Abstract: A patterned tube for use with a scope or similar medical device can include at least one flexible section. The at least one flexible section can include a plurality of first cuts having a first thickness, a plurality of second cuts having a second thickness. Particular ones of the plurality of second cuts can be located substantially opposite particular ones of the plurality of first cuts. The at least one flexible section can further include a plurality of bending moment transfer portions. Particular ones of the bending moment transfer portions can be located between particular ones of the first cuts and particular ones of the second cuts.

Abstract: Devices for guiding an instrument into a body of a patient, at a targeted point of entry and along an insertion path at a targeted insertion angle, are described herein, such as a guide for an access needle in a PCNL procedure for accessing the kidney to remove kidney stones. The devices include base component aligned with a point of entry, and a guide assembly which cooperates with the base component to allow an instrument to be aligned and fixed at various circumferential and vertical angles. The devices and methods allow a medical professional to accurately and stably guide an instrument at a targeted point and angle and to a desired depth, while minimizing the exposure to radiation used to image the insertion path.

Abstract: Devices for guiding an instrument into a body of a patient, at a targeted point of entry and along an insertion path at a targeted insertion angle, are described herein, such as a guide for an access needle in a PCNL procedure for accessing the kidney to remove kidney stones, the devices comprising a base component, a guide assembly, and optionally an insertion mechanism. The base component is aligned in use with the point of entry and the guide assembly cooperates with the base component to allow for the instrument to be aligned and fixed at any circumferential angle around an axis perpendicular to the point of entry and at any vertical angle ranging from 0 to 45 degrees away from the axis in a direction toward the body. The optional mechanism allows for mechanical insertion once the instrument is aligned and fixed.

Abstract: A medical device may include a sheath, an elongate member at least partially surrounded by the sheath, an end effector at a distal end of the elongate member and movable between an open position and a closed position, and a handle. The handle may include an actuator member coupled to the sheath, an adjustment member, and a biasing member extending between the actuator member and the adjustment member.

Abstract: A percutaneous nephrolithotomy (PCNL) needle may include a cannula including a shaft and a cannula hub coupled to a proximal end of the cannula shaft. A depth guide may be disposed on an outer surface of the cannula shaft. A stylet may be disposable within the cannula lumen and may include a tapered point at a distal end of the stylet and a stylet hub coupled to a proximal end of the stylet that is configured to be releasably securable to the cannula hub. An adjustable depth stop may be releasably securable to the cannula shaft at a desired position relative to the depth guide, the adjustable depth guide capable of being manipulated between an adjustment configuration in which the adjustable depth guide is moveable relative to the cannula shaft and a secured configuration in which the adjustable depth guide is secured relative to the cannula shaft.

Abstract: In one embodiment, a medical device includes a tissue anchor has a first portion and a second portion. The tissue anchor is configured to be placed within bodily tissue of a patient. The first portion of the tissue anchor includes an extension member configured to engage the bodily tissue to help retain the tissue anchor within the bodily tissue. The first portion has an inner surface and defines a cavity. The second portion of the tissue anchor has a helical ridge. The helical ridge is configured to engage the inner surface of the first portion of the tissue anchor to movably couple the second portion of the tissue anchor to the first portion of the tissue anchor.

Abstract: In some implementations, a medical device includes a clamp component and a strap. The clamp component has a portion configured to be placed around a urethra of a patient. The clamp component includes a first end portion configured to be lockably coupled to a second end portion of the clamp component. The strap has a portion extending between a first portion of the portion of the clamp component and a second portion of the portion of the clamp component.

Abstract: A medical device includes a sheath extending from a proximal end to a distal end and having a lumen extending therethrough and an end-effector disposed at the distal end of the sheath including a first resection loop configured to resect tissue and a secondary tool including one of a second resection loop and a tissue-vaporizing structure mounted distally to the first resection loop.
