摘要： A medical device and a method of using such medical device for removing targeted tissue from a body lumen in a patient is presented. The method generally comprises placing the distal end of the device through a natural orifice in the patient to a location that is proximate to the targeted tissue; deploying a T-anchor fastened to a suture strand through the targeted tissue; deploying a loop anchor into the tissue of the body lumen spaced away from the targeted tissue, whereas the suture strand is slidably received by the loop anchor; applying tension to the suture strand; cutting the tissue at a predetermined depth around the periphery of the targeted tissue; and removing the targeted tissue along with the T-anchor from the body lumen. The tension applied to the targeted tissue maintains the targeted tissue in a raised position and/or allows the physician to manipulate the targeted tissue relative to the tissue that is proximate to it.

摘要： Medical devices and related methods are provided for closing a perforation in a bodily wall. The medical device generally includes a set of tissue anchors and an elongate tensioning member. Each anchor includes a crossbar having opposing ends and defining a longitudinal axis. A strand is connected to the crossbar at a location between the opposing ends and projects away from the longitudinal axis. The strand includes a distal end connected to the crossbar and a proximal end having a first connector. The elongate tensioning member is structured to selectively engage and disengage the first connector. The strands of the anchor are capable of being tensioned and fixed together for closing the perforation. The tensioning member is removed after the strands are fixed together.

摘要： The present embodiments provide apparatus and methods suitable for containing and delivering a therapeutic agent to a target site. The apparatus generally comprises at least one container for holding a therapeutic agent, and a pressure source for facilitating delivery of the therapeutic agent. In one embodiment, the pressure source may be placed in selective fluid communication with a proximal region of the container and fluid from the pressure source may flow through at least a portion of the container to urge the therapeutic agent through the container towards the target site. In an alternative embodiment, the pressure source may be selectively in fluid communication with either a first hollow tube and the container so that therapeutic agent is urged into a catheter, or with a second hollow tube and a catheter so that a fluid from the pressure source bypasses the container and enters the catheter.

摘要： An echogenic electrosurgical device and a method for electrosurgically treating a target site are provided. The device includes an elongate body having a proximal portion and a distal portion. The distal portion of the elongate body includes an echogenic region, a coated portion providing an electroinsulative layer and an uncoated electroconductive electrosurgical region. The coating allows reflection of ultrasonic waves from the coated echogenic region sufficient for ultrasonic imaging of the echogenic region at a resolution providing for effective navigation in a body. The coated region has a first surface area and the electrosurgical region has a second surface area. The first surface area is greater than the second surface area.

摘要： The present embodiments provide systems and methods suitable for delivering a therapeutic agent to a target site. The systems generally comprise a container for holding a therapeutic agent, and a pressure source configured to be placed in selective fluid communication with at least a portion of a reservoir of the container. In one embodiment, fluid from the pressure source is directed through a first region of the container in a direction towards a second region of the container. The fluid then is at least partially redirected to urge the therapeutic agent in a direction from the second region of the container towards the first region of the container and subsequently towards the target site. In alternative embodiments, the fluid from the pressure source may be directed through the second region of the container in a direction towards the first region of the container.

摘要： A stent delivery system and a method for delivering a stent are provided. The stent delivery system includes an outer sheath having a proximal portion, a distal portion and a first lumen extending at least partially through the sheath. The system further includes an inner shaft slidably received within the first lumen and extending at least partially through the sheath. A tubular non-expandable stent is slidably positionable within the first lumen, disposed distal to the inner shaft and operably contacts a pushing surface on the inner shaft. The inner shaft and the stent are slidable relative to the outer sheath, the outer sheath providing sufficient rigidity to the stent for delivery of the stent to a delivery site.
