20140217136 | Holster Mechanism - Holster mechanism techniques are described. In one or more implementations, an apparatus comprises a holster configured to secure a device, a hood connected to the holster, and a locking mechanism. The hood comprises a biasing portion configured to receive a force to cause the hood to move between a closed position and an open position. The locking mechanism comprises a first locking portion and a second locking portion configured to engage the first locking portion to secure the hood in the closed position or the open position. | 08-07-2014 |

20150051634 | AORTIC OCCLUDER WITH TENSIONED BALLOONS - An aortic occluder catheter with expandable balloons for increasing cerebral blood blow has one or more balloons on a catheter shaft. To assist the balloon in bearing up against arterial blood flow while positioned retrograde in the aorta, the balloon is bonded to the catheter shaft in tension. | 02-19-2015 |
20150051635 | AORTIC OCCLUDER WITH STRENGTH BONDED BALLOONS - An aortic occluder catheter with expandable balloons for increasing cerebral blood blow has one or more balloons on a catheter shaft. To assist the balloon in bearing up against arterial blood flow while positioned retrograde in the aorta, the balloon is bonded to the catheter shaft using heat shrink tubing and a thermal bonding machine and then further ironed using a second piece of heat shrink tubing and a second heating process. | 02-19-2015 |

20150173898 | Transcatheter Mitral Valve Replacement Apparatus - Transcatheter mitral valve replacement is provided which includes a stabilizing stent portion for placement at a mitral annulus, with a narrowed waist portion to avoid significantly dilating the annulus, and expanded bulb portions at the atrial and ventricular ends to secure the device in position. A housing is attached to the stabilizing stent and reduces in diameter to a smaller tract portion where replacement valve leaflets are secured. The resulting smaller replacement mitral valve offers benefits including a lower introduction profile, yet fits and secures to the native annulus by the securing stent and housing. Expansion limiting elements can limit expansion of portions of self-expanding stent if desired, avoiding excessive mitral annulus dilation or providing a fixed diameter in other portions of the stent or housing. Two-step implantation can be accomplished by making the housing functional as a temporary valve. | 06-25-2015 |
