摘要
Disclosed herein are systems, devices, and methods for the removal of objects from the body. The device may be a urethral catheter configured to aspirate kidney stones from the urinary tract through one or more aspiration ports at the distal face or along a lateral side of the catheter. The catheter may include one or more irrigation ports at the distal face or along the lateral side of the catheter for dislodging kidney stones. The device may be steerable. The spatial arrangement of the one or more irrigation ports with respect to the one or more aspiration ports may vary. The device may include an irrigation tube and/or a shield member configured to spatially confine the kidney stones adjacent the catheter. Various temporal patterns of aspiration and irrigation are disclosed for optimizing removal of kidney stones.
