摘要:
An instrument for measuring the medullary canal of a long bone in order to determine the proper size for a stem centralizer is provided. The instrument includes an elongated central portion defining opposed first and second ends and a contact portion. The contact portion extends from the first end or the second end of the elongated central portion. The contact portion has a contact area for contact with the medullary canal and defines a relief area for providing clearance between the instrument and the medullary canal.

Surgical instruments for use in mapping tissue defects include telescoping rulers and tubes. One of the instruments has a pointed anchoring tip for piercing tissue near the site of the defect. Another instrument has a hook for catching an anatomical landmark. Measuring portions of the rulers of both instruments include distance indicia so that a coordinate system can be established for mapping the location of the defect or of an implant at the defect site. The coordinate system can be re-established at a later time using the same fixation point for the anchoring tip and the same landmark for the hook to evaluate the clinical effects of the treatment selected. The method of using the instrument set is also described.
摘要:
A surgical kit includes an applicator instrument and a needle assembly. The needle assembly provides two spaced pathways and carries a surgical fastener. One anchor of the surgical fastener is carried by one of the pathways and another anchor of the fastener is carried by the other pathway. A filament connects the two anchors of the fasteners and extends between the pathways. The applicator allows for simultaneous insertion of both anchors of the fastener at spaced locations with the filament extending from both anchors in the tissue and over the surface of the tissue or of a therapeutic implant fixated to the tissue. The needle assemblies may be removed from the applicator. The kit may include several needle assemblies that may be attached to the applicator in series to create a plurality of mattress-type stitches.
摘要:
An implantable medical device comprising a housing, a capacitor assembly, an electronics module and an energy source, such as a battery. The capacitor assembly is disposed within the housing. The electronics module is electrically connected to the capacitor assembly and similarly disposed within the housing. The capacitor assembly comprising a case, an electrode stack and an insulative liner between the case and the electrode stack. The capacitor assembly electrode stack comprising a plurality of electrode subassemblies each having a plurality of anode plates and a plurality of cathode plates with a separation layer between anode and cathode plates. The liner also maintains alignment and immobilizes the electrode stack within the capacitor assembly. Finally, the energy source is electrically connected to the electronics module. With this configuration, an overall shape and size of the implantable medical device is optimized. Methods for assembling an implantable medical device and for forming the capacitor assembly insulative liner are provided.

Surgical instruments for use in sizing tissue defects and selecting an appropriate implant for the defect include sizing templates. The sizing templates are sized and shaped to correspond to the size and shape of the implants. The sizing templates may be retractable into a tube for use in arthroscopic surgery. The retractable sizing templates are resilient to allow them to be retracted into a small diameter tube, and to expand on release from the tube to the desired size and shape. The method of using the instrument set is also described.

摘要:
A surgical instrument has a main shaft underlying a slide member. The slide member is movable in a proximal-distal direction. The distal end of the slide member has an open position and a closed position. The closed position is spaced from the open position in the proximal-distal direction. There is a gap between the distal end of the slide member and the distal end of the main shaft when the instrument is in the open position. The gap is smaller when the instrument is in the closed position. An implant can be received in the gap and delivered to a damaged tissue site using the instrument. An implant protector can be used when delivering the implant with the instrument. A pivotable implant cover can be used to protect the implant instead of the slide member.
摘要:
A surgical instrument stabilizes an implant as the implant is secured to native tissue at a damaged tissue site such as in an intra-articular space. The instrument has a proximal end portion, a distal end portion and an intermediate portion. The distal end portion has a template for guiding an attachment mechanism into the implant and the adjacent native tissue. The distal end portion can also have barbs to engage the implant to enhance stabilization of the implant. Several instruments can be provided in a surgical kit with different lengths and shapes of distal end portions. A surgical kit could also contain modular distal end portions of varying sizes and shapes. A surgical method utilizing the stabilizing instrument is also disclosed.
