Blood filter

A blood filter device having an iron-chelating molecule, a haem-binding molecule and a haemoglobin-binding molecule bound to a support. Use of the device in a vessel containing blood, for example a blood bag or a flow line, removes haemolysis-derived components from the blood.

Evacuation system
11534539 · 2022-12-27 · ·

An evacuation system and method for removing and/or treating gaseous and/or particulate byproducts of surgical procedures includes an end effector such as a side vent trocar, an operating room tower or the equivalent, a disposal vessel, a vacuum source and optionally a filter. The end effector may be coupled to the tower by a conduit, the tower may be coupled to the collection tank by a conduit, and the collection tank may be coupled to the vacuum source. Gaseous and/or particulate byproducts may flow from the surgical site through the trocar, conduits, tower tank and filter, and the flow may be regulated at least in part by the components of the system.

Tangential flow filter system for the filtration of materials from biologic fluids

Systems and methods for filtering materials from biologic fluids are discussed. Embodiments may be used to filter cerebrospinal fluid (CSF) from a human or animal subject. In an example, CSF is separated into a permeate and retentate using a tangential flow filter. The retentate is filtered again and then returned to the subject with the permeate. During operation of the system, various parameters may be modified, such as flow rate and waste rate.

APPARATUS AND METHODS FOR ACCESSING THE LYMPHATIC SYSTEM

Systems and methods are provided for performing a medical procedure within a patient's body that involves a thoracic duct including an ostium communicating with the patient's venous system. A distal end of a catheter is introduced through the patient's venous system into a body lumen adjacent the ostium of the thoracic duct. An expandable member on the distal end of the tubular member may be expanded adjacent the ostium, e.g., within the body lumen or the thoracic duct itself, and used to isolate the thoracic duct from the body lumen, whereupon a medical procedure may be performed via the thoracic duct. For example, lymphatic fluid may be removed from the thoracic duct through a lumen of the tubular member and/or one or more agents may be introduced into the thoracic duct through the tubular member.

Device and method for resizing adipose and other tissues for implantation
11612683 · 2023-03-28 · ·

A deagglomerator for use in resizing masses of cells is disclosed. The deagglomerator may include a plurality of apertures defined by a plurality of front and back edges. The masses of cells may be passed through the plurality of apertures from the front to the back, and from the back to the front, repeatedly. The deagglomerator may also include a plurality of blades that may aid in the deagglomeration of the cell masses. The deagglomerator may be configured between two syringes so that the tissue may be passed back and forth from the first syringe through the device to the second syringe, and then back again from the second syringe through the device and to the first syringe. In this way, the masses of cells may be properly deagglomerated.

Device for treating fat cells taken from a patient and intended for a transplant
11602587 · 2023-03-14 · ·

The present invention relates to a device and a method for FIG. 2 treating fat cells taken from a patient and intended for a transplant. More specifically, it relates to a device and a method by suctioning which makes it possible to separate the viable fat cells from the residues and elements which are not transplantable. The device is a device for treating adipose tissues (G) connected to a suctioning means (M), consisting of a sealed treatment chamber (A) comprising a means for connection (17) to said suctioning means (M), a means for inlet (13) of said adipose tissues before treatment, a filtration means (3) and at least one means for outlet (20) of said adipose tissues (G) after treatment, said filtration means (3) comprising a conically shaped external wall (3 1, 3) comprising a narrow base (55) attached to an impeller (25) and an internal sieving means (30) connected to the output means (20), said impeller (25) being subjected to the air pressure reduction created by the suctioning means (M) and constituting a rotary mechanical actuating means for actuating said filtration means (3).

Connective tissue progenitor cell aspiration and processing system
11602588 · 2023-03-14 · ·

A method of treating soft tissue conditions. A harvesting device is provided. The harvesting device is operably connected to a tissue processing device using tubing. An aperture is formed in a bone. The bone has an interior. The harvesting device is inserted through the aperture in the bone and into the interior of the bone. The harvesting device is manipulated to dissociate connective tissue progenitor cells in the interior of the bone. Tissue is aspirated from the interior of the bone. The connective tissue progenitor cells are separated from the aspirated tissue. The separated connective tissue progenitor cells are injected in a region of a body that is experiencing a soft tissue condition to treat the soft tissue condition.
