Provided is an expandable surgical access port having an arm mounting body defining an opening surrounding a longitudinal axis, a number of primary arms arranged around the longitudinal axis, a number of secondary arms arranged around the longitudinal axis, an activation ring rotatably mounted to the arm mounting body to pivot the primary and secondary arms from a closed position to an opened position, and a an expandable membrane extending along the primary and secondary arms. When arms are in the opened position, the expandable membrane has an elongated membrane cross-section as viewed along the longitudinal axis.

A device dimensioned to temporarily retract the foreskin of an uncircumcised penis to allow for the healing of an infection or disease affecting the skin of the glans of the penis, external urethral orifice and foreskin; and/or to treat at least one of phimosis and paraphimosis. The device may be configured to stretch and constrict as needed without creating too much pressure as to cut off circulation, and/or include non-elastic and/or elastic synthetic material. Device may be available at different sizes to the patient to ensure the best fit. Device may perform other foreskin manipulation procedures, such as pulling it forward as opposed to retracting the foreskin. The use of such device.

This disclosure relates to surgical planning systems, instrumentation and methods for modifying a patient anatomy. The planning systems and instrumentation disclosed herein may be utilized for placement of various surgical devices, including a guide member for establishing a position of another surgical device relative to the anatomy.

A surgical tool includes a drive housing, a shaft extending from the drive housing, wrist arranged at an end of the shaft and including a distal clevis, an axle mounted to the distal clevis, and first and second actuation pulleys rotatably mounted to the axle and rotatable about a pivot axis extending through the axle, each actuation pulley providing an actuation boss eccentric to the pivot axis, and an end effector operatively coupled to the wrist and including first and second blades pivotably coupled to the actuation bosses of the actuation pulleys. The blades are movable between open and closed positions by rotating the actuation pulleys such that the actuation boss of each actuation pulley remains proximal to a centerline of the axle, and movable to an over-centered position by rotating the actuation pulleys such that the actuation boss of each actuation pulley is located distal to the centerline.

A decompression surgery system includes an instrument shuttle configured to engage a first side of a target anatomical location, the instrument shuttle including a track. The system further includes a working channel configured to couple to and advance along the track of the instrument shuttle, the working channel having a distal end configured to engage a second side of the target anatomical location so that the target anatomical location is positioned between a portion of the instrument shuttle and the distal end of the working channel. The working channel is configured to receive one or more instruments therethrough.

A bone resection template includes a plate body and an extension arm extending from the plate body. The plate body has a length extending from a first end to a second end opposite the first end and the extension arm protrudes from the plate body proximate the second end. The extension arm includes a portion with a curved surface contoured to receive a bone therein such that when the bone is received on the curved surface portion the plate body is on one side of the bone.

An exemplary catheter for use in a body lumen comprises: a catheter body; and a plurality of shock wave emitters disposed at a distal end of the catheter body, each shock wave emitter configured to generate a shock wave that propagates distally of the catheter body, wherein the plurality of shock wave emitters are arrayed about a longitudinal axis of the catheter body such that shock waves emitted from the plurality of shock wave emitters can constructively interfere distally of the catheter body, and wherein each shock wave emitter comprises electrodes separated by a spark gap and at least one electrical connector that connects at least one of the electrodes to an electrode of another shock wave emitter of the plurality of shock wave emitters.

In accordance with at least one aspect of this disclosure, a flexible fastener includes, a shaft having a proximal end and a distal end spaced apart along a longitudinal axis and a land surface winding helically around the shaft. An interior pocket extends in an axial direction inside the shaft, radially inward from the land surface. A flexure opening extends through the shaft in the radial direction from the land surface to an inward facing surface of the interior pocket. The flexure opening extends helically about the longitudinal axis to provide for flexure of the shaft, of the land surface, and of the external thread. A torque driver is seated in the interior pocket, the toque driver having a torque face configured to abut a torque face of the interior pocket to develop toque along the shaft when a driving torque is applied to the proximal end of the shaft.

A surgical instrument includes an elongated body assembly adapted for being attached with a loading unit, wherein the loading unit may have various types. The elongated body assembly is provided with a loading unit type recognition portion that includes a first sliding member configured for being actuated by the loading unit during assembling of the loading unit, so as to be moved to a predetermined position; a first trigger member arranged on the first sliding member; a first circuit board, the first circuit board being provided with at least two first response members, and each first response member being configured to cooperate with the first trigger member to conduct or cut off one first electrical branch, and each of the first electrical branches may have a different load value; and a controller configured to determine the type of the loading unit according to a feedback signal from the first circuit board.

Disclosed herein are catheters for use with clot treatment systems, and associated devices and methods. The catheter can include an outer sheath, an outer sheath drive component operably coupled to the outer sheath, a guidewire sheath slidably disposed within the outer sheath, a guidewire sheath drive component operably coupled to the guidewire sheath and slidably disposed within the outer sheath drive component, and a clot treatment component. During a clot treatment procedure, the outer sheath drive component can be moved proximally and/or the guidewire sheath drive component can be moved distally to cause corresponding movement of the outer sheath and/or guidewire sheath, respectively, and transition the catheter between a first configuration, in which the clot treatment component can be positioned within the outer sheath, and a second configuration, in which at least part of the clot treatment component can extend beyond the outer sheath.
