Publication number: 20110270389Abstract: A device and method for forming an adaptive optic in the capsule of a human eye is disclosed, comprising a capsular interface enclosing an optically acceptable medium. The device establishes a physiologic range of optical power in response to a range of ciliary contractile states. The preferred bi-phasic medium of the device is comprised of a solid three dimensional polymeric network suspended in a liquid aqueous phase and bonded to a capsular interface. The polymeric network provides shape to the capsular interface, optical power, and a physiologic response to the suspensory ligament. The three dimensional network of the bi-phasic medium mimics the stacked fiber configuration and elasticity of a natural lens. An alternative embodiment utilizing a single phase medium is also disclosed with associated structural features provided in the capsular interface.Type: ApplicationFiled: April 28, 2011Publication date: November 3, 2011Inventors: Liane Clamen Glazer, Paul Glazer, Michael T.

Publication number: 20090304773Abstract: The present invention provides a liquid polymer composition which can be implanted into a living mammal and which forms a solid hydrogel by in situ polymerization upon contact with body fluid and tissue. The composition also can be used as a coating on a medical device, or for the formation of a medical device. Formation of a solid implant or coating involves crosslinking of the adhesive with itself and with surrounding tissue. The liquid implant, by itself or in conjunction with various prostheses, can be used for many purposed, including fixation of the urethra for providing treatment for incontinence, and repair of herniations in the abdominal cavity, including rectocele, cystocele, enterocele, and inguinal hernia. The adhesive may be used to establish adhesion prevention during such repairs, in part by coating or being the material of a repair mesh.Type: ApplicationFiled: August 17, 2009Publication date: December 10, 2009Applicant: Promethean Surgical Devices, LLCInventors: Michael T.

Patent number: 6846296Abstract: Methods and apparatus are disclosed for attaching cardiac devices onto a natural heart by employing arrays of gripping elements, such as hooks or barbs. The gripping elements are designed to penetrate and lodge themselves in the epicardial tissue in order to secure the device to at least a portion of the surface of the heart muscle. The gripping elements, although designed to penetrate the surface of the heart, have limited depth penetration so as to avoid puncture of blood vessels. The attachment mechanisms disclosed herein can also permit both attachment and detachment of device.Type: GrantFiled: September 14, 2000Date of Patent: January 25, 2005Assignee: Abiomed, Inc.Inventors: Michael T.

Patent number: 6626821Abstract: A flow-balanced cardiac wrap that assists the right and left ventricles of an affected heart to differing, and adjustable degrees is provided. The wrap generally applies an assist to the left ventricle that is greater than that applied to the right, or that reduces blood output from the right relative to the left. In one embodiment, the wrap comprises a material covering that is applied around the right and left ventricles of the heart, so that the left ventricle is assisted over a larger surface area than the right. The positioning of the right ventricular portion or the wrap is chosen so that desired pumping characteristics for the right ventricle are achieved.Type: GrantFiled: May 22, 2001Date of Patent: September 30, 2003Assignee: ABIOMED, Inc.Inventors: Robert T. V. Kung, Michael T. Milbocker

Patent number: 6616596Abstract: A unified, non-blood contacting, implantable heart assist system surrounds the natural heart and provides circumferential contraction in synchrony with the heart's natural contractions. The pumping unit is composed of adjacent tube pairs arranged along a bias with respect to the axis of the heart and bound in a non-distensible sheath forming a heart wrap. The tube pairs are tapered at both ends such that when they are juxtaposed and deflated they approximately follow the surface of the diastolic myocardium. Inflation of the tube pairs causes the wrap to follow the motion of the myocardial surface during systole. A muscle-driven or electromagnetically powered energy converter inflates the tubes using hydraulic fluid pressure. An implanted electronic controller detects electrical activity in the natural heart, synchronizes pumping activity with this signal, and measures and diagnoses system as well as physiological operating parameters for automated operation.Type: GrantFiled: November 28, 2000Date of Patent: September 9, 2003Assignee: Abiomed, Inc.Inventor: Michael T.
