US Patent:

7753882, Jul 13, 2010

Filed:

Sep 10, 2007

Appl. No.:

11/852998

Inventors:

Roger Susi - Winter Park FL, US

Assignee:

Iradimed Corporation - Winter Park FL

International Classification:

A61M 37/00

US Classification:

604131

Abstract:

Liquid infusion apparatus includes non-magnetic materials in a pumping structure and drive motor therefor, and in a controller that supplies drive signals to the motor to facilitate convenient operation in intense magnet fields without distorting the magnetic fields and without radiating objectionable radio-frequency interference.

US Patent:

Filed:

Jul 14, 2008

Appl. No.:

12/172906

Inventors:

Roger Susi - Winter Park FL, US
David Hefele - Altamonte Springs FL, US

Assignee:

Iradimed Corporation - Winter Park FL

International Classification:

A61M 1/00

US Classification:

604151, 600411

Abstract:

It may desirable to monitor or control a pump remotely. For example, the pump may be positioned near the patient, with remote control or monitoring of the pump occurring in a control room. In one exemplary embodiment, the pump is used in an MRI environment. In another exemplary embodiment, the pump is used in a hyperbaric chamber. The pump may monitor one or more physiological parameters and transmit them to the remote. The pump may also transmit information relating to the pump's operation. The pump may send the device and/or physiological data using one or more packets. The packets may consist of low priority sequential packets and high-priority asynchronous packets. The high-priority packets may enable the real-time monitoring of a patient's heart beat or other physiological parameter.

Appl. No.:

12/834694

Inventors:

Roger E. Susi - Winter Park FL, US

Assignee:

Iradimed Corporation - Winter Park FL

International Classification:

A61B 5/055

US Classification:

600411, 600420, 604131, 604151

Abstract:

A patient infusion and imaging system includes a magnetic resonance imaging (MRI) scan room shielded from electromagnetic interference and image acquisition equipment positioned within the MRI scan room. The system further includes an IV liquid infusion apparatus configured to be positioned at any location within the MRI scan room without introducing image-degrading RF interference and without being affected by magnetic fields produced by the magnetic source. The IV liquid infusion apparatus includes a pump disposed to receive a liquid conduit and to transfer IV liquid through the liquid conduit from a liquid IV container source, a non-magnetic ultrasonic motor, and a non-magnetic controller configured to selectively actuate the motor to drive the pump, and thereby transfer liquid from the IV container source through the liquid conduit at a controllable volumetric rate.

Appl. No.:

12/138172

Inventors:

Roger E. Susi - Winter Park FL, US

Assignee:

Iradimed Corporation - Winter Park FL

International Classification:

A61M 31/00
A61M 37/00

US Classification:

604500, 604131

Abstract:

Liquid infusion apparatus includes non-magnetic materials in a pumping structure and drive motor therefor, and in a controller that supplies drive signals to the motor to facilitate convenient operation in intense magnetic fields without distorting the magnetic fields and without radiating objectionable radio-frequency interference. A non-MRI-compatible liquid infusion apparatus is temporarily replaced with MRI-compatible, non-magnetic liquid infusion apparatus without disconnecting patient from an installed intravenous infusion set to continue infusing liquid within the MRI environment.

Appl. No.:

12/494166

Inventors:

Roger E. Susi - Winter Park FL, US

Assignee:

IRadimed Corporation - Winter Park FL

International Classification:

A61M 5/00
A61M 5/31
A61M 31/00

US Classification:

604250, 604500

Abstract:

An apparatus and method are disclosed for controlling infusion of liquid into a patient using a peristaltic pump. The liquid infusion apparatus includes a liquid conduit having a proximal segment, a distal segment and an intermediate segment. The liquid infusion apparatus also includes a flow valve in fluid communication with the intermediate and distal segments. The flow valve includes a shuttle member slidably disposed within a housing about the distal segment, the shuttle member being configured for lateral movement relative to an elongated axis of the distal segment. The shuttle member is configured to operate in a first configuration to impede fluid flow through the liquid conduit and in a second configuration for which fluid flow through the liquid conduit is unimpeded. The shuttle member includes a resilient grasper for selectively engaging and disengaging a mating actuator resiliently received by the grasper.
