Patent number: 7520893Abstract: A graftless prosthetic stent for treatment of vascular lesions such as aneurysms and arterio-venous fistulas, especially in neurovascular vessels, comprises a continuous helical ribbon formed of a shape-retaining metal having a transition temperature at which the stent expands from its contracted condition to a radially expanded condition, the stent remaining substantially cylindrical in its contracted and expanded conditions. The helical windings have variable width, thickness, number or size of openings, or combinations of these features, which affect the stiffness, rate of expansion at the transition temperature, and the area of vessel wall covered by the stent. A catheter device which includes the stent, and a method of treatment using the stent are also provided.Type: GrantFiled: March 1, 2005Date of Patent: April 21, 2009Assignee: Scimed Life Systems, Inc.Inventor: Patrick Rivelli, Jr.

Publication number: 20090005637Abstract: According to the present state of the art, endoscopic cannulation of the common bile duct and papillotomy and/or sphincterotomy of the Papilla of Vater and/or the Sphincter of Oddi is accomplished by advancing a sphincterotome (or papillotome or cannulotome) into an endoscope/duodenoscope so that the distal tip of the sphincterotome exits the endoscope adjacent the sphincter muscles at the Papilla of Vater. The endoscope mechanisms are then manipulated to orient the distal tip of the sphincterotome to the desired position for proper cannulation of the duct. Accurate and consistent control of the length of the exposed blade is made difficult due to a number of factors. These factors include: 1) differences in the inside diameters of the outer tube and the needle knife wire, 2) the orientation of the needle knife wire within the outer tube, 3) the mismatch of tolerance of the needle knife wire and the inside diameter of the extrusion, 4) anatomy, and 5) endoscope manipulation.Type: ApplicationFiled: June 27, 2008Publication date: January 1, 2009Applicant: Scimed Life Systems, Inc.Inventors: Yem Chin, John Griego

Publication number: 20080281191Abstract: An improved method of tracking a catheter's position within a human body does not rely on x-rays, but instead calculates the position of the catheter's imaging head by analyzing image data. Such an analysis is able to determine the position of the imaging head in 3 dimensional space, relative to an arbitrarily selected reference image. An image is compared with the reference image, correlation data between corresponding points on the two images are gathered, and a correlation loss rate in a particular direction is determined. This correlation loss rate is modeled to an exponential function, which is evaluated to estimate an angle of separation between the image and the reference image. One or more angles of separation are used to determine a position in three dimensional space of the image, relative to the reference image. By repeating this process for a series of images being gathered by a catheter, the position of the catheter can be determined.Type: ApplicationFiled: July 21, 2008Publication date: November 13, 2008Applicant: SciMed Life Systems, Inc.Inventor: Shashidhar Sathyanarayana

Publication number: 20080269561Abstract: An endoscopic imaging system includes a reusable control cabinet having a number of actuators that control the orientation of a lightweight endoscope that is connectable thereto. The endoscope is used with a single patient and is then disposed. The endoscope includes an illumination mechanism, an image sensor and an elongate shaft having one or more lumens located therein. A polymeric articulation joint at the distal end of the endoscope allows the distal end to be oriented by the control cabinet. The endoscope is coated with a hydrophilic coating that reduces its coefficient of friction and because it is lightweight, requires less force to advance it to a desired location within a patient.Type: ApplicationFiled: April 28, 2008Publication date: October 30, 2008Applicant: SCIMED LIFE SYSTEMS, INC.Inventors: Michael S. Banik, Dennis R. Boulais, Lucien Alfred Couvillon, Albert C.C. Chin, Ian W. Hunter

Patent number: 7442384Abstract: Crosslinked compositions formed from water-insoluble copolymers are disclosed. These compositions are copolymers having a bioresorbable region, a hydrophilic region and at least two cross-linkable functional groups per polymer chain. Crosslinking of these polymers can be effected in solution in organic solvents or in solvent-free systems. If crosslinking occurs in a humid environment, a hydrogel will form. If crosslinking occurs in a non-humid environment, a xerogel will form which will form a hydrogel when exposed to a humid environment and the resulting crosslinked materials form hydrogels when exposed to humid environments. These hydrogels are useful as components in medical devices such as implantable prostheses. In addition, such hydrogels are useful as delivery vehicles for therapeutic agents and as scaffolding for tissue engineering applications.Type: GrantFiled: September 19, 2006Date of Patent: October 28, 2008Assignee: Scimed Life Systems, Inc.Inventors: Gary L. Loomis, D. Christian Lentz

Patent number: 7425291Abstract: The present invention provides an apparatus and method for manufacturing polymeric thin-walled tubular members, which are well-suited for use as vascular grafts. The apparatus of the present invention enables extrusion of a tubular member having an extremely thin wall thickness so as to facilitate passage through tortuous vascular passageways. The apparatus achieves uniform wall thickness in a tubular member by establishing and maintaining axial alignment of a ram having a concentrically disposed guide rod therein with a die supported in concentric relation to the guide rod.Type: GrantFiled: September 22, 2004Date of Patent: September 16, 2008Assignee: Scimed Life Systems, Inc.Inventors: James Venditti, Howard Wolek, Alice Wong, David J.
