A method for removing one or more objects or materials from a body lumen includes delivering a tube and an expandable device to the body lumen to a position proximal to the one or more objects or materials. The expandable device is positioned with a lumen of the tube, and the expandable device includes a lumen extending from a distal portion to a proximal portion. The method further includes proximally retracting the tube such that the expandable device remains in the position proximal to the one or more objects or materials, distally advancing the expandable device such that the distal portion of the expandable device at least partially surrounds the one or more objects or materials, at least partially closing a distal end of the expandable device, and moving the expandable device proximally to remove the expandable device and the one or more objects or materials from the lumen.

An expandable clot mobilizer device for extraction of an occlusion from a blood vessel is provided, which comprises a working portion including a plurality of crowns of cells. Each cell comprises an open area bordered by two proximal cell struts, two distal cell struts, and two middle cell struts. The proximal cell struts each extending distally from a common proximal end to a proximal end of a respective one of the two middle cell struts, the distal cell struts each extending proximally from a common distal end to a distal end of a respective one of the two middle cell struts, each middle cell strut in each crown bordering two adjacent cells in that crown and each middle cell strut being adapted and configured to be more flexible than the distal cell strut and the proximal cell strut to which it extends. The clot mobilizer also comprises a tapered portion.

A self-expandable medical device for advancement through vasculature to an expansion site in a blood vessel is disclosed. The device comprises a working portion and a connection portion that can be connected to a pusher. The working portion provides an outward radial force at every diameter between and including the diameter of a compressed and an expanded configurations, and comprises a plurality of crowns of cells comprising an open area bordered by two proximal cell struts, two distal cell struts, and two middle cell struts. The proximal cell struts each extend distally from a common proximal end to a proximal end of a respective one of the two middle cell struts. The distal cell struts each extend proximally from a common distal end to a distal end of a respective one of the two middle cell struts. Each middle cell strut is more flexible than the distal cell strut and proximal cell strut to which it extends.

Described herein is a patch delivery assembly for treating a target site and a method for deploying the same. The patch delivery assembly includes a patch installation frame having a self-expanding body extending between a proximal end and an open distal end and defining a lumen therethrough. The patch delivery assembly also includes a delivery cable having a distal end coupled to the proximal end of the patch installation frame and further defining the lumen, and a securement device extending through the lumen defined through the delivery cable and the patch installation frame, the securement device terminating in a distal working end including a securement mechanism. In a deployment configuration of the patch delivery assembly, the patch delivery assembly further includes a patch releasably coupled to the distal end of the patch installation frame, for securement to tissue of the target site using the securement mechanism.

An arterial plaque treatment system includes a drilling member having a proximal end and a distal end, the distal end comprising a drilling mechanism; a locator member having a proximal end and a distal end, the locator member having a lumen sized and shaped to receive the drilling member therein and having a locating mechanism at the distal end, the locating mechanism being moveable between a first position and a second position; and an arterial plaque treatment tool, wherein the locator member is adapted to be advanced in an artery to a position in proximity to an arterial plaque buildup while the locating member is in the first position and then is adapted to position the drilling member at a desired position relative to the arterial plaque buildup when the locating mechanism is moved to the second position. In another version, an atherectomy device is inserted into the arterial plaque through the locator member. A method of treating arterial plaque is also provided.

A surgical instrument includes a base body detachable from a surgical robot arm, a support body connected to the base body, and first and second jaws. The first jaw is rotatably supported on a first shaft supported by the support body and includes a first opening pulley, a first closing pulley, and a first blade part. The second jaw is rotatably supported on the first shaft and includes a second opening pulley, a second closing pulley, and a second blade part. The first opening pulley is axially separated from the first closing pulley and the second opening pulley is axially separated from the second closing pulley. An axial direction of the first shaft is orthogonal to an opening and closing direction of the first blade part and the second blade part.

A medical device, comprising a catheter comprising an end-effector, wherein the end-effector further comprises a proximal portion; and a flexible distal portion, wherein the distal portion further includes a window formed therein; and a flexible ultrasonic waveguide disposed within the end-effector, wherein the waveguide includes an active zone that extends through the window; and a mechanism for bending the waveguide, bending the distal portion, or bending both the waveguide and the distal portion, wherein the mechanism permits desired positioning of the waveguide within a lumen.

There is provided a method for controlling a flow of sperms in a uterine tube of a female patient. The method comprises electrically stimulating a uterine tube wall portion by controlling an implanted stimulation device from at least one of an external control unit and an internal control unit, wherein the electrically stimulating causes contraction of the uterine tube wall portion along a length of the portion to restrict the flow of sperms in the uterine tube.

There is provided a method for controlling the movement of bile and/or gall stones in the biliary duct. The method comprises gently constricting (i.e., without substantially hampering the blood circulation in the tissue wall) at least one portion of the tissue wall to influence the movement of bile and/or gallstones in the biliary duct, and stimulating the constricted wall portion to cause contraction of the wall portion to further influence the movement of bile and/or gallstones in the biliary duct. The method can be used for restricting or stopping the movement of bile and/or gallstones in the biliary duct, or for actively moving the fluid in the biliary duct, with a low risk of injuring the biliary duct.

A cutting head for use with an intramedullary reamer is described. The reamer cutting head is of a unitary body construction that comprises a conically-shaped body having a bone cutting portion spaced from a barrel portion for attachment to a drive shaft. The bone cutting portion comprises a plurality of blades having a tissue cutting edge that outwardly extends from the cylindrical body. The plurality of blades is positioned about the cutting head in a spaced apart manner. The various plurality of blades are arranged at prescribed angular relationship that increases cutting efficiency and debris removal, thereby reducing reactive torque, axial loading, and head pressure during a surgical procedure.
