Patent number: 6203732Abstract: A generally tubular device (e.g., a stent or catheter) for placement in a lumen of a patient's body is made by forming a depressed pattern in an external surface of a mold. The depressed pattern corresponds to a desired shape of the generally tubular device. A material is deposited in the depressed pattern for the material to form the generally tubular device conforming to the depressed pattern. The generally tubular device is separated from the mold.Type: GrantFiled: July 2, 1998Date of Patent: March 20, 2001Assignee: Intra Therapeutics, Inc.Inventors: Elizabeth A. Clubb, Thomas L.

Patent number: 6107004Abstract: Manufacturing processes for apparatus, including slotted hypotube, for use as a catheter, a guidewire, a catheter sheath for use with catheter introducers or a drug infusion catheter/guidewire are disclosed. The manufacturing process includes creating a pattern of slots or apertures in a flexible metallic tubular member, by processes including but not limited to, electrostatic discharge machining (EDM), chemical milling, ablation and laser cutting. These slots or apertures may be cut completely or partially through the wall of the flexible metallic tubular member. These manufacturing processes may include the additional step of encasing the flexible metallic member such that a fluid tight seal is formed around the periphery of the tubular member.Type: GrantFiled: March 27, 1998Date of Patent: August 22, 2000Assignee: Intra Therapeutics, Inc.Inventor: James V.

Patent number: 5911752Abstract: A method for implanting a stent within a body passageway defined by a body wall. The method includes the step of fabricating the stent in an initial orientation in which the stent has an initial diameter and an initial length. The method also includes the step of collapsing the stent radially inward from the initial orientation to a collapsed orientation in which the stent has a collapsed length and a collapsed diameter. The stent is collapsed by deforming a portion of the stent beyond the elastic limit of the portion of the stent. The method further includes the step of positioning the collapsed stent at a desired location within the body passageway. Additionally, the method includes the step of expanding the stent radially outward from the collapsed orientation to a deployed orientation in which the stent has a deployed diameter and a deployed length. The deployed diameter and the deployed length are respectively substantially equal to the initial diameter and the initial length.Type: GrantFiled: September 13, 1996Date of Patent: June 15, 1999Assignee: IntraTherapeutics, Inc.Inventors: Mark Owen Dustrude, James V.

Patent number: 5815904Abstract: The present invention relates to a method for manufacturing a tubular medical device for insertion in a body. The method includes the step cutting a plurality of cross-sectional pieces or layers from a flat sheet. The pieces are cut so as to define inner apertures. The pieces are then aligned generally along an axis such that the pieces are arranged to form an elongated structure having an interior lumen extending longitudinally therethrough. Finally, the aligned pieces of the elongated structure are connected together such that each interconnected piece forms a layer of the tubular medical device.Type: GrantFiled: March 13, 1997Date of Patent: October 6, 1998Assignee: IntraTherapeutics, Inc.Inventors: Thomas L. Clubb, James V. Donadio, III, Mark O. Dustrude, J. Edward Shapland, II
