Publication number: 20230078390Abstract: Medical adhesive articles include a layer of adhesive and a modified substrate layer where the layer has a plurality of cuts arrayed in a pattern that may be random or the pattern can be arrayed along at least one axis. The cuts are gaps, but the gaps are not visible to the naked eye when the adhesive article is in an unstressed state, and at least some of the cuts become gaps that are visible to the naked eye and form apertures when the adhesive article is in a stressed state. The adhesive articles can be used to adhere a medical device to skin.Type: ApplicationFiled: March 29, 2021Publication date: March 16, 2023Inventors: Audrey A. Sherman, Del R. Lawson, Anne C.F. Gold, Silvia G.B. Guttmann, Thomas R.J. Corrigan, Carole Sedlock, Corey D. Voelker

Patent number: 6126528Abstract: The present invention provides novel preformed base blocks that may be used with thermoplastic ophthalmic lens blocking compositions. The preformed base block has a rear portion that is sized and adapted to fit the chuck of a lens processing machine and a front portion that has a textured front surface and preferably a negatively tapered peripheral edge. The front portion is adapted to mechanically retain the thermoplastic blocking composition to form a lens block against a lens blank.Type: GrantFiled: September 3, 1997Date of Patent: October 3, 2000Assignee: 3M Innovative Properties CompanyInventor: Carole Sedlock

Patent number: 6107366Abstract: The present invention provides thermoplastic ophthalmic lens blocking compositions that have many advantages over traditional metal alloy materials. Preferred compositions comprise a blend of a homopolymer or copolymer of epsilon-caprolactone with a modifier selected from the group consisting of carboxylic; straight chain monohydric alcohols; branched chain monohydric alcohols; polyethylene glycols; and polyethylene glycol ethers. The composition may also comprise one or more fillers or heat absorbing materials. In one embodiment, the composition is used to fill the cavity between a preformed lens block and a lens. In another embodiment the composition is used to form a lens block. Methods of holding a lens blank are taught. Tapes that provide a receptive surface against which the composition may be adhered are disclosed.Type: GrantFiled: April 7, 1998Date of Patent: August 22, 2000Assignee: 3M Innovative Properties CompanyInventors: Sharon R. Benjamin, Michael Govek, John H. Ko, Joel D. Oxman, Carole Sedlock, F. Andrew Ubel, Todd R. Williams

Patent number: 6036313Abstract: The present invention provides thermoplastic ophthalmic lens blocking compositions that have many advantages over traditional metal alloy materials. Preferred compositions comprise a homopolymer or copolymer of epsilon-caprolactone, have a number average molecular weight between 3,000 and 100,000, and a polydispersity less than 10. The composition may also comprise one or more modifiers, fillers or heat absorbing materials. In one embodiment, the composition is used to fill the cavity between a preformed lens block and a lens. In another embodiment the composition is used to form a lens block. Methods of holding a lens blank are taught. Tapes that provide a receptive surface against which the composition may be adhered are disclosed.Type: GrantFiled: May 6, 1998Date of Patent: March 14, 2000Assignee: 3M Innovative Properties CompanyInventors: Sharon R. Benjamin, Michael Govek, Patrick D. Hyde, John H. Ko, Philip G. Martin, Joel D. Oxman, William L. Parish, Jr., Carole Sedlock, Richard L. Severance, F. Andrew Ubel, Todd R. Williams

Patent number: 5885700Abstract: The present invention provides thermoplastic ophthalmic lens blocking compositions that have many advantages over traditional metal alloy materials. Preferred compositions comprise a blend of (i) a hydrocarbon resin, preferably an aromatic hydrocarbon resin; (ii) a side chain crystallizable hydrocarbon polymer or copolymer; and (iii) optionally an modifier or mixture of modifiers, preferably straight chain alcohols. The composition may also comprise one or more modifiers, fillers or heat absorbing materials. In one embodiment, the composition is used to fill the cavity between a preformed lens block and a lens. In another embodiment the composition is used to form a lens block. Methods of holding a lens blank are taught. Tapes that provide a receptive surface against which the composition may be adhered are disclosed.Type: GrantFiled: March 17, 1997Date of Patent: March 23, 1999Assignee: Minnesota Mining and Manufacturing CompanyInventors: James A. Weldon, Michael Govek, Carole Sedlock, John H. Ko

Patent number: 5827390Abstract: The present invention provides methods of holding ophthalmic lens blanks using thermoplastic lens blocking compositions. Preferred compositions either comprise a homopolymer or copolymer of epsilon-caprolactone, have a number average molecular weight between 3,000 and 100,000, or have a polydispersity less than 10. The composition may also comprise one or more modifiers, fillers or heat absorbing materials. In one method, the composition is injected into the cavity between a preformed lens block and a lens. In another method, the surface of a lens block comprising the thermoplastic lens blocking composition is heated and formed against the lens blank. Tapes that provide a receptive surface against which the composition may be adhered are disclosed.Type: GrantFiled: September 13, 1996Date of Patent: October 27, 1998Assignee: Minnesota Mining and Manufacturing CompanyInventors: Sharon R. Benjamin, Michael Govek, Patrick D. Hyde, John H. Ko, Philip G. Martin, Joel D. Oxman, William L. Parish, Jr., Carole Sedlock, Richard L. Severance, F. Andrew Ubel, Todd R. Williams
