Bioabsorbable Materials And Medical Devices Made Therefrom

View page
US Patent:
6716957, Apr 6, 2004
Filed:
Jan 8, 2001
Appl. No.:
09/756589
Inventors:
Deger C. Tunc - East Brunswick NJ
Assignee:
Stryker Technologies Corporation - Kalamazoo MI
International Classification:
C08G 6308
US Classification:
528354, 525462, 525461, 525413, 525415, 525469, 606 77, 606 73, 606154, 623 2375
Abstract:
A bioabsorbable material such as a terpolymer of poly-(L-lactide/D-lactide/glycolide). The material may consist of 85 molar percent L-lactide, 5 molar percent D-lactide, and 10 molar percent glycolide. The material may have a heat of fusion of about 15-25 J/G, tensile strength retention at 26 weeks of incubation of at least about 50%, and tensile strength retention at 52 weeks of incubation of at most about 25%. The material may be used in implantable devices such as bone fixation devices.

Process For Forming Bioabsorbable Implants

View page
US Patent:
6719935, Apr 13, 2004
Filed:
Jan 5, 2001
Appl. No.:
09/754935
Inventors:
Deger Tunc - East Brunswick NJ
Assignee:
Howmedica Osteonics Corp. - Allendale NJ
International Classification:
B29C 4778
US Classification:
264 407, 264178 R, 2642356, 264342 RE
Abstract:
A process for forming a rod of bioabsorbable polymeric material includes extruding the material at a temperature above its melting point at a controlled rate of between 0. 4 to 20 feet per minute to form a continuous rod. The continuous rod is then cooled by passing the rod through a cooling bath to cause nucleation. The continuous rod is passed through a first puller running at least at the same speed as the extruder. A second puller is provided which is moving faster than the first puller so that the continuous rod is elongated at a ratio of between 2 and 12 times. During this elongation, the rod is heated to a temperature of between 55Â C. and 140Â C. in an oven located between the first and second pullers. The rod is annealed at a temperature of between 70Â C. and 110Â C.

US Patent:
20020004660, Jan 10, 2002
Filed:
Feb 23, 2001
Appl. No.:
09/791357
Inventors:
Bruce Henniges - Kalamazoo MI, US
Paul Longo - Kalamazoo MI, US
Jon Ahola - Freiburg, DE
Douglas Tyler - Paw Paw MI, US
Mark Wasserman - Delton MI, US
Mark Salzberger - Portage MI, US
Deger Tunc - East Brunswick NJ, US
Robert Landeryou - Kalamazoo MI, US

Peter Forst - Emmendingen, DE
Assignee:
Stryker Instruments
International Classification:
A61B017/56
US Classification:
606/069000
Abstract:
The present invention is a system for installing bioabsorbable plates for general bone repair, as for example, facial or cranial osteosynthesis. The present invention includes an improved plate and fastener system which reduces if not eliminates stresses within the plate. It also includes an improved fastener container and driver for handling and installing fasteners. The system employs a unique water bath for heating the bioabsorbable plate so they can be deformed to the contours of the bone being repaired. Additionally, there is a hand tool for localized heating and deformation of the plate when positioned against the bone to further ensure conformity with the bone structure. These and other features are contained within a kit which is easily sterilized.

Prosthesis With Sustained Release Analgesic

US Patent:
20040180072, Sep 16, 2004
Filed:
Mar 12, 2003
Appl. No.:
10/387315
Inventors:
Deger Tunc - East Brunswick NJ, US
Chitranjan Ranawat - Alpine NJ, US
Amar Ranawat - New York NY, US
James Banks - Ho Ho Kus NJ, US
Assignee:
Howmedica Osteonics Corp. - Allendale NJ
International Classification:
A61K031/704
A61K031/545
A61K031/65
US Classification:
424/423000, 514/037000, 514/304000, 514/152000, 514/200000
Abstract:
A device for releasing a therapeutic agent in the body space in the form of a prosthetic joint implant having a first portion such as a stemmed portion for contacting bone tissue in an intramedullary canal of a long bone. The implant has a second portion which extends into the body space such as a joint space. The joint component contains a reservoir filled with a bioabsorbable/resorbable polymer which includes a therapeutic agent. The reservoir is open or in contact with the joint space as the body fluid diffuses in and out of the polymeric device it carries the drug into the joint space.

US Patent:
20070191963, Aug 16, 2007
Filed:
Jan 19, 2007
Appl. No.:
11/625119
Inventors:
John Winterbottom - Jackson NJ, US
David Kaes - Toms River NJ, US
Deger Tunc - East Brunswick NJ, US
Todd Boyce - Matawan NJ, US
David Knaack - Summit NJ, US

International Classification:
A61F 2/28
US Classification:
623023500, 623023510, 623023750
Abstract:
An osteoimplant composite comprising a plurality of particles of an inorganic material, a bone substitute material, a bone-derived material, or any combination thereof; and a polymer material with which the particles are combined. The composite is either naturally moldable or flowable, or it can be made moldable or settable. After implantation, the composite may be set to provide mechanical strength to the implant. The inventive composite have the advantage of being able to fill irregularly shape implantation site while at the same time being settable to provide the mechanical strength required for most orthopedic applications. The invention also provides methods of using and preparing the moldable and flowable composites.

Process For Preparation Of Alkali Cellulose Ester Sulfates

View page
US Patent:
40052516, Jan 25, 1977
Filed:
Feb 20, 1975
Appl. No.:
5/551570
Inventors:
Deger C. Tunc - East Brunswick NJ
Assignee:
Johnson & Johnson - New Brunswick NJ
International Classification:
C08B 700
US Classification:
536 59
Abstract:
A barrier film is provided for a product used in contact with body fluids. The barrier film comprises an alkali salt of a sulfated cellulose ester, with a degree of sulfate substitution satisfactory to render the film resistant to body fluids and yet dispersible in low salt concentration aqueous solutions such as those found in a household water closet. There is also disclosed a process for preparing alkali salts of sulfated cellulose esters comprising sulfating woodpulp, acylating the sulfated wood pulp, and precipitating the desired product in an aqueous precipitation medium maintained at a specified pH range.
