A surgical extractor for removing objects from a body including, for example, calculi, such as kidney stones and gall stones. The extractor includes a handle at an proximal end of the extractor with a slider for operation by a physician. At the distal end the extractor includes a plurality of wires with each wire comprising a first portion having an individual strand and a second portion comprising a plurality of filaments. When a retaining sheath is retracted, the wires, formed of a shape memory material such as stainless steel, expand such that each of strands assume a spaced relationship to define a first section of a basket and the plurality of the filaments assume a spaced relationship to define a second section of the basket. The use of a basket formed by wires having a first section comprising an individual strand and a second section comprising the plurality of filaments promotes capture of objects within the body by having widely spaced wires in the first section, retention of such objects in the second section by multiplying the number of contacts with entrapped object, and improved selective release of such objects without any deleterious effect on the reliability or size of the extractor. Additionally, use of the basket enables improved dislodgment and capture of embedded or impacted objects.

An electrosurgical system and method for treating hard and soft tissues in the body comprises a shaft, a distal end section, an active electrode associated with the distal end section, a first fluid supply adapted to deliver a first electrically conductive fluid to the target site, and a second fluid supply adapted to deliver a second electrically conductive fluid to the active electrode. The system is adapted to treat a wide variety of hard tissues such as, for example, bones, calcified structures, calcified deposits, teeth, plaque, kidney-stones, gall-stones and other types of tissue by generating plasma in the vicinity of the active electrode, and applying the plasma to the tissue or structures.

Methods and devices for at least reducing the mass of, if not dissolving, renal calculi in situ are provided. In the subject methods, a renal calculus is contacted, e.g. flushed, with an acidic dissolution solution in situ, where the acidic dissolution solution is a solution of a strong, inorganic acid, e.g. hydrochloric acid. In many embodiments, the renal calculus is first enclosed in an isolated local environment of a device prior contact with the dissolution solution. Also provided are novel devices and kits for practicing the subject invention.

The present invention improves significantly the success rate of lithotripsy and reduces the risk of tissue damage, by injecting temporary plugs in front and behind a concretion (for extracorporeal lithotripsy) or behind a concretion (for intracorporeal lithotripsy). One aspect of the present invention relates to injecting an inverse thermosensitive polymer solution into a lumen, thereby preventing the migration of a concretion, or its fragments, upon extracorporeal or intracorporeal lithotripsy.

Occluding structures may be created within a body lumen by advancing a length of material distally through the body lumen. By drawing a distal location on the advanced length of material in a proximal direction, the material may be compacted into a structure which at least partially occludes the lumen. The occluding structure may be used to remove kidney stones from the ureter in conjunction with lithotripsy and irrigation.

A rigid extractor is revealed, a rigid device for use in percutaneous procedures to remove kidney stones directly from the kidneys. The rigid extractor uses a handle fixed to an outer rigid cannula, and an inner cannula to control an extraction device that may be removable from the inner cannula. The extractor is desirably used with a fluoroscope, in which the surgeon maneuvers the extractor with the aid of a view of the operating field provided by the fluoroscope. The surgeon then maneuvers the extractor to grasp the kidney stones and remove from the patient. The extractor may also be used with a nephroscope. The device may be used with a removable extraction device such as a basket, a grasper a pair of jaws, or a pair of scissors.

The invention discloses a novel traditional Chinese medicine composition for treating the symptoms of renal calculus and a preparation method thereof. The traditional Chinese medicine composition mainly comprises the following raw materials of medicines: scaly anteater, rhizoma sparganii, rhizoma zedoariae, sweetgum fruit, immature bitter orange, Chinese eaglewood, dalbergia wood, tangerine peel, TurmericRoot-tuber, chicken's gizzard-membrane, radix notoginseng, rhizoma ligustici wallichii, red peony root, peach kernel, safflower, logwood, mastic, myrrh, draconis sanguis, Chinese polyphaga, rhizoma cyperi, tuckahoe, radix puerariae, rhizoma alismatis, manchurian dutchmanspipe, japanese fern spore, semen lepidii, talcum, rosa banksiae, green tangerine peel, toosendan fruit, areca peel, dahurian angelica root, rhizoma atractylodis, schisandra fruit and motherwort. The traditional Chinese medicine composition can be prepared into any common oral preparation according to a conventional traditional Chinese medicine preparation method. The invention can obviously improve the symptoms of the metabolic balance maladjustment of colloids and crystals, infection, nutrition metabolic disturbance, the calculus and the urine stasis of the urinary system, lumbago, renal colic, bloody urine and the like in the body of a patient with the symptoms of the renal calculus, can improve the symptoms of gout, diabetes, hypertension, acute pyelonephritis, chronic renal failure, uremia and the like caused by the symptoms of the renal calculus and has definite clinical curative effect, obvious curative effect and quick acting. Because of basically adopting medicine-food homologous medicines specified by the dispensatory of China for combination, the traditional Chinese medicine composition has the advantages of low cost, no toxic or side effect basically and the like.

The present invention improves significantly the success rate of lithotripsy and reduces the risk of tissue damage, by injecting a temporary plug in front, and optionally behind a concretion (for extracorporeal lithotripsy) or behind a concretion (for intracorporeal lithotripsy). One aspect of the present invention relates to injecting an inverse thermosensitive polymer solution into a lumen, thereby preventing the migration of a concretion, or its fragments, upon extracorporeal or intracorporeal lithotripsy.
