An extension conduit for use with a system for aspirating thrombus includes a passageway extending between a distal end and a proximal end of the extension conduit, and a combined hydraulic and electrical control carried on the extension conduit and configured to be activated by a user to activate an electric switch while opening a valve to allow flow through the passageway.

Medical/surgical lavage unit with a pump that includes a bellows chamber and a supplemental chamber
11419973 · 2022-08-23 · ·

A lavage unit may include a handpiece configured to house a pump to which an irrigation tube is connected. The pump may include a bellows defining a pump chamber. When the bellows is reciprocated by a linkage, the bellows draws irrigation fluid from the irrigation tube into the pump chamber and then discharges the fluid out of the pump chamber through an outlet. The pump further includes a section formed from compressible or flexible material that defines a supplemental chamber. The linkage is connected to said pump to alternatively compress the bellows forming the pump chamber and the material forming the supplemental chamber. During the movement of the linkage a valve located between the pump chamber and the supplemental chamber reciprocates with the linkage.

NASAL IRRIGATION ASSEMBLY AND SYSTEM
20220313966 · 2022-10-06 ·

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.

Systems and methods for measuring fluid flow in a venturi based system

Variables of a surgical system are detected or received via one or more sensors to predict an intraocular pressure (IOP) and/or determine an IOP in real time during a surgical procedure. A notification to a surgeon or a target IOP is set and maintained as determined by Static IOP, dynamic IOP, and/or a total IOP combining both static and dynamic IOP of the anterior chamber of a patient's eye. Information collected about various components of the system are displayed on a user interface. The system uses the collected information to calculate the static IOP and/or dynamic IOP of the system, and the total IOP may be function of the static IOP and/or dynamic IOP measurements.

Ocular surgical work tip adapter
11419971 · 2022-08-23 · ·

An adapter for a surgical hand piece with a single lumen work tip converts the handpiece to infusion/aspiration (I/A) cleanup of lens epithelial cells in the capsular bag of the eye a patient after phacoemulsification. The adapter is in the form of a sleeve whose proximal end is to be joined to the distal end of work tip. The sleeve also has at least one aspiration hole located toward the distal end of the sleeve.

Wireless electronic pump design for a body cavity irrigation device

A trans-anal irrigation (TAI) device has a pump base unit, an irrigation fluid reservoir, a wireless electronic controller, fluid tubing, and a disposable rectal catheter in fluid communication with the tubing. The rectal catheter has a retention balloon and a waste control valve. The fluid tubing contains two or three separate lumens for irrigation fluid and retention balloon inflation/deflation and optionally for waste control valve actuation. None of the lumens ever communicates with any other lumen. A hydraulic control circuit has a pump that pumps in one direction only but, with suitable control valves, is able to pump water to and from the retention balloon and to and from an optional waste control valve. A water temperature sensor is mounted in the pump base unit at a thin-wall section. The temperature sensor sends a signal to a controller which provides an indication of whether the water temperature is suitable for use.

KIT FOR WASHING AN INTESTINAL ANASTOMOSIS IN SITU
20220240938 · 2022-08-04 ·

A kit including a device for intestinal anastomosis enema in situ, and an anastomosis protection device comprising a flexible external sheath connected to a stent located downstream of the sheath and designed to be anchored upstream of the anastomosis. The enema device has: a perforated, tubular element of annular shape that can distribute an enema composition, upstream of the anastomosis, a supply tube one end of which emerges in the tubular element and one end of which is open to injection means designed to deliver the composition into said tubular element, holding means for the tubular element upstream of the anastomosis.

MEDICAL DEVICE AND TREATMENT METHOD
20220240979 · 2022-08-04 ·

Medical devices and methods for puncturing tissue in a patient. The devices include a needle with a rigid proximal shaft, a flexible distal shaft, and a distal tip. The distal tip includes an electrode for delivering energy to puncture a tissue. In some embodiments, the distal shaft includes a superelastic material. In other embodiments, the distal shaft includes both a superelastic material and a non-superelastic material. The distal shaft includes shape memory enabling formation of an anchor within the patient.

Surgical instrument for suction and irrigation
11383018 · 2022-07-12 · ·

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.

Features to promote removal of debris from within ultrasonic surgical instrument

An instrument includes an ultrasonic blade, a first fluid port, an irrigation member, a second fluid port, and a fluid communication assembly. The ultrasonic blade defines a distal opening. The ultrasonic blade is operable in a first mode to emulsify tissue that is distally positioned relative to the ultrasonic blade. The ultrasonic blade is further operable in a second mode to transect and seal tissue that is transversely positioned relative to the ultrasonic blade. The first fluid port is in communication with the distal opening of the ultrasonic blade. The irrigation member is positioned adjacent to the distal end of the ultrasonic blade. The second fluid port is in communication with the irrigation member. The fluid communication assembly is configured to couple the first fluid port with a fluid source, couple the first fluid port with a suction source, and couple the second fluid port with the fluid source.
