1. In combination, tine protector and transvenous pacing lead comprising:
- a. tine protector including four opposing walls and a bottom wall, said walls structurally connected together, a first round hole in one of said walls, and a longitudinal vertical slit and a second round hole in the other of said opposing wall, said round holes geometrically opposing each other;
b. transvenous pacing lead including an electrode axially secured to a space-wound coil covered with insulation and a plurality of outward angularly extending tines from said electrode, and;
c. said electrode frictionally engaged within and to said first hole and said space-wound coil covered with insulation of said lead frictionally engages within and to said second hole through said longitudinal vertical slit whereby said tines of said electrode lead are protected within the confines of said walls of said tine protector.

Abstract
Tine protector which protects a plurality of outwardly angular extending tines from an electrode of a pacing lead. The tine protector includes four sides and a bottom where two of the opposing sides include a first round hole in one side, and a second round hole joined to a longitudinal vertical slit in the other side. The electrode frictionally engages into the first hole, and the other electrode or lead of the pacing lead frictionally engages down through the slit and into the second hole. The tines are protected by their close proximity to these two opposing sides.

2. In combination, tine protector and coaxial transvenous leads including a fixation loop comprising:
-
a. tine protector including four structurally connected walls and a bottom wall structurally connected to said four walls, a first round hole and a second round hole and slit in two of said opposing walls geometrically and substantially geometrically aligned with each other, and; b. coaxial transvenous leads including an inner transvenous lead having a wound coil covered with insulation, a electrode axially affixed to said coil and a plurality of tines extending outwardly from said electrode, said electrode supported in said first hole of said tine protector and an outer coaxial transvenous lead having an insulation covered space-wound coil, a ring electrode actually secured to said outer coil, two tines extending outwardly from said ring electrode, and a fixation loop secured to said tines, said ring electrode supported through said slit and in said second hole of said tine protector whereby said coaxial transvenous leads are supported within each of said respective opposing walls and said tines of said electrode are enclosed and protected within the confines of said tine protector and said tines of said outer coaxial transvenous leads and said fixation loop are protected by the confines of said outer opposing wall.

4. Apparatus comprising:
-
a body implantable lead having a proximal end, having a distal tip and having a tine extending angularly outward intermediate said proximal end and said distal tip; a first support member having means for frictionally engaging said distal tip; a second support member having means for frictionally engaging said body implantable lead intermediate said proximal end and said tine whereby said tine extends angularly outward from said body implantable lead between said first support member and said second support member; and a plurality of additional support members coupled to said first support member and said second support member whereby said tine is protected.
