The invention provides systems, devices, and methods for the delivery, deployment, and positioning of magnetic compression devices at a desired site so as to improve the accuracy of anastomoses creation between tissues, organs, or the like.

Systems, devices, and methods for forming anastomoses

A magnetic compression anastomosis device comprises a plurality of interconnected vertebrae including a first vertebra and a second vertebra, wherein each of the first vertebra and the second vertebra is a multipiece vertebra comprising a magnet at least partially encapsulated by a vertebra skin, and wherein the first vertebra and the second vertebra are interconnected by a cylindrical roller and at least one flex element, the roller and the at least one flex element at least partially encapsulated by the first vertebra skin and the second vertebra skin, the roller configured to allow the first and second vertebra to pivot through a predetermined range of rotation in a device plane between at least a delivery configuration and an assembled configuration while constraining movement in other degrees of freedom, the at least one flex element biasing the first and second vertebra toward the assembled configuration.

Magnetic compression anastomosis device with multipiece vertebra

Compression anastomosis devices having a plurality of distinct pressure profile zones on the surface of the device. The anastomosis devices may be comprised of a plurality of magnetic connecting members arranged in an annular geometry, e.g., a polygon or circle. The anastomosis device may also be a continuous, non-segmented magnet, or other compression anastomosis device. The compression anastomosis device is deployed into a body lumen, e.g., endoscopically and/or laparoscopically, at a target site. A second compression anastomosis device is placed at an adjacent target site in an adjacent lumen. The compression anastomosis devices are brought together and mate, e.g., magnetically, creating an anastomosis.

Systems, devices, and methods for endoscope or laparoscopic magnetic navigation

Various embodiments incorporate an 'end effector' in a magnetic anastomosis device system. The end effector is located between the handle of an endoscope or laparoscope and the distal end of the catheter. The end effector engages with and secures the magnetic anastomosis device assembly within a body lumen. The end effector is able to hold a magnetic device or devices with a tensile strength of 0-10 lbs. The end effector is small enough that two instruments of 1.8 mm diameter or smaller may be placed in a 3.7 mm working channel of an endoscope.

Systems, devices, and methods for endoscope or laparoscope magnetic navigation

Embodiments of the disclosure include methods and systems for attaching an articulation section. In an embodiment, a medical instrument includes a first tubular member including a first end. The medical instrument also includes a second tubular member including a first end. The second tubular member includes a plurality of layers including an inner layer and a first layer including a fluorinated material. The inner layer includes a first section disposed under the first layer and a second section extending out from under the first layer. A portion of the first tubular member overlaps and is bonded to at least a portion of the second section of the inner layer of the second tubular member.

Methods and systems for attaching medical device sections

A biopsy forceps device includes a tension member and an end effector including first and second jaws movable between an open configuration, in which the jaws are separated from one another to receive target tissue therebetween, and a closed configuration, in which cutting edges of the jaws are moved toward one another to cut a portion of the target tissue. The jaws define a tissue receiving space therebetween to house the cut tissue. The jaws are pivotable relative to one another, each of the jaws including a serrated cutting edge extending therealong, the end effector further including a tension member attachment including a proximal end coupled to the tension member. The attachment is movably coupled to the jaws so that distal movement of the attachment moves the jaws to the open configuration while proximal movement thereof moves the jaws to the closed configuration.

Biopsy forceps with serrated cutting jaws

A medical device may comprise a handle portion; an insertion portion having a proximal end portion at the handle portion, wherein the insertion portion includes a lumen therein and a distal end having a distal opening in communication with the lumen; and a member disposed within the lumen, the member having a distal end portion with an imaging device. The member may be configured to transition between a first configuration and a second configuration. In the first configuration, the imaging device may face distally, and, in the second configuration, the imaging device may face proximally. Extending the distal end portion of the member distally past the distal opening may cause the member to transition from the first configuration to the second configuration.

Devices for treatment of body lumens

According to one aspect, a guidewire assembly for positioning within a body of a patient may include a guidewire shaft having a proximal section and a distal section. The distal section may be configured to move within the body of a patient when the guidewire assembly is in a first operating state. The distal section may be configured to expand radially outward when the guidewire assembly is in a second operating state to engage an interior surface of the body and inhibit movement of the guidewire shaft.

Medical guidewires with controllable features

An endoluminal stent and associated methods for placing the endoluminal stent in a lumen of a trachea of a patient. The stent includes an elongate framework having a first open end, a second open end opposite the first open end, and a lumen extending from the first open end to the second open end. The elongate framework includes a first edge extending from the first open end to the second open end, a second edge extending from the first open end to the second open end, and an opening between the first edge and the second edge extending from the first open end to the second open end such that the stent has a C-shaped cross-section. The stent may be implanted in a trachea with the opening positioned along a posterior wall of the trachea adjacent the trachealis muscle.

Endoluminal stents and methods of delivery

Tracheal stents may include a plurality of wave form structures each extending radially about the support structure, a plurality of axial loop members extending axially between adjacent wave form structures and a polymeric covering disposed thereover. Tracheal stents may include an expandable metal structure and a plurality of spacer fins extending above an outer surface of the expandable metal structure. The plurality of spacer fins may be formed of a material different than that of the expandable metal structure.

Tracheal stent

This disclosure is directed primarily to a stent for use in the trachea. The stent has a nominally deployed state, an axially extended state and an axially compressed state. The stent has a length. In the axially extended state, the length is at least 20% greater than in the nominally deployed state.
