DEVICES AND METHODS FOR SLURRY GENERATION
20210275351 · 2021-09-09 ·

The present invention involves the use of a small profile device for preparation and/or delivery of cold slurry into the human body. The cold slurry can be generated within the device itself or within a separate small chamber, both of which produce a cold slurry using a cooling source and an injectable fluid. The delivery device provides continued agitation to the fluid/slurry through rotation and/or vibration of blades within the device. The fluid/cold slurry is cooled/kept cool through the use of an external cooling device, such as a cooling sleeve, that at least partially surrounds the delivery device. The cooling sleeve can cool or maintain the temperature of the cold slurry through a number of mechanisms. The cold slurry can be delivered using a device in accordance with the present invention to any tissue inside the body, including subcutaneous fat, visceral fat, and brown fat.

Bone cement application device with closure on the delivery plunger
11103295 · 2021-08-31 · ·

One aspect relates to a device for producing a bone cement paste from a monomer liquid and a cement powder as parent components of the bone cement paste and for delivering the mixed bone cement paste, the device having a cartridge having a cylindrical interior. The interior of the cartridge is closed on the front side except for a delivery opening for expelling the bone cement paste. A delivery plunger is arranged in the interior of the cartridge.
