In one aspect, the dual bevel needle can include a hollow tube having a proximal end, a distal end, a first lateral side, and a second lateral side opposite the first lateral side; a first needle point at the distal end of the hollow tube; a second point at the distal end of the hollow tube; a first bevel on each of the first lateral side and the second lateral side, the first bevel comprising a first bevel angle relative to a longitudinal axis of the tube; and a second bevel on each of the first lateral side and the second lateral side, the second bevel having a second bevel angle relative to the longitudinal axis of the tube, wherein the first and second bevels each form a portion of an ellipse, the ellipse having an inner cutting edge and terminating in the first and second needle points at the distal end of the tube, the second bevel angle being shallower than the first bevel angle, the second bevel being located adjacent the proximal end of the first bevel, and the inner cutting edge converging to a narrow heel.

Method and system for harvesting biological tissue

A device for ablating target tissue of a patient with an ablative fluid is provided. An elongate shaft includes a proximal portion and a distal portion, and at least one fluid delivery element is attached to the distal portion. The device can be configured to ablate the duodenal mucosa of a patient while avoiding damage to the duodenal adventitial tissue. Systems and methods of treating target tissue are also provided.

Ablation systems, devices and methods for the treatment of tissue

A system for treatment target tissue comprises an ablation device and an energy delivery unit. The ablation device comprises an elongate tube with an expandable treatment element. The system delivers a thermal dose of energy to treat the target tissue. Methods of treating target tissue are also provided.

Heat ablation systems, devices and methods for the treatment of tissue

A device for expanding tissue comprises at least one fluid delivery tube and at least one fluid delivery element in fluid communication with the at least one fluid delivery tube. The at least one fluid delivery tube comprises a proximal end, a distal end, and a lumen therebetween. The device is constructed and arranged to perform a near full circumferential expansion of luminal wall tissue. Systems and methods are also provided, including a system for expanding tissue layers and treating tissue proximate to the expanded tissue layers.

Tissue expansion devices, systems and methods

A system for treating a patient comprises an elongate shaft, an expandable reservoir and a fluid delivery assembly. The elongate shaft comprises a distal portion and is constructed and arranged to be introduced into a gastrointestinal lumen. The expandable reservoir is positioned on the elongate shaft distal portion and is constructed and arranged to receive a first fixed amount of ablative fluid and to deliver a first thermal dose of energy to a first portion of target tissue. The fluid delivery assembly is in fluid communication with the expandable reservoir and is constructed and arranged to deliver the first fixed amount of ablative fluid to the expandable reservoir. Devices and methods for treating tissue of a patient are also provided.

Systems, methods and devices for treatment of target tissue

Systems, methods and devices for the treatment of tissue are disclosed. A system includes an elongate tube with a distal portion. A treatment element is positioned on the elongate tube distal portion, the treatment element constructed and arranged to treat target tissue. In one embodiment, gastrointestinal tissue is modified for the treatment of diabetes.

Devices and methods for the treatment of tissue

Minimally invasive systems and methods are described for measuring pulmonary circulation information from the pulmonary arteries. A transbronchial Doppler ultrasound catheter is advanced through the airways and in the vicinity of the pulmonary artery. Doppler ultrasound energy is sent through the airway wall and across the pulmonary artery to obtain velocity information of blood flowing through the artery. The velocity information is used to compute pulmonary circulation information including but not limited to flowrate.

Method and system for measuring pulmonary artery circulation information

Physically flexible radiation-emitting probes and associated illumination methods and systems for delivering radiation or light to the interior of a lumen or cavity. Light-emitting devices are immersed in a flowing liquid coolant within a probe to provide high light output power, and convoluted electrical power buss structures provide physical flexibility of a probe about a longitudinal axis. The probes can be configured for delivering light to the interior of any lumen including for performing therapeutic medical procedures at locations in body lumens including the interior of the human gastrointestinal tract.

Phototherapy device and system

The present invention relates to a devices and methods for killing and/or debilitating pathogenic microorganisms in or on a patient's body, such as light-sensitive bacteria includingand/or. A chemiluminescent light source provides electromagnetic radiation having predetermined wavelengths in the visible spectrum. The light wavelengths are selected for absorption by naturally-occurring photosensitive chemicals produced by the patient's body.
