Patent number: 8662765Abstract: Providing for a wafer level optical system employing composite lenses is disclosed herein. Conventional focus lens assemblies require three or more lenses. By way of example, two composite lenses can be used to reduce the cost of a wafer-level camera. In some aspects, the composite lenses can be aspheric and can employ a broader variety of wafer materials than earlier designs that only operated in narrow ranges of refractive indices and Abbe numbers.Type: GrantFiled: April 18, 2011Date of Patent: March 4, 2014Assignee: DigitalOptics CorporationInventors: Pavel Reshidko, Kai Engelhardt, Ephraim Goldenberg, Michael Dror

Patent number: 7811317Abstract: A method for making an intravascular stent by applying to the body of a stent a solution which includes a solvent, a polymer dissolved in the solvent and a therapeutic substance dispersed in the solvent and then evaporating the solvent. The inclusion of a polymer in intimate contact with a drug on the stent allows the drug to be retained on the stent during expansion of the stent and also controls the administration of drug following implantation. The adhesion of the coating and the rate at which the drug is delivered can be controlled by the selection of an appropriate bioabsorbable or biostable polymer and the ratio of drug to polymer in the solution. By this method, drugs such as dexamethasone can be applied to a stent, retained on a stent during expansion of the stent and elute at a controlled rate.Type: GrantFiled: October 30, 2007Date of Patent: October 12, 2010Assignee: Medtronic, Inc.Inventors: Eric P. Berg, Ronald J. Tuch, Michael Dror, Rodney G. Wolff

Patent number: 5893840Abstract: Balloon catheters are prepared to include body affecting chemicals within microcapsules on the exterior of the balloon either alone or with a stent. The coating releases from the balloon when the balloon is inflated into contact with the lumen to be treated. The device provides accurate placement of the dosage required at the location in need of treatment. A sheath may be employed over the balloon and microcapsules to prevent the microcapsules from being rubbed off during delivery through a body lumen. The catheters are especially useful in balloon angioplasty procedures.Type: GrantFiled: April 24, 1996Date of Patent: April 13, 1999Assignee: Medtronic, Inc.Inventors: Vincent W. Hull, Robert S.

Patent number: 5807471Abstract: A ion selective electrode is formed by an electrode having a first membrane with a diffusion rate selective to heparin or other polyions, and a selective polymeric coating thereon having a polyion diffusion rate lower than the polyion diffusion rate of the first membrane. The electrode is sensitive to solutions containing low polyion concentrations such as low heparin concentrations.Type: GrantFiled: April 30, 1996Date of Patent: September 15, 1998Assignee: Medtronic, Inc.Inventors: Michael Dror, Robert F.

Patent number: 5799384Abstract: A radially expandable stent for implantation within a body lumen having a generally cylindrical body with open proximal and distal ends, the cylindrical body comprising a plurality of metal elements joined to allow flexing of the cylindrical body along the longitudinal axis of the body whereby the stent can conform to a curved body lumen and a polymeric film extending between the metal elements of the stent. The stent provides a biocompatible polymeric surface to contact and support a body lumen and also a flexible structure to allow the stent to conform closely to bends in a body lumen. The stent is especially useful for repairing an injury to blood vessels caused during angioplasty procedures.Type: GrantFiled: October 23, 1996Date of Patent: September 1, 1998Assignee: Medtronic, Inc.Inventors: Robert S.
