Patent number: 8696564Abstract: All or a portion of a surface of an implantable sensor is covered with a biocompatible coating formed at least partially of a biomaterial matrix having properties that promote a substantially even growth of tissue cells over the surface of the coating. Additional materials, such as growth factors, agents that recruit endogenous stem cells, and cell adhesion motif arginine, glycine, aspartic acid may be included in the coating. Autologous cells may be added to the coating prior to implantation. The sensor surface may also be textured, by etching or abrading, in order to promote even tissue growth. Alternatively, the sensor surface may be covered with a coating having properties that inhibit the growth of tissue. These coatings may include a biomaterial, a biomaterial matrix having a drug, such as a sirolimus or a steroid, an active component, or a self assembled monolayer.Type: GrantFiled: July 9, 2004Date of Patent: April 15, 2014Assignee: Cardiac Pacemakers, Inc.Inventors: Abhi Chavan, Jeffrey Ross, Cynthia Morrissey, Scott Mazar, Donald Palme

Publication number: 20060122522Abstract: Methods and systems provide for anchoring implantable medical device inside a bodily vessel. An anchoring structure can include a stent-like structure to which the IMD is attached. The stent-like structure is positioned at a desired location in the bodily vessel. The stent-like structure can be repositioned based on a measurement from the IMD. The IMD can include outwardly extending fins over which tissue can fibrose to affix the IMD to a wall of the bodily vessel. The stent-like structure can be made of a bio-absorbable material. The IMD can be attached to a stent-like structure by leads, by being lodged in a recessed diaphragm, by being embedded in mesh of the stent-like structure, or other methods. The stent-like structure can be balloon deployable to allow for controlled positioning and anchoring. The anchoring structure can include a vena cava filter.Type: ApplicationFiled: August 31, 2005Publication date: June 8, 2006Inventors: Abhi Chavan, Jeffrey Von Arx, Bruce Tockman, Donald Palme

Publication number: 20050228217Abstract: A jacket of biological compatible material has an internal volume dimensioned for an apex of the heart to be inserted into the volume and for the jacket to be slipped over the heart. The jacket has a longitudinal dimension between upper and lower ends sufficient for the jacket to surround a lower portion of the heart with the jacket surrounding a valvular annulus of the heart and further surrounding the lower portion to cover at least the ventricular lower extremities of the heart. The jacket is adapted to be secured to the heart with the jacket surrounding at least the valvular annulus and the ventricular lower extremities. The jacket is adjustable on the heart to snugly conform to an external geometry of the heart and assume a maximum adjusted volume for the jacket to constrain circumferential expansion of the heart beyond the maximum adjusted volume during diastole and to permit unimpeded contraction of the heart during systole.Type: ApplicationFiled: June 3, 2005Publication date: October 13, 2005Applicant: Acorn Cardiovascular, Inc.Inventors: Clifton Alferness, Donald Rohrbaugh, J.

Publication number: 20050137674Abstract: The present invention is a myocardial lead attachment system for securing a lead within the myocardium. The attachment system includes an anchor configured to engage the heart, a tether coupled to the anchor and a lead body. The lead body has a proximal end, a distal end, a lumen for accepting the tether and a lock housing in the lumen. A lock structure is on the tether and mates with the lock housing and restrains motion of the lead with respect to the tether in either of a proximal or a distal direction.Type: ApplicationFiled: October 22, 2004Publication date: June 23, 2005Applicant: Cardiac Pacemakers, Inc.Inventors: M.
