Patent number: 9522217Abstract: Therapeutic and drug delivery systems are provided in the form of medical devices with coatings for capturing and immobilizing target cells such as circulating progenitor or genetically-altered mammalian cells in vivo. The genetically-altered cells are transfected with genetic material for expressing a marker gene and a therapeutic gene in a constitutively or controlled manner. The marker gene is a cell membrane antigen not found in circulating cells in the blood stream and therapeutic gene encodes a peptide for the treatment of disease, such as, vascular disease and cancer. The coating on the medical device may be a biocompatible matrix comprising at least one type of ligand, such as antibodies, antibody fragments, other peptides and small molecules, which recognize and bind the target cells. The therapeutic and/or drug delivery systems may be provided with a signal source such as activator molecules for stimulating the modified cells to express and secrete the desired marker and therapeutic gene products.Type: GrantFiled: April 30, 2004Date of Patent: December 20, 2016Assignee: OrbusNeich Medical, Inc.Inventors: Michael J. B. Kutryk, Robert J. Cottone, Jr., Stephen M. Rowland

Patent number: 9072723Abstract: The invention relates to a method for healing blood vessels by stimulating the formation of a confluent endothelial autologous cell layer in vivo on an implantable metallic stent having a lumen and a luminal surface, and an exterior surface. More specifically, the method includes implanting the stent with a coating in a patient in need of thereof; wherein the coating includes one or more layers of a matrix covalently adherent on said luminal and exterior surface of said stent containing one or more pharmaceutical substances on said exterior surface and a therapeutically effective amount of a single type of antibody, antibody fragments or combinations thereof being compatible to binding selectively to a specific cell surface antigen of circulating autologous endothelial progenitor cells in peripheral blood. In addition, genetically engineered endothelial progenitor cells can be captured on said luminal surface of stent in vivo, to proliferate to form rapidly a confluent endothelium in situ.Type: GrantFiled: August 20, 2012Date of Patent: July 7, 2015Assignee: ORBUS MEDICAL TECHNOLOGY INCInventors: Michael John Bradley Kutryk, Robert J.

Patent number: 6027528Abstract: An endoprosthesis includes a body structure formed of a biocompatible material, the body structure including a first material having an average atomic number greater than 24 and a second material that is different than the first material. The body structure has a mass absorption coefficient effective to provide a ratio of an intensity of an incident X-ray to an intensity of a transmitted X-ray in a range of 1e.sup.-2 to 1e.sup.-4. The endoprosthesis may have a yield strength not greater than 100,000 psi. The endoprosthesis may be in the form of a wire or a tube. In one embodiment the first material is present in an amount not greater than 9% by volume based on the combined volume of the first and second materials. In another embodiment, about 30 to about 40% by volume of the first material is present based on a combined volume of the first and second materials in an endoprosthesis of tubular form.Type: GrantFiled: March 30, 1998Date of Patent: February 22, 2000Assignee: Cordis CorporationInventors: Charles V.

Patent number: 5824043Abstract: An endoprosthesis is provided which includes a stent component and a graft component capturing a portion of the stent component. The stent component is made of generally malleable material arranged to provide the stent component with a collapsed transluminal positioning configuration and an expanded, deployed configuration. The stent component has adjacent end windings that are welded together. In a preferred arrangement, a plurality of these welds define a spine-like welded arrangement, and a number of these arrangements are positioned generally circumferentially around the ends of the stent component. The graft component extends generally between the welded end portions of the stent component, with limited overlap being possible. Also provided is a method for forming this endoprosthesis and a procedure by which the endoprosthesis is implanted by deployment with a suitable expansion device.Type: GrantFiled: May 23, 1996Date of Patent: October 20, 1998Assignee: Cordis CorporationInventor: Robert J.

Patent number: 5251638Abstract: A biopsy forceps device is presented herein which employs a forceps assembly having a pair of forceps connected to the distal end of a control wire having its proximal end extending into a hub. A control wire actuator is connected to the proximal end of the control wire and the actuator is slidably mounted to the hub for slidable movement relative thereto between proximal and distal positions for respectively causing the forceps to be in a closed condition and in an open condition. A releasable locking mechanism normally blocks forward slidable movement of the actuator to prevent the forceps from being actuated to an open condition. A release mechanism releases the locking means from blocking forward movement of the actuator to thereby permit forward movement of the actuator causing the forceps to be actuated to an open condition.Type: GrantFiled: April 16, 1992Date of Patent: October 12, 1993Assignee: Cordis CorporationInventors: Robert J.

Patent number: 5250073Abstract: A biopsy forceps device is provided exhibiting improved torqueable and formable characteristics. The device includes a handle and a core wire connected at its proximal end to the handle and connected at its distal end to a forceps assembly. The control wire displacing device is carried by the handle and serves to displace the core wire for moving the core wire between a forceps open position and a forceps closed position. The core wire includes at least three elongated portions including a proximal portion having a proximal end secured to the wire displacing means, a distal portion having a distal end secured to the forceps assembly and an intermediate portion located between the proximal and distal portions. The proximal portion is of greater length than either the intermediate or distal portions and is of greater diameter than the intermediate portion which, in turn, is of greater diameter than the distal portion.Type: GrantFiled: June 10, 1992Date of Patent: October 5, 1993Assignee: Cordis CorporationInventor: Robert J.

Patent number: 5184625Abstract: A biopsy forceps device is presented herein wherein an elongated flexible hollow body portion having a lumen extending therethrough is provided with proximal and distal ends. A forceps assembly is coupled to the distal end of the body portion and the assembly includes a pair of forceps. A control wire having proximal and distal ends extends through the lumen of the body portion and is coupled at its proximal end to a handle and at its distal end to a forceps assembly. A trigger is mounted to the handle for slidable movement relative thereto between a proximal position and a distal position. A gripping device grips the proximal end of the control wire and is movable between first and second positions for respectively moving the control wire between a forceps open condition and a forceps closed condition. The gripping device is resiliently biased toward its first position. The lever arm engages and moves the gripping device from its first position to its second position against the resilient forces.Type: GrantFiled: April 16, 1992Date of Patent: February 9, 1993Assignee: Cordis CorporationInventors: Robert J.
