Publication number: 20080221654Abstract: Disclosed herein are various systems and methods for delivering implantable devices, such as, for example detachable embolic coils. The systems can include an embolic coil mated to a pusher wire via a detachable link comprising first and second engaging members and an expandable member or a sleeve. The expandable member or sleeve can reduce relative movement between the engaging members to inhibit premature detachment and/or jamming of the detachable link as the embolic coil is delivered through a catheter.Type: ApplicationFiled: February 29, 2008Publication date: September 11, 2008Inventors: Marcia Buiser, Christopher Nardone, Christopher J.

Publication number: 20040199179Abstract: A probe assembly and method for ablating tissue is provided. The probe assembly comprises an elongated shaft having a rigid section and a flexible section distally extending from the rigid section. The probe assembly further comprises a tissue penetrating element associated with the flexible section. For example, it can be mounted to the flexible section or can be located on a separate element, such as a trocar that can be disposed within the elongated shaft. The probe assembly further comprises one or more ablative elements, such as electrodes, that is associated with the flexible section. Like the tissue penetrating element, the ablative element(s) can be mounted to the flexible section or can be located on a separate element. Thus, the flexible section of the shaft can be flexed to deflect the tissue penetrating element, so that it can be steered through tissue. In this manner, sensitive anatomical structures can be avoided, e.g.Type: ApplicationFiled: April 2, 2003Publication date: October 7, 2004Inventor: Christopher J. Elliott
