Unitary endoscopic vessel harvesting devices are disclosed. In some embodiments, such devices may comprise an elongated body having a proximal end and a distal end. A conical tip may be disposed at the distal end of the elongated body. In addition, the surgical instrument may include one or more surgical instruments moveable in a longitudinal direction along an axis substantially parallel to a central longitudinal axis of the cannula from a retracted position proximally of a distal end of the tip to an advanced position toward the distal end of the tip to seal and cut a blood vessel.

A catheter device with a cutting structure or means on the distal portion is disclosed, along with a medical procedure for using the device. The catheter is configured in such a way as to create a permanent interatrial aperture in the heart, including creating a permanent interatrial hole and/or removing tissue.

A blood vessel dissecting device is disclosed, which includes a dissecting device configured to be inserted into a living body along a blood vessel to dissect tissue surrounding the vessel from tissue surrounding the vessel in a direction along a longitudinal extent of the blood vessel; and a cutting device configured to fee inserted into the living body along the longitudinal extent of the blood vessel to cut the tissue surrounding the blood vessel so the direction of longitudinal extent of the blood vessel.

Devices and methods for tissue removal are disclosed herein, including those in which a powered rotary tool actuates a cutting blade to sever tissue and drives an auger to transport the severed tissue proximally through the device. The severed tissue can be collected in an on-board collection chamber for subsequent use as graft material or otherwise (e.g., assay, analysis, post-processing, etc.). Devices of the type disclosed herein can reduce or eliminate the need to move the device in and out of the surgical site, reduce user input force, and provide improved ergonomics and increased user focus.

A surgical console includes a drive assembly, vacuum interface, fluid transfer device, user interface, and control circuit. The drive assembly is configured to be coupled to an endoscopic tool and to be rotated by a motor. The vacuum interface is configured to apply a vacuum to the endoscopic tool. The fluid transfer device is configured to flow fluid through the endoscopic tool. The user interface is configured to receive a user input indicating at least one of instructions to rotate the endoscopic tool while applying the vacuum, or to flow fluid through the endoscopic tool. The control circuit controls at least one of the drive assembly, the vacuum interface, or the fluid transfer device based on the instructions, and is configured to cause the drive assembly to rotate the endoscopic tool while the vacuum interface applies the vacuum responsive to the user input indicating instructions to rotate the endoscopic tool.

A biopsy device comprises a coring and transport assembly and a distal beak assembly. The distal beak assembly may be coupled to or near a distal end of the coring and transport assembly and may comprise at least one movable cutting element. The distal beak assembly may be configured to rotate about an axis, and assume at least a first open configuration operative to enable the at least one cutting element to core through tissue and a second closed configuration operative to enable the at least one cutting element to move through the tissue and to sever a cored specimen from the tissue.

An endoscopic surgical device having a slotted clear cannula, a blade and a housing, wherein the cannula is attached to the housing, and wherein the blade is enclosed in the housing and is slidable into the cannula is disclosed. The blade is enclosed within the housing and cannula, and has a horizontally-oriented pushing component and a vertically-oriented cutting component that protrudes through the slot of the cannula. The device further has a device for locking a viewing device in place relative to other components of the device. A method for a performing an operative procedure on a target tissue in a subject using the endoscopic surgical device is also described.

There is disclosed, among other things, embodiments of a biopsy needle for taking a full core sample through soft tissue. In the illustrated embodiments, the needle includes a single monolithic tubular member having a notch cut part-way through a distal portion of the tubular member to form an arch-shaped finger. At least a portion of the finger is bent toward the notch and into the lumen of the tubular member. Methods for using these embodiments are also described.

The present devices and methods relate generally to vacuum or suction powered medical devices and methods for cutting, resecting, excising, morcellating and/or evacuating tissue from various regions of a patient's body. In certain variations, the devices may produce a rotational motion by converting a linear reciprocating motion to a rotational motion, causing a cutting shaft or other tool to rotate to perform work on a tissue in various regions of the body.

An automated control, a switch and automated actuator for spring-based end effectors of a medical instrument to be used by a single operator without assistance for multiple biopsy, clipping, clamping, grasping, snaring, cutting, dissecting or other operative functions with electrical connections for cautery or hot biopsy used independently or combined with a rigid or flexible endoscope of any size. The actuator may be a spring(s), gear(s), electrical solenoid or motor, air or hydraulic pressure activated piston or a combination thereof. Automated action may be initiated by a voice, hand or foot operated switch. The actuator may be disposable, attached to or separable from the end effector or permanently attached to be reusable. The actuator and end effector may be disposable, attached to or separable from the endoscope or permanently attached to be reusable. The automated device may be incorporated into an endoscope or attached to the outside.
