ProUroScan System for Mechanical Imaging of Prostate

ProUroScan System for Mechanical Imaging of Prostate

Approved to make real-time, color images of men’s prostate glands, ProUroCare will next pilot the clinical technology in select medical centers

MINNEAPOLIS, May 1, 2012 /PRNewswire/ — ProUroCare Medical Inc. (OCTBB: PUMD), provider of proprietary medical imaging products, announced today it has received clearance from the U.S. Food & Drug Administration (FDA) for its ProUroScan™ prostate mechanical imaging (PMI) system. The approval paves the way for men and their families to receive high-resolution visual documentations as an aid in detecting prostate abnormalities that were previously detected by digital rectal examination (DRE). The ProUroScan system constructs color 2D and 3D “maps” of the prostate in real-time that, when in agreement with a DRE finding, can be permanently stored in electronic records for future analysis and comparison. ProUroCare’s patented tactile elasticity imaging technology, which uses a handheld pressure-sensing rectal probe and sophisticated image construction software to produce its prostate maps, represents a new imaging modality distinct from traditional ultrasound imaging.

The company plans to introduce the technology in 2012 to a limited number of top U.S. medical care centers in key major metropolitan markets. With assistance from Minneapolis investment firm Cherry Tree & Associates, LLC, ProUroCare has been actively seeking a strategic corporate partner with a strong sales and in-service support presence in the urologic market to fully commercialize its technology.

“This is a major milestone for the company, for physicians looking for more assurance and documentation in their evaluations and for men eager for more information to assess and make decisions about their prostate health,” said Rick Carlson, CEO of ProUroCare Medical. “A color image can go a long way in documenting a person’s prostate condition, and this development puts us one step closer to supplementing other screening measures with a helpful, high quality visual aid that can be referred and compared to over time.”

As a standard of care, the American Urological Association (AUA) currently recommends that beginning at age 40, men receive a DRE and a prostate specific antigen (PSA) blood test in their yearly physical, yet data from community-based studies suggest the positive predictive values of DRE and PSA combined achieve only a 56 percent predictive value. Furthermore, neither test creates a physical or visual record of the prostate. The ProUroScan system is being introduced as an adjunctive technology to a DRE for physicians to use to further clarify and document abnormalities associated with the prostate gland.

“Having a visual aid of irregularities can be so helpful to physicians and patients, particularly in the area of prostate care where decision-making is often difficult,” said Dr. Robert Weiss, a urologic oncologist with the Cancer Institute of New Jersey and a faculty member at Robert Wood Johnson Medical School who used the ProUroScan technology as part of its clinical trial process. “The quality and resolution of the images are excellent, providing an immensely valuable supplement to the DRE, where physicians must rely on a gloved finger to feel for changes in the size and shape of the gland.”

The prostate imaging system’s FDA 510(k) was first submitted by ProUroCare’s development partner Artann Laboratories, Inc. and later processed in accordance with the de novo provisions accounted for in Section 513(f)(2) of the Federal Food, Drug and Cosmetic Act. The FDA filings were supported by data from a 2009 National Institute of Health and National Cancer Institute-supported clinical study of patients evaluated at five leading U.S. medical centers, as well as an earlier study conducted specifically at the Robert Wood Johnson Medical Center in New Brunswick, N.J.

ProUroScan is an advanced medical imaging system that uses an array of sensors mounted on a rectal probe, a central processing unit and software and image construction algorithms to provide a real time color image of abnormalities in the prostate.

The system provides an image or record of the pressures that are generated from palpation of the posterior surface of the prostate using a rectal probe. The system’s operation is based on measurement of the stress pattern created when the probe is pressed against the prostate through the rectal wall. Temporal and spatial changes in the stress pattern provide information on the elastic structure of the gland and allow two-dimensional reconstruction of prostate anatomy and visualization of prostate mechanical properties. The prostate image is displayed on a screen that allows physicians to visualize tissue abnormalities in the prostate gland. In addition to the real time visual image, the results are stored electronically as a digital record.

The ProUroScan System probe is specially designed for the rectal anatomy to minimize patient discomfort. It is ergonomic for the clinician and similar to a traditional DRE for the patient. The probe utilizes highly sensitive pressure sensors located on the face of the probe head to palpate the prostate. The probe’s positioning system ensures that the person administering the scan examines the entire surface of the prostate, and assists prostate image construction.

To perform a scan, the clinician inserts the tip of the probe into the patient’s rectum and palpates the prostate. As the prostate is palpated, an image of the prostate is produced and displayed on the computer monitor, along with indicators of the amount of pressure being applied to help guide the clinician. The image that is generated during the evaluation shows the physician in real-time where abnormal tissue exists in an otherwise homogeneous soft tissue organ.

Mechanical “Elasticity” Imaging

Mechanical or elasticity imaging refers to a non-invasive analysis of tissue movement and displacement. The ProUroScan technique works by computing how tissue moves in response to pressure, thus evaluating its softness or stiffness. Sensors on the head of the probe collect a sequence of pressure patterns while the probe is pressed against the prostate. The device consequentially measures the prostate’s elasticity. Each scan produces an image of the prostate and compares elasticity measurements across the gland.

A Two- and Three-Dimensional Prostate Image

The image of the prostate that is created is designed to identify variations in tissue elasticity using a specially designed rectal probe. Once the image is created it can be utilized by the physician to assist in evaluating the results of an abnormal digital rectal exam for men and stored as an electronic record. Tissue that is confirmed by DRE as abnormal will exhibit less elastic properties and be represented by progressively darker areas on the image of the map as compared to normal tissue. During the real-time imaging examination, the physician can direct the probe to specific areas of interest as confirmed by DRE. The final composite image is saved in a file as a permanent electronic record and can be conveniently retrieved to view previous test results.

ProUroCare Medical out of Eden Prairie, MN has been cleared in the US to sell its ProUroScan tactile elasticity imager for visualizing the prostate.

The probe employs mechanical sensors that detect the stiffness of the prostate while it’s palpated, and the data is processed and the prostate displayed on the laptop for the physician to assess.
