A method for collecting and washing shed blood includes providing a blood salvage reservoir and a blood salvage system. The user may connect a vacuum inlet port on the reservoir to a vacuum outlet port on the salvage system, connect an inlet port on the reservoir to a patient, and connect a vacuum source to a vacuum connection port on the salvage system. The method may then (1) draw a vacuum on the reservoir to draw shed blood into the reservoir, (2) disconnect the reservoir from the surgical field and salvage system, and (3) connect a second reservoir. The first blood salvage reservoir may then be connected to an automated blood processing system, and the collected blood may be introducing into the automated blood processing system and washed. The blood processing system may then return a portion of the washed blood to the patient.

A surgical handpiece includes a housing gripped by a user; an aspirating flow path member that is accommodated in the housing, and aspirates a liquid; and an aspiration pipe that is held by the housing, and is connected to the aspirating flow path member via interference fitting so as to aspirate the liquid. At least one of the aspirating flow path member and the aspiration pipe includes a sealing portion for realizing the interference fitting, which is bulged toward a mating member of the interference fitting.

A surgical handpiece includes a housing gripped by a user, and an aspiration pipe that is attachably and detachably held by the housing and aspirates a liquid.

A system for providing a real-time indication of a location of the distal tip of a medical device in living tissue. The system may include an injection scanning printer that provides a visual indication of detected features to improve the injecting process. Safety needles configured to detect nerves, arteries, veins, or other physiological features upon needle placement but prior to injecting are also provided.

A closed system for harvesting fat through liposuction, concentrating the aspirate so obtained, and then re-injecting the concentrated fat into a patient comprises as its main components a low pressure cannula having between about 7 to 12 side holes of about 1-2 mm by 2.0 to 4.0 mm, a spring loaded syringe holder with a constant force or coiled ribbon spring to apply a substantially constant pressure over the full excursion of the plunger, and a preferably flexible collection bag which is also preferably graduated, cylindrical over most of its body and funnel shaped at its bottom, all of which are connected through flexible tubings to a multi-port valve. The multi-port valve has two flutter/duck bill valves which restrict the fluid flow to a one way direction which effectively allows the syringe to be used to pump fat out of a patient and into a collection bag in a continuous manner. After the bags are centrifuged to concentrate the fat, the excess fluids are separated and the valve is re-connected to permit the syringe pump to reverse fluid flow to graft the concentrated fat back into the patient.

A neurovascular catheter extension segment is provided, such as for distal neurovascular access or aspiration. The neurovascular catheter extension segment includes 1) an elongate flexible control wire having a proximal end and a distal end and 2) a tubular extension segment having a side wall defining a central lumen carried by the distal end of the control wire. The side wall of the tubular extension segment includes a tubular inner liner, a tie layer separated from the lumen by the inner liner, a helical coil surrounding the tie layer, and an outer jacket surrounding the helical coil. The extension segment may be introduced into the proximal end of a neurovascular catheter and advanced distally to extend beyond the catheter and thereby extend the reach of the catheter.

The illustrative embodiments described herein are directed to an apparatus, system, and method for storing liquid from a tissue site. The apparatus may include a drape having an aperture, and a fluid pouch coupled to the drape such that the fluid pouch is in fluid communication with the aperture. In one embodiment, the fluid pouch is operable to transfer reduced pressure to the aperture such that the liquid from the tissue site is drawn into the fluid pouch. The fluid pouch may have a cavity that stores the liquid that is drawn from the tissue site. In another embodiment, the fluid pouch may include at least one baffle. The fluid pouch may also include a fluid channel at least partially defined by the at least one baffle. The fluid channel may be operable to store liquid from the tissue site when reduced pressure is applied through the fluid channel.

Various implementations of a drainage catheter device include an outer drainage catheter and a distal portion. The outer drainage catheter has a proximal end and a distal end. The distal portion is adjacent the distal end of the outer drainage catheter and extends straight in a first configuration and forms a plurality of loops in a second configuration. A surface of the distal portion that faces radially inward in the second configuration defines a plurality of openings.

The present disclosure concerns embodiments of multi-lumen cannulae that can be used in various different medical procedures. The multi-lumen cannulae can comprise an elongated body comprising multiple different ports that connect to the various different sidewall lumens contained within the elongated body. The multi-lumen cannulae can also comprise a central lumen that extends through the entire elongated body and can be fluidly connected to the various different sidewall lumens. The multi-lumen cannulae can further comprise two balloons on the exterior of the elongated body, which can be used to isolate the right atrium of a patient's heart.

The infant nasal suction apparatus is disclosed for clearing the nasal passages of small babies and toddlers. The invention provides stress-free mucus extraction and allows the child to breathe easily and freely. The nasal suction apparatus is comprised of the suction housing, which includes the motor, battery, suction level adjustment controls, and an on/off switch. A collection container is removably connected to the suction housing, and a fluid conduit is connected to the container and adapted for placement in a nostril. The infant nasal suction apparatus is arranged for the removal of excess fluid and mucus from an infant nasal passageway and is controlled by the provided speed adjustment controller.
