Delivery system for a prosthesis
A method of making a delivery system for a prosthesis includes providing a catheter shaft, sliding a plurality of rings over the catheter shaft, each of the rings having an inner diameter larger than an outer diameter of the catheter shaft, fixing a pull wire to each of the plurality of rings at a common circumferential location of the catheter shaft, and coupling a sheath to the pull wire, the sheath positioned over the prosthesis at a distal end of the catheter shaft. Fixing the pull wire to each of the plurality of rings can include wrapping a heat shrink film around each of the plurality of rings and the pull wire, and heating the heat shrink material.
Mitral or tricuspid repair systems with multi-directional anchors
Prosthetic ring valve assemblies are disclosed. A prosthetic valve ring assembly includes an outer tube and a plurality of anchors. The outer tube includes a plurality of windows. The plurality of anchors are positioned inside the outer tube and about a perimeter of the outer tube. The plurality of anchors are configured to be emitted from the plurality of windows in order to anchor the prosthetic valve ring assembly to annulus tissue of a patient.
One-piece heart valve stents adapted for post-implant expansion
A prosthetic heart valve configured to replace a native heart valve and having a support frame configured to be reshaped into an expanded form in order to receive and/or support an expandable prosthetic heart valve therein is disclosed, together with methods of using same. The prosthetic heart valve may be configured to have a generally rigid and/or expansion-resistant configuration when initially implanted to replace a native valve (or other prosthetic heart valve), but to assume a generally expanded form when subjected to an outward force such as that provided by a dilation balloon or other mechanical expander.
BIFURCATED BALLOON EXPANDABLE STENT ASSEMBLY
The invention relates to a medical device, the medical device comprising a balloon catheter, a first stent, and a second stent; the balloon catheter having a shaft and an inflatable balloon mounted to the shaft at the distal end the balloon having a distal portion having a first outer diameter and a proximal portion having a second outer diameter, wherein the first diameter is smaller than the second diameter and a transition region located between the distal portion and the proximal portion, a first stent having a first nominal diameter mounted on the distal portion of the balloon and a second stent having a second nominal diameter mounted on the proximal portion of the balloon, a distal portion of the second stent overlapping a proximal portion of the first stent, wherein the proximal end of the first stent is positioned proximal to the distal end of the second stent, the medical device further comprising a pre-cannulation means providing a passage from the interior of the second stent to the exterior of the first stent passing the stent overlapping portion between the inner surface of the second stent and the outer surface of the first stent.
STENT DELIVERY SYSTEM
Stent delivery device including an inner member having a distal tip, a stent support member, and a stent disposed over a stent receiving region of the stent support member. An elongated outer sheath is slidably disposed over the inner member and the stent. The stent delivery device includes a distal junction removably coupling the distal end of the outer sheath to the distal tip, where the distal junction is actuatable to decouple the outer sheath from the distal tip. The stent delivery device includes a proximal junction removably coupling a distal portion of the outer sheath to a proximal portion of the outer sheath, where the proximal junction is actuatable to decouple the distal portion of the outer sheath from the proximal portion of the outer sheath. The distal and proximal junctions may be separately actuatable by rotating the inner member relative to the proximal portion of the outer sheath.
POSTERIOR TOTAL JOINT REPLACEMENT
A prosthetic system for implantation between upper and lower vertebrae comprises an upper joint component. The upper joint component comprises an upper contact surface and an upper articulation surface. The system further includes a lower joint component. The lower joint component comprises a lower contact surface and a lower articulation surface configured to movably engage the upper articulation surface to form an articulating joint. The articulating joint is adapted for implantation within a disc space between the upper and lower vertebrae, allowing the upper and lower vertebrae to move relative to one another. The system further includes a bridge component extending posteriorly from one of either the upper or lower joint components and from the disc space. The bridge component has a distal end opposite the one of the either upper or lower joint components. The distal end of the bridge component comprises a connection component adapted to receive a fastener.
CERVICAL SPINOUS PROCESS STAPLE
Thoracic/lumbar and cervical spinous process staples which staple/fuse adjacent spinous processes are disclosed. Thoracic/lumbar transverse process staples which staple/fuse adjacent transverse processes are also disclosed. Each embodiment has upper and lower claws connected by a ratchet spring mechanism, along with a multiplicity of bone fastener prongs attached to the upper and lower claws. Two sets of prongs on each staple claw are spaced by a distance approximately equal to the distance separating adjacent spinous or transverse processes so as to facilitate stapling/fusion of two adjacent processes. Also disclosed are staple prongs with multiple perforations which enable incorporation of bone fusion material thereby facilitating stapling/fusion of spinal elements.
REFOCUSABLE LENS SYSTEM WITH MUTUALLY-APPLANATING INTERNAL SURFACES
An accommodating (re-focusable) lens system a body of which includes, upon being assembled, first and second individual lenslets having first and second optical portions sequentially disposed along an optical axis. Change in optical-power accommodation of the system is achieved by changing an applanated area of contact between the lenslets in response to force applied to the lenslets and transformed into an axial force. In specific case, the first and second lenslets form an intraocular lens (IOL) and have respective haptic portions, interlocked as a result of rotating of one lenslet with respect to another such as to bring first and second lenslets in contact at an axial point. The applanated area of contact is changed, then, in response to a radially-directed force caused by a change of distance between the interlocked ends of the haptics and transferred to the optical portions through the interlocked haptics. When installed in a natural lens capsule after the cataract extraction, the optical power of such IOL is gradually modifiable due to a change of curvature of the capsule caused by operation of a ciliary muscle.
Intervertebral prosthesis
An intervertebral prosthesis for insertion between adjacent vertebrae includes upper and lower prosthesis plates locatable against respective vertebrae and having opposing concavely curved recesses therein, and a core located between the plates. The core has opposed, convexly curved surfaces received in the recesses of the plates to allow the plates to slide in articulated manner over the core. The opposed surfaces of the core and the recesses of the plates have cooperating spherical curvatures. The recess of each plate surrounds a locating peg projecting centrally from the base of the recess and is bounded by an annular rim, such that the annular rims of the plates are arranged to contact one another at a predetermined limit of sliding movement of the plates over the core. The peg locates loosely in an opening located centrally in a curved surface of the core, whereby the plates can slide over the core in all directions while the peg holds the core captive.
