Implants comprising electrically-responsive hydrogel are described. Systems to provide electricity to induce response in hydrogel-containing implants are described. Methods for utilizing said system and methods for utilizing said hydrogel-containing implants are described.

Retrieval of material from vessel lumens can be improved by use of a distal element comprising an expandable mesh. a treatment device includes an elongated member having a proximal portion and a distal portion configured to be positioned within a blood vessel at a treatment site at or near a thrombus. A distal element comprising an expandable mesh is coupled to the distal portion of the elongated member via a connection assembly. In an expanded state, at least a portion of the mesh is configured to be in apposition with the blood vessel wall at the treatment site to anchor or stabilize the elongated member with respect to the blood vessel. The distal element can be electrically coupled to an extracorporeal current generator.

Retrieval of material from vessel lumens can be improved by electrically enhancing attachment of the material to the thrombectomy system. The system can an interventional element configured to be delivered to a treatment site and to be electrically coupled to an extracorporeal power supply. The interventional element can be surface treated (e.g., via electrochemical anodization) to achieve a desired electrical conductivity gradient over the surface of the interventional element. The electrical conductivity gradient can result in a more desirable surface charge distribution upon delivery of electrical current to the interventional element.

A safe, practical, method for physical removal of a fecal impaction. This device empowers the clinical community to treat persons' who suffers from the painful condition in a more compassionate way without the fear of causing more harm to the patient.

A medical device, configured to perform an endovascular therapy, e.g., thrombectomy, can comprise an elongate manipulation member having a first connection member proximate a distal end of the elongate manipulation member, and an intervention member having a second connection member proximate a proximal end of the intervention member. The second connection member can be connected to the first connection member such that the first connection member can rotate relative to the second connection member.

Aspects of a device are described. One aspect is a device comprising: a housing having a first portion engageable with a scope, and a second portion engageable with a handle of a retrieval device; a platform that is movable relative to the housing, and engageable with a slider of the retrieval device; and a link assembly that is coupled the housing and the platform, and operable to move the platform and slider relative to the housing and handle. Aspects of related devices and systems also are described.

The present invention relates to devices and methods for separating tissues to create an anatomical access space in the body, in particular, for providing an access to the space between the pericardium and the epicardium.

Intraluminal devices and methods for removing an obstruction from a blood vessel using an intraluminal device are provided. The intraluminal device can include a flexible shaft and an expandable wire mesh structure extending from the flexible shaft, the wire mesh structure including at least one first expandable section having a first wire arrangement pattern and at least one second expandable section having a second wire arrangement pattern different from the first wire arrangement pattern. In addition, interstices in the at least one second expandable section.

A system for retrieving material from a cavity in a patient may include a tube having a proximal end and a distal end, the scope configured to be inserted into the cavity, and a filter assembly disposed between the tube and a vacuum source configured to apply negative pressure through the tube to cause the material to flow through the tube from the distal end to the proximal end, the filter assembly including a filter configured to trap the material in the filter assembly, and allow liquid and gases to pass through the filter assembly.

A treatment tool for an endoscope includes an elongated cylindrical flexible sheath, an operation wire inserted into a cylinder of the flexible sheath and movable forward and backward in an axial direction within the cylinder by being operated to be pushed and pulled, a treatment unit provided in a distal end of the operation wire and performing treatment of an affected area, an operation unit for operating the operation wire to move forward and backward, and a liquid injection unit arranged between the flexible sheath and the operation unit and including a liquid injection port for supplying liquid to the treatment unit. The liquid injection unit and the operation unit are connected by screw fastening, and a locking mechanism is provided for temporarily fixing the screwed state, thereby preventing a screwed portion between the operation unit and the connection unit from being loosened and disconnected by rotational operation during treatment.
