Filed:

Nov 21, 1997

Appl. No.:

08/975688

Inventors:

Livingston B. Morris - Devon PA

Assignee:

Therakos, Inc. - Exton PA

International Classification:

A61M 3500

US Classification:

604 609, 604 61, 604 501, 21032162, 21032175, 21032172, 2102572

Abstract:

An apparatus controls movement of fluids during an extracorporeal blood treatment session. A hollow cassette enclosure has a plurality of fluid input ports for receiving fluids into the enclosure and a plurality of fluid output ports for expelling fluids from the enclosure. Internal fluid passageways disposed within the hollow enclosure are provided for coupling together the fluid input ports, and the fluid output ports. At least one internal valve is disposed within the hollow enclosure for controlling movement of the fluid within the hollow enclosure. A filter is integrated into the cassette to filter the blood passing therethrough.

Securing System For Centrifuge Chamber

US Patent:

53083091, May 3, 1994

Filed:

Dec 23, 1992

Appl. No.:

7/996298

Inventors:

Livingston B. Morris - Devon PA

Assignee:

Therakos, Inc. - West Chester PA

International Classification:

B04B 900

US Classification:

494 85

Abstract:

An improved apparatus for automatically retaining a removable chamber during operation, in a system for separating and irradiating multi-component fluids. A clamp arm that having two ends is provided: the first acts as a securing means, the second contains the clamp arm center of mass. The clamp arm is pivoted on the rotating chuck near the interface of the rotating chuck interior and the removable chamber exterior. The pivot allows for rotation of the clamp arm about the pivot, the pivot being located between the first end with the securing means and the second end containing the center of mass. When the chuck is rotating, the end of the clamp arm containing the center of mass rotates outward, causing the clamp arm securing means to pivot above the removable chamber thereby securing it in place.

Photoactivation Light Array

US Patent:

55699286, Oct 29, 1996

Filed:

Dec 14, 1993

Appl. No.:

8/166494

Inventors:

Kyu H. Lee - Bryn Mawr PA
Livingston B. Morris - Devon PA
David W. Palmer - late of Conshohocken PA

Assignee:

Therakos, Inc - West Chester PA

International Classification:

A61N 506

US Classification:

2504941

Abstract:

Light arrays for use in systems for separating and irradiating blood are disclosed. In accordance with the present invention, the light array has one or more bulbs with electrical connecting leads and first and second support members connected to the bulbs. The second support member preferably includes a connector for receiving the electrical leads. The support members preferably define an end surface and an interior surface, wherein the support members are disposed adjacent the bulbs so the end surfaces are opposed to define a channel, providing a space where tubing carrying blood or other fluids can be disposed without interfering with the array. The bulbs are most preferably attached to the support members using flexible self-locking straps, and in embodiments using two or more bulbs, the bulbs are also preferably held together by one or more straps. Improved mounting systems for connecting the array to the instrument by one or more spring mounts are also disclosed. In certain preferred embodiments, one of the support members is a circuit board and includes a microcircuit for controlling the operation of the array using a clock/timer circuit for determining a total time of activation for the array, whereby upon reaching a predetermined value of the total time of activation, the clock/timer circuit disables the light array.

Apparatus For Pumping Fluid At A Steady Flow Rate

View page

US Patent:

59219513, Jul 13, 1999

Filed:

Nov 19, 1997

Appl. No.:

8/974200

Inventors:

Livingston B. Morris - Devon PA

Assignee:

Therakos, Inc. - Exton PA

International Classification:

A61M 3700

US Classification:

604 6

Abstract:

An apparatus for pumping fluid at a steady rate. A first drive chamber having a movable outer surface, and a second drive chamber having a movable outer surface are provided. The apparatus further includes a block having a plurality of internal passages including a first passage for receiving the fluid into the block and a second passage for discharging the fluid from the block at the steady rate. The block has first and second internal chambers which are in fluid connection with the first and second passages. The first internal chamber has a first flexible surface for mating with the movable outer surface of the first drive chamber, and the second internal chamber has a second flexible surface for mating with the movable outer surface of the second drive chamber. At least one actuator is provided for applying positive pressure to the first flexible surface while simultaneously applying negative pressure to the second flexible surface and for applying negative pressure to the first flexible surface while simultaneously applying positive pressure to the second flexible surface. The actuator is respectively coupled to the first and second flexible surfaces by the first and second drive chambers.

Multicomponent Fluid Separation And Irradiation System

View page

US Patent:

49214730, May 1, 1990

Filed:

Feb 2, 1989

Appl. No.:

7/305339

Inventors:

Kyu H. Lee - Bryn Mawr PA
Livingston B. Morris - Devon PA

Assignee:

Therakos, Inc. - Westchester PA

International Classification:

B04B 1100
B04B 510

US Classification:

494 27

Abstract:

A multicomponent fluid separation and irradiation system is described containing a centrifuge drum and a source of radiant energy located within the drum. In a first embodiment a disposable rigid separation/irradiation chamber is provided with a cylindrical outer compartment located within the drum and opposing the radiant energy source. Whole blood is supplied to the chamber through a dynamic seal located at the center of the chamber. As the chamber is rotated, blood is separated so that energy from the source passes through the inner wall of the chamber and the separated plasma layer to irradiate the buffy coat layer. In a second embodiment, one or both of the walls of the outer compartment of the chamber are flexible so that the chamber will expand as blood is pumped in and will collapse as blood is pumped out.

Accordion Fold Flat Plate Dialyzer

View page

US Patent:

40282520, Jun 7, 1977

Filed:

Jun 4, 1975

Appl. No.:

5/583648

Inventors:

Livingston B. Morris - Devon PA

Assignee:

Extracorporeal Medical Specialties Inc. - King of Prussia PA

International Classification:

B01D 3100

US Classification:

210321B

Abstract:

A support material is fed through mating elements which emboss transverse score lines thereon to form an accordion fold in the material. A single thickness of the folded support material is then interleaved with a permeable membrane and sealed in a housing to form a compact inexpensive flat plate dialyzer. Longitudinal channels are formed in the support material which materially improve distribution of fluids within the dialyzer.

Blood Product Irradiation Device Incorporating Agitation

View page

US Patent:

59515090, Sep 14, 1999

Filed:

Nov 19, 1997

Appl. No.:

8/971879

Inventors:

Livingston B. Morris - Devon PA

Assignee:

Therakos, Inc. - Exton PA

International Classification:

A61M 3700

US Classification:

604 4

Abstract:

Apparatus for treating human blood by irradiation. Exposure of a human blood product sample can be optimized by displacing a contiguous, self-contained arrangement, such as a bag member, while radiation is being emitted towards the contiguous, self-contained arrangement, and by maintaining a substantially constant distance between the radiation source and the at least one blood product held in the contiguous, self-contained arrangement. Also proposed is an arrangement in which at least a portion of the radiation source is displaced while radiation is being emitted towards the contiguous, self-contained arrangements holding the blood products in question. Further, an arrangement for cooling the radiation source is contemplated.
