An incising body defines a non-circular coaxial bore and includes a sharpened cutting edge that extends from a bottom distal end beyond the opening of the coaxial bore and an attachment point at a top distal end. A plunger is non-fixedly contained within the coaxial bore and slides longitudinally therein. A cover is pivotally attached at the attachment point and extends down to the bottom distal end and, when closed, the cover encloses the opening proximal to the cutting edge.Type: GrantFiled: July 14, 2010Date of Patent: January 8, 2013Assignee: Cardiac Science CorporationInventor: Gust H. Bardy

Patent number: 8348883Abstract: A device for implanting an object into animal tissue and a method for using the same device is provided. The device includes a cannula having a longitudinal axis, a passageway extending therethrough, a proximal end, and an opposite distal end that is insertable into tissue and defines an exit aperture for discharge of the object from the cannula. The device also includes an axially movable plunger disposed and oriented in a non-coaxial relationship within at least a portion of the cannula and a partial barrier disposed within the cannula adjacent to its distal end and configured to at least partially block the passageway, where the partial barrier at least partially defining an object receiving opening that is in communication with the passageway and sufficiently sized to receive the object and the plunger. When the device is in a first position, the partial barrier prevents the object from entering the passageway even when the plunger is inserted into the object receiving opening.Type: GrantFiled: September 30, 2009Date of Patent: January 8, 2013Inventor: Martha Sklavos

Publication number: 20120330226Abstract: Apparatus for introducing an implant into a hollow anatomical structure (HAS). The apparatus comprises a storage unit and an elongate vascular implant stored inside the storage unit and having a distal end. The apparatus further comprises a pushrod at least partially stored inside the storage unit and having a distal end coupled to the implant, and a pushrod drive unit configured to advance the pushrod distally and thereby deliver the implant. The pushrod drive unit includes a drive member having a grip portion that engages the pushrod, and an actuation portion extending from the grip portion.Type: ApplicationFiled: June 20, 2012Publication date: December 27, 2012Applicant: TYCO HEALTHCARE GROUP LPInventor: Stephen W.

Patent number: 8323232Abstract: An instrument with a two-part plunger for subcutaneous implantation is provided. An incising body defines a non-circular coaxial bore and includes a cutting edge formed on a distal end. A two-part plunger is non-fixedly contained within the coaxial bore and includes a tongue blade assembly and a plunger assembly. The tongue blade assembly is provided on a bottom surface of the coaxial bore and includes a tongue blade shaft and a thin tongue blade with a sharpened clearing edge on a distal end. The tongue blade assembly has a length exceeding the coaxial bore. The plunger assembly has a length exceeding the coaxial bore and includes a plunger shaft and a plunger affixed on a distal end. The plunger is slidably positioned on a top surface of the tongue blade.Type: GrantFiled: July 14, 2010Date of Patent: December 4, 2012Assignee: Cardiac Science CorporationInventor: Gust H. Bardy

Patent number: 8308708Abstract: A catheter-based deployment system for deploying cellular material (22) into the heart muscle (25). The deployment system includes a guiding catheter (19) and a needle assembly (31) capable of sliding within the guiding catheter. The needle assembly (31) terminates in a tip (34) having at least one side with an opening (43) in communication with a lumen (20) disposed within the needle assembly (31). Once the guiding catheter (19) is positioned, the needle assembly (31) is advanced until the tip (34) penetrates the muscle wall (25). At a predetermined depth the cellular material (22) may be deployed into the muscle wall (25) via a push rod (46) disposed through the lumen of the needle assembly (31).Type: GrantFiled: February 5, 2010Date of Patent: November 13, 2012Assignee: Abbott Cardiovascular Systems Inc.Inventors: Howard J Leonhardt, Robert D. Lashinski

Patent number: 8308678Abstract: A device for delivering a medicated product or the like to a bodily cavity is provided. The device includes a barrel member having a distal end. The barrel member is sized to contain the medicated product. The device includes a plunger sized to extend into the barrel member. A cap is adapted to move between a sealing position, in which the cap is positioned adjacent to the barrel member and seals the distal end of the barrel member, and a dispensing position, in which the cap is moved in a direction away from the barrel member. The cap includes at least one opening sized to allow the medicated product to flow through the cap when the cap is in the dispensing position. A retainer mechanism is provided for retaining the cap on the barrel when the cap is in the dispensing position.Type: GrantFiled: September 23, 2008Date of Patent: November 13, 2012Assignee: McNeil-PPC, Inc.Inventor: Paul B.
