20090074943 | MICRODROP ABLUMENAL COATING SYSTEM AND METHOD - Systems and methods for coating medical devices are provided that allow for relatively precise control over the deposition area and coating uniformity with improved efficiency. A microdrop source is used to provide a flow of coating microdrops. A charging electrode disposed near the outlet of the coating source gives each microdrop an electrostatic charge. As the microdrop travels toward the medical device to be coated, a control electrode alters the trajectory of the microdrop. The invention can include a scanner to scan or image the medical device as the coating is applied and a control system to adjust parameters of the deposition process based on information provided by the scanner. | 03-19-2009 |
20120160408 | Composite ePTFE- Silicone Covering for Stent - A medical device consists of a stent having a first surface and a second surface parallel to the first surface; a single expanded polytetrafluoroethylene (ePTFE) layer contacting the first surface of the stent; and an elastomeric layer applied to at least one surface of the stent. In at least one embodiment, the elastomeric layer is silicone. In at least one embodiment, the medical device is manufactured by positioning the ePTFE layer such that a first surface of the ePTFE layer contacts a first surface of the stent to form a stent-ePTFE assembly; and applying an elastomeric solution to the first surface of the ePTFE layer and at least one surface of the stent. | 06-28-2012 |
20140121747 | STENT HAVING A TACKY SILICONE COATING TO PREVENT STENT MIGRATION - A stent having an inner surface and an outer surface, at least a portion of the outer surface of the stent comprising a tacky biocompatible coating comprising a tacky polymer material and to methods of delivering and deploying a stent using a tacky biocompatible coating comprising a tacky polymer material. | 05-01-2014 |
20150045875 | ATRAUMATIC STENTS INCLUDING RADIOPAQUE CONNECTORS AND METHODS - The invention is directed to a stent including at least one member having a first portion and a second portion and at least one radiopaque connector joining the first portion to the second portion. In one or more embodiments, at least one radiopaque connector may form a first radiopaque pattern distinguishable from a second radiopaque pattern formed by at least one radiopaque marker. Methods for manufacturing a stent including at least two member portions connected by at least one radiopaque connector are also provided. | 02-12-2015 |
20150045876 | DISSOLVABLE OR DEGRADABLE ADHESIVE POLYMER TO PREVENT STENT MIGRATION - A stent having an inner surface and an outer surface, at least a portion of the outer surface of the stent comprising a dissolvable adhesive polymer or a degradable adhesive polymer disposed on at least a portion of the outer surface of the stent, the adhesive is activated by exposure to an aqueous environment, the dissolvable adhesive polymer dissolves over time in an aqueous environment, the dissolvable adhesive polymer or the degradable adhesive polymer has a surface tack of about 2 psi to about 14 psi. | 02-12-2015 |
20150068676 | Composite ePTFE- Silicone Covering for Stent - A medical device consists of a stent having a first surface and a second surface parallel to the first surface; a single expanded polytetrafluoroethylene (ePTFE) layer contacting the first surface of the stent; and an elastomeric layer applied to at least one surface of the stent. In at least one embodiment, the elastomeric layer is silicone. In at least one embodiment, the medical device is manufactured by positioning the ePTFE layer such that a first surface of the ePTFE layer contacts a first surface of the stent to form a stent-ePTFE assembly; and applying an elastomeric solution to the first surface of the ePTFE layer and at least one surface of the stent. | 03-12-2015 |
20150342770 | CATHETER WITH RADIOFREQUENCY CUTTING TIP AND HEATED BALLOON - Methods for draining pseudocysts and stent delivery systems for use therein are disclosed. An illustrative system may include a catheter shaft having an inflatable balloon affixed to a distal end region thereof. A cutting electrode may be disposed at the distal end of the system and at least one heating electrode may be disposed within the inflatable balloon. A self expandable stent may be disposed about the inflatable balloon. The stent may be formed of a shape memory polymer. The inflation fluid may be heated within the balloon to facilitate expansion of the stent. | 12-03-2015 |
20150342834 | GASTROSTOMY DEVICE WITH CONTROLLED SHAPE SILICONE BALLOON - A gastrostomy device includes an elongate tube extending from a proximal end to a distal end and having a tube diameter. The elongate tube has a length that enables the elongate tube to extend from a position exterior a patient to a position interior the patient's stomach. A resealable valve is disposed within the proximal end of the elongate tube. An inflation lumen extends along the elongate tube and an inflation port is disposed near the proximal end of the elongate tube and is in fluid communication with the inflation lumen. A silicone balloon is secured relative to the distal end of the elongate tube and is in fluid communication with the inflation lumen. The silicone balloon has a distal region, a proximal region and an intervening middle region that, when inflated, stretches more than the distal region or the proximal region. | 12-03-2015 |
