20090043249 | Tisssue prosthesis processing technology - A heart valve prostheses crimping apparatus and method for deducing the diameter of stents containing heart valve prosthesis. A medical prosthesis catheter loading apparatus, including a crimping assembly for reducing the diameter of a prosthesis; and a catheter clamp for holding a catheter adjacent to the prosthesis. Also disclosed is an apparatus for reducing the diameter of a medical prosthesis, including a base, a crimp head connectable to the base, and an actuation mechanism connected to the base and connectable to the crimp head to actuate the crimp head. Also disclosed is a method of loading a medical prosthesis into a catheter, including the steps of reducing the diameter of a prosthesis from its normal deployed state to a diameter less than that of the lumen of the catheter; holding a catheter adjacent to the reduced diameter prosthesis; and moving the prosthesis into the catheter lumen. | 02-12-2009 |
20090049675 | Method and apparatus for cold loading articles - A method of loading an article, such as a self-expanding stent, into a structures such as a delivery catheter, including the steps of chilling the article to a predetermined temperature, reducing article size a predetermined amount, inserting fluid into the article, whereby the fluid forms a substantially solid plug with respect to the article, and moving the frozen article. Also provided is an apparatus for loading an article into a structure including: an article size reduction element, a chiller connected to the size reduction element, a cold source communicatively connected to the chiller, and a fluid supply communicatively connected to the size reduction element. | 02-26-2009 |

20100211052 | FORCED DEPLOYMENT SEQUENCE - A fixed sequence activation handle is described that forces a predetermined activation sequence. Such handles are suitable for use in the delivery of medical devices or for other application that require a fixed sequence of activations. | 08-19-2010 |
20120046652 | FORCED DEPLOYMENT SEQUENCE HANDLE ASSEMBLY WITH INDEPENDENT ACTUATING MECHANISM - A handle assembly for use in the deployment of a medical device via a plurality of deployment lines that extend through a catheter. The handle assembly includes a plurality of removable members for deployment or actuation of the medical device. The handle assembly also includes an actuating mechanism for displacing a wire extending through the catheter for actuating the medical device independently of the plurality of removable members. | 02-23-2012 |
20120143302 | MEDICAL APPARATUS AND METHOD OF MAKING THE SAME - A catheter assembly includes a catheter having a proximal end and a distal end; an expandable device releasably attached to the catheter near the distal end; a generally tubular constraining sleeve extending around and compressing the device to an outer peripheral dimension suitable for endoluminal delivery; a tip fixedly secured to the distal end of the catheter; and a bridge member disposed between the tip and the expandable device so as to fill a gap therebetween as the catheter assembly is bent during endoluminal delivery of the expandable device to a treatment site. | 06-07-2012 |
