Abstract: According to one aspect, a medical system may include an instrument including an end effector for acting as a monopolar electrode. The end effector may be configured to be positioned in a body of a subject and emit radiofrequency energy towards a target area in the body. The medical system may further include a return electrode. The return electrode may be deliverable within the body proximate the target area and separately from the instrument and the monopolar electrode. The return electrode may be configured to contact tissue in the body proximate the target area and receive radiofrequency energy emitted from the end effector.

Abstract: Devices, systems and methods for treating diseases and disorders effecting the cardiovascular system of the human body are disclosed. An exemplary device in accordance with this disclosure comprises a shaft, tip member fixed to the shaft, and a probe extending beyond a distal surface of the tip member. In some useful embodiments, the tip member is relatively atraumatic and the probe is shaped so as to be more likely to produce trauma than the tip member.

Abstract: A device for fastening tissue includes (a) a shaft extending longitudinally from a distal end insertable into a body to a proximal end attached to a controller which remains outside of the body, the shaft including a lumen extending therethrough and an opening extending through a wall of a distal portion thereof to open the lumen to an exterior of the shaft; (b) a first roller housed within the lumen adjacent to a first longitudinal edge of the opening such that a rotation of the first roller grasps and draws tissue from the body into the lumen in combination; and (c) a fastening element housed within the lumen adjacent to the opening and movable from a tissue receiving configuration to a tissue gripping configuration.

Abstract: The present disclosure relates to the field of tissue dissection. Specifically, the present disclosure relates to medical devices that lift and retract tissue during a dissection procedure to improve visualization of the target tissue and mitigate obstructions for dissection tools. In particular, the present disclosure relates to devices that transition from a constrained to an unconstrained bowed configuration to immobilize and retract the dissected portion of target tissue during a dissection procedure.

Abstract: Example medical device loading devices are disclosed. An example loading device for a stent-valve includes an elongated body having a proximal end region, a distal end region and a lumen extending therein. The loading device also includes a collar coupled to the distal end region of the body, the collar including first end region, a second end region and a lumen extending therein. Further, the loading device includes a first compression assembly coupled to the collar, wherein the first compression assembly is configured to shift between a first position a second position. The loading device also includes a second compression assembly coupled to the collar, wherein the second compression assembly is configured to shift between a third position and a fourth position.

Abstract: A device for compressing body tissue includes a clip having a connection portion with first and second clip arms extending therefrom, the clip includes a recess formed on an inner surface of the connection portion, the recess being shaped and sized to slidably receive a mounting bar coupled to an outer surface of an endoscope on which the mounting bar is mounted with inner surfaces of the first and second clip arms maintained in an open position by contact between an endoscope on which the mounting bar is mounted and the inner surfaces of the first and second clip arms. The clip is slidable over the outer surface of an endoscope on which the mounting bar is mounted until the clip moves distally beyond the distal end of the endoscope so that the first and second clip arms spring closed to grip tissue therebetween.

Abstract: Features for a restraint, such as a cap, are described. The restraint secures a cardiac device in a collapsed, delivery configuration for transcatheter delivery to a heart. The restraint may have a tubular sidewall extending from a proximal end to a distal end, a proximal opening defined by the sidewall at the proximal end and a channel defined by the sidewall and extending distally from the proximal opening. The restraint is configured to receive the implant in the collapsed configuration through the proximal opening to radially restrain the implant within the channel. The restraint eliminates the need for a surrounding sheath, reducing the delivery profile and size of the overall delivery system, among other advantages. The restraint may have an atraumatic leading edge to reduce the risk of injury to the patient.
