Systems and methods for infusion of fluids using stored potential energy and a variable flow resistor. In one aspect of the present disclosure, there is provided an infusion device that includes a plunger situated within a vessel so as to define a chamber within which a volume of fluid can be accommodated between a downstream surface of the plunger and the vessel. The infusion device further includes an outflow path through which the fluid in the chamber can be dispensed upon displacement of the plunger by a force acting thereon. A variable flow resistor is situated within the outflow path and is configured to allow a substantially constant fluid flow rate from the vessel to be maintained as the force acting on the plunger decreases.

A system for removing undesirable material from vessels and from chambers within the heart is provided. The system includes a suction cannula for removing the undesirable material from a site of interest within a patient. A filter device may be provided for capturing the undesirable material and removing it from the fluid flow. The system also includes pump for generating the necessary suction force through the suction cannula to dislodge the undesirable material from the site of interest and for generating a sufficient driving force to direct the fluid flow downstream within the system. The system further includes a reinfusion cannula for introducing fluid removed from the site of interest back into a patient. A method for removing undesirable material from vessels and from heart chambers is also provided.

A system for tubular ligation is disclosed. The system may include an anchor designed to advance into a channel and engage the walls of the channel. The anchor may have mechanisms that allow it to securely attach to walls of the channel and pull the channel. The system may also include a body for placement adjacent to the channel to align the anchor with the channel. The anchor and body may be arranged so that subsequent retreat of the anchor toward the body pulls and inverts a portion of the channel. The system may also include an occlusion mechanism for placement about the inverted portion of the channel to seal the channel. The occlusion mechanism may be configured to bias between an open state for placement on the body, and a compressed state for sealing the channel. A method for tubular ligation is also disclosed.

A system for tissue or organ removal is provided. The system has an outer bag having an exit end, and an inner bag situated within the outer bag and having an opening capable of receiving an organ or tissue. The inner bag may be sealed to the exit end of the outer bag about its opening. A fluid-tight space may be situated between the outer bag and the inner bag. The space may be designed to accommodate positive pressure which can act on the inner bag to cause the inner bag to evert and expel the organ or tissue. The system may also include an organ receiving component for receiving the organ as it is expelled. Methods for tissue or organ removal is also provided.

The present invention provides, in one embodiment, a vascular filter device for capturing dislodged blood clots within a vessel. The vascular filter device includes an expandable framework for securing the device within a vessel. The device also includes a pathway extending through the framework. The device further includes at least one filter in alignment with the pathway for capturing dislodged clots or emboli. In an embodiment, the filter can be given form by a material that can be easily eliminated in situ to permit reestablishment of the pathway.

The present invention provides bariatric therapy systems. One system includes a gastrointestinal implant device and a delivery mechanism therefor. The device can include a sleeve for placement into a small intestine and to minimize absorption of nutrients by its walls. An anchoring mechanism coupled to a proximal end of the sleeve and designed to be secured within the stomach can be provided. A passageway extending through the anchoring mechanism and the sleeve can also be provided, along which food can be directed from the stomach to the small intestine. The delivery mechanism can include a housing for accommodating the device, and a deploying balloon situated within the housing and which can be actuated to direct the sleeve of the device from within the housing to the site of implantation. Methods for providing bariatric therapy are also provided by the present invention.
