Abstract: Marker systems and methods for implanting a marker are provided. In one embodiment, a marker system can include an elongate cannulated tube, a marker capsule, and a driver member. The cannulated tube can have a piercing feature arranged at a distal end thereof that is configured to create a working portal through tissue such that fluid can be delivered into the tissue to form a bleb. The marker capsule can be removably disposed within the lumen of the cannulated tube. The marker capsule can include a transmission antenna, and an arranging feature disposed on an external surface configured to facilitate rotation of the marker capsule within the bleb. The driver member can be arranged within the lumen of the cannulated tube proximal to the marker capsule. The drive member can be configured to advance distally to displace the marker capsule through the working portal and into the bleb.

Abstract: A system and method for marking sites of biopsied tissues using markers, such as radiopaque microspheres, ink-like stain, and radio-frequency identification chips, delivered to the site of the biopsy by a construct advanced through a port in a colonoscope and locatable by x-ray equipment, a camera attached to a colonoscope, or a radio-frequency identification chip reader.

Abstract: An implantable prosthesis is provided for repairing or augmenting anatomical weaknesses or defects, and is particularly suitable for the repair of soft tissue and muscle wall openings. The prosthesis includes a repair fabric with a generally triangular-shaped body and two tails extending outward from the base of the triangular body. The tails may be rounded to provide the repair fabric with a generally heart-shaped configuration. An opening is provided along the base of the body and between the two tails for receiving a tube-like structure, such as the esophagus. The prosthesis may include a layer of fabric that is constructed and arranged to allow tissue ingrowth and is susceptible to erosion into and the formation of adhesions with tissue and organs. One or more regions of the prosthesis may be configured to inhibit erosion into and/or the formation of adhesions with tissue and organs. The prosthesis may include an edge barrier that is attached to the tails and overlies a portion of the opening.
