Medical techniques include systems and methods for administering a positive pressure ventilation, a positive end expiratory pressure, and a vacuum to a person. Approaches also include treating a person with an intrathoracic pressure regulator so as to modulate or upregulate the autonomic system of the person, and treating a person with a combination of an intrathoracic pressure regulation treatment and an intra-aortic balloon pump treatment.

Vacuum and positive pressure ventilation systems and methods for intrathoracic pressure regulation

A patient's obstructive sleep apnea is treated by identifying a patient with sleep apnea attributable at least in part to movement of a base of a tongue of the patient toward a pharyngeal wall of the patient. The tongue is stiffened by an implant sized to be placed within the tongue. A distal portion of the implant is sized to extend within the tongue from a first end near a mandibular-geniohyoid interface to a second end near a base of the tongue. A proximal portion is attached to the first end and adapted to be secured to a jaw bone of the patient following a period of healing after placement of the implant in the tongue.

Tongue implant

A patient's obstructive sleep apnea is treated by identifying a patient with sleep apnea attributable at least in part to movement of a base of a tongue of said patient toward a pharyngeal wall of said patient. The method includes identifying a region in the tongue extending from a mandibular-geniohyoid interface to the base of the tongue and stiffening a tissue of the tongue throughout the identified region.

A method for tightening a cardiac support device includes forming offsets in excess material in the cardiac support device and inserting a fastener through the offsets. A device for tightening a cardiac support device includes first and second clamp members moveable into and out of mateable engagement. Each of the first and second clamp members includes offset-forming structure.

According to one aspect of the present invention, an apparatus and related kit are disclosed for treating an airway condition of a patient. A cartridge apparatus is disclosed for use in treating an airway condition of a patient and for use in combination with a handle sized to be hand-grasped by an operator and having an actuator mechanism to be selectively actuated by said operator. The cartridge includes a implant of biocompatible material sized to be embedded within a tissue of the airway. A needle has a distal tip for penetrating into the tissue. The needle has an axially extending bore. The implant is disposed within the bore at the distal tip. The cartridge has a proximal end adapted to be coupled to the handle for the implant to be ejected from the distal tip upon actuation of the actuator. The kit of the invention includes a container including a plurality of such cartridges.

A device for engaging a heart valve prosthesis during implantation includes a hanger and a holder. The holder includes a distal engaging surface adapted for engaging the heart valve prosthesis. The hanger is used to suspend the prosthesis in packaging and may be used to manipulate the prosthesis during implantation.

A method and apparatus for treating congestive heart disease and related cardiac complications such as valvular disorders includes a constraining device placed on the heart. The constraining device is a jacket of flexible material of knit construction defining a volume between an open upper end and a lower end. The jacket is dimensioned for the apex of the heart to be inserted into the volume through the open upper end and for the jacket to be slipped over the heart. The jacket is further dimensioned for the jacket to have a longitudinal dimension between the upper and lower ends sufficient for said jacket to constrain said lower portion of the heart. The jacket adapted to be adjusted on the heart to snugly conforming to an external geometry of the heart to constrain circumferential expansion of the heart beyond. A flexible drawstring is laced through the jacket material for the knit material to be bunched together as one end of the drawstring is pulled. A releasable stay member is provided for holding the draw string in a fixed position relative to said jacket upon release of a pulling tension on the draw string with the stay member releasable in response to a resumed pulling tension on the draw string.

A surgical tool for measuring a perimeter of a heart at a location spaced from an apex of the heart includes a handle having a head having first and second sides. The head is adapted to be placed against the heart at the measurement location with the sides spaced apart along the perimeter. The head has a first slot formed in the first side communicating with an interior of the handle. The handle has a proximal end opposite the head. A second slot is formed in the proximal end communicating with the handle interior. The handle has a visibly perceptible handle marking adjacent the second slot. An elongate flexible member has a first end secured to the handle and extending from the second side of the head. The elongate flexible member is passed through the first and second slots and terminates at a free end external of the handle. The elongate flexible member has a plurality of tape markings disposed along a length of the elongate flexible member. The elongate flexible member extends out of the second slot at the handle marking for the tape markings to be in alignment with the handle marking as the flexible member is pulled through said the slot.

Device for heart measurement

A device for engaging a heart valve prosthesis during implantation includes a mechanism for attaching the device to the heart valve prosthesis. The heart valve prosthesis includes a circular valve body having an annulus with a substantially annular aperture therein. At least one movable occluder is carried in the aperture and is movable between an open position and a closed position. The attachment mechanism includes a member which couples to the circular valve body thereby affixing the device to the heart valve prosthesis. The thickness of the device which extends in a direction above the heart valve prosthesis is reduced. The device is selectively removable from the heart valve prosthesis following implantation of the prosthesis in the heart tissue annulus of a patient.

Apparatus for attachment of heart valve holder to heart valve prosthesis

A device for engaging a heart valve prosthesis during implantation includes a mechanism for attaching the device to the heart valve prosthesis. The heart valve prosthesis includes a circular valve body having an annulus with a substantially annular aperture therein. At least one movable occluder is carried in the annulus and is movable between an open position and a closed position. The occluder is carried on a strut coupled to a valve body. The attachment mechanism includes a member which couples to the strut, thereby affixing the device to the heart valve prosthesis. The attachment mechanism may be actuated to disengage the heart valve prosthesis.
