Patent number: 10751208Abstract: An implant delivery system includes a delivery catheter and a delivery mechanism slidably disposed in a lumen of the delivery catheter. The delivery mechanism includes an annular channel and a compressible annular bushing disposed within the annular channel. The annular bushing is configured for being placed between a compressive profile and an expanded profile. The implant delivery system further includes an implant coaxially disposed between the delivery catheter and the delivery mechanism. The delivery catheter lumen is sized to maintain an engagement element of the implant within the annular channel and to urge the annular bushing into the compressive profile.

Publication number: 20090143786Abstract: Electrolytically detachable implantable devices and methods of delivering the same to a treatment site. An assembly includes an implantable device, such as a vaso-occlusive coil, a conductive deployment mechanism, such as a conductive pusher or wire, and a temporary connection between the deployment mechanism and the coil in the form of an electrolytically detachable junction. The detachable junction includes fine wires, e.g., stainless steel wires having a small diameter of about 0.00001? to about 0.0025?, for example, about 0.0005?. The pusher or wire is used to deliver the implantable device through a catheter and to a desired location or treatment site. After the implantable device is properly positioned, electrical current is applied to the fine wires, thereby simultaneously disintegrating the fine wires and leaving the coil at the treatment site.Type: ApplicationFiled: November 21, 2008Publication date: June 4, 2009Applicant: Boston Scientific Scimed, Inc.Inventors: Mehran Bashiri, Stella Chu, Esther Chang

Patent number: RE43311Abstract: This is an implant for placement in the human body and an assembly for so placing that implant. Most desirably, it is an implant for use in the vasculature of the human body and is used to occlude some space in that vasculature as a portion of a treatment regimen. The implant itself is preferably a component of a deployment device using an electrolytically severable joint. The implant component is at least partially covered with a highly resistive or insulative covering. The highly resistive or insulative layer or covering appears to enhance the susceptibility of the electrolytic joint to quick erosion and thus detachment of the implant. Although the implant itself is preferably a vaso-occlusive device, it may instead be a stent, a vena cava filter, or other implant which may be installed in this manner. The implant may be independently coated with insulative or resistive material or may be formed using a material with such as tantalum, which forms such an insulator or resistor in situ.Type: GrantFiled: February 14, 2007Date of Patent: April 10, 2012Assignees: Stryker Corporation, Stryker NV Operations LimitedInventors: Michael P. Wallace, Mehran Bashiri, Chad C. Roue
