Abstract:
A device for separating and isolating components of a biological fluid comprising a container for containing the fluid to be processed, a tube cap assembly for closing the container while providing filling and extraction communication therewith, a float assembly disposed within the container for funneling and controlling biological fluid flow into an inverted domed shaped isolation chamber within the float and controlling the biological fluid flow out of the isolation chamber for effecting an encapsulation or a sealed isolation of at least one component or fraction of the biological fluid flow within the isolation chamber during a centrifugation process. The device further comprising a flexible tube for connecting an extraction passageway disposed within the float assembly and an extraction valve of the tube cap assembly for allowing extraction of at least the one component or fraction encapsulated or isolated within the chamber.

Adipose Tissue Graft For Wound Healing

US Patent:
2013007, Mar 21, 2013
Filed:
Sep 20, 2012
Appl. No.:
13/623576
Inventors:
John Chapman - Sacramento CA, US
International Classification:
A61M 37/00
US Classification:
604522
Abstract:
An improved method for preparing an adipose tissue biocomposite graft to serve a wide range of medical applications is presented. In particular, the embodiments consider a performing lipoplasty to derive a plurality of adipose tissue fragments containing at least one viable stem cell from a donor, harvesting said plurality of adipose tissue fragments from said donor, placing said plurality of adipose tissue fragments in contact with appropriate concentrations of a thrombin source and a fibrinogen source to achieve an appropriate gelling reaction and applying the mixture of said adipose tissue fragments, said thrombin source and said fibrinogen source to a wound site of the donor so as to promote wound healing. The adipose biocomposite graft of the present invention can be easily processed, molded and customized to precise dimensions. The present invention employs a three dimensional mold cavity to prepare multiple castings of said adipose tissue biocomposite grafts for an individual donor.

Method For Separating A Sample Into Density Specific Fractions

US Patent:
2012006, Mar 15, 2012
Filed:
Aug 19, 2011
Appl. No.:
13/199119
Inventors:
John R. Chapman - Sacramento CA, US
Rodney Sparks - Antelope CA, US
Philip H. Coelho - Sacramento CA, US
International Classification:
B01D 21/26
US Classification:
494 37
Abstract:
The centrifugation vessel includes an outer wall containing an interior space. A dam defines a barrier which divides the interior space into at least two regions including a catch basin defining a higher gee region and a reservoir defining a lower gee region. These regions are joined together over the dam. The dam includes a face which is preferably tapered to enable optimization of speed of separation of a sample placed within the vessel. The vessel is usable in a biological sample processing method by having the higher gee region of the vessel configured to have an elongate form and the volume optimized for collection of a higher density fraction of the sample. Supply and withdrawal tubes extend into the regions for reliable extraction and separate collection of differing density fractions after separation by centrifugation.

Stem And Progenitor Cell Compositions Recovered From Bone Marrow Or Cord Blood; System And Method For Preparation Thereof

US Patent:
2012017, Jul 5, 2012
Filed:
Mar 15, 2012
Appl. No.:
13/385951
Inventors:
Philip H. Coelho - Sacramento CA, US
Bruce A. Baker - Placerville CA, US
John R. Chapman - Sacramento CA, US
Junzhi Li - Gold River CA, US
Prince Emmanuel - Sacramento CA, US
Robert S. Childers - Lincoln CA, US
International Classification:
C12N 5/0789
US Classification:
435325
Abstract:
The invention includes compositions of stem and progenitor cells recovered from bone marrow or cord blood containing most of the viable CD34+ cells and substantially depleted of red blood cells resident in the original sample, without any xenobiotic additives to aid cell separation. The invention also includes a system and method for preparing the compositions. The system includes a bag set and a processing device, which utilizes an optical sensor, microcontroller, servo motor, accelerometer, load cell, and battery. The system and method utilize centrifugation to stratify the cells into layers and then separate and transfer the stem cells into a stem cell bag. The processing device's microcontroller receives input from the device's accelerometer, load cell and optical sensor to direct the metering valve in the bag set to open and close to permit the transfer of as many stems cells as possible with as few red cells as possible.
