A modular catheter assembly includes a holder, having a proximal end and a distal end. An electrode sheath carrier is mounted on the distal end of the holder. A shape-imparting element carrier is removably mountable to an end of the holder and is accessible externally of the holder with at least the shape-imparting element carrier being replaceably mounted to the holder.

An implantable medical device for implantation in a recipient's body, the implantable medical device including first and second elongate leads electrically connected to first and second device components of the implantable medical device, respectively. The implantable medical device further includes a conductor connector electrically connecting a distal end of the first lead to a distal end of the second lead, and an impervious encasement insulating the conductor connector. The impervious encasement includes a sleeve circumferentially surrounding and spaced from the conductor connector and an insulative material filling the space between the conductor connector and the sleeve.

An administration set flow condition monitor (30) includes a body member (32) configured to communicate with a fluid conduit (12) of the administration set (10). A flow monitoring mechanism (40) is carried by the body member (32) for indicating flow in the fluid conduit (12) of the administration set (10). An enunciator (56, 58) is associated with the flow monitoring mechanism (40) to indicate flow condition in the fluid conduit (12) of the administration set (10).

A tissue prosthesis insertion system includes a first assembly comprising a plurality of nested tubes, one of the tubes being a carrier tube which, in use, receives a component of a tissue prosthesis at a distal end of the carrier tube. A magnetic mount is carried at a proximal end of the first assembly. A second assembly is removably attachable to the first assembly. An attachment device is carried at a distal end of the second assembly, the attachment device being responsive to the magnetic mount of the first assembly, the magnetic mount and the attachment device carrying complementary engaging formations to facilitate hermetic sealing between the magnetic mount and the attachment device.

A stent assembly (10) comprises a stent component (12). The stent component (12) includes a primary arm (14) defining a first open passage; and at least one secondary arm (16) extending at an angle from the primary arm (14), the at least one secondary arm (16) being integrally formed with the primary arm (14) as a one piece unit and the secondary arm (16) defining a second open passage in communication with the passage of the primary arm (14). An outer sheath (20) surrounds and constrains the stent component (12) in a constricted configuration to facilitate insertion of the stent component 12 into a vascular system of a patient. The outer sheath (20) is removable from the stent component (12) to enable the stent component (12) to adopt its operative configuration when the stent component (12) is at its desired position in the vascular system of the patient.

A catheter sheath 12 includes a tubular member 14 defining a lumen 18, a distal region of the tubular member 14 defining a plurality of discrete elements 28. The discrete elements 28 are displaceable between a first position in which the discrete elements 28 extend parallel to a longitudinal axis of the tubular member 14 and a second position in which the discrete elements 28 project outwardly transverse to the longitudinal axis of the tubular member 14. A plurality of electrical conductors 30 is associated with the tubular member 14, the conductors 30 projecting into the distal region of the tubular member 14. A sleeve is about the tubular member 14, the sleeve and the tubular member 14 being displaceable axially with respect to each other for effecting displacement of the discrete elements 28 between their first and second positions. At least one electrode 36 is carried by at least one of the discrete elements 28, the at least one electrode 36 being in an operative position when the discrete elements 28 are in their second position.
摘要:
An intervertebral disc implant (10) includes an envelope (12) of a stretchable and elastically deformable elastomeric material. The envelope includes an attaching formation (74) for attachment of an introducer (76) to enable the envelope, in a collapsed state, to be introduced into a volume of an intervertebral disc that has undergone a nucleotomy. A filler material (14) is receivable in the envelope via the introducer to cause the envelope to expand elastically to conform substantially to the volume in which the envelope is received.
摘要:
An implantable sitmulating lead for a cardiac pacemaker has a distal tip having a surface area adapted to physically contact heart tissue for pacing the heart tissue, sensing heart contractions and promoting tissue ingrowth. The distal tip includes a conductive electrode and a porous non-conductive substrate, which together define the surface area of the distal tip. The conductive electrode and porous substrate are provided as first and second members, although the surface area of each is adaptive to present a singular, smooth distal tip region for the electrode lead.
摘要:
Self-contained, self-powered, flexible electrical control signal generating means are located in the right ventricle of a heart and generate electrical control signals solely by mechanical movements caused by actions of and conditions in the heart without any electrical connection to and supply of electrical energy from any other power source which electric control signals are transmitted to a control circuit system of an implanted control unit which control unit transmits an electrical signal to a stimulation electrode implanted in tissue at the apex of the right ventricle of the heart which stimulation electrode uses the electrical signal to stimulate the heart.
摘要:
A catheter sheath for an irrigation catheter comprises an elongate member having a proximal end and a distal end and defining a lumen extending from the proximal end to the distal end. At least one electrode is arranged on the elongate member. A plurality of elongate elements are contained in the elongate member, the elongate elements comprising at least one electrical conductor and at least one element of a non-conductive material arranged adjacent the at least one electrical conductor to form at least one non-conductive region associated with the elongate member. At least one passage extends through a wall of the elongate member to intersect the non-conductive region and to be in communication with the lumen of the elongate member. The at least one passage has an outlet opening in, or adjacent, the at least one electrode.
