A method of using a suction device to remove an object from a subject's body includes extending a suction device into the body through a lumen of a medical device and expanding the suction head from a contracted configuration to an expanded configuration within the body. The suction head may be provided at a distal end of an elongate conduit. The method may also include applying suction to move the object into the expanded suction head, and removing the suction device with the object from the body.

Kidney stone suction device

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. Devices and methods disclosed herein 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 in the surgical field that is used to image the insertion path.

Devices and methods for guiding a surgical instrument

This disclosure concerns systems and methods for removal of material from the body of a patient, and particularly for percutaneous nephrolithotomy. Systems according to the various embodiments of the disclosure include one or more of nested first and second components, for instance a scope nested within a suction or irrigation catheter, guidewires with self-expanding distal tips, and wash-out elements to facilitate rapid removal of stones through an access sheath.

Retrieval system

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.

Retrieval basket and related methods

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.

Adjustable implants and methods of implanting the same

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.

Implantable medical device and methods of delivering an implantable medical device

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.

Resection loop for tissue resection and related method of use

An apparatus may include a handle having a first portion and a second portion. The second portion may extend at an angle from the first portion. The handle may also include a passage configured to receive a medical device therethrough and defined by the first portion. Further, the handle may include an actuator operably coupled to the first portion. The apparatus may also include an endoscopic insertion device coupled to and extending distally of the first portion of the handle. Further, manipulation of the actuator may be configured to deflect a distal portion of the insertion device.

Medical retrieval systems and related methods

Medical devices, systems, and related methods of use are disclosed. The systems may comprise a sheath for insertion into a body lumen and an extraction tool for passage through the sheath, wherein the extraction tool may include a handle, an end effector, and an optical device. Methods disclosed herein include introducing an extraction tool into a urethra for retrieving and removing tissue from the body, e.g., with an end effector, without morcellating the excised tissue.

Systems, devices, and methods for tissue extraction

A marking device may include a body. The body may be configured to transition between a closed configuration and an open configuration. The body may further include two arms. A distal end of each arm may be coupled to a distal end of the body. The marking device may further include a suture coupled to the body. Application of a force on a proximal end of each arm may be configured to cause the body to transition between the closed configuration and the open configuration.

Tissue extraction devices and related methods

A device may include a handle, and a sheath coupled to the handle. The sheath may include a lumen. The device may also include an instrument assembly coupled to the handle, and extending through the lumen of the sheath. The instrument assembly may include a basket configured to move relative to the sheath, and between contracted and expanded states. The instrument assembly may also include a forceps configured to reciprocate along a central longitudinal axis of the basket and through an interior of the basket, and move between contracted and expanded states.

Multifunction retrieval devices and related methods

A stent delivery device having a locking mechanism. The device includes a handle assembly, an elongate inner member, and an elongate outer tubular member surrounding the elongate inner member. The handle assembly includes a handle attached to one of the inner member and the outer tubular member, and an actuator attached to the other of the inner member and the outer tubular member. Actuation of the actuator relative to the handle between a first position and a second position causes axial movement of the outer tubular member relative to the inner member. The locking mechanism has a locked position in which the actuator is prevented from moving from the first position to the second position and an unlocked position in which the actuator is permitted to move from the first position to the second position.
