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:
A medical device is disclosed. The medical device may include an elongate member having a lumen extending at least partially between a proximal end and a distal end of the elongate member. The medical device may also include a plurality of legs coupled to a distal portion of the elongate member, and a distal end piece connected to each of the plurality of legs and located distally to the distal end of the elongate member. The medical device may also include an actuating member coupled to the distal end piece and extending between the plurality of legs and through the lumen. The reciprocal movement of the actuating member may be configured to reversibly move the plurality of legs from a first position to a second position. The medical device may also include a stopping member coupled to the actuating member and configured to limit a movement of the actuating member.
Abstract:
An elevator of a medical device may comprise: a plurality of segments joined together by at least one hinge, and a control element coupled to at least one segment of the plurality of segments. A first segment of the plurality of segments may be a discrete structure. Proximal or distal movement of the control element may be configured to move the at least one segment of the plurality of segments relative to another of the plurality of segments.
Abstract:
A device may include a distal assembly including a first plurality of legs, a second plurality of legs, and a distal tip, and further include a first driver and a second driver, a proximal end of at least one leg of the first plurality of legs may be coupled to the first driver, and a proximal end of at least one leg of the second plurality of legs may be coupled to the second driver. The medical device may include a first longitudinally extending hollow member movably positioned along the first driver and a second longitudinally extending hollow member movably positioned along the second driver. Movement of the first longitudinally extending hollow member relative to the first driver may converge legs of the first plurality of legs, and movement of the second longitudinally extending hollow member relative to the second driver may converge legs of the second plurality of legs.
Abstract:
A resection device for resecting tissue from a body. The device includes an elongate member having a proximal end, a distal end, and a lumen extending from the proximal end to the distal end. The device further includes a cap assembly configured to be coupled to the distal end of the elongate member. The cap assembly may include a first cap defining a resection loop channel and a distal end having a first opening. The assembly may further include a second cap configured to receive a portion of the first cap. The second cap includes a distal end having a second opening. A distal portion of the first cap and a distal portion of the second cap may cooperate to define a resection loop track for receiving a resection loop.
Abstract:
A medical device may include a basket having a proximal end and a distal end. The medical device may further include a longitudinally extending member extending coupled to the proximal end of the basket. The medical device may further include a closure member extending along the longitudinally extending member and circumferentially about the distal end of the basket. Manipulation of the closure member may be configured to transition the distal end of the basket between a first closed position and a second open position.
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 medical device may include an expandable energy delivery array reciprocally movable between a first configuration and a second configuration. The expandable energy delivery array may include a first assembly having a first proximal end piece, a first distal end piece, and one or more first energy transfer elements extending between the first proximal and first distal end pieces, and a second assembly having a second proximal end piece, a second distal end piece, and one or more second energy transfer elements extending between the second proximal and second distal end pieces. The second proximal end piece may be proximal to the first proximal end piece and the second distal end piece may be distal to the first distal end piece.
Abstract:
An articulation joint for a medical device includes a proximal longitudinal section, a distal longitudinal section, and a locking wire. The proximal longitudinal section defines a lumen and includes proximal articulation links. Each proximal articulation link has a contact surface abutting a contact surface of an adjacent proximal articulation link when the articulation joint is in a straight configuration. The distal longitudinal section is distal to the proximal longitudinal section and includes distal articulation links configured to bend in the first direction. The locking wire extends through the lumen adjacent the contact surfaces of the proximal articulation links. A distal end of the locking wire is fixed to a distal articulation link, and tensioning of the locking wire prevents bending of the proximal longitudinal section in the first direction and allows bending of the distal longitudinal section in the first direction.
Abstract:
A medical device includes a shaft. The shaft includes an integral tube defining a plurality of lumens. The integral tube is comprised of at least one of PTFE and ePTFE. A density of the at least one of PTFE and ePTFE varies along a length of the integral tube.
