In accordance with some configurations, systems and methods for guided removal from an in vivo subject are provided. In some configurations, a method for removing an object is provided. The method comprising, guiding a flexible tube through a passageway of an in vivo subject, wherein the flexible tube comprises at least a first passageway and a second passageway. Positioning a distal end of the first passageway in proximity to the object. Infusing liquid through the second passageway substantially continuously. Removing the object through the first passageway with at least a portion of the liquid while suction is not being provided.

A bursitis treatment device (100; 200) for treatment of inflammation of a bursa (150; 502) in a patient's joint includes: a rinsing aid; a reservoir (101; 201) for holding the rinsing aid in fluid, freezing fluid or gaseous state; a supply line (103; 204, 208) for transporting the rinsing aid; a heat exchanger (104; 203) for controlling the temperature of the rinsing aid—such that the temperature of the rinsing aid enables to destroy cells causing the inflammation; an access device (209) for injecting the rinsing aid into the bursa (150; 205); and a drain (105; 210) for removing the rinsing aid from the bursa (150; 205) for elimination.

An intraluminal system for aspirating biological material from a lumen of a patient includes a disposable intraluminal device having a proximal portion and a distal portion. The system includes a disposable pump configured to aspirate the biological material from the lumen of the patient. The disposable pump is coupled to the proximal portion of the intraluminal device. The disposable pump comprises a pump chassis that houses: an inlet port configured to sealably attach to the proximal portion of the intraluminal device; an outlet port configured to expel the aspirated biological from the pump; and a flow controller configured to adjust a fluid flow through the pump, wherein the pump chassis is sized and shaped to be manually supported by a user.

A surgical instrument for suction and irrigation, includes: an insertion tube inserted into the body of a patient; an instrument body coupled to the insertion tube and disposed outside the body of the patient; an irrigation fluid control valve coupled to the instrument body; and a drainage fluid control valve coupled to the instrument body and separated a predetermined distance from the irrigation fluid control valve in a longitudinal direction of the instrument body.

An apparatus, system and method for a handpiece for ocular surgical. Included may be at least: a proximal portion having at least inlet ports for irrigation tubing and aspiration tubing, and providing an irrigation fluidic pathway extending therethrough from the irrigation tubing inlet port, and an aspiration fluidic pathway extending therethrough from the aspiration inlet port; a distal portion terminating in an emulsifying tip, and providing an aspiration pathway terminating in an aspiration output, and at least one irrigation pathway terminating in at least one irrigation output; and a swivel ball provided at a base of the proximal portion and having a first opening to the irrigation fluidic pathway, and a second opening to the aspiration fluidic pathway, which seats within a socket cup provided at an upper end of the distal portion.

A system for treating internal bleeding via application of a heated irrigant, such that the heated irrigant is delivered at a flow rate of between 2 cc/s and 12 cc/s and at a temperature of between 46 degrees Celsius and 52 degrees Celsius.

Methods and apparatuses for automatically switching different aspiration levels to an ocular probe are disclosed herein. The probe may be a phacoemulsification probe. A first aspiration level, supplied by a first pump, may be applied to the probe simultaneously with ultrasonic energy. A second aspiration level, supplied by a second pump, may be automatically switched from the first aspiration level. Control feed back of the pumps may be varied according to set thresholds.

A minimally invasive system for monitoring and treating high intracranial pressure levels resulting from traumatic brain injury comprises an intravenous access device, an elongate member, a console, and an aspiration and injection catheter. The system is capable of monitoring pressure levels and relocating fluid from the brain to another part of the patient's body to sustain overall constant fluid volume. The method of using the minimally invasive system is also described.

The present disclosure generally relates to fluid control valves for delivering and/or aspirating fluid during ophthalmic surgeries and procedures. In one embodiment, a valve assembly includes a first portion configured to fluidly couple with a gas supply line and a second portion configured to fluidly couple with a liquid supply line and an infusion line. The first portion and the second portion are partitioned or separated from each other by a filter having a hydrophobic membrane configured to prevent the flow of liquids therethrough while allowing the free flow of gas. Accordingly, an infusion liquid may be flown through the second portion while gases may be simultaneously aspirated through the first portion, without any liquids travelling into the gas supply line. The gas supply line may thus be utilized to vent or purge gases from the infusion line before or during performance of surgical procedures.
