Patent number: 9039748Abstract: A method for securing an implantable medical device onto a balloon which includes applying a coating, which includes a film-forming polymer and at least one solvent, to the outer surface of the balloon. The solvents can include alcohol, water, ether and combinations thereof. The film-forming polymer can include a zwitterionic polymer, such as, for example a phosphorylcholine polymer. The coating can be applied to the entire balloon surface or a portion of the surface. The implantable medical device is then positioned on the outer surface of the balloon and secured. The film-forming polymer is then allowed to cure in order to define an adhesive layer between an inner surface of the implantable medical device and the outer surface of the balloon. This method prevents or reduces the leaching or redistribution of any therapeutic agents dispersed within or on the surface of the implantable medical device.Type: GrantFiled: April 7, 2009Date of Patent: May 26, 2015Assignee: Abbott Cardiovascular Systems Inc.Inventors: Keith R.

Patent number: 8992562Abstract: A filter delivery device for implanting a vessel filter within a blood vessel of a patient's body. The filter delivery device includes a mechanism for preventing hooks and/or legs on a vessel filter from entangling with each other while the vessel filter is loaded within the delivery device. In one variation, the filter delivery device includes a delivery catheter with grooves at the distal end lumen opening. When a vessel filter with radially expanding legs is compressed and inserted into the distal end of the delivery catheter, the hooks on the distal end of the legs are received and separated by the corresponding grooves on the delivery catheter. In another variation, a pusher rod, with a receptacle for receiving the hooks, is positioned within a delivery catheter to prevent the entanglement of the hooks and/or legs of a filter loaded within the delivery catheter.Type: GrantFiled: September 13, 2010Date of Patent: March 31, 2015Assignee: C.R. Bard, Inc.Inventors: Alexander W. Tessmer, David G. Spilka, David W. Rauch, Andrzej J. Chanduszko, Robert M. Carr, Jr.

Patent number: 8568436Abstract: A dilator (10) for creating tracheostomies in one pass. Dilator (10) includes a generally linear shaft (12) extending from a proximal end (14) and beginning at a distance therefrom, gradually and continuously through a curved distal portion (16) of continuously decreasing diameter (from about 38 french) to a distal tip portion (18) of small diameter of about 12 french at distal end (20). The outer surface of the insertable portion is treated or hydrophilically coated to minimize friction, and the gradual taper gradually widens the tracheal entrance opening (44) between tracheal rings (46,48) with minimal trauma. The wall thickness gradually decreases from the linear shaft (12) to the soft distal tip portion (18). The continuing curve of the distal portion (16) enables the increasingly longer inserted portion of the dilator to remain situated in the trachea (50) during insertion and for the distal tip portion to clear the posterior tracheal wall.Type: GrantFiled: August 29, 2003Date of Patent: October 29, 2013Assignee: Cook Medical Technologies LLCInventors: Pasquale Ciaglia, Melodee Deckard, Mark J.
