The present patent specification provides a medical device including an outer tube, an operation portion and a control portion. The operation portion is at least partially located in the outer tube. The control portion has a channel communicating with the outer tube along a first direction; a second end of the control portion is coupled with a first end of the outer tube so that the channel and the outer tube communicate with each other along the first direction. The control portion includes a control module including a suction control unit, a suction, a suction valve actuator and a switching unit. The suction control unit has a stopping unit and is configured to move along a second direction which is different from the first direction. The suction valve actuator is located at a side opposite the suction control unit with the channel therebetween and the suction valve actuator is configured to be activated by the suction control unit. The switching unit is configured to switch the work status of the operation portion.

A drive system for a handheld rotary medical device including a force absorption system incorporated in a drive coupling of the drive system is disclosed. The force absorption system may be included in the drive coupling whereby force absorption system absorbs linear forces aligned with a longitudinal axis of the drive coupling. As such, the force absorption system permits limited linear movement of a rotary surgical implement, which may be a shaver, burr or the like, relative to a drive shaft and handheld housing.

A method for capturing dislodged vegetative growth during a surgical procedure is provided. The method includes maneuvering, into a circulatory system, a first cannula having a distal end and an opposing proximal end, such that the first cannula is positioned to capture the vegetative growth en bloc. A second cannula is positioned in fluid communication with the first cannula, such that a distal end of the second cannula is situated in spaced relation to the distal end of the first cannula. A suction force is provided through the distal end of the first cannula so as to capture the vegetative growth. Fluid removed by the suction force is reinfused through the distal end of the second cannula. Subsequent to becoming dislodged, the vegetative growth is captured by the first cannula. A method for capturing a vegetative growth during removal of a pacemaker lead is also provided.

A surgical instrument may comprise a housing and a shaft a shaft extending within the housing. The shaft may include first and second ends. The shaft may be configured for rotation in response to either a robotic actuation of the shaft or a manual actuation of the shaft. The surgical instrument may also comprise a receiving member coupled to the first end of the shaft. The receiving member may be configured to releasably couple to a driver of a robotic manipulator to receive the robotic actuation from the driver to rotate the shaft and articulate an instrument component coupled to the shaft. The surgical instrument may also comprise a manual actuation component coupled to the second end of the shaft and extending from the housing. The manual actuation component may be configured to receive the manual actuation to rotate the shaft and articulate the instrument component coupled to the shaft.

A bone marrow aspiration device may include a housing having a proximal end and a distal end; a cannula, insertable into a tissue, extending from the distal end; a ratcheting mechanism coupled to the housing; a reservoir configured to receive a fluid; an actuator operatively coupled to the ratcheting mechanism and to a distal surface of the bone marrow aspiration device such that user-actuation of the actuator actuates the ratcheting mechanism to draw fluid through the cannula, into the housing, and into the reservoir, and retracts the cannula relative to the distal surface.

An apparatus including a housing, an electrical conductor, and a suction control valve. The housing forms a handle and a shaft. The housing defines a suction channel from a distal end of the shaft. The electrical conductor extends to the distal end of the shaft. The suction control valve is connected to the suction channel at the handle. The suction control valve includes a valve body having a first channel and a second channel connected to the first channel, where the first channel forms a portion of the suction channel; and a valve barrel rotatably connected to the valve body. The valve barrel includes a rotatable ring extending around the handle and forming a portion of the housing. The ring includes an orifice configured to be rotated into and out of registration with an end of the second channel as the ring is rotated about the valve body.

Aspiration systems and methods for controlling blood loss during thrombus removal are disclosed herein. The systems include an aspiration catheter, an aspiration tubing, a receptacle for collecting aspirated blood, a vacuum line coupled to the receptacle, and a sensor configured to measure a flow parameter associated with a liquid within an aspiration lumen. The systems further include a regulator configured to adjust a vacuum pressure within the vacuum line, and a vacuum controller operably coupled to the sensor and the regulator. The vacuum controller is configured to receive the flow parameter from the sensor, compare the flow parameter to a target range for the flow parameter, and send an automatic control signal to the regulator based on a comparison of the flow parameter to the target range. The automatic control signal causes the regulator to adjust the vacuum pressure within the vacuum line.

A suction instrument includes a proximal end, a distal end configured to be positioned within or adjacent to an anatomical passageway of a patient, and a suction lumen extending between the proximal and distal ends. The suction lumen is configured to provide suction at the distal end. A navigation sensor is disposed along a portion of the suction lumen and is operable to generate an electrical signal corresponding to a location of the portion within the patient. A coupling feature is disposed at the proximal end and is configured to releasably couple the proximal end with a body.

Systems and methods for nasal irrigation are provided in which a nasal irrigation device includes a source of saline solution, an effluent receptacle, a nasal interface, a vacuum source, a fluid passageway to communicate the source of saline solution with the effluent receptacle through the nasal interface and a nasal cavity of the user, and a switch and valve assembly for selectively controlling the vacuum source and flow of the saline solution through the fluid passageway. The saline solution source bottle is disposed relative to the device to provide gravitational inducement of saline solution to the nasal interface in engagement to the device user's nostrils. A combination of the gravitational inducement and the relative vacuum from an effluent receptacle generates a fluid flow for irrigating, cleansing and massaging the nasal cavity and ostia of a user. The entire device is assembled as a hand-held device for convenient lifting and disposal against the user's nostrils.

An aspiration system includes a pump and a control system in communication with the pump. The control system includes a microcontroller, an antenna configured to receive a signal, and a pump control board in communication with the microcontroller. The antenna is in communication with the microcontroller. Upon receiving the signal, the pump control board operates the pump to create negative pressure according to the signal.
