Abstract:
An accommodating intraocular lens (200, 300, 400) has an anterior portion (102) including an anterior viewing element (106) and an anterior biasing element (108) connected to the anterior viewing element (106). A posterior portion (104) has a posterior viewing element (118) and a posterior biasing element (120) connected to the posterior viewing element (118). The anterior and posterior biasing elements (108, 120) are connected at first and second apices (112, 116). First and second distending members (134, 136) are connected to the posterior portion (104). The first and second distending members (134, 136) extend to locations significantly anterior of an anterior side of the posterior viewing element (118).
Abstract:
Some aspects include a mechanical pump (3) which is placed in the renal artery (4) by means of a percutaneous catheter (6), surgical implantation, or other appropriate means. This pump increases blood flow through the renal artery to the kidney (12). This increased bloodflow is perceived at the level of the macula densa as increased sodium delivery to the macula densa and the juxtaglomerular apparatus, resulting in suppression of renin production from the juxtaglomerular apparatus, with consequent reduction in angiotensin II production and aldosterone levels. This decreased aldosterone and decreased angiotensin II production lead to a reduction in blood pressure.
Abstract:
Disclosed herein is a catheter for use in an emboli containment system. In one embodiment, the catheter has a tubular body with a metallic braid construction. Two lumen extend through the tubular body, the lumen being in a side-by-side configuration. One of the lumen functions as an inflation lumen, and is in fluid communication with an inflatable balloon mounted on the distal end of thecatheter. The second lumen is adapted to receive other therapeutic catheters which comprise the emboli containment system.
Abstract:
An accommodating intraocular lens (100) implantable in an eye. The lens comprises an anterior portion having an anterior biasing element and an anterior optic having refractive power (106). The lens further comprises a posterior portion having a posterior biasing element and a posterior optic having refractive power (118). The anterior optic and the posterior optic are relatively moveable in response to action of the ciliary muscle to change the separation between the optics and the refractive power of the lens. The lens has an aberration-inducing force characteristic of about 70 mg to about 115 mg to allow aberration-inducing relative movement of the optics when the lens is in the eye, thereby adding optical aberration to the lens which increases depth of focus of the lens. In one variation, the lens has an aberration-inducing force characteristic of 70 mg to 115 mg. Related methods are also disclosed.

Abstract:
An accommodating intraocular lens, comprising : an anterior viewing element; a posterior portion having a posterior viewing element said viewing elements positioned to move relative to each other along in optical axis in response to action of the ciliary muscle of the eye, wherein said anterior and posterior portions comprise a single piece of material.
Abstract:
There is disclosed an accommodating intraocular lens for implantation in an eye having an optical axis. The lens comprises an anterior portion which in turn comprises an anterior viewing element and an anterior biasing element. The lens further comprises a posterior portion which in turn comprises a posterior viewing element in spaced relationship to the anterior viewing element and a posterior biasing element. The anterior portion and posterior portion meet at first and second apices of the intraocular lens. The anterior portion and the posterior portion and/or the apices are responsive to force thereon to cause the separation between the viewing elements to change. Additional embodiments and methods are also disclosed.
