Disclosed herein is a percutaneous catheter apparatus, comprising two nested needles; and an inner plunger; which is guided as a catheter to the tissue surrounding a hard implant to actuate and deploy a pair of sharp-tip needle-forceps that perform two concentric cuts, circularly spaced 90-degree apart from each other, to complete a 360 degree bore around the implant before squeezing to arrest and extract the implant, together with its surrounding tissue.

An apparatus for guiding an elongated flexible instrument, includes a first plurality of linkages forming a first side of a channel of a variable-length support assembly, a second plurality of linkages forming a second side of the channel, opposite the first side, a third plurality of linkages disposed between the first and second plurality of linkages and forming a third side of the channel, and a fourth plurality of linkages disposed between the first and second plurality of linkages and forming a fourth side of the channel, opposite the third side. Each of the first, second, third, and fourth pluralities of linkages are separable from each other to transition the variable-length support assembly from an elongated configuration to a compact configuration.

An endosurgical device is provided. The endosurgical device comprises a flexible tube having at least two lengthwise extending channels, an end effector comprising two opposite jaws having opposite cutting edges, an effector sleeve that surrounds the tube at least at the distal tube end, and means for reciprocating the end effector axially in relation to the effector sleeve to close the jaws when the effector sleeve is moved forward and backwards to close and open the jaws, respectively. The exterior face of the opposite jaws is electrically insulated, and an electrical cord for providing current to the end effector extends inside one of the lengthwise extending channels of the tube. The endosurgical device may allow the surgeon to take several tissue specimens from an organ and to perform several functionalities when the device is inside the organ.

An improved biopsy tray includes a container having bottom surface and continuous perimeter wall extending upward therefrom to form a cleaning zone which is sufficient to hold an adequate amount of fluid for cleaning a biopsy forceps, and at least one specimen bottle receiving receptacle adjacent the perimeter wall to receive and retain a specimen bottle. A method of obtaining a biopsy specimen includes employing the tray of the invention.

A medical device comprising a handle extending between a first end and a second end, a first actuator coupled to the first end of the handle, a first shaft coupled to the second end of the handle, and a second shaft extending from the first shaft, the second shaft including a first articulation section and a second articulation section, wherein an articulation of the first actuator relative to the handle is configured to articulate the first articulation section, an articulation of the handle relative to the first shaft is configured to articulate the second articulation section, and the first articulation section and the second articulation section are restricted to articulating only in a first plane.

An endoscope treatment instrument having a sheath, a rotation axis extending in a width direction orthogonal to a longitudinal direction of the sheath, a plate formed with a first opening through which the rotation axis passes and a second opening having a width different from the width of the first opening, a forceps piece rotatably supported about the first opening and the rotation axis passing through the second opening, and a wire connected to a proximal end portion of the plate.

TNE provides the opportunity to make the care of children with EoE and other gastrointestinal or aerodigestive conditions safer, more efficient, and less costly while simultaneously advancing our understanding of the pathophysiology and natural course of this condition. A pediatric endoscope was developed to facilitate TNE in children with EoE. The pediatric endoscope (combined gastroscope, bronchoscope, laryngoscope) includes a 3-4 mm flexible, fiber optic endoscope that allows HD TV viewing with the head of a pediatric bronchoscope that allows four way tip deflection, a scope stiffening apparatus to minimize the endoscopes flexibility when needed, a foot and hand activation to allow air/water insufflation and image/video capture, a light source, 2 mm biopsy channel.
