Abstract: An instrument and method are provided for sealing and joining or hemostatically dividing tissue, which is particularly suitable for laparoscopic and endoscopic surgery. The instrument makes use of the controlled application of a combination of heat and pressure to seal adjacent tissues, to join adjacent tissues, or to anastomose tissues, whereby tissue is heated for an optimal time and at an optimal temperature under optimal pressure to maximize tissue seal strength while minimizing collateral tissue damage. The instrument of the present invention is lightweight and therefore portable, and is particularly useful in field conditions where a source of external power may not be readily available.

Abstract: Balloon loaded dissection devices and methods for using such devices are disclosed. The devices include an elongate balloon and may be provided with a central lumen. The device may have a guide tube to provide columnar support. In a further aspect, the guide tube may have a spoon-shaped shroud attached to a distal end. The guide tube receives the guide rod, scope or other surgical instrument and may have a stop member. By using the guide rod or scope as a pushing member, the device may be advanced alongside the vessel it is desired to dissect free from attached tissue. A balloon cover may be provided to surround the balloon and facilitate compression of the balloon after it is deflated.

Abstract: Methods and apparatus for crossing totally to substantially occluded blood vessels by passing a redirectable wire such as a guidewire from a relatively proximal point past the occlusion within a subintimal space formed between the intimal layer and the adventitial layer of a blood vessel wall. The wire may be advanced to a point distal to the occlusion, and thereafter deflected back into the blood vessel lumen, typically using a deflecting catheter which is advanced over the guidewire after it has been positioned within the subintimal space. The deflecting catheter may include a flapper valve assembly or preformed actuator wire for redirecting the guidewire. After the guidewire is returned to the blood vessel lumen, the deflecting catheter may be withdrawn, and the guidewire may be available for introduction of other interventional and diagnostic catheters for performing procedures such as stenting.
