A device for performing an ophthalmic procedure in an eye including a hand-held portion; an elongate member extending from a distal end region of the hand-held portion; and an aspiration pump within the hand-held portion. The elongate member includes a lumen and an opening near a distal end region of the elongate member. The aspiration pump is in fluid communication with the opening of the elongate member. The aspiration pump includes a camshaft extending along a longitudinal axis and having a plurality of lobed cams; tubing extending parallel to the longitudinal axis; and a plurality of cam followers driven by the cams of the camshaft to move in a plane perpendicular to the longitudinal axis to sequentially compress the tubing. Related devices, systems, methods are provided.

A pinch valve mechanism for use in a suction/irrigator device, wherein the device has a conduit for suction/irrigation. The pinch valve mechanism includes a first end having a first projection, a second end, operatively connected to the first end and a second projection. A spring means operatively connected to the second end, wherein the conduit is disposed between the first end and the second end such that the first projection and second projection are biased to pinch the conduit into a closed position. Compression of the spring means moves the first end away from the second end to move the conduit into an open position.

Nanoparticles are suspended in a fluid medium which is activated using an ultrasonic transducer in contact with the fluid medium. The fluid may be injected into a body cavity and ultrasonically activated to induce a cavitation effect. The body cavity may contain a natural or artificial hard surface, inflamed or with a biofilm harnessing bacteria, such as a bone, joint or implant, as well as the surrounding tissue. In an embodiment, a treatment device may be used before, during or after a procedure such as a minimally invasive or open surgery to disinfect the body cavity via irrigation with liquid containing suspended nanoparticles and ultrasonically activated. The irrigation device may supply the cavity with the liquid and include therein an ultrasonic transducer. The cleaning and disinfecting process may be performed as treatment of infection in absence of another surgical procedure.

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.

A phacoemulsification system includes a phacoemulsification probe with a distal end for insertion into an eye of a patient, an irrigation pump, an aspiration pump, and a processor. The probe includes an irrigation channel, an aspiration channel, an irrigation sensor, and an aspiration sensor. The irrigation pump is configured to flow irrigation fluid to the irrigation channel. The aspiration pump is configured to evacuate material from the aspiration channel. The processor is configured to detect a clogging of the aspiration channel using the aspiration sensor, to estimate an intra-ocular pressure (IOP) of the eye using the irrigation sensor, to set a reflux pressure for the aspiration pump depending on the estimated IOP, and to repel the clogging by controlling the aspiration pump to apply the reflux pressure.

A hand actuated suction and irrigation device enables the clinician to selectively provide suction or irrigation at a surgical site. In particular, the suction and irrigation device enables the clinician to control the amount of suction or irrigation provided at the surgical site through an ergonomically designed handle assembly. A clinician may selectively choose the suction or irrigation setting on the device by manipulating the first and second valve assemblies on opposing sides of a pump.

An assembly for nasal irrigation for the handheld irrigation of a user's nasal cavity comprising a housing with a refill chamber containing irrigating fluid, an applicator, an actuator for forcing irrigating fluid from the refill chamber through the applicator into the user's nasal cavity during operation, and a solution port for refilling the refill chamber. Some embodiments of the present invention may further comprise a system for nasal irrigation that includes the assembly for nasal irrigation or handheld irrigator, as well as a solution assembly structured for dispensing irrigating fluid to the handheld irrigator, a docking station for removably housing the handheld irrigator, a solution assembly and a refill control, including a check valve.

An actuator for synchronized injection and aspiration, comprising: a first rod, having a length equal to an inner length between a head of a first plunger of a first standard-size syringe and a seal of the first plunger, and having a width smaller than a gap created between the first plunger and a barrel of the first standard-size syringe; a second rod, having a length equal to an inner length between a head of a second plunger of a second standard-size syringe and a seal of the second plunger, and having a width smaller than a gap created between the second plunger and a barrel of the second standard-size syringe; a flexible connector mechanically attached to a distal end of the first rod at a first end and to a distal end of the second rod at a second end.

A cassette and remote control assembly includes a cassette, a remote control attachment, and an electrical connector. The cassette includes a fluid line coupled between a fluid input and a fluid output and is configured to couple to a console to enable pumping of fluid along the fluid line. The cassette also includes an electronics board configured to communicate with the console. The remote control attachment is configured to releasably attach to a handpiece of a surgical device and includes at least one sensor configured to sense at least one property of the handpiece, a user input interface configured to receive a clinician input, and/or an output device configured to output an indicator. The electrical connector connects the remote control attachment with the cassette, thereby electrically coupling the electronics board of the cassette with the sensor, the user input interface, and/or the output device of the remote control attachment.

A tissue cutting device is disclosed and described. The device includes a handpiece and an outer cannula in which a reciprocating inner cannula is disposed. A delivery sleeve may be selectively provided that is configured to be disposed about the outer cannula for delivery of a variety of devices.
