Patent Issued for Structure for Use as Part of a Medical Device

February 10, 2014

By a News Reporter-Staff News Editor at Biotech Business Week -- According to news reporting originating from Alexandria, Virginia, by NewsRx journalists, a patent by the inventor Ostrovsky, Isaac (Wellesley, MA), filed on December 17, 2008, was published online on January 28, 2014 (see also Biotechnology Companies).

The assignee for this patent, patent number 8636270, is Boston Scientific Scimed, Inc. (Maple Grove, MN).

Reporters obtained the following quote from the background information supplied by the inventors: "Medical devices are commonly used to access remote regions of the body to deliver diagnostic or therapeutic agents to those regions and to perform surgical procedures on those regions. For example, endoscopes may use body airways and canals to access the colon, esophagus, stomach, urethra, bladder, urethra, kidneys, lungs, bronchi, uterus, and other organs. Catheters may use the circulatory system as pathways to access treatment sites near the heart or may use the urinary tract to access urinary regions.

"Some medical devices can be introduced into the vasculature of the body of the patient through a large artery such as those found in the groin or in the neck of a human or other mammal. These devices are often passed through ever-narrower arteries until they can reach the operative site inside the body. Many such pathways may curve, loop around, and even wind back.

"Catheters are described in various patents, published patent applications, and other publications. See, for example, U.S. Pat. No. 3,924,632 and published U.S. Patent Application 2006/0111649."

In addition to obtaining background information on this patent, NewsRx editors also obtained the inventor's summary information for this patent: "The present invention generally relates to a low cost, flexible, and torqueable structure for use as part of a medical device and also methods of making such a structure. The structure can be manufactured without the use of expensive tubing or costly, time-consuming, and complicated laser cutting operations, and also without the need for one of more layers (of, for example, braided wire or other such material), yet still achieved the desired flexibility and torqueability. The structure can be formed simply of a coiled wire that is fed through a laser cut machine to join or weld together at least some of the adjacent turns of the coil. The laser cut machine would be set to apply an appropriate amount of laser energy to fuse or weld those adjacent turns but not to cut thought the coiled wire, and the coil would be rotated as it is fed longitudinally through the machine to create a winding pattern of weld locations.

"In one aspect, the invention features a structure for use as at least a portion of a medical device, and the structure comprises a coil formed of a wound element. The coil includes a plurality of adjacent windings and each winding has a pitch. A material is disposed in a portion of the region between adjacent windings such that the material connects adjacent windings of the coil and allows torque to be transmitted between adjacent windings.

"The wound element can be a flat wire, and the flat wire can be metal or other synthetic or natural material. The element typically will be made of one or more materials that are acceptable for use within the body of a patient.

"The structure can include an outer sheath disposed over the coil. The outer sheath can be made from a variety of known materials and can be heat shrunk to fit over the coil. The structure can also include and inner tube, disposed in the inside of the coil and with a proximal end and a distal end and a lumen extending from the proximal to the distal end of the coil."
