Patent number: 7871405Abstract: Medical devices can be positioned within a patient by use of apparatus and methods according to the invention. The apparatus and methods permit insertion of the medical devices into various locations of the patient's body without requiring removal and reinsertion of already-inserted medical devices. The apparatus and methods are typically used to place medical devices into a male patient's urinary system to treat a disease or condition. The medical devices can be cryoablation probes that are inserted into the prostate gland to treat prostate cancer, for example.Type: GrantFiled: September 20, 2007Date of Patent: January 18, 2011Assignee: Boston Scientific Scimed, Inc.Inventors: Brett Nowlin, Arthur R. Madenjian, Richard Tah, Weenna Bucay-Couto

Patent number: 6368356Abstract: The invention provides a means of boosting the mechanical performance of shaped shaped medical devices comprising polymer hydrogels, such as stents, so that they may be more easily inserted into or removed from the body. In one aspect, the invention provides shaped medical devices having increased mechanical strength and comprising both ionic and covalent crosslinks. In another aspect, the invention provides a shaped medical device having a heterogeneous polymer composition and a variable dissolution or degradation rate along its length. The shaped medical devices according to the present invention retain their shape and stiffness during insertion into the body and can swell and soften inside the body to enhance patient comfort.Type: GrantFiled: February 25, 2000Date of Patent: April 9, 2002Assignee: SciMed Life Systems, Inc.Inventors: Sheng Ping Zhong, Arthur R. Madenjian, Douglas E. Godshall, John M. Ronan, Samuel A. Thompson

Patent number: 5306246Abstract: An inflatable medical dilation balloon and methods for forming the same wherein the balloon member is comprised of a polymer bled including a predominant amount of a crystalline polymer, e.g. a polyester, and a compliance enhancing additive polymer, e.g. a polyolefin, in amount sufficient to interrupt the crystalline structure of the crystalline polymer. The amount is about 20% or less of the polymer blend. The balloon member formed of the polymer blend is inflatable for medical dilation, e.g. of the prostrate.Type: GrantFiled: September 11, 1992Date of Patent: April 26, 1994Assignee: Boston Scientific CorporationInventors: Ronald Sahatjian, Arthur R. Madenjian

Patent number: 4963313Abstract: An inflatable medical balloon is formed by fabricating a tubular preform having a tapered region at the end of the portion where the main body of the balloon will form to enable the corresponding transition section of the blown balloon to have a separately controllable thickness profile. The preferred method includes providing a tube of a selected resin of wall thickness and diameter suitable for being formed into a balloon, and selectively heating to drawing temperature a defined region of the tube at one or both ends of the portion of the tube from which the balloon is to be formed. Tension is applied in opposite directions to respective ends of the heated region to draw the region to a smaller diameter, thereby providing a preform having, at the end of the portion of the tube, a tapered, relatively small diameter region of material that has substantially no crystallization or molecular orientation.Type: GrantFiled: November 30, 1987Date of Patent: October 16, 1990Assignee: Boston Scientific CorporationInventors: Richard A. Noddin, Arthur R. Madenjian, Ralph J. Barry, Jr.

Patent number: 4906241Abstract: Dilation balloon devices that employ a metal tube for introduction of inflation fluid from distal end into a balloon have special features that enable introduction through very small passages. A distal core wire is shown forming part of a guide wire extending into the distal end of the tube. The core wire is fixed at the distal end of the tube, and has a proximal extension bridging across a fluid opening formed in the wall of the tube. The wire extension serves to transfer stress from the distal end of the device, across the fluid opening, to adjacent proximal portions of the tube, to prevent stress build-up at the opening that might lead to fracture of the tube during bending. In various embodiments, the device includes a bushing seal at the distal end of the balloon; a helical coil surrounds part or all of the length of the device, with strategic tapers along its length; a shrink tubing is used rather than a coil; and a pair of cross-wound multifilar coils are employed.Type: GrantFiled: March 18, 1988Date of Patent: March 6, 1990Assignee: Boston Scientific CorporationInventors: Richard A. Noddin, Arthur R. Madenjian, Ralph J. Barry, Jr., Fernando A. de Toledo, Richard M. DeMello
