Publication number: 20120004718Abstract: A platinum enhanced radiopaque alloy particularly suitable for manufacture of implantable and/or intravascular medical devices. A stent is one preferred medical device which is a generally tubular structure that is expandable upon implantation in a vessel lumen to maintain flow therethrough. The stent is formed from the alloy which has improved radiopacity relative to present utilized stainless steel alloys. This alloy preferably contains from about 2 wt. % to about 50 wt. % platinum; from about 11 wt. % to about 18 wt. % chromium; about 5 wt. % to about 12 wt. % nickel and at least about 15 wt. % iron.Type: ApplicationFiled: November 29, 2010Publication date: January 5, 2012Applicant: BOSTON SCIENTIFIC SCIMED, INC.Inventors: Charles H.

Patent number: 7879005Abstract: A device for collapsing a balloon in the vasculature of a patient after an angioplasty procedure includes a balloon and at least one elastomeric member that is attached to the inner surface of the balloon at a plurality of attachment points. Preferably, the elastomeric member is an annular band that will stretch during balloon inflation. Consequently, when the balloon is deflated, the elastomeric member pulls on the balloon at its attachment points to return the balloon to a predetermined configuration, wherein the balloon collapses inwardly onto itself for subsequent removal of the balloon from the vessel.Type: GrantFiled: March 9, 2007Date of Patent: February 1, 2011Assignee: Boston Scientific Scimed, Inc.Inventors: Show-Mean Wu, Herbert R.

Patent number: 7172609Abstract: A device for incising a stenosis in the vasculature of a patient includes a plurality of blades mounted on a resilient base member. The blades are arranged in a pattern to allow for relative movement between adjacent blades. Specifically, at least one end portion of each blade is juxtaposed with an end portion of the next closest blade. The base member includes a first end affixed to a catheter at a location proximal to an inflatable balloon and a second end affixed to the catheter at a location distal to the inflatable balloon. When the balloon is inserted into the vasculature of a patient, positioned across a stenosis and subsequently inflated, the individually moveable blades form an effective cutting edge that conforms to the surface of the stenosis to effectively allow the stenosis to be incised to a substantially uniform depth.Type: GrantFiled: October 10, 2003Date of Patent: February 6, 2007Assignee: Boston Scientific Scimed, Inc.Inventor: Herbert R.

The blades are arranged in a pattern to allow for relative movement between adjacent blades. Specifically, at least one end portion of each blade is juxtaposed with an end portion of the next closest blade. The base member, in turn, is mounted on the external surface of an inflatable angioplasty balloon. When the balloon is inserted into the vasculature of a patient, positioned across a stenosis and subsequently inflated, the individually moveable blades form an effective cutting edge that conforms to the surface of the stenosis to effectively allow the stenosis to be incised to a substantially uniform depth.Type: GrantFiled: August 5, 2003Date of Patent: March 14, 2006Assignee: Scimed Life Systems, Inc.Inventor: Herbert R.

Patent number: 6730107Abstract: A single lumen rapid-exchange catheter includes a distal sealing port and a proximal sealing port both dimensioned for receiving a guidewire to establish a fluid-tight seal therewith. Each tubular shaped sealing port has a length, and a diameter, and is made of a hydrophilic polymer. In operation, the guidewire is inserted through the distal sealing port and exits from the catheter tube at the shoulder of the catheter tube and through the proximal sealing port. When fluid is present, each sealing port will enlarge to establish a fluid-tight seal with the guidewire. A diverter can be disposed at the proximal sealing port to redirect the guidewire from the lumen and out of the catheter tube through the proximal sealing port.Type: GrantFiled: August 23, 2001Date of Patent: May 4, 2004Assignee: SciMed Life Systems, Inc.Inventors: Gregory S.

Patent number: 6296651Abstract: The present invention is a device and a method for boring a perfusion channel from a coronary artery into a cardiac muscle of a patient. Structurally, the present invention includes a positioning catheter, anchor means and a cutting catheter. The cutting catheter includes a plurality of blades and is advanceable through a deployment lumen of the positioning catheter. Advancement of the cutting catheter through the deployment lumen causes a distal end of the cutting catheter to project laterally from the positioning catheter. In use, the positioning catheter is positioned within the coronary artery. The anchor means is then expanded to anchor the positioning catheter within the artery. The cutting catheter is then advanced through the deployment lumen to bore one or more perfusion channels in the myocardial tissue.Type: GrantFiled: March 7, 2000Date of Patent: October 2, 2001Assignee: Interventional Technologies, Inc.Inventors: Banning Gray Lary, Herbert R.

Patent number: 5800450Abstract: The present invention is a device and a method for boring a perfusion channel into the myocardial tissue of a patient. Structurally, the present invention includes a positioning catheter and a cutting catheter. The positioning catheter is formed with an inflation lumen and a deployment lumen and has an inflatable balloon mounted at its distal end. The cutting catheter has a sharpened distal end and is advanceable through the deployment lumen of the positioning catheter. Advancement of the cutting catheter through the deployment lumen causes the distal end of the cutting catheter to be directed radially outward from the positioning catheter. In use, the positioning catheter is positioned within a target vessel. The inflatable balloon is then expanded to anchor the distal end of the positioning catheter.Type: GrantFiled: October 3, 1996Date of Patent: September 1, 1998Assignee: InterVentional Technologies Inc.Inventors: Banning Gray Lary, Herbert R.

Patent number: 5746968Abstract: A method of manufacturing polymeric material having enhanced structural integrity includes heating the material to a temperature between the material's glass transition temperature and the material's melt temperature. Once heated, the material is highly overstretched in a first direction and moderately overstretched in a second direction. The material is then held in the overstretched condition while it is allowed to cool to room temperature. Cooling is followed by reheating to a curing temperature. After curing for a predetermined period, the material is again allowed to cool. The completed material has high polymeric orientation in the first direction and moderate polymeric orientation in the second direction. Therefore, the material is characterized by enhanced structural integrity and absence of pinhole defects common to highly oriented polymeric materials.Type: GrantFiled: April 12, 1996Date of Patent: May 5, 1998Assignee: Interventional Technologies, Inc.Inventor: Herbert R.
