Mechanical thrombectomy apparatuses, and particularly knitted rolling tube mechanical thrombectomy apparatuses configured to have improved tracking for delivery through tortious vessels are described herein. Also described herein are methods of removing clots using a mechanical thrombectomy apparatuses in which the clot is larger than the tractor portion of the mechanical thrombectomy apparatus.

Mechanical thrombectomy apparatuses (devices, systems, etc.) and methods for positioning them within a vessel and using them to remove a thrombus, e.g., clot, from within a vessel. In particular, described herein are methods of advancing an inverting tractor thrombectomy apparatus having a tractor comprising a flexible tube of material that inverts over itself as it rolls over a distal end opening of an elongate inversion support by extending the tractor region and/or a puller coupled to the tractor distally beyond the end of the catheter. Also described herein are power-driven mechanical thrombectomy apparatuses.

Devices for removing clot material from a blood vessel lumen and associated systems and methods are disclosed herein. A clot retrieving device may include, for example, an elongated shaft, a capture structure having a proximal portion and a distal portion, and a cover having a first portion coupled to the elongated shaft and a second portion extending from the first portion. The cover may have an inverted configuration in which the capture structure is at least partially ensheathed within the first portion of the cover and the second portion of the cover extends distally from the first portion. In the inverted configuration, the second portion may have (a) a first region distal to a distal terminus of the capture structure, the first region tapering radially inwardly in a distal direction, and (b) a second region extending distally and radially outwardly from the first region.

Described herein are mechanical inverting tube apparatuses that may be used to remove clot (e.g., thrombectomy), the apparatuses including an inversion support catheter having an expandable funnel-shaped distal end, and a flexible tube that can be continuously rolled over the funnel-shaped distal end and invert into the inner lumen of the inversion support catheter.

The invention relates to a tissue receiving bag for use in surgery, especially laparoscopic surgery, wherein the bag comprises at least one tissue receiving opening for receiving tissue and/or an instrument opening, especially a morcellator opening, wherein the bag comprises at least one further opening into the bag, wherein a flexible tube extends from said further opening having a free end comprising an insertion opening for inserting an instrument into the bag, wherein the bag preferably is inflatable.

Everting balloon systems and methods for using the same are disclosed herein. The systems can be configured to access and dilate body lumen and cavities. For example, the systems can be used to dilate the cervix and access the uterine cavity. The systems can also be used to occlude the cervix. The systems can also be used to occlude the urethra.

A trocar system with a trocar which has a trocar mandrel, a trocar sleeve and a valve block, characterized by a tubular working sleeve having an axially continuous inner channel, in which the trocar can be inserted in such a way that the trocar sleeve is sealed with the outer perimeter thereof in the inner channel, so that the distal tip of the trocar mandrel projects distally out of the working sleeve and that the valve block is located proximally outside the inner channel, and having at least one working channel which is formed on the working sleeve and extends from a proximal inlet opening to a distal outlet opening.

Method and system for treating a patient using a compressible, pressure-attenuating device. According to one embodiment, the system is used to treat urinary tract disorders and comprises an access device, a delivery device, a pressure-attenuating device, and a removal device. The access device may be used to create a passageway to an anatomical structure, such as the patient's bladder. The delivery device may be inserted through the passageway created by the access device and may be used to deliver the pressure-attenuating device to the anatomical structure. The removal device may be inserted through the passageway created by the access device and may be used to view the bladder and/or to capture, to deflate and to remove the pressure-attenuating device.
