Patent number: 8729246Abstract: The present invention provides a composition for selectively delivering an active agent to a portion of an organism. The composition comprises first and second polymer portions, having first and second functional groups attached as a side-chain thereto, respectively. The first and second functional groups form cross-links between the first and second polymer portions. The cross-links are capable of being broken by a substance of the organism, thereby resulting in release of the active agent. The composition provides a novel means for controlling the selective release of the active agent in the organism.Type: GrantFiled: August 10, 2012Date of Patent: May 20, 2014Assignees: Alcatel Lucent, Rutgers, The State University of New JerseyInventors: Noshir A. Langrana, David C. Lin, Bernard Yurke

Patent number: 5900207Abstract: A fused deposition process is used to form three-dimensional solid objects from a mixture including a particulate composition dispersed in a binder. The article is formed by depositing the mixture in repeated layers of predefined thickness, with each layer solidifying before the next adjacent layer is dispensed. Following formation and a binder removal step, the article may be at least partially densified to achieve preselected properties. The process permits three-dimensional articles to be formed relatively quickly and inexpensively, without the need for molds or other tooling.Type: GrantFiled: May 20, 1997Date of Patent: May 4, 1999Assignees: Rutgers, the State University Old Queens, Stratasys, Inc.Inventors: Stephen C. Danforth, Mukesh Agarwala, Amit Bandyopadghyay, Noshir Langrana, Vikram R. Jamalabad, Ahmad Safari, Remco van Weeren, William R. Priedeman, Jr.

Patent number: 5545229Abstract: The construction and manufacturing technique for a functional biocompatible intervertebral disc spacer is described. This device is useful for a replacement for a degenerated disc in certain treatments of back pain and spinal disease. The disc spacer possesses mechanical properties akin to those of the normal disc and will preserve normal functions of the spinal motion segment. The device achieves the desired properties by varying the hardness of the elastomeric material in its nucleus and annulus.Type: GrantFiled: July 28, 1993Date of Patent: August 13, 1996Assignees: University of Medicine and Dentistry of NJ, Rutgers UniversityInventors: John R. Parsons, Casey K. Lee, Noshir A. Langrana, Alastair J. Clemow, Elizabeth H. Chen, Monica V. Hawkins

Patent number: 5429140Abstract: A rehabilitation system employs a force feedback system, such as a force feedback glove, to simulate virtual deformable objects. Prior to rehabilitation, the patient places his or her hand in a sensing glove which measures the force exertable by the patient's digits. Information from the sensing glove is received by an interface and transmitted to a computer where the information can be used to diagnose the patient's manual capability. The computer generates rehabilitation control signals for a force feedback glove. The patient places his or her hand in the force feedback glove and attempts to bring the digits together as though grasping the virtual object. The force feedback glove resists the squeezing movement of the digits in a manner that simulates the tactile feel of the virtual object. The force exerted by the fingers of the patient is fed back to the computer control system where it can be recorded and/or used to modify future rehabilitation control signals.Type: GrantFiled: June 4, 1993Date of Patent: July 4, 1995Assignees: Greenleaf Medical Systems, Inc., Grigore C.

Patent number: 4911718Abstract: The construction and manufacturing technique for a functional biocompatible intervertebral disc spacer is described. This device is useful for a replacement for a degenerated disc in certain treatments of back pain and spinal disease. The disc spacer possesses mechanical properties akin to those of the normal disc and will preserve normal functions of the spinal motion segment. The device achieves the desired properties by providing reinforcing fibers of appropriate orientation and number within an elastomeric matrix.Type: GrantFiled: June 10, 1988Date of Patent: March 27, 1990Assignees: University of Medicine & Dentistry of N.J., Rutgers University, Johnson & JohnsonInventors: Casey K.
