Abstract:
A system for measuring a pressure in a vein includes a needle sized and shaped to be inserted through a working channel of an endoscope. The needle is extending longitudinally and including a channel extending longitudinally therethrough. The system also includes a pressure sensing device including a longitudinally extending body sized and shaped to be slidably inserted through the channel of the needle and a sensor mounted on a distal portion of the body and connected to a proximal portion of the pressure sensing device via a connection cable. The sensor is configured to detect information corresponding to a pressure of a flow of blood through a vein.
Abstract:
A medical device may include a needle, including a plurality of links and a distal tip, reciprocally movable between a first configuration and a second configuration, and a conduit including a lumen extending through the needle, the conduit being coupled to the distal tip, wherein longitudinal movement of the conduit is configured to transition the needle between the first configuration and the second configuration.
Abstract:
A system for controlling the flow of fluid through a medical device may include a medical device having a lumen that extends to a distal end of the medical device; a fluid source configured to supply fluid having a positive pressure to the lumen of the medical device; and a flow controller configured to apply a negative pressure to the fluid within the lumen, wherein the flow controller is triggered to apply the negative pressure upon a lowering of the positive pressure from the fluid source.
Abstract:
A method for isolating a portion of a lung may include inserting a treatment device into an airway of a patient, and applying energy from the treatment device to a treatment site in the airway to at least partially occlude the airway to inhibit air from entering the airway distal to the treatment site.
Abstract:
A combined system for diagnostic and therapeutic procedures includes a needle extending longitudinally from a proximal end to a distal end and including a lumen extending therethrough, the distal end including a sharp grind for cutting a tissue sample to be collected in the lumen of the needle and a protective sheath sized and shaped to be inserted through the lumen of the needle such that a distal end of the protective sheath extends distally past the distal end of the needle, the protective sheath extending longitudinally from a proximal end to the distal end and including a lumen extending therethrough.
Abstract:
Systems and methods for treating tissue may include one or more delivery devices, a grasping element, a first ring for anchoring to a wall of a gastrointestinal tract, and a second ring operably couplable to a radially inward surface of the first ring. Other embodiments include methods of treating tissues, including tubular tracts of tissue, comprising coupling a first ring to first tissue of a wall of a tissue tract, relocating a target tissue proximally to a position proximal to the first ring, coupling a second ring to the first ring, and cutting tissue proximal to the interface of the first and second rings.
Abstract:
This disclosure provides design, material, manufacturing method, and use alternatives for medical devices. An example medical device may include a medical device for delivery of a surgical closure member. The medical device includes an elongate tubular member having a proximal end, a distal end and a lumen extending therein. The elongate tubular member is adapted to be delivered through the working channel of an endoscope and the lumen is adapted to receive a surgical closure member. The medical device also includes a tissue support extending from the distal end of the elongate tubular member. The tissue support includes a support surface and the support surface is adapted to support tissue as a surgical closure member engages the tissue thereon.
Abstract:
Methods and devices for at least partially occluding an airway of a lung is disclosed. The method includes deploying a catheter into the airway such that a balloon at a distal end of the catheter is positioned proximate a tissue wall that defines the airway, and inflating the balloon to cause pressure to be applied on a portion of the tissue wall. The method may also include deflating the balloon to cause the portion of the tissue wall to be drawn radially inward to at least partially occlude the airway.

Abstract:
Embodiments of the disclosure include methods and systems for attaching an articulation section. In an embodiment, a medical instrument includes a first tubular member including a first end. The medical instrument also includes a second tubular member including a first end. The second tubular member includes a plurality of layers including an inner layer and a first layer including a fluorinated material. The inner layer includes a first section disposed under the first layer and a second section extending out from under the first layer. A portion of the first tubular member overlaps and is bonded to at least a portion of the second section of the inner layer of the second tubular member.
