Power Medical Interventions (PMI; Langhorne, Pennsylvania) has filed a registration statement with the Securities and Exchange Commission for a proposed initial public offering of up to $100 million, though the per-share price and number of shares to be offered have not yet been disclosed.

The company, which makes cutting and stapling products used in open and endoscopic procedures, including bariatric surgery, colorectal and thoracic surgery, said it intends to use the funds for working capital, expansion of sales and marketing, continuation of R&D, expanded manufacturing, capital equipment and possible acquisitions.

PMI has developed the micro-robotic, computer-assisted SurgASSIST system used to cut tissue, close wounds and reconnect anatomical structures, which the company calls "a preferable alternative to hand suturing."

The company said in its filing that it has sustained losses since its 1999 launch, including a net loss of $28.3 million for the year ended Dec. 31, 2006. As of that date, it had an accumulated deficit of $137.1 million.

Among risks listed by the company, it said it is involved in two appeal proceedings in Germany in connection with two patent-infringement lawsuits against it. The lawsuits allege that certain of the company's products infringe three European patents held by Ethicon Endo-Surgery (Cincinnati).

Between May 2002 and June 2005, the company noted that the FDA has conducted three inspections of its facilities, and each of those inspections resulted in the issuance of a Notice of Inspectional Observations, or Form 483. Certain observations regarding its processes to handle customer complaints, submit medical device reports, initiate corrective and preventive actions, and to conduct internal quality audits were identified by the FDA as areas of possible non-compliance with FDA regulations.

From Feb. 13 to April 26, 2007, the FDA conducted an additional inspection of the company's facility in Langhorne, Pennsylvania. A Form 483 from that inspection generated 24 inspectional observations, including the failure to properly process customer complaints, failure to submit to the FDA medical device reports or to submit them within regulatory timeframes, and the lack of reporting a field action.

The company has applied for the listing of its common shares on the NASDAQ Global Market under the symbol PMII.

• Pluristem Life Systems (Haifa, Israel), a biotherapeutics company developing products for malignant, degenerative and auto-immune indications, reported closing on a private investment in the company of about $13.5 million.

The financing, which is a continuation of the investment disclosed in February, included as investors the Technion-Israel Institute of Technology (Haifa) and inventors who collaborated on the technology and whose patents were acquired by Pluristem.

"The response to this capital raise was extraordinary and provides us with the financing we need to complete the development of our first product, PLX-I, and explore the use of our placental expanded mesenchymal stem [PLX] cells for other clinical indications," said Zami Aberman, CEO of Pluristem.

Pluristem is developing PLX-I as an alternative to bone marrow transplantation. PLX-I is an allogeneic product, based on supplementing hematopoietic stem cells contained in umbilical cord blood to improve the effectiveness of HSCs engraftment and shorten recovery times. PLX-I mesenchymal stem cells were proven to increase the engraftment of HSCs from CB by up to five fold in a pre-clinical study.
