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.

A hollow rod developable actuator tool including a first link comprising an outer cylinder, a second link comprising a first tool member pivotably connected to the first link at a first joint mounted in a first cavity in the wall of the outer cylinder, a third link comprising a second tool member pivotably connected to the first tool member at a second link, and a fourth link comprising an inner cylinder to which the second tool member is also pivotably connected at a third link mounted in a second cavity in the wall of the inner cylinder. When the inner cylinder of the fourth link is rotated in relation to the outer cylinder of the first link the actuator tool transitions from a first state where the tool is closed to a second state where the tool is open.

A method for removing tissues may comprise disposing a tissue resection device at a target tissue site, causing the tissue resection device to resect a core of tissue from the target tissue site, removing the core of tissue from the body, wherein the removing the core of tissue from the body creates a core cavity at the target tissue site.

A biopsy needle assembly configured for use with a tissue biopsy device is disclosed. The biopsy needle assembly may be configured to be advanced to a predetermined tissue sample, sever the tissue sample, and extract the tissue sample from a body tissue of a patient. The biopsy needle assembly may be further configured with two or more cooperating members configured to sever a sample.

A method treating a deficient native mitral valve includes advancing the distal end portion of a delivery catheter into a heart, wherein the delivery catheter contains a support band stretched into a linear form, wherein the support band comprises a shape-memory material, and then ejecting the support band from the distal end portion of the delivery catheter such that the support band transitions from the linear form to a curved shape extending around native leaflets of the native mitral valve.

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.

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.

A surgical cutting tool with a body having a proximal end and a distal end; a cannula rotatably extending from the distal end of the body, the cannula having a proximal end and a distal end; a cutting head removably coupled to the distal end of the cannula, the cutting head having a distal tip and a cutting window; a hollow shaft movably positioned inside the cannula, the hollow shaft having a blade; a suction connector in fluid communication with the hollow shaft, the suction connector being configured for connection to a suction source; a suction control configured to alter suction from the suction connector to the hollow shaft; and an actuator coupled to the hollow shaft for moving the blade of the hollow shaft relative to the cutting window of the cutting head.

Surgical cutting apparatus (1) for removal of human tissue tumour. The apparatus (1) comprises a first knife (2) with a circular shaped side wall (5) comprising a cutting edge (6). The first knife (2) being arranged for cutting tissue in a first direction (7). The apparatus (1) comprises a shank (8), wherein the shank (8) has a width (w) of less than 15 millimetres. The first knife (2) has a height (h) of less than 15 millimetres. The shank (8) being a yoke comprising two legs (8a, 8b) interconnected at their respective second shank ends (10a, 10b). The apparatus (1) permitting removal of human tissue tumour by firstly bringing the first knife (2) under the skin through a narrow incision, and secondly cutting the tissue in the first direction (7) axially with the first knife (2), by an axially pressing and rotating movement of the first knife (2).

A method of obtaining a tissue specimen includes moving a biopsy needle through a vasculature and through a wall of a blood vessel at a target site. At the target site, the biopsy needle forms a puncture through a wall of said blood vessel at a non-perpendicular angle so that an inner-wall opening of the puncture is further downstream from an outer-wall opening of the puncture. The biopsy needle resects a portion of tissue. The biopsy needle reenters the puncture with the portion of the tissue trapped therein. The biopsy needle is withdrawn from the vasculature for subsequent inspection of the tissue.
