is configured to hold the guidewire. ### Claim 103 (depends on 102) The apparatus according to claim 102, wherein the rotationally asymmetrical atraumatic tip, the sheath, and the guidewire tube are arranged such that distal advancement of the guidewire tube disengages the rotationally asymmetrical atraumatic tip from the distal end of the sheath. ### Claim 104 (depends on 103) The apparatus according to claim 103, wherein the tool further comprises a torque-delivering cable, which is disposed within the sheath, and which is removably coupled to a proximal end of the tissue anchor, and wherein the rotationally asymmetrical atraumatic tip, the torque-delivering cable, and the tissue anchor are arranged such that proximal withdrawal of the torque-delivering cable retracts the tissue anchor from the recess of the rotationally asymmetrical atraumatic tip. ### Claim 105 (depends on 97) The apparatus according to claim 97, wherein the tool further comprises a torque-delivering cable, which is disposed within the sheath, and which is removably coupled to a proximal end of the tissue anchor, and wherein the atraumatic tip, the torque-delivering cable, and the tissue anchor are arranged such that proximal withdrawal of the torque-delivering cable retracts the tissue anchor from the recess of the atraumatic tip. ### Claim 106 (depends on 97) The apparatus according to claim 97, wherein the tissue anchor is helical. ### Claim 107 A method comprising: advancing a guidewire through vasculature of a patient; guiding, along the guidewire to an implantation site, a tool for facilitating implanting of a tissue anchor, the tool including a sheath and an atraumatic tip, which is removably engaged to a distal end of the sheath, and which is shaped so as to define a body that defines a recess for housing the tissue anchor during the guiding of the tool through vasculature of a patient; releasing the tissue anchor from the recess of the atraumatic tip; and implanting the tissue anchor in tissue of the patient. ### Claim 108 (depends on 107) The method according to claim 107, wherein the atraumatic tip and the body are rotationally asymmetrical. ### Claim 109 (depends on 108) The method according to claim 108, wherein the recess is radially off-center in the rotationally asymmetrical atraumatic tip. ### Claim 110 (depends on 108) The method according to claim 108, wherein the rotationally asymmetrical atraumatic tip is shaped so as to define a lumen, through which the guidewire passes. ### Claim 111 (depends on 110) The method according to claim 110, wherein the lumen is radially off-center in the rotationally asymmetrical atraumatic tip. ### Claim 112 (depends on 110) The method according to claim 110, wherein the tool further includes a guidewire tube, which passes through the sheath and the lumen of the atraumatic tip, and is configured to hold the guidewire. ### Claim 113 (depends on 112) The method according to claim 112, wherein releasing the tissue anchor from the recess of the rotationally asymmetrical atraumatic tip comprises disengaging the rotationally asymmetrical atraumatic tip from the distal end of the sheath by pushing on the guidewire tube. ### Claim 114 (depends on 113) The method according to claim 113, wherein the tool further includes a torque-delivering cable, which is disposed within the sheath, and which is removably coupled to a proximal end of the tissue anchor, wherein implanting the tissue anchor comprises rotating the torque-delivery cable, and wherein releasing the tissue anchor from the recess of the rotationally asymmetrical atraumatic tip comprises retracting the tissue anchor from the recess of the rotationally asymmetrical atraumatic tip by pulling proximally on the torque-delivering cable. ### Claim 115 (depends on 107) The method according to claim 107, wherein the tool further comprises a torque-delivering cable, which is disposed within the sheath, and which is removably coupled to a proximal end of the tissue anchor, wherein implanting the tissue anchor comprises rotating the torque-delivery cable, and wherein releasing the tissue anchor from the recess of the atraumatic tip comprises retracting the tissue anchor from the recess of the atraumatic tip by pulling proximally on the torque-delivering cable. ### Claim 116 (depends on 107) The method according to claim 107, wherein the tissue anchor is helical.
