  • Publication number: 20070225748
    Abstract: In accordance with the present invention, a distal protection and embolic material retrieval device with improved apposition to both large and small vessel walls of varying geometries for enhancing the filtering of embolic material during intravascular procedures while allowing for the passage of blood is provided. The device includes a filter basket designed to maximize apposition of the filtering portion to that of the vessel wall and may include struts which provide circumferential support to the filtering membrane and thereby minimizing or eliminating in-folding of the filter basket. Thin film materials may also be utilized for the filtering membrane of the filter basket. In addition one can incorporate biological and/or pharmaceutical agents in combination with the present invention.

  • Publication number: 20070173685
    Abstract: A method of implanting a surgically implantable band, the method comprising the steps of providing a band with an elongated body member having a first end with a first latching member positioned thereon, and a second end with a second latching member positioned thereon. The first latching member has a suture tab extender extending therefrom. The suture tab extender has a suture attached thereto. The second end has a gripping section positioned thereon shaped and dimensioned to facilitate gripping as the gastric band extender is passed through the second latching member. The method further includes the step of positioning the band around an anatomical structure and latching the band around the structure by placing the suture tab extender through the second latching member and thereafter coupling the first and second latching members. The method further involves the step of removing the suture tab extender from the band.

  • Publication number: 20070106364
    Abstract: An intraluminal medical device delivery system that distributes forces more uniformly across an intraluminal medical device during loading and delivery of the device to an intended treatment site. A support member provided on an inner member of a catheter delivery system helps to more uniformly distribute forces across the device by crimping the device over the support member so as to place the support member in a mechanically compressed state during delivery of the device to the intended treatment site. The support member is preferably comprised of a material having a modulus of elasticity that increases when the material is compressed. The mechanical nature of the support member provides increased stability to the device during loading and delivery thereof without providing heat or other preformed or additional mechanical members to the support member. Repositioning of the device is available due to the stability of the device when mounted on the support member.

  • Publication number: 20070016229
    Abstract: A removable suture tab extender for a gastric band is shaped and dimensioned for selective attachment to a first end of the gastric band, the gastric band including a latching mechanism composed of a first latching member positioned at the first end of the gastric band and a second latching member positioned at a second end of the gastric band. The gastric band extender includes an elongated body member having a first end and a second end. The first end of the elongated body member is shaped and dimensioned for coupling with the first latching member. The second end of the elongated body member includes a gripping section shaped and dimensioned to facilitate gripping thereof as the gastric band extender is passed through the second latching member.

  • Publication number: 20050079365
    Abstract: Disclosed is a method for modifying the surface properties of a silicone or siloxane-based polymer or copolymer substrate comprising, (1) exposing the surface to a basic aqueous resolution comprising a substance capable of graft-polymerization with the silicone or siloxane-based polymer or copolymer substrate, the aqueous solution having a pH above about 8.0, the exposure to the basic aqueous solution being for a time sufficient to enhance the graft-polymerization and (2) subjecting the surface and basic solution to conditions whereby the polymerizable substance is polymerized to form a graft-polymerized coating on the surface. Also disclosed are compositions of matter prepared by the above-described process as well as articles manufactured therefrom.

  • Publication number: 20050043789
    Abstract: A device comprising a substrate having a surface for contacting blood wherein the surface has a continuum of thrombus-resistant polymeric material coated on and extending into the substrate to anchor the coating thereon. The device may be prepared by a method comprising: (a) contacting the substrate with a solution of monomer or oligomer in a solvent to wet the surface and impregnate the substrate below the surface to a substantial depth; (b) removing the solvent to form a continuum of the monomer or oligomer on the surface and within the substrate to a substantial depth; and (c) polymerizing the monomer or oligomer to form a substantial continuum of polymer coating on the surface and extending to a substantial depth in the substrate, thereby firmly anchoring the polymer coating on the surface.

  • Publication number: 20050033417
    Abstract: Medical devices, and in particular implantable medical devices, may be coated to minimize or substantially eliminate a biological organism's reaction to the introduction of the medical device to the organism. The medical devices may be coated with any number of biocompatible materials. Therapeutic drugs, agents or compounds may be mixed with the biocompatible materials and affixed to at least a portion of the medical device. These therapeutic drugs, agents or compounds may also further reduce a biological organism's reaction to the introduction of the medical device to the organism. In addition, these therapeutic drugs, agents and/or compounds may be utilized to promote healing, including the formation of blood clots. Also, the devices may be modified to promote endothelialization. Various materials and coating methodologies may be utilized to maintain the drugs, agents or compounds on the medical device until delivered and positioned.
