A tissue removal device includes an outer tubular member coupled to a housing and a having a tissue resection window, an inner tubular member slidably disposed within the outer tubular member, a tissue trap having a sealed interior in fluid communication with a vacuum chamber, an open proximal end of the inner tubular member being disposed within the tissue trap interior, and an actuator moveably coupled to the housing and operatively connected to a movable piston in the vacuum chamber, such that movement of the actuator relative to the housing generates a vacuum in the tissue trap.

The present invention relates to a needle-type endoscope, including a camera tube having an image capturing means accommodated therein; a needle covering the camera tube from the outside and having a sharp tip formed in a front end thereof to make an incision in a human body; and a handle, wherein a length of the camera tube is formed to be longer than a length of the needle. Accordingly, it is possible to provide a needle-like endoscope configured such that a camera tube for acquiring an image is disposed inside a needle for making an incision in the human body in such a manner as to be moved forward and backward in a sliding manner inside the needle, thereby excluding constituents such as a cannula or a sheath for providing an insertion path for an endoscope, and an incision instrument.

An apparatus with a deployable blade for probing and cutting can include an elongate member having a probe and a blade associated with a first end thereof. The probe can include a target interaction surface that is selectively movable between a retracted state and a target acquisition state. The blade includes a cutting edge and is selectively movable between a retracted position and an extended position. The handheld apparatus may additionally include a manually operated control that is operably connected to the probe and/or the blade to cause the retraction/extension of the probe and/or blade.

The present disclosure is directed to a medical device. Systems and methods are provided for accessing and visualizing the pancreatico-biliary system. The medical device may include a guide catheter with a first lumen and a second lumen. A first elevator may be disposed in the first lumen, wherein the first elevator is movable relative to the first lumen for elevating a first tool insertable into the first lumen. A second elevator may be disposed in the second lumen, wherein the second elevator is movable relative to the second lumen for elevating a second tool insertable into the second lumen.

A surgical device is disclosed including a surgical instrument and an outer sheath surrounding the surgical instrument. The surgical instruments includes an end effector including a first jaw member and a second jaw member. At least one of the first jaw member or the second jaw member is pivotable toward the other to grasp tissue. The outer sheath is slidable relative to the surgical instrument along a longitudinal axis between a first position, wherein the first jaw member and the second jaw member are positioned within the outer sheath proximal to a distal portion of the outer sheath, and a second positon, wherein the first iaw member and the second iaw member are positioned outside the outer sheath distal to the distal portion of the outer sheath. The distal portion of the outer sheath is configured to clamp tissue.

Devices and methods for trimming a stent to a desired length with an outer tube and an inner tube having a distal end and a diameter configured to receive a portion of the stent in excess of the desired length. The inner tube may move within the outer tube and the distal end may include an end effector configured to trim the portion from the stent while the device and stent are within a patient.

A device for removing an implanted object from a body vessel includes an actuator having an elongated sheath extending therefrom, the elongated sheath including a proximal portion and a distal portion. A tubular outer member has a proximal end attached to the distal portion of the elongated sheath, with a ramped surface at a distal end of the tubular outer member which constricts a diameter of a bore formed in the tubular outer member. A tubular inner member is located within the tubular outer member, the tubular inner member including a proximal end operably connected to the actuator and a distal end opposite the proximal end, the distal end of the tubular inner member including a plurality of resiliently flexible blades positioned to interact with the ramped surface of the tubular outer member such that the ramped surface is operable to deflect the resiliently flexible blades radially inwardly as the tubular inner member is advanced distally within the tubular outer member.

A double-joint sickle knife for an endoscopy therapy includes a knife head, a knife base, a knife body, an outer sheath, a guide wire, a handle and a sliding rod. The knife head is connected with one end of the knife base by a transverse joint, and the other end of the knife base is connected with a head end of the knife body by a longitudinal joint. The outer sheath is sleeved on the outside of the knife body and capable of sliding along the knife body. The tail end of the knife body is connected with one end of the handle, and a sliding rod for adjusting the transverse joint is arranged on the handle. The guide wire is electric conductive. One end of the guide wire is connected with the knife head, and passes through the knife base, the knife body, the handle and the sliding rod successively. The other end of the guide wire is connected with the power port.

An extraction device can include a delivery shaft having a lumen and a distal end, a first wire forming a first arc and being positionable distal to the distal end of the delivery shaft while ends of the first arc are at a distalmost end of the delivery shaft, and a second wire forming a second arc and being positionable distal to the distal end of the delivery shaft while ends of the second arc are at the distalmost end of the delivery shaft. A distalmost extent of the first wire is distal to a distalmost extent of the second wire. The first wire and the second wire are separately retractable relative to the delivery shaft.

Methods and devices for separating an implanted object, such as a pacemaker lead, from tissue surrounding such object in a patient's vasculature system. Specifically, the tissue separating device includes a handle, an elongate sheath and a circular cutting blade that may extend from the distal end of the sheath upon actuating the handle. The elongate sheath, particularly its distal end, includes a non-uniform wall thickness having one or more thicker portions in the outer sheath, particularly the outer cam member, and/or one or more thicker portions in an inner member disposed radially inward of the blade.
