Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
175 words
A pacing and sensing catheter device for use within body cavities, comprising: an elongated tubular assembly formed at a forward end thereof with a probe portion adapted to be inserted into and moved within said body cavities, said tubular assembly being further formed at a rearward end thereof with means communicative with said forward end for receiving a fluid; said probe portion including spaced proximal and distal members and proximal and distal electrodes secured to said proximal and distal members, respectively; a first conductor electrically connected to said proximal electrode, a second conductor electrically connected to said distal electrode, and said first and second conductors being electrically insulated from each other; inflatable means formed of an elastic material secured to and interconnecting each of said spaced proximal and distal members; and said inflatable means, comprising a balloon member adapted to be inflated upon fluid introduced under pressure through said fluid receiving means, whereby the forward end of said probe portion is resiliently mounted for inhibiting the transfer of forces between said proximal and distal members.
Claim 2
Dependent Claim
175 words
A pacing and sensing catheter device for use within body cavities, comprising: an elongated tubular assembly formed at a forward end thereof with a probe portion adapted to be inserted into and moved within said body cavities, said tubular assembly being further formed at a rearward end thereof with means communicative with said forward end for receiving a fluid; said probe portion including spaced proximal and distal members and proximal and distal electrodes secured to said proximal and distal members, respectively; a first conductor electrically connected to said proximal electrode, a second conductor electrically connected to said distal electrode, and said first and second conductors being electrically insulated from each other; inflatable means formed of an elastic material secured to and interconnecting each of said spaced proximal and distal members; and said inflatable means, comprising a balloon member adapted to be inflated upon fluid introduced under pressure through said fluid receiving means, whereby the forward end of said probe portion is resiliently mounted for inhibiting the transfer of forces between said proximal and distal members.
Claim 3
Dependent Claim
24 words
The device according to claim 1, wherein said first and second electrical conductors are elongated and extend in spaced relationship within said tubular assembly.
Claim 4
Dependent Claim
40 words
The device according to claim 2 for use with remote heartbeat pacing apparatus, further comprising first and second electrical connectors secured to said first and second conductors, respectively, for electrically interconnecting said proximal and distal electrodes with said remote apparatus.
Claim 5
Dependent Claim
92 words
The device according to claim 3, wherein said proximal and distal members comprise spaced segments of said elongated tubular assembly, said proximal member being substantially longer than said distal member and being formed with a forward end which defines an opening communicative with interior walls of said balloon member, said distal member extending between forward and rearward ends thereof which define foward and rearward openings, respectively, the forward end of said proximal member and the rearward end of said distal member being disposed in variably juxtaposed relationship with respect to one another.
Claim 6
Dependent Claim
30 words
The device according to claim 4, wherein said balloon member is secured to and extends between outer annular surfaces of said proximal and distal members adjacent the juxtaposed ends thereof.
Claim 7
Dependent Claim
119 words
The device according to claim 5, wherein said proximal electrode comprises an annular platinum sleeve secured to the outer surface of said proximal member, said proximal member being formed with an aperture through which said first electrical conductor extends to said proximal electrode, said distal electrode comprising a cup-shaped platinum member surrounding the forward end of said distal member and being secured to the outer annular surface of said distal member, said second electrical conductor extending from within said proximal member through the rearward and forward ends of said distal member, and being electrically connected to said cup-shaped distal electrode by a soldered deposit disposed within and in electrical contact with the inner portion of said cup-shaped distal electrode.
Claim 8
Dependent Claim
31 words
The device according to claim 1, wherein said fluid receiving means comprises an adaptor formed with an opening which is adapted to matingly accept an end of a fluid bearing conduit.
Claim 9
Dependent Claim
30 words
The device according to claim 7, further including a vented syringe adapted to be sealingly connected to said fluid bearing conduit for pressurizing said balloon member to a pre-determined value.
