Patent CA-1319794-C (CA)
Inventor: GASKILL HAROLD V III
IPC: A61F2/02
Filed: 1988-06-17
Granted: 1993-07-06
Abstract: The intravascular artificial organ is comprised of a flexible, hollow, semipermeable catheter containing living cells or tissue. The catheter is constructed of material with a pore size resulting in a molecular weight cutoff of approximately 50,000 Daltons. This pore size permits oxygen, glucose, and hormones to diffuse freely into and out of the organ. By contrast, cells of the host immune system cannot gain access to the cells or tissues within the organ and destroy them. Thus, it is possible to load the intravascular artificial organ with cells and tissues of immunologically foreign individuals, animals, bacteria or plants. The preferred embodiment consists of a double lumen catheter connected to two percutaneous access ports permitting flushing and reloading of the organ without removing it from the body.

Granted: 1992-03-31
Abstract: ABSTRACT OF THE DISCLOSURE      A process is provided herein for producing a lysin-free phage inoculum.  The process includes first inoculating a growing Streptococcal culture with phage.  The culture is incubated for a plurality of  lytic cycles of phage until  the cells  are completely lysed to obtain a lysate.  Finally cell debris and free lysin are removed from the lysate to form a lysin-free phage suitable for use as an inoculum.   The advantages of the new process for phage production are three-fold.  The amount of phage required to generate a new batch of phage inoculum is greatly reduced and the number of phage produced per initial phage is improved 104 fold.   In addition,  the phage lysate used as inoculum for phage production may contain active lysin since lysis "from without" does not occur because of the high dilution factor.

Title: Thrombin derived polypeptides; compositions and methods for use
Inventor: GLENN KEVIN C
IPC: A61K38/48
Filed: 1989-04-06
Granted: 2000-10-03
Abstract: Thrombin is now known to mediate a number of potent biological effects on cells bearing high-affinity thrombin receptors. These effects depend, at least in part, upon receptor occupancy signals generated by thrombin's interaction with the high affinity thrombin receptor. The present inventors have formulated synthetic thrombin derivatives capable of selectively stimulating or inhibiting thrombin receptor occupancy signals. The stimulatory thrombin derivatives to bind to cell surface thrombin receptors .and stimulate DNA synthesis in cells treated with non-mitogenic concentrations of alpha-thrombin or phorbol myristate acetate. Thus, these peptides, which hame both a thrombin receptor binding domain and a segment of amino acids with a sequence common to a number of serine proteases, appear to generate receptor-occupancy dependent mitogenic signals. The inhibitory derivatives, which have no serine esterase conserved amino acid sequences bind to thrombin receptors without generating receptor-occupancy dependent mitogenic signals. This invention describes the peptides and methods for using them to promote cell growth and wound healing or to inhibit scar formation, tissue adhesions. and tumor metastasis and angiogenesis.

Title: Device for reducing fibrous products
Inventor: WALLER MARTIN
IPC: B02C23/36
Filed: 1989-06-16
Granted: 1993-05-25
Abstract: ABSTRACT DEVICE FOR REDUCING FIBROUS PRODUCTS A macerator for reducing soiled paper pulp products such as bedpans and the like has a housing (18) which is closeable by means of a lid (16) which is provided with an internal spray (72).  At the base of the housing (18) is a rotatably mounted agitating blade (48) having two cutting edges inclined in different directions to the rotational axis of the cutting blade.   The agitating blade is located and/or orientated asymmetrically within the housing.  In particular, the axis of rotation of the agitating blade (48) may be inclined to the longitudinal axis of the housing, and the axis of rotation may or may not intersect the longitudinal axis of the housing.   Alternatively, or in addition, the agitating blade (48) may be displaced or offset from the longitudinal axis of the housing (18).  This results in a high hydraulic shear between the agitating blade and the internal wall of the housing on liquid within the housing.  The effect is pronounced when the blade is closly spaced from the wall of the housing.  A valve which is particularly useful with the macerator has a valve closure member (52) is in the form of a relatively rigid sealing portion (56) connected to a flexible diaphragm portion (54).  A pressure chamber is formed behind the sealing member and the diaphragm portion, and the sealing portion may be urged into engagement with a valve seat by application of fluid pressure behind the diaphragm and the sealing member.
