A fat harvesting system and related methods of harvesting and reinjecting fat that provides a medical professional with multiple technique options. Harvested fat can be subjected to a variety of pre-reinjection preparation steps within a single, self-contained reservoir such that the potential for contaminating the harvested fat is avoided. The fat harvesting system can be completely self-contained kit requiring no additional external systems or alternatively, can utilize available surgical suite systems, for example, vacuum to successfully harvest, prepare and reinject fat cells. The fat harvesting system can size harvested fat cells so as to be especially desirable for different injection locations in the body. The fat harvesting system is a single use, disposable system that requires no sterilization equipment and recovered and sized fat cells are maintained in a sanitary environment so as to avoid contamination that could result in having to discard recovered fat cells.

Described are methods, systems, devices for facilitation of intraluminal medical procedures within the neurovasculature. A catheter advancement device includes a flexible elongate body having a proximal end, a distal end, and a single lumen extending therebetween. The flexible elongate body has a proximal segment, an intermediate segment, and a tip segment. The proximal segment includes a hypotube coated with a polymer. The intermediate segment includes an unreinforced polymer having a durometer of no more than 72D. The tip segment is formed of a polymer different from the intermediate segment and has a durometer of no more than about 35D and a length of at least 5 cm. The tip segment has a tapered portion that tapers distally from a first outer diameter to a second outer diameter over a length of between 1 and 3

Surface debriding systems and instruments are provided that efficiently and effectively dislodge and remove debris, coatings, microorganisms and fluids from the dorsum of the tongue or other surfaces. The instrument has a debriding surface with cleaning elements and a number of spaced apart openings to a hollow interior that is configured to couple with a vacuum source. The shape of the openings may be configured to amplify suction force from the vacuum source. The system also has a vacuum source and a collecting vessel with backflow valves to store removed material and to stop movement of material into the vacuum source or back out to the instrument. The system can be self-contained or the instrument may be coupled to a dental high-volume evacuator (HVE) vacuum source.

A distal aspiration catheter comprises catheter body having a central lumen and at least one luminal channel. An aspiration source is configured to attach to a proximal end/luer hub of the central lumen. Each luminal channel includes one mandrel and a distal portion of the mandrel extends into a distal portion in the central lumen. When the aspiration source is activated, a clot/emboli lodged in a blood vessel is partially ingested into the distal portion of the central lumen. The distal portion of the mandrel can move into the partially ingested clot to induce clot fatigue. The fatigued clot can be removed completely by a single pass of the distal aspiration catheter.

An adaptable suction tubing apparatus for a surgical retractor is disclosed. The suction tubing apparatus comprises a suction tip connector, an extruded rectangular tubing and an end suction connector. All components also have side protrusions or bumps for nesting into top channels over the top surface of a surgical retractor. These side protrusions provides snug fit within a surgical retractor. Optionally the tubing can have double sided adhesive tape for placement over the top surface of a standard surgical retractor. The suction tubing apparatus is designed for one time use and has low profile and conformed to the contour of any retractors perfectly.

A suction catheter for fragmenting and removing obstructive material and thrombus from the body or other body cavities that comprises a tube-like body with a proximal and distal end and a pressure lumen and discharge lumen formed in the catheter body. At the distal end of the catheter is a suction opening adjacent to the opening of the nozzle injector formation. At the proximal end of the catheter the lumens are connected to an inlet port and a discharge outlet. A hub structure is coupled to the proximal end of the catheter tubular body and includes a pressure lumen for connecting a fluid source to the pressure inlet. At the proximal end of the tubular catheter a discharge lumen is connected at the proximal hub to a discharge reservoir. The suction port at the distal end of the catheter may be formed into a separate lumen within the catheter body and may include a guidewire lumen.

The tip segment is formed of a polymer different from the intermediate segment and has a durometer of no more than about 35 D and a length of at least 5 cm. The tip segment has a tapered portion that tapers distally from a first outer diameter to a second outer diameter over a length of between 1 and 3 CM.

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 gastric drainage device includes a tube with a drainage lumen and a hub to receive an inflation device. The tube includes an intragastric portion having a set of holes to permit gastrointestinal contents to pass from a stomach cavity into the drainage lumen. The gastric drainage device includes a bolster with a cylindrical port to receive the tube and a disc to hold the tube in place on a skin side of a gastrostomy site. The gastric drainage device includes a balloon formed around the intragastric portion of the tube, wherein the balloon and the intragastric portion of the tube may be passed through the gastrostomy site into the stomach cavity while the balloon is deflated. Accordingly, the balloon is inflatable within the stomach cavity using the inflation device to secure the gastric drainage device at the gastrostomy site while the gastrointestinal contents are drained from the stomach cavity.
