Patent number: 8892185Abstract: Apparatus, systems, and methods are provided for localizing lesions within a patient's body, e.g., within a breast. The system may include one or more markers implantable within or around the target tissue region, and a probe for transmitting and receiving electromagnetic signals to detect the one or more markers. During use, the marker(s) are into a target tissue region, and the probe is placed against the patient's skin to detect and localize the marker(s). A tissue specimen, including the lesion and the marker(s), is then removed from the target tissue region based at least in part on the localization information from the probe.Type: GrantFiled: June 25, 2010Date of Patent: November 18, 2014Assignee: Cianna Medical, Inc.Inventors: Eduardo Chi Sing, Mark A.

Publication number: 20140309522Abstract: Apparatus, systems, and methods are provided for localizing lesions within a patient's body, e.g., within a breast. The system includes a microwave antenna probe for transmitting and receiving electromagnetic signals to detect one or more markers that are implanted within or around the target tissue region. During use, the marker(s) are implanted into a target tissue region, and the microwave antenna probe is placed against the patient's skin to transmit a signal to the marker(s) and to receive the reflected signal from the marker(s) in order to determine the location of the marker(s). A tissue specimen, including the lesion and the marker(s), is then removed from the target tissue region based at least in part on the location information from the microwave antenna probe.Type: ApplicationFiled: January 27, 2014Publication date: October 16, 2014Inventors: Larry W.

Patent number: 8050741Abstract: A biopsy cannula and a delivery catheter are configured to deliver one or more absorbable sponge pledgets to a biopsy site after removal of one or more tissue samples from the site. The delivery catheter allows a large amount of hydrated sponge material to be delivery to the biopsy site to facilitate hemostasis. One example of the delivery catheter includes a closed distal end, a side port, a tapered section, and an enlarged proximal portion for receiving the pledget. The side port of the delivery catheter is arranged to delivery the pledget through the side port of the biopsy cannula. In order to fill a relatively large biopsy site where multiple tissue samples have been taken in a radial pattern, the biopsy cannula is rotated and additional pledgets are delivered to the biopsy site at different radial locations. The absorbable sponge pledget may also be used as a marker for location of the biopsy site at a later time.Type: GrantFiled: December 21, 2004Date of Patent: November 1, 2011Assignee: Boston Scientific Scimed, Inc.Inventors: Mark Ashby, Vaughn P.
