The present application discloses a device and methods for performing a vascular closure procedure that comprises inserting a sheath into a tissue tract defined in a body part and injecting a procoagulant material into the tissue tract adjacent a vascular access site via the sheath.

The invention relates to an accessory for implanting a medical device in a human or animal body, said medical device comprising an occlusion collar (1) adapted to surround and to seal an anatomical duct of said human or animal body, a fluid reservoir (2) and a tube (3) connecting the reservoir to the occlusion collar, said accessory comprising:—a plug (100; 100) adapted to seal an end of the tube; and—a collar (200) adapted to surround the tube, the plug (100) and the collar (200) having respective connection portions (103, 104; 203, 204) adapted to engage so as to fix the collar (200) and the plug (100) together so as to hermetically seal said end of the tube (3).

Devices, methods, and systems for closure device for a left atrial appendage and, in particular, to a closure device that includes an anchor element and a disc element that are each individually chosen based on the anatomy of the patient's left atrial appendage and assembled before implantation. In one embodiment, a medical device comprises: an anchor element, the anchor element including a first connection element; and a disc element, the disc element including a second connection element pivotably coupled to the first connection element, the anchor element being sized to be received and retained within a left atrial appendage and the disc element being sized to completely cover an opening of the left atrial appendage.

An ultrasound device includes an ultrasound body having a shaft and an ultrasound sensor assembly disposed at a distal end portion of the shaft. The ultrasound sensor assembly is configured to enable ultrasound imaging. A clip is configured for positioning about a portion of a surgical tool. The clip is configured to releasably engage the ultrasound body to thereby releasably couple the surgical tool with the ultrasound body. A surgical system includes the ultrasound device and the surgical tool.

Described herein are devices and methods for applying a tension force to various tissues. The devices may be delivered in minimally invasive fashion and used to manipulate tissues in the nose, ear, and throat. Force may be maintained by the devices for a time period that allows shaping, compression, or approximation of tissues.

A medical device to protect a body opening, such as a vagina. The medical device may include a lumen and anchoring structure(s) for securing the device in the body opening. In some embodiments, the medical device includes a sleeve, a proximal ring attached to a proximal end of the sleeve, and a distal ring attached to a distal end of the sleeve.

Provided herein are expandable devices, rail systems, and motorized devices. In one embodiment, an expandable device comprises an expandable sac having a tool housed therein. The expandable device is optionally configured for operation while inside a body cavity. The expandable device optionally comprises at least one rail in the sac, and at least one railed device coupled to the rail for movement there on. Movement of the railed device on the rail is provided by, for example, a motor such as an electromagnetic motor or an inch-worm type motor. Expandable devices can be used, for example, to perform minimally invasive medical procedures requiring access to a body cavity. Expandable devices can also be used, for example, to provide safe and stable transport of instruments to the body cavity.

Devices and methods for assisting valve function, replacing venous valves, and predicting valve treatment successes. In an exemplary embodiment of an endograft body configured for expansion within a luminal organ, the endograft body comprises (a) a first portion having a proximal end defining a proximal end aperture and a distal end defining a distal end aperture, the first portion configured to increase a velocity of fluid flowing therethrough, (b) a second portion having a second portion proximal end defining a second portion proximal end aperture and a second portion distal end defining a second portion distal end aperture, wherein the distal end of the first portion is adjacent to the second portion proximal end, and (c) a valve portion positioned at or near the second portion proximal end, the valve portion configured to receive the fluid flowing through the distal end aperture of the first portion.

A method of using an apparatus to protect the tissues, muscles and nerves of the female pelvic floor from trauma during vaginal childbirth, the apparatus having a softly expansible intravaginal component and a support component with a handle attached to the intravaginal component, the method including deploying the intravaginal device into a vaginal canal and under a fetal head in the vaginal canal during vaginal childbirth, attaching the handle device to the central body, and delivering fluid through the handle device into the intravaginal device and inflating the intravaginal device with the fluid to deploy the wings on the intravaginal device from the stored configuration into the deployed configuration to provide support and stabilization to at least one from among a perineal, perianal, and anal region and preventing or mitigating the subsequent development of abnormal fistulous communications between the vagina and either the urinary bladder or the rectum or both.

Systems, methods, and devices having improved conformal properties for biomedical signal measurement are disclosed. A device can have a first polymer substrate coupled to a conductive layer forming a conductive trace electrically coupled to a conductive pad exposed via an opening. The device can have a second polymer substrate forming a first cavity between the first polymer substrate and the second polymer substrate. The device can have a first inlet portion that receives a fluid that expands the first cavity causing the device to conform to an anatomical structure. The structure can be an atrium, such as the left atrium, of the heart of a patient. The device can conform to the walls of the tissue structure, and the conductive pad exposed via the opening can detect a signal from the wall of the tissue structure. The signal can be provided to an external measurement device for processing.
