| 20110306982 | DISC ANNULUS CLOSURE - Disclosed herein are methods for treating a defect in a spinal disc nuclear space, comprising: (a) creating an opening by open, percutaneous or laparoscopic techniques to access the defect in the nuclear space; (b) removing a desired amount of tissue from the nuclear space; (c) positioning a delivery catheter through the opening; (d) fluidically isolating the nuclear space by blocking the opening with a blocking component of the catheter; (e) delivering an in-situ curable liquid material through a lumen of the catheter to the nuclear space; and (f) maintaining the isolating until the liquid material has cured. Also disclosed are treatment systems and materials for prostheses. | 12-15-2011 |
| 20110105633 | FUNCTIONALIZED STILBENE-POLYALKYLENE OXIDE PREPOLYMERS - Stilbene-polyalkylene oxide prepolymers which include a polyalkylene oxide backbone with two or more isocyanate substituents and at least one hydroxystilbene or methoxystilbene substituent are useful as one component adhesives and biocompatible device coatings. Stilbene-polyalkylene compositions useful as a two component adhesive contain: a) a polyalkylene oxide having two or more amine substituents with b) a stilbene polyisocyanate compound, or alternatively contain: a) a polyethylene oxide having two or more isocyanate substituents with b) a stilbene diamine compound, or, alternatively contain: a) a bioabsorbable group in addition to a stilbene group attached to a polyalkylene backbone and b) a diamine compound. | 05-05-2011 |
| 20110029084 | FOAM PROSTHESIS FOR SPINAL DISC - Disclosed herein are spinal disc implants comprising a foam adapted to completely or partially replace a nucleus pulposus within a spinal disc cavity, the foam being a nonabsorbable, closed cell and having a Poisson ratio of less than 0.5. Also disclosed are methods of implanting a foam, either as an in-situ curable material or as a preformed foam. | 02-03-2011 |
| 20100076486 | DISC ANNULUS CLOSURE - Disclosed herein are methods for treating a defect in a spinal disc nuclear space, comprising: (a) creating an opening by open, percutaneous or laparoscopic techniques to access the defect in the nuclear space; (b) removing a desired amount of tissue from the nuclear space; (c) positioning a delivery catheter through the opening; (d) fluidically isolating the nuclear space by blocking the opening with a blocking component of the catheter; (e) delivering an in-situ curable liquid material through a lumen of the catheter to the nuclear space; and (f) maintaining the isolating until the liquid material has cured. Also disclosed are treatment systems and materials for prostheses. | 03-25-2010 |
| 20090304773 | SURGICAL ADHESIVE AND USES THEREFORE - The present invention provides a liquid polymer composition which can be implanted into a living mammal and which forms a solid hydrogel by in situ polymerization upon contact with body fluid and tissue. The composition also can be used as a coating on a medical device, or for the formation of a medical device. Formation of a solid implant or coating involves crosslinking of the adhesive with itself and with surrounding tissue. The liquid implant, by itself or in conjunction with various prostheses, can be used for many purposed, including fixation of the urethra for providing treatment for incontinence, and repair of herniations in the abdominal cavity, including rectocele, cystocele, enterocele, and inguinal hernia. The adhesive may be used to establish adhesion prevention during such repairs, in part by coating or being the material of a repair mesh. | 12-10-2009 |
| 20090248048 | PROSTHETIC FOR TISSUE REINFORCEMENT - A process for the manufacture of a prosthetic sheet with improved tissue healing characteristics useful in reinforcing tissue defects is disclosed. Generally the prosthetic may be comprised of any material that does not promote fibrosis and inflammation. In particular, the prosthetic may be comprised of non-absorbable hydrogel reinforced with fiber, so that the fiber reinforcement is encapsulated and shielded from interaction with tissue. The prosthetic may contain pores that pass through it to encourage tissue through-growth. These pores may be made by removing material from a sheet of reinforced hydrogel or the reinforcement means may contain a porosity around which the hydrogel is formed and the porosity is maintained. | 10-01-2009 |
| 20090024107 | Disc annulus closure - Disclosed herein are methods for treating a defect in a spinal disc nuclear space, comprising: (a) creating an opening by open, percutaneous or laparoscopic techniques to access the defect in the nuclear space; (b) removing a desired amount of tissue from the nuclear space; (c) positioning a delivery catheter through the opening; (d) fluidically isolating the nuclear space by blocking the opening with a blocking component of the catheter; (e) delivering an in-situ curable liquid material through a lumen of the catheter to the nuclear space; and (f) maintaining the isolating until the liquid material has cured. Also disclosed are treatment systems and materials for prostheses. | 01-22-2009 |
| 20080221628 | DEVICES AND METHODS FOR SPINE REPAIR - Surgical methods of repairing defects and deficiencies in the spine are disclosed. The methods involve delivering a single part in-situ polymerizing fluid to (i) close a weakened segment or fissure in the annulus fibrosus, (ii) strengthen the annulus, (iii) replace or augment the disc nucleus, or (iv) localize a disc prosthesis. The methods may include placing a delivery conduit adjacent to the repair site and providing a liquid tissue adhesive to bond to and repair a disc defect or deficiency | 09-11-2008 |
