20160022961 | Devices and Methods for Accessing the Vasculature of a Patient - A steerable guide sheath system adapted for delivery into a patient's vasculature. The pull wire which is used to tension the deflectable portion of the sheath is wrapped or twisted around the axis of the sheath. | 01-28-2016 |
20150314106 | Devices and Methods for Accessing the Vasculature of a Patient - Methods for easy, atraumatic access to areas of the vasculature that are otherwise difficult to access, using steerable guide catheters constructed with components that are selected to provide optimal navigability, torque transfer, and push ability for a variety of typical percutaneous access routes. The catheter wall thickness in the deflecting segment of the guide catheter is about 1 French (⅓ mm) or less, and includes a slotted deflection tube, and this construction allows a very tight turning radius which in turn enables guide catheter access to regions of the vasculature that are otherwise inaccessible. | 11-05-2015 |
20150231368 | RADIAL AND TRANS-ENDOCARDIAL DELIVERY CATHETER - A needle-injection catheter includes a catheter body having a distal end, a proximal end, a stiff proximal portion, a flexible distal portion, and a delivery lumen extending therethrough. In a first embodiment, a straight injection needle extends coaxially from a distal tip of the flexible portion of the catheter body, and a plurality of penetration limiting elements positioned circumferentially about a base of the straight injection needle and configured to fold radially inwardly against a shaft of the needle when constrained in a tubular lumen and to extend radially outwardly when unconstrained. In a second embodiment, a helical needle extends from the distal tip of the flexible portion of the catheter body. The helical needle has at least one helical delivery lumen connected to receive an injectable substance from the delivery lumen of the catheter body. | 08-20-2015 |
20140012189 | Implant Delivery Catheter System And Methods For Its Use - Catheter systems and methods for implanting helical or dart-like implants into the myocardium or other body tissue. The catheter system includes a helix for fixing the distal end of the catheter to the myocardium, an implant held by the helix, mechanisms for driving the fixation helix into the myocardium, and mechanisms for driving the implant into the myocardium, removing the fixation helix and leaving the implant behind. The implant may be coated, filled, or made of a drug or drug eluting compound, or drug delivery matrix of any composition. | 01-09-2014 |
20130331932 | Method of Accessing a Carotid Artery of a Patient - Methods for easy, atraumatic access to areas of the vasculature that are otherwise difficult to access, using steerable guide catheters constructed with components that are selected to provide optimal navigability, torque transfer, and push ability for a variety of typical percutaneous access routes. The catheter wall thickness in the deflecting segment of the guide catheter is about 1 French (⅓ mm) or less, and includes a slotted deflection tube, and this construction allows a very tight turning radius which in turn enables guide catheter access to regions of the vasculature that are otherwise inaccessible. | 12-12-2013 |
20130331881 | Method of Implanting a PFO Occluder in a Patient - Methods for easy, atraumatic access to areas of the vasculature that are otherwise difficult to access, using steerable guide catheters constructed with components that are selected to provide optimal navigability, torque transfer, and push ability for a variety of typical percutaneous access routes. The catheter wall thickness in the deflecting segment of the guide catheter is about 1 French (1/3 mm) or less, and includes a slotted deflection tube, and this construction allows a very tight turning radius which in turn enables guide catheter access to regions of the vasculature that are otherwise inaccessible. | 12-12-2013 |
20130331819 | Method of Accessing a Contralateral Femoral Artery of a Patient - Methods for easy, atraumatic access to areas of the vasculature that are otherwise difficult to access, using steerable guide catheters constructed with components that are selected to provide optimal navigability, torque transfer, and push ability for a variety of typical percutaneous access routes. The catheter wall thickness in the deflecting segment of the guide catheter is about 1 French (⅓ mm) or less, and includes a slotted deflection tube, and this construction allows a very tight turning radius which in turn enables guide catheter access to regions of the vasculature that are otherwise inaccessible. | 12-12-2013 |
20130323212 | Treatment for Chronic Myocardial Infarct - A method of treating chronic post-myocardial infarction including helical needle transendocardial delivery of autologous bone marrow (ABM) mononuclear cells around regions of hypo or akinesia in chronic post-myocardial infarction (MI) patients. The treatment is safe and improves ejection fraction (EF). | 12-05-2013 |
20130184656 | Method of Treating the Heart - A catheter system for delivery of therapeutic substances to a depth within the heart muscle via the venous side of the heart. The system includes a reservoir of potentially embolic therapeutic agent. | 07-18-2013 |
