A heart valve implant according to one embodiment may include a shaft and an anchor disposed on one end of the shaft, the anchor configured to engage tissue. The heart valve implant may further include an expandable member disposed over at least part of the shaft, the expandable member comprising a resiliently deformable internal layer and a resiliently deformable external layer disposed over the internal layer, the expandable member defining a chamber and being configured to receive an inflation medium in the chamber to expand the expandable member, the expandable member further configured to deform upon contact with at least a portion of at least one leaflet of a heart valve to at least partially conform to the shape of the leaflet.

A heart valve implant may include a shaft extending generally along a longitudinal axis of the heart valve implant. A spacer may be coupled to the shaft between a first and a second end region of the shaft. The spacer may be configured to interact with at least a portion of at least one cusp of a heart valve to at least partially restrict a flow of blood through the heart valve in a closed position and at least one anchor may be configured to be coupled to the first end region of the shaft. At least one safety stop may extend generally radially outwardly from the longitudinal axis of the heart valve implant beyond at least a portion of an outer perimeter of the spacer. The safety stop may include a cross-section which is greater than a cross-section of the heart valve in at least one dimension. The safety stop may also be configured to at least partially restrict a movement of the heart valve implant with respect to the heart valve in at least one direction.

A method according to one embodiment may include providing a heart valve implant including an anchor capable of engaging coronary tissue, a shaft coupled to said anchor, and a valve body coupled to said shaft. The method may further include at least partially collapsing the heart valve implant and percutaneously inserting the heart valve implant into a heart. The percutaneously inserted implant may be secured within the heart and may then be expanded. Of course, many alternatives, variations, and modifications are possible without departing from this embodiment.

A system for positioning an element relative to an articular surface. An embodiment of the system may include a first element having a positional reference relative to an articular surface. The system may further include a second element capable of indicating the positional reference of the first element relative to said articular surface. Of course, many alternatives, variations, and modifications are possible without departing from this embodiment.
摘要:
A implantable hemodialysis port including a housing and a septum. The housing is formed from a flexible material and includes a plurality of chambers. The chambers are fluidly interconnected with one another by integrated outlet passageways. Each of the chambers include a sidewall portion and a funnel portion tapering from the sidewall portion. The septum encloses each of the chambers.
摘要:
An access port for providing subcutaneous access to a patient, and a method of identifying a subcutaneously implanted access port. The access port includes a body capturing a septum that covers a cavity defined by the body, and a pattern of protrusions extending from an outer surface of the septum away from the cavity, the pattern of protrusions detectable through palpation to identify the access port as a power-injectable port.
摘要:
A method for visualizing the interior of a bodily passageway comprising providing a system comprising a plurality of concentric telescoping shafts; visualization apparatus disposed within the telescoping shafts; and a helical thread disposed on the exterior of the telescoping shafts, the helical threads having a sufficient structural integrity and surface profile such that when the telescoping shafts are disposed in the passageway, rotation of the telescoping shafts induces a relative movement between the telescoping shafts and the passageway; wherein the telescoping shafts are configured to be selectively coupled together and de-coupled from one another; inserting the system into the passageway; rotating the telescoping shafts so as to draw the passageway onto the telescoping shafts in a pleating fashion; de-coupling the telescoping shafts; rotating the innermost telescoping shaft so as to draw the passageway onto the innermost telescoping shaft in a pleating fashion; and visualizing the interior of the passageway.

摘要:
A septum for use in access port for providing subcutaneous access to a patient is disclosed. More particularly, a septum including at least one topographical feature configured for identification of the septum is disclosed. An access port including such a septum is also disclosed. In addition, an access port comprising a septum and a means for identification of the septum is disclosed. Also, a method of identifying a subcutaneously implanted access port is disclosed. Specifically, an access port including a septum may be provided and at least one topographical feature of the septum of the access port may be perceived. The subcutaneously implanted access port may be identified in response to perceiving the at least one feature of the septum of the access port.
