604103030 | Having means to retain conduit or inflated means in position (e.g., depth control, external seal, etc.) | 7 |
20080294104 | Microcatheter Including Swellable Tip - A catheter for providing an embolic material at a desired location comprises a flexible tubular member having a proximal end and a distal end, the tubular member including at least one ring of expansible material affixed to its outer surface less than 25 mm from the distal end. The ring preferably comprises a material that expands in volume when in contact with a liquid, such as a hydrogel or hydrogel foam, or in response to an application of heat. The ring is fully expanded after between 10 and 30 minutes of contact with a liquid. The catheter may also include further including a plurality of radioopaque markers spaced along the tubular member at predetermined intervals. | 11-27-2008 |
20090221960 | BALLOON TROCAR ADVANCED FIXATION - A trocar cannula assembly can have a retention mechanism for advanced fixation. The retention mechanism can include a first, or distal balloon, and a second or proximal balloon to retain the position of the trocar cannula assembly with respect to a body wall of a patient. An inlet can be fluidly coupled to the retention mechanism via a fluid conduit so that the balloons can be selectively inflated and deflated. The retention mechanism can be coupled to the cannula, forming an integrated cannula assembly, or the retention mechanism can be removably attached to the cannula. Where the retention mechanism is removably attached to the cannula, it can include a double layer inflatable member with an outer layer including the first and second balloons, and an inner layer for retaining the cannula. | 09-03-2009 |
20100057000 | MALECOT WITH TEXTILE COVER - A malecot device includes a textile material covering its deployable malecot wing portion. The textile material is woven in a manner allowing it to be compactly disposed around an undeployed malecot and then expanded to cover malecot wings when those wings are deployed to an expanded outer device diameter. | 03-04-2010 |
20100106087 | SYSTEM AND METHODS FOR ENDOVASCULAR ANEURYSM TREATMENT - Embodiments provide methods and systems for treating aneurysms using filling structures filled with a curable medium. An embodiment of a method comprises positioning at least one double-walled filling structure across the aneurysm and filling the structure(s) with a filling medium so that an outer wall conforms to the inside of the aneurysm and an inner wall forms a generally tubular lumen to provide for blood flow. The lumen is supported with a balloon or other expandable device while and/or after filling. The pressure within the structure and/or in the space between an external wall of the structure and the aneurysm wall is monitored and a flow of the medium into the structure is controlled responsive to the pressure. The pressure can also be used to determine a filling endpoint. The medium is hardened while the lumen remains supported by the balloon. The balloon is then removed after the medium hardens. | 04-29-2010 |
20120109058 | INSERTION AID FOR MEDICAL DEVICES AND MEDICAL DEVICE USING THE INSERTION AID - Medical devices that are inserted into a body and that are used for treating a lumen inside a body sometimes use an insertion aid during insertion. However, there was a tendency for the relative positions of the insertion aid and the medical device to change, causing problems such as reduced operability and the insertion aid breaking the medical device during insertion. Disclosed are an insertion aid used by being placed within a medical device, and a medical device using said insertion aid. The insertion aid has a mechanism for holding said medical device from the inside, and said medical device uses said insertion aid, thereby making it possible to fix the relative positions of the insertion aid and the medical device when necessary. | 05-03-2012 |
20120150110 | CATHETER WITH VESSEL LINING AND METHODS FOR USING SAME - A system for providing access across a site of obstruction is provided. The system may include a sleeve, having a distal portion that can move from an inverted position to an everted position. A balloon situated within the sleeve can be extended so as to evert sleeve. A pathway can extend across a juncture between the distal portion and the remaining portion of the sleeve so as to provide access across the site of obstruction. A method for providing access across the site of obstruction is also provided. | 06-14-2012 |
