Patent number: 6802858Abstract: Implants and associated delivery systems for promoting angiogenesis in ischemic tissue are provided. The implants may be delivered percutaneously, thoracically or surgically and are particularly well suited for implantation into the myocardium of the heart. The implants are configured to have a first configuration having a low profile and an expanded, second configuration having a large profile. The implants are delivered to the ischemic tissue location in the first configuration, implanted then expanded to the second configuration. The expanded implants maintain a stress on the surrounding tissue, irritating and slightly injuring the tissue to provoke an injury response that results in angiogenesis. The flow of blood from the surrounding tissue into the implant and pooling of the blood in and around the implant leads to thrombosis and fibrin growth. This healing process leads to angiogenesis in the tissue surrounding the implant.Type: GrantFiled: January 31, 2001Date of Patent: October 12, 2004Assignee: C.R. Bard, Inc.Inventors: Richard A.

Publication number: 20040186587Abstract: The present invention provides devices and methods for treating biological tissue. The treatment comprise implanting a scaffold implant device into in combination with a therapeutic material such as cells, tissue or cell components. The scaffold device serves to hold the therapeutic material at the treatment site, protecting it from being squeezed out by surrounding tissue. Additionally the scaffold device is believed to trigger an injury response that leads to angiogenesis in the tissue, which provides blood flow and nutrients to the associated therapeutic material to sustain it for a therapeutically effective amount of time. The devices may also be implanted at a tissue site already treated with a therapeutic material to initiate angiogenesis at the treatment site to sustain the material. The devices and methods also may be used to treat tumors with a necrosis factor.Type: ApplicationFiled: January 28, 2004Publication date: September 23, 2004Applicant: C.R. Bard, Inc.Inventor: John E.

Patent number: 6733488Abstract: The present invention provides a transthoracic drug delivery device that utilizes pressure to determine the precise location of the distal tip of the delivery tube of the device to insure that therapeutic substances are ejected into the myocardium and not dissipated in unintended tissue locations. In one embodiment the drug delivery device comprises a pressure sensing tube mounted in parallel to a drug delivery tube wherein the tubes are staggered so that the pressure tube extends beyond the delivery tube. When the myocardium is penetrated by the tubes, advancement into the heart and penetration into the left ventricle by the pressure sensing tube results in a pressure increase that indicates to the physician that the drug delivery tube, by its placement relative to the pressure sensing tube is still in the myocardium and, thus, prepared to deliver the drug.Type: GrantFiled: December 5, 2002Date of Patent: May 11, 2004Assignee: C.R.
